1.1 FEATURES
The ESL Model 2501 Fire Alarm Control Panel (FACP) is
designed to provide a reliable and cost-effective means of
implementing a fire alarm system compliant with the
requirements of the National Fire Alarm Code for pro-
tected premises fire alarm systems in commercial,
industrial, residential and institutional applications. The
ESL Model 2501 Fire Alarm Control Panel is a modular
system. In its simplest configuration, called the 2501
FACP, it consists of an enclosure, power supply and Basic
Master Board (BMB). The 2501 provides all of the
required basic system functions for alarm, fault (trouble)
and supervisory monitoring, together with one initiating
zone circuit and two notification appliance circuits. Its 7
amp, 24 VDC, system power supply provides ample
current for most applications; with 1.5 amps available
from each of the two integral notification appliance
circuits, 1.0 amp available from the auxiliary power
supply terminals (24 VDC, 0.5 amps 12 VDC in battery
saver mode) and the remaining 3 amps, available as two
additional notification appliance circuits, when a 2500
BELL Card is added to the system.
The unique modular design makes it easy to add features
when they are needed. These include a remote interface
keypad, remote annunciator, digital communicator, LEM/
LRM, extra control relays, additional notification appli-
ance circuits and additional initiating device circuits. Up
to 24 Class B, Style B initiating device circuits can be
added to the 2501 basic unit if needed. Furthermore, the
ESL 2501 Fire Alarm Control Panel is equipped with a
Remote Keypad Port. This allows the use of an optional
ESL 2500 Keypad for enhanced user interface.
One enclosure is used for most system configurations. One
cabinet can hold up to 3 expander modules, as well as the
necessary standby batteries for either 24 or 60 hour
operation. The three (3) expander modules provide up to
twelve (12) Class B zones plus one (1) from the BMB for a
total panel configuration of thirteen (13) Class B zones. To
accommodate system configurations beyond 13 zones, a
second enclosure can be installed. For larger installations,
the panels can be networked using non-latching zones or
the power booster option to provide maximum system
flexibility.
The versatility of the ESL 2501 Fire Alarm Control Panel
is further enhanced by its compatibility with the complete
line of ESL smoke detectors, manual fire alarm stations
and notification appliances. This allows the assembly of a
complete fire alarm system from components produced
by a single manufacturer with designed-in compatibility
and reliability. See Appendix A for the list of UL Listed
compatible devices.

SYSTEM CONFIGURATIONS
2.1 2501 (FACP)
The basic version of the 2501 Fire Alarm Control Panel
can be expanded to accommodate up to 25 Class B, Style
B initiating device circuits. Figure 1.4 presents in tabular
form the number of Expansion Boards of each type
needed to attain a given number of initiating device
circuits.
The 2501 (FACP) can be enhanced by adding two
additional notification appliance circuits (NAC) with the
2500-BELL expansion card. This card adds two addi-
tional bell circuits and allows use of the full 7 amps of 24
VDC power available from the 2501 (FACP) power supply
(6 amps are used for the notification appliance circuits
(NAC), up to 1 amp is used for auxiliary power).
Further enhancement of the 2501 (FACP) is provided by
the (2500-ZRM2) or (2500-ZRM4) zone follower relay
cards. These add-on cards provide SPDT relays rated 30
VDC at 2 amps resistive in a zone follower configuration.
These relay contacts are “dry” and, hence, unsupervised.
They should only be used in conjunction with a super-
vised circuit or to control non-critical or “fail-safe”
functions.
A printed copy of the events that occur in the 2501
(FACP) can be obtained by the addition of the ZXPTR
printer interface module. The BMB and DAC function
maps can be printed when this module is installed. This
module allows a standard printer with a Centronics
interface to be connected to the 2501 (FACP). Events will
be printed as they occur or the entire event history can
be printed at the user’s discretion.
The 2500-KPD LCD keypad may be added to the 2501
(FACP) to program all the system functions and allow for
on premises remote panel manipulation. Up to 3 super-
vised keypads and 1 unsupervised keypad may be added.
The 2500-KPD LCD keypad gives you access to additional
functionality of the 2501 (FACP). The keypad also allows
access to the event history and programming and testing
of other system peripherals. Access to all critical items
are restricted by the use of passcodes to prevent access
by non-authorized users.
For localities requiring remote annunciators, the 2500-RA
and 2500-RADVR can be added. Up to four devices can
be added. Each device is configurable for zones 1-13 or
zones 14-25 and all devices are supervised. The device
indicates the system status and the zone status on a zone
by zone basis. In addition to these capabilities, the
RADVR has low current (sinks up to 40mA) active low
zone follower outputs. These outputs are intended to

If the facility to be protected requires more than 25
initiating device circuits in order to fulfill the owner/
operator’s fire protection objectives, ESL 2501 control
panels can be connected together in what is commonly
referred to as a “master-slave” configuration. One unit is
designated the “master” and the other acts as the “slave”.
One initiating device circuit on the “master” unit is
programmed as a non-latching initiating device circuit
(See Section 5) and the wiring for this circuit is con-
nected to the general alarm-operated and trouble-
operated contacts of the “slave” unit BMB. This wiring
connection is illustrated in Figures 2.3a and 2.3b. Any
initiating device circuit of the “master” unit can be used
to receive signals from the “slave” unit in this manner.
When a detector initiates an alarm on an initiating device
circuit of the “slave” unit, its alarm-operated contacts
transfer and, hence, appear as a shorting contact initiat-
ing device alarm initiation at the “master” unit. The
interconnection between the master and slave units is
supervised and the End Of Line (EOL) resistor (provided)
MUST BE INSTALLED, as shown. Refer to Figure 2.3a for
installation wiring as a Master-Slave panel and Figure 2.3b
for installation wiring with a ZEM.
The Master-Slave configuration may also be implemented
with a power boost capability. This configuration is used in
applications where a local networked system is desired.
Refer to Figure 2.3c for the installation wiring. After the
installation wiring is accomplished, the panel must be
programmed as indicated on the wiring installation diagram
(see Section 5). The Master-Slave configuration will now
operate in the following manner. All zone inputs on the
Master are dedicated for Slave panel operation. Program all
bell outputs as required to meet your system design
requirements. In the Zone Bell Definition Table for each
Slave panel, program all Bells associated to Zone 1 only. In
this configuration, an alarm condition on a Slave unit will
communicate through its Alarm and Trouble dry contacts
that the Slave is in alarm. The Master will signal through
the Bell outputs that the system is in alarm and all system
bell outputs (Slaves and Master) will activate. The only
method to silence the system bells is to activate the Alarm
Silence on the Master unit. This will result in the bells
silencing on all panels. The Master will indicate on board its
control board that the bells are silenced by illuminating the
bell silenced LED. A Slave panel cannot be locally silenced.
The previous description covers all of the necessary wiring
for a Master panel to supervise and report the conditions of
up to 25 other Slave panels, allowing for very large system
coverage and expansion when needed.
2.3 SYSTEM NETWORKING
2.2 POWER BOOST
With the adoption of the Americans with Disabilities Act
(ADA) it has become necessary to provide equivalent fire
alarm notification for those with hearing impairments.
This requirement is usually addressed with visible
notification appliances (strobe lights). Frequently,
existing systems cannot provide sufficient current to
operate all of the visible notification appliances necessary
to comply with the ADA and a “power booster” is needed
to provide additional notification appliance power. The
base model 2501 can be connected to be an add-on power
booster for any UL Listed fire alarm control panel including
the 2501 (FACP). Power Booster terminals are a feature of
the panel. The panel will act as a 3 amp (NAC) power
booster with two notification appliance circuits. With the
addition of the 2500-BELL to the base model, two more
notification appliance circuits are added providing a 6 amp
(NAC) power booster with four notification appliance
circuits. See Figure 2.2 for Power Booster wiring.
In the power booster configuration, an alarm on the master
fire alarm control panel will activate an alarm on the power
booster fire alarm control panel. Interconnect wiring is
supervised and will generate a system trouble on the master
panel if the interconnect wiring is compromised. Any
system trouble on the power boost panel will generate a bell
and system trouble on the master panel. The interconnect
loop will generate a bell and system trouble at the Master
panel if the wiring should become compromised.
interface with MPI-206 Accessory Relay Boards or
similarly isolated devices for driving graphic displays as
desired or where mandated by local authorities.
For localities that utilize Listed Master Boxes in a
municipal system, the 2500-LEM/LRM can be installed.
This device provides the required connectivity to the
Listed Master Box. The connection is supervised and will
automatically restore when the master box is reset. In
addition, the module can be configured as a Line Reversal
Module for applications that require this functionality.
The connections are also supervised and auto-restore
when the device or connections are returned to a normal
state.
Another enhancement to the 2501 FACP is the 2500-
DAC, Digital Alarm Communicator. This is a full featured
DAC that reports all system events in the following
selectable formats: Pulse - 20 baud extended, Pulse - 20
baud non-extended, Pulse - 40 baud extended, SIA,
Contact ID, and Pager. The DAC is programmable with a
2500-KPD. Front panel programming is not supported. In
addition to these report formats, the DAC accepts two
supervised phone lines. For remote programming
capabilities, contact Sentrol Technical Services at 1-800-
800-2027.

2.4 DOOR HOLDERS
The 2501 (FACP) is suitable for door holder applications.
See Figure 2.4 for Door Holder Installation.
Battery saver mode is not allowed when using door
holders. They are rated for 24 VDC operation only with
the 2501 (FACP). The 2501 should be programmed (see
Section 5) so that the common trouble contacts transfer
on loss of AC only. This will release the door holders on
loss of AC. The door holders will also release on alarm.
No electronic or electrical system can be expected to
operate properly if there is insufficient electrical power.
For this reason the National Fire Alarm Code (NFPA 72)
requires that fire alarm control panels have both a
primary and secondary source of electrical power, usually
a dedicated 110 VAC branch circuit and battery back-up.
If the 110 VAC electrical power is lost AND the system
has been operating on battery secondary power for an
extended period of time, beyond that contemplated by the
code, eventually the battery set will become depleted.
Under these conditions the fire alarm control panel can
no longer be expected to operate reliably. This will occur
when the battery voltage is at 19.0 VDC. The panel will
automatically log the event and then go into hibernation
mode. While in hibernation, the 2501 (FACP) will not
2.5 LOW BATTERY ANNUNCIATION
The 2501 (FACP) will automatically perform a battery
check 15 seconds after power up. If the voltage of either
battery is below 11.0 VDC, the 2501 (FACP) will illumi-
nate the System Trouble and the No/Low Battery Trouble
LEDs and sound the trouble sounder. When the voltage of
either battery drops below 10.5 VDC, the 2501 (FACP)
will log the condition to the event log. The 2501 (FACP)
will not record a restoral unless both battery voltages
return to a value above 11.0 VDC. After the initial power
up battery test, the 2501 (FACP) will perform the same
battery test every hour. If the batteries are disconnected
after the power up battery test, the 2501 (FACP) will
illuminate the System Trouble and No/Low Battery
Trouble LEDs and sound the trouble sounder within 10
seconds.
The 2501 (FACP) will not perform a scheduled battery
test while the notification appliances (NAC) are active. It
will perform the battery test after the notification
appliances become inactive.
To force a battery test, press the SYSTEM RESET push-
button. The 2501 (FACP) will automatically perform a
battery test 10 seconds later.
2.6 HIBERNATION MODE
A drill test may be performed by providing a dry contact
closure between the Drill Test terminal and the Negative
terminal. The ESL 2501 will sound the NACs with the
programmed cadences. The communicator will not be
activated and the common alarm and trouble contacts are
not activated. An event is not generated in the event log.
2.7 DRILL TEST
The trouble sounder has a default resound interval of 15
minutes. It may be programmed to three additional
values: 1, 4, or 24 hours. See Section 5.0 Programming.
2.8 TROUBLE RESOUND TIME
detect any alarms or other troubles and the notification
appliances will not sound.
The 2501 (FACP) will indicate hibernation mode by
flashing the yellow LOW/NO AC and LOW/NO BATT LEDs
at one (1) second intervals, the SYSTEM TROUBLE LED
will be illuminated, and the local sounder will emit the
trouble sound.
The panel will automatically exit out of hibernation mode
and return to normal operation when the Low/No AC
condition is restored. After normal operating power has
been restored, the panel will continue to indicate that it
had been in hibernation by illuminating the SYSTEM
TROUBLE LED and sounding the trouble sounder until a
SYSTEM RESET is performed.
2.9 COMM TEST
When the system uses a 2500-DAC Digital Alarm Commu-
nicator, an automatic comm test is performed every 24
hours as a minimum. The system can be programmed for
a longer comm test interval if desired. The system
automatically toggles between phones so that each phone
line is tested at least once every 48 hours.
2.10 DUAL LRM OPERATION
For localities requiring dual Line Reversal Module
applications, the 2501 FACP can be programmed to
transmit separate supervisory and alarm signals. This is
accomplished with the 2500-BELL expansion module.
The FACP is programmed to operate the Bell expansion
module as a dual LRM. Bell 3 will activate for a fire alarm
and Bell 4 will activate for a supervisory alarm. For a Fire
Alarm, the Bell 3 output circuit will reverse transmitting
11
Sentrol 1-800-547-2556Sentrol 1-800-547-2556
the alarm signal to the connected device. All other
System Alarm functions are as required. For a Supervi-
sory Alarm, the Bell 4 output circuit will reverse transmit-
ting a Supervisory Alarm to the connected device. All
other Supervisory Alarm functions are as required. See
Section 5 for programming information. See Figure 2.10
Dual LRM Installation Diagram for installation informa-
tion. The connections are supervised and will result in a
System and Bell 3 and/or Bell 4 Trouble if the lines are
compromised. For system trouble transmission, the
System Trouble dry contacts are available.
2.11 GROUND FAULT INDICATION
OPERATION
The FACP is equipped with ground fault detection
circuitry. If required, the ground fault detection circuitry
may be disabled by programming the BMB. Refer to
Section 5.0 Programming for assistance with program-
ming this feature. The FACP will function normally in the
presence of a ground fault. Some localities are required
by local jurisdiction to annunciate this condition.

GENERAL SYSTEM
INSTALLATION GUIDELINES
First and foremost, CAREFULLY READ AND MAKE
SURE YOU UNDERSTAND THE ENTIRE MANUAL
BEFORE BEGINNING THE INSTALLATION. The
reliable performance of the fire alarm system is depen-
dent upon proper system design, installation and mainte-
nance.
Before installing the panel, a fire alarm system must be
designed. The design of fire alarm systems is often
regulated by the state or municipality through legislation
requiring fire alarm system designers be certified or
licensed. Make certain that the design and designer of the
system comply with the relevant local laws, regulations
and building codes and sub-codes.
The design of a fire alarm system requires a thorough
evaluation of the fire hazards and risks inherent in the
facility to be protected. The design of the fire alarm
system must also reflect the explicit fire safety objectives
of the owner/operator of the site. The design of the fire
alarm system must comply with the minimum compli-
ance requirements in the relevant local codes and
regulations. These local codes and regulations usually, by
reference, adopt the National Fire Alarm Code. Conse-
quently, the fire alarm system design must also comply
with the applicable edition of the National Fire Alarm
Code, NFPA 72; available from the National Fire Protec-
tion Association, 1 Batterymarch Park, Quincy, MA
02269-9101, tel: 1-800-344-3555. Also, if questions arise
call Sentrol Technical Services at 1-800-800-2027.
The design of the system includes:
The type, quantity and location of alarm initiating
within the facility being protected.
The type, quantity and location of alarm notification
appliances, both audible and visible, within the
facility being protected.
The connections between the fire alarm system and
other building systems such as the HVAC system,
door closers, elevator controls and security systems.
The programmed system response to alarm signals
for each initiating device or notification appliance
circuit.
The type, size and installation method of the wiring
conductors interconnecting system components.
The type, size and installation method of the wiring
conductors connecting the fire alarm system control
unit to the primary power supply.
The capacity of the fire alarm system secondary
power supply (battery set).
A dedicated, locked and labeled branch circuit (un-
switched) for primary power supply.
All design criteria should be documented in the system
design. Sentrol has provided a number of design aids in
The ESL 2501 Fire Alarm Control Panel has been
designed to be easy to install. Below we have outlined an
installation procedure that will lead to timely completion
of the installation and result in trouble-free operation.
Step 1. Planning: Referring to Figure 3.0, ESL 2501 Fire
Alarm Control Panel Interconnection Diagram, for
specific guidance, prepare a carefully laid-out and
complete wiring diagram of the entire system as designed.
This drawing should show the point-to-point connections
being made to all fire alarm system devices, including, but
not limited to: smoke detectors, manual fire alarm boxes,
fire alarm notification appliances (both visible and
audible), sprinkler system supervisory devices, sprinkler
system waterflow initiating devices and the connection to
the off-premises fire alarm signal receiving station, if
included in the system design. This wiring diagram
should show the calculations used for computing the
capacity of the battery secondary power supply according
to the Battery Calculation Worksheet, provided in
Appendix B. All drawings and calculations should be
maintained as part of the permanent record of the fire
alarm system installation. All power-limited connections
must be made with component recognized energy limited
cable.
Step 2. Equipment Inspection: Carefully unpack the
system components and inspect for damage incurred in
shipping. Immediately report any damage to the place of
purchase for disposition.
Step 3. Mount Cabinet: Mount the cabinet in a clean,
dry, vibration free area, where the temperature range
does not exceed 0 to 49oC (32 to 120oF). Mount only in
interior locations. Allow adequate space for 180 degree
door swing and free access to all sides for conduit entry.
Locate the top of the cabinet approximately six (6) feet
above the floor, with the hinge mounting on the left.
Mounting holes in the back of the cabinet are designed so
the cabinet can be mounted without removing any
control equipment. Mount the cabinet to the wall by first
installing the top center mounting screw leaving enough
space so the cabinet can be hooked over the screw head.
Use screws or bolts no smaller than #10 or 3/16 inches in
diameter. For easier access, remove the door by gently
lifting it from the hinges.
3.1 GENERAL INSTALLATION PROCE-
DURE
this manual. Figure 3.0, 2501 (FACP) Interconnect
Diagram, identifies the intended use for each wiring
terminal. Section 5 provides instructions for program-
ming the FACP. Section 10 provides a review of the
design of household fire warning systems. Appendix B
provides a battery secondary power supply calculation
worksheet. Additional design guidance is available from
the local building code, local fire code and the National
Fire Alarm Code, NFPA 72.

Sentrol 1-800-547-2556Sentrol 1-800-547-2556
Step 4. Install Fire Alarm System Devices: Refer to the
installation instructions provided with the compatible fire
alarm system devices (smoke detectors, heat detectors,
manual fire alarm boxes, audible notification appliances,
visible notification appliances and other similar devices)
and install these devices as permitted by their installation
instructions. Note that the UL Listing of some devices
permits their installation without a junction box if also
permissible under the local building code. Also note that
the installation of fire alarm systems is covered in Article
760 of the National Electrical Code (NEC), NFPA 70.
Article 760 of the NEC stipulates the types of wire
permissible for fire alarm installations employing conduit
as well as those using Listed Fire Alarm Cable. The
initiating device circuits and notification appliance
circuits are power-limited circuits. Use an installation
method permitted by Article 760 of the NEC to connect
fire alarm devices to the fire alarm system control panel.
Keep in mind that where ever conduit or cable enters a
junction box or electrical enclosure it must be provided
with a Listed bushing or connector, as appropriate. Refer
to Section 4.1, Detail Installation Guide, for further
information. DO NOT connect field wiring until after the
fire alarm control unit has been properly checked.
Step 5. Physical Assembly Check: Verify that all boards
are properly snapped into place over the locking clip. To
add a board to the panel, firmly press the board onto the
standoffs until the board snaps over the locking clip. To
remove a board from the standoffs, press the locking clip
in with needle-nose pliers or a flat head screwdriver (see
Figure 3.1a).
Examine the installation of all modules, chassis, and
subassemblies to insure proper mechanical and electrical
connections and programming switches have been
selected.
Step 6. Basic 2501 System Check: Prior to connecting
field wiring to the unit, it is necessary to make certain
that the 2501 is operating properly. This is achieved by
performing the System Check.
Install the 2.7k 5% End of Line (EOL) resistor (provided)
to Zone 1, BELL 1 and BELL 2. Make sure all switches are
PRESS
in their normal positions. Connect the power supply cable
assemblies between the BMB and power supply. Connect
the AC flying leads to an unswitched 120 VAC 50/60 Hz
power supply. See Figure 3.0, 2501 (FACP) Interconnect
Diagram. Connect the red wire to the positive (+) spade lug
of Battery 1 and the black wire to the negative (-) spade lug
of Battery 1. Connect the red with white stripe wire to the
positive (+) spade lug of Battery 2 and the black with white
stripe wire to the negative spade lug of Battery 2. No fault
indicator should be present. If faults are present, see the
Troubleshooting Guide Section 9.0. System check is now
complete.
NOTE: If new batteries with low terminal voltage are
used, the Low/No battery LED may activate and the
Trouble Sounder will sound. Silence the Trouble Sounder
and charge the batteries. The Low Battery indicator will
deactivate after the batteries are fully charged; no longer
than 48 hours.
Step 7. Check Field Wiring: Check the integrity of all
field wiring following directions defined in the Field Wiring
Checkout Procedures found in Section 4.2. This check
must be performed before connecting wiring to the system.
Be certain all external wiring is correct (no opens, shorts,
or grounds) and is terminated with the end-of-line devices
provided.
Step 8. Connection of Field Wiring: Remove power
from the system and connect the first circuit to the
control unit. Restore power and verify that the circuit is
working properly. If not, refer to Section 9, Trouble-
shooting Guide, for specific steps for isolating and
identifying the source of the problem. Repeat, connecting
the field wiring one circuit at a time, as shown on the
system wiring diagram created in Step 1. DO NOT MAKE
ALL CONNECTIONS AT ONCE! Connecting one circuit
at a time allows for the quick identification of wiring
errors and prevents the possibility of a wiring error
causing damage to the system electronics. During the
connection process document any changes made in the
system wiring on the system wiring diagram.
Step 9. Test System: An installation of a fire alarm
system is NOT complete until the acceptance testing and
system documentation is completed. Acceptance testing
involves the actuation of all of the initiating devices and
the verification that each device causes the appropriate
response. The acceptance testing also includes the
verification that each and every notification appliance is
operational and operates when intended. Each function
the system is intended to perform must be verified.
The documentation must include a completed Record of
Completion form (Figure 1-7.2.1 in NFPA 72-1996) and a
set of As-Built drawings that show exactly how the system
is actually wired and the serial numbers of all devices
used.
Refer to Section 6 and 7 of this manual for additional,
more detailed information.

The large push-buttons are primarily used to handle
alarm and trouble conditions in the system. The SYSTEM
RESET push-button is used to reset any zones that are in
an alarm condition. If the SYSTEM RESET push-button is
pressed and no alarm condition has occurred, the BMB
will perform a battery test within 15 seconds. This allows
the installer to test the batteries without waiting for the
standard battery test which is performed every hour. The
ALARM SILENCE push-button is used to silence any
audibles that have not been programmed as non-
silenceable. If an alarm condition occurs after the
audibles have been silenced, the audibles will sound
again. The TROUBLE SILENCE push-button will silence
all activated trouble conditions when pressed. If a trouble
condition occurs after the trouble has been silenced, the
local sounder will sound again. These three push-buttons
are also used in programming mode (see Section 5.2,
System Programming).
Located on the bottom of the Daughter Board is one small
push-button labeled PROG. This push-button is used
only for BMB function map programming (see Section 5.2,
System Programming).
BMB MAIN BOARD LED DESCRIPTION
The BMB main board has 10 yellow LEDs that are used to
indicate system troubles that are not zone related (see
Figure 5.6, LED Location Diagram for Programming
Location and Programmed Value). These LEDs are also
used for function map programming (see Chapter 5.0,
Programming).
NOTE: Not all system troubles are indicated on the 10
yellow LEDs located on the BMB main board. See
Figure 3.2d for a list of system troubles that are indi-
cated through the use of an ESL 2500 keypad.

Sentrol 1-800-547-2556Sentrol 1-800-547-2556
3.3 ZEM ADDRESS SELECTION
Many facilities need more than one initiating device circuit
in order to implement a design that complies with all of the
code requirements. Additional initiating device circuits (up
to 25 additional circuits before it is necessary to begin
networking multiple control panels) are added by adding
Zone Expander Modules (ZEMs) to the basic 2501 FACP.
When this is done the ZEM must be programmed with an
electronic “name” in order for the BMB computer to know
which ZEM is initiating the alarm signal. The first added
ZEM should be given address “1” by putting S1 in the ON
position and S2, S3 and S4 in the OFF position. The next
ZEM should be given the address “2”, with S1 through S4
being positioned OFF-ON-OFF-OFF, respectively. Figure
3.3 shows the addressing for the ZEMs.
ZEM NUMBER S1 S2 S3 S4
1 ON OFF OFF OFF
2 OFF ON OFF OFF
3 ON ON OFF OFF
4 OFF OFF ON OFF
5 ON OFF ON OFF
6 OFF ON ON OFF
When using multiple 2502 Class B zone expansion
modules, it will be necessary to leave some panel zones
unused to ensure that the modules LED’s line up with the
correct zone identifiers on the front panel display. For
example, if two 2502-ZEM’s are used, zones 2 and 3 will
be used, then 4 and 5 will be skipped, and zones 6 and 7
will be used for the second 2502-ZEM. Please call Sentrol
Technical Services at 1-800-800-2027 with any questions.
NOTE: For best zone LED alignment results, do not use
multiple two zone expansion modules (2502-ZEM) when
a four zone module (2504-ZEM) can be used.
Only the combinations listed above are allowed. Any
other combinations will not be recognized by the 2501
(FACP). If two (2) or more modules are set to the same
address, the 2501 (FACP) will not recognize the incor-
rectly addressed modules.

System Trouble Description
CPU Fault Indicates that the BMB microprocessor is de-
fective and the system is completely inactive.
BELL SILENCE Indicates that a bell (NAC) has been silenced.
BELL 1, BELL 2, BELL 3, Indicates that there is a short or open in the
wiring or that the EOL is missing.
GND FAULT Indicates an earth ground connection to the
system. (see Section 6.3,
Ground Fault Test
).
LOW NO AC Indicates the loss of AC power or that the AC
voltage is not high enough to power the
system.
LOW NO BATT Indicates that the battery voltage is low or
the batteries are missing. If the battery volt-
age drops far enough and there is no AC

Functional modules are added to the basic 2501 FACP by
snapping them onto the module mounting rails of the
system enclosure. The modules obtain power and
communicate via four conductor data bus cables installed
between the BMB and the first module, from the first
module to the second, etc., until all modules are con-
nected to the data bus. The assembly of the ESL 2501
Fire Alarm Control Panel is illustrated in Figures 3.0,
3.1b, 3.1c, 3.4, 3.10 and 3.11 in this manual. A zone
description card is supplied for each zone module, as
shown in Figure 3.12, to identify each zone in terms
relevant to the specific application.
The 2500 Keypad is installed where the owner/operator
needs system interface and access. Interconnection
between the FACP and the Keypad is by means of a four
(4) conductor cable. The connection between the ESL
2501 Fire Alarm Control Panel and the ESL 2500 Keypad is
illustrated in Figure 3.5b.
The 2500-RA and 2500-RADVR are installed where
required by local jurisdiction or when the owner/operator
needs remote system status and zone status. Intercon-
nection between the FACP and the remote annunciators
is by means of a four (4) conductor cable. The connec-
tion between the ESL2501 Fire Alarm Control Panel and
the remote annunciators is illustrated in Figure 3.5c.
The 2500-LEM/LRM is installed where a municipal system
is in place. Interconnection between the FACP and the
LEM/LRM module is by means of a five (5) conductor
cable. The connection between the ESL2501 Fire Alarm
Control Panel and the LEM/LRM is illustrated in Figure
3.5d.

4.1 DETAIL INSTALLATION GUIDE
The initiating device circuits and notification appliance
circuits of the ESL 2501 Fire Alarm Control Panel are
classified as power limited circuits. These circuits can be
installed using any of the methods permitted by Article
760 of the National Electrical Code (NEC), NFPA 70-1996,
for power limited fire alarm (PLFA) circuits. See 760-52
of NFPA 70-1996.
The following circuits are classified as non-power limited
fire alarm (NPLFA) circuits:
Wiring connected to “dry” TROUBLE relay contacts
Wiring connected to “dry” ALARM relay contacts
Wiring extending from the Digital Alarm Communica-
tor (DAC) to the telephone system
Wiring extending from “dry” Zone Relay contacts
Wiring extending from the 2500-RADVR output
connector
Figure 4.1a Power-Limited Routing with DAC
Non-power limited fire alarm system wiring may be
installed using any of the methods permitted by Article
760 of the National Electrical Code (NEC), NFPA 70-1996,
for non-power limited fire alarm (NPLFA) circuits. See
760-21to 760-31 of NFPA 70-1996.
The circuit conductors of a power limited fire alarm
circuits must be separated from non-power limited fire
alarm circuits and ordinary light and power circuits
pursuant to the requirements of Article 760-54 of the
NEC. Figures 4.1a and 4.1b show one method of routing
conductors that can be used to comply with the required
1/4 inch separations.

Verify wire sizes are adequate for all notification and
initiating circuits. The maximum allowable initiating
zone resistance is 30 Ohms. See Figure 4.1c below:
Many audible/visual notification appliances cannot
tolerate more than a 20% voltage drop from the specified
device voltages. See Figure 4.1d below to determine
maximum distance for wire gauge used.
Incoming AC voltage should be stable at a nominal
120 Volts. This is especially important in new
construction where incoming power may be high or
unstable with temporary connections often causing
large, inductive voltage spikes.
Ground the system properly. All of the voltage
transient suppression in the ESL 2501 Fire Alarm
Control Panel is referenced to earth ground. It is
important that the earth ground connection of the
FACP be of the lowest possible impedance and that
the possibility of voltage differences between the
FACP ground and that of the telephone and public
utility power systems be minimized. For this reason
the ideal ground for the fire alarm panel is the
“unified earth ground”. A unified earth ground bonds
together the ground rods for the power lines, tele-
phone, and fire alarm control panel. See Figure 4.1e.
This reduces the chance of step voltage blowout, a
problem that may occur during lightning strikes.
Refer to NEC Article 250 for proper grounding
requirements.
The ground connection to the ESL 2501 is made via
the green wire of the FACP power supply. Using a
Listed splice connector, secure a minimum 14 gauge
solid ground wire to the green wire, the earth ground
connection, on the control panel. Attach the earth
ground wire to a bonded earth ground. Be sure to
keep the wire runs short and avoid 90o or sharp
turns. Bends must have a minimum radius of eight
inches. The ground wires must be routed separately
and toward the earth. Always use eight-foot copper
clad ground rods. Never run parallel to metal without
properly bonding to that metal.
Run initiating device circuit wires separately. Most
supervised circuits use voltage or current sensing
initiating device methods that are very sensitive to
induced voltages on the wiring. Therefore, under no
circumstances run AC power, speaker, public
address, intercom, or switch control wiring with
inductive loads in the same conduit or the immediate
vicinity of the control wiring.
Do not overlook adequate lightning protection.
Lightning damage commonly occurs from four
sources:
1. Through alarm loop wiring
2. Through AC power inputs
3. Through telephone connections (if used)
4. Through earth ground or power ground connections.
The ESL 2501 uses state-of-the-art suppression tech-
niques to minimize the potential for damage due to
lightning via each of these routes. However, this does not
obviate the need to ensure that proper lightning suppres-
sion equipment has been installed at the point where both
the public utility power and telephone service enter the
building. Refer to Article 250 of the NEC for these
criteria.
There is no known protective device available which is
capable of protecting equipment from damage caused by
“direct hit” strikes of lightning due to extremely high
energy released (10 million to 100 million Volts @ 10,000
to 30,000 Amps).
The effects of the electro-magnetic pulse (EMP) from a
lightning strike can be minimized by avoiding running
wiring long distances across the ceiling or roof of a
building prone to lightning strike or along vertical
structural steel members expected to conduct lightning
currents. Lightning protection designed, installed and
maintained in accordance with the requirements of NFPA
77 will minimize the effects of a lightning strike on the
building structure as well as the fire alarm system.
Additional protection is suggested in areas subject to
above average lightning activity or induced voltage spikes
and fluctuations due to power line load switching.

4.3 ALARM INITIATING DEVICES
This section describes how to field wire initiating devices
such as smoke detectors, pull stations, heat detectors, and
waterflow alarm devices. Each zone may be programmed
individually; refer to Programming, Section 5.0. Refer to
Figures 4.0a & 4.0b for Class B (Style B) wiring.
4.3.1 TWO-WIRE SMOKE DETECTORS
NOTE:
Connect only two-wire smoke detectors UL
Listed as compatible to the 2501 (FACP). Refer
to Appendix A.
Two-wire detectors receive their power directly
from the zone terminals and transmit the alarm
signal through the same wires. Be certain to
observe polarity when installing detectors.
Up to twenty (20) detectors may be wired to
each zone. All initiating devices must be wired
correctly for proper supervision with an end-of-
line 2.7K 1/2W resistor (provided) installed
after the last device.
Wiring the ESL 521 Series two-wire detector
with automatic maintenance reporting is the
same as wiring standard two-wire detectors and
the CleanMe® signal is automatically monitored.
Up to twenty (20) ESL 521 Series smoke
detectors may be wired to each zone. Refer to
the documentation included with the ESL 521
Series detector for additional installation
instructions. Note that an ESL 505 module is
not required for the 2501 (FACP) zones.
See Figures 4.0a & 4.0b for Class B (Style B) connection
to the panel.
4.2 FIELD WIRING CHECKOUT
PROCEDURES
NOTE: MAKE SURE THAT AC AND BATTERY POWER
ARE DISCONNECTED BEFORE PROCEEDING.
1. Test all field wiring before connecting any equipment.
A. Insure no unwanted voltages are present on
circuit conductors and ground. They are a
hazard and may prevent proper system operation.
B. All wiring except those intentionally and
permanently grounded must be tested for
isolation from ground using an insulation testing
device such as a “Megger”.
NOTE: Caution must be exercised when using voltage
generating test instruments such as a “Megger”.
Damage to equipment could result if the equip-
ment is connected (wired) during wiring tests.
C. All wiring, other than those intentionally
connected together, must be tested for conduc-
tor-to-conductor isolation using an insulation
testing device.
2. With each circuit pair short-circuited at the end of
the circuit, measure circuit resistance with an
Ohmmeter.
3. Perform testing as described previously after any
addition, deletion, or mechanical or electrical
damage to the system has occurred.

Sentrol 1-800-547-2556Sentrol 1-800-547-2556
4.3.3 SPRINKLER SYSTEM WATERFLOW
AND SUPERVISORY DEVICES
NOTE: There are two important cautions that should be
observed. First, if the detectors being used are
equipped with integral Trouble (Fault) relay contacts
these contacts must be wired such that the first Trouble
(Fault) contact is beyond (further from the control
panel) the last Alarm contact in the circuit. Second, the
battery saver function drops the system operating power
supply to 12 volts, DC Be certain that the detectors
being used will operate at that potential. If the battery
saver function is switched off the switched auxiliary
power potential will remain at 24 volts.
Normally open contact type waterflow alarm devices may
be connected, along with conventional manual alarm
stations or heat detectors. All zones to which waterflow
alarm devices are connected must be programmed so that
the system alarm indicating devices cannot be silenced.
See Programming, Section 5.0.
Supervisory signals for status reporting of waterflow
control valves, supplies, etc. must be connected to a
separate zone, and programmed for supervisory status.
See Programming, Section 5.0.
4.5 ZONE EXPANSION MODULE (ZEM)
CONNECTION
The Zone Expansion Module (ZEM) allows for the
addition of up to 24 initiating device circuits when the
four circuit, Class B modules are used. Since there is one
initiating device circuit integral with the BMB, this results
in a total capacity of 25 initiating device circuits per ESL
2501 FACP. Refer to Figure 1.4, Custom Panel Building
Table for the available ZEM add-on configurations. The
ESL2501 Fire Alarm System enclosure can accommodate
three (3) ZEMs. When the 2501 is configured with
additional ZEMs they are housed in an additional
enclosure, part number 2500-SH.
4.5.1 ESL 2502-ZEM AND ESL 2504-ZEM
The ESL 2502-ZEM is a two zone Class B expander
module and the ESL 2504-ZEM is a four zone Class B
expander module. Refer to Section 3.5, Installing the
ZEM, BMB, and DAC for correct installation of the ZEM
card. Connect the left most databus connector on the
ZEM to the databus connector on the BMB or to the right
most databus connector on a previously installed ZEM
using the provided six inch 4 pin to 4 pin cable assembly.
Assure that all unused zones are terminated with a 2.7K
5% end-of-line resistor (provided). See Figures 4.0a &
4.0b for Class B (Style B) wiring. For zone type selection
see System Programming, Section 5.2.
When using multiple 2502 Class B zone expansion
modules, it will be necessary to leave some panel zones
unused to ensure that the modules LED’s line up with the
correct zone identifiers on the front panel display. For
example, if two 2502-ZEM’s are used, zones 2 and 3 will
be used, then 4 and 5 will be skipped, and zones 6 and 7
will be used for the second 2502-ZEM. Please call Sentrol
Technical Services at 1-800-800-2027 with any questions.
NOTE: For best zone LED alignment results, do not use
multiple two zone expansion modules (2502-ZEM) when
a four zone module (2504-ZEM) can be used.
4.4 ALARM NOTIFICATION APPLI-
ANCES
Use only polarized UL Listed compatible notification
appliances rated for 24 VDC (see list of devices in
Appendix A). See Figures 4.0a & 4.0b for Class B (Style
Y) connection to the panel.
The BMB provides two notification appliance circuits that
may be expanded to four (two additional) with the
ESL2500-BELL. Refer to Figure 4.0a for wiring indicating
devices to the BMB.
NOTE: Maximum notification current is 1.5 Amps per no-
tification appliance circuit; TOTAL OPERATING CUR-
RENT CANNOT EXCEED 6.0 AMPS. Choose the correct
wire size so that the maximum voltage drop of 2 VDC at
furthest device on circuit is not exceeded. (see Figure 4.1c).

4.7 CONNECTION TO SUPERVISING
STATION FIRE ALARM SYSTEMS
The ESL 2501 FACP is designed to permit transmission of
fire alarm signals from the protected premises to a
Supervising Station Fire Alarm Panel at a Central Station
or Remote Supervising Station by means of an add-on
module that utilizes Digital Alarm Communicator (DAC)
technology, the 2500-DAC.
4.7.1 CONNECTING THE 2500-DAC
The 2500-DAC, Digital Alarm Communicator, is installed
in a dedicated location, adjacent to the BMB of the ESL
2501 Fire Alarm Control Panel. It provides for the
connection of both the primary and stand-by telephone
lines via the standard telco connectors. Figure 4.7.1
illustrates the wiring required to provide signaling to a
Supervising Station Fire Alarm System from a single ESL
2501 FACP.
4.6 SUPPLEMENTARY CONTACTS
CONNECTION
This section describes how to wire Supplementary Alarm
and Trouble Contacts and the optional Zone Relay Modules.
NOTE: Supplementary Alarm and Trouble Contacts are
for power-limited applications only. (See Section 4.1,
Installation Recommendations/Precautions).
4.6.1 SUPPLEMENTARY ALARM CONTACTS
Dry, Form “C” contacts are provided for controlling
supplementary alarm functions from the BMB. Contacts
are rated 2A @ 30 VDC resistive. The terminals are
Common Alarm NC, COM, and NO. Contacts transfer in
alarm.
4.6.2 SUPPLEMENTARY TROUBLE CONTACTS
Dry, Form “C” contacts are provided for controlling
supplementary trouble (fault) functions from the BMB.
Contacts are rated 2A @ 30 VDC resistive. The terminals
are Common Trouble NC, COM, and NO. The trouble
relay is normally energized and will de-energize if AC
and/or battery power or any other system trouble occurs.
For use with door holders, the supplementary trouble
contacts are programmable for transfer on loss of AC
only. Additionally, if the system is programmed for use
with a 2500-DAC, the contacts are automatically pro-
grammed so that they will not transfer on loss of AC only.
The batteries must also be low. This provides the required
delayed reporting at loss of AC. See Section 5.0 Program-
ming.
4.6.3 ZONE RELAY MODULE (ZRM)
(OPTIONAL)
The Zone Relay Module (ZRM) is a zone follower and each
relay follows its corresponding zone on a Zone Expansion
Module (ZEM). Zone 1 on the BMB does not have a
corresponding Zone Relay Module and will only trigger
the Common Alarm relay. The ZRM’s plug directly into
the ZEM’s and only require wiring the terminals labeled
NO, COM, and NC. Each relay has dry, Form “C”
contacts rated 2A @ 30 VDC resistive.
NOTE: Circuits connected to a ZRM must be power-limited.

5.1 INTRODUCTION
PROGRAMMING
At the heart of the ESL 2501 Fire Alarm Control Panel is
a microcomputer that controls all system functions and
the response of the system to incoming signals. A portion
of the microcomputer program is a function map that
serves two purposes. First it tells the microcomputer
what types of modules are installed, ensuring the correct
response when a signal is generated by a given module.
Second, it controls how the system will respond to a given
in-coming signal condition. Items that can be pro-
grammed are: types of zone inputs, bell-zone associations,
bell cadence definitions, battery saver mode, AC fre-
quency (60Hz or 50Hz), zone expanders installed,
communicator type, number of supervised keypads,
keypad ability to silence the panel, time of day, communi-
cator information, zone names, and passcodes.
The programming buttons and indicators allow the
installer to modify the most commonly used items in the
function map. A keypad allows modification of all items
in the function map (with the appropriate passcode. See
the keypad manual for more details). Section 5.6,
Programming Matrix indicates which items are only
programmable from the keypad.
When programming the function map from the panel, flip
the daughter board’s overlay over to facilitate program-
ming (see Figure 5.1b). All button and LED references in
the programming sections refer to the ON-BOARD
PROGRAMMING INTERFACE side of the overlay. Also,
install the PROGRAMMING LOCATION LEDS guide on
the Basic Master Board (BMB).
5.2 SYSTEM PROGRAMMING
The Basic Master Board (BMB) automatically recognizes
when a Zone Expander Module (ZEM) is added to the
panel and programs the module automatically based upon
the module’s address. If two or more modules are set to
the same address, the 2501 (FACP) will indicate trouble
communicating with the modules and will not be able to
indicate alarms or troubles correctly. Likewise, if a ZEM
module is removed without changing the function map to
inform the panel that it is not installed, the panel will
indicate trouble communicating with the module.
To program the panel using the Basic Master Board
(BMB):
1. Flip the daughter board’s overlay over so it displays the
side marked ON-BOARD PROGRAMMING INTER-
FACE. Install the PROGRAMMING LOCATION LEDS
overlay on the Basic Master Board (BMB). If desired,
place the location LED overlay on the LEDs.
2. Push and hold the PROG button until the LOC LED
begins flashing (approximately 5 seconds). When the
system goes into programming mode, it displays
Location 1 and the current value.

5.1.1 PROGRAMMING INDICATORS
The 2501 (FACP) has 16 LEDs that are used for displaying
the system status. Of these, 13 are used for displaying
information while in the front panel programming mode.
The Location (LOC) green LED (located on the daughter
board) starts flashing when the programming mode is
entered. It is used to indicate that the UP/DOWN buttons
will affect the programming location number. The VALUE
red LED (located on the daughter board) flashes to
indicate that the UP/DOWN buttons affect the location’s
value. The 1 and 2 red LEDs, 4 and 8 yellow LEDs
(located on the daughter board) display the programmed
value of the current location in the programming mode.
The 64, 32, 16, 8, 4, 2, and 1 yellow LEDs (located on the
BMB in the lower right-hand corner) display the current
programming location in the programming mode. A
location LED overlay is included in the accessories
envelope included with each panel.
5.1.2 PROGRAMMING BUTTONS
The Basic Master Board (BMB) has 1 push-button (PROG)
to activate and terminate the system programming mode,
1 push-button (LOC/VAL) to switch between location and
value, and 2 push-buttons (UP, DOWN) to increment or
decrement the location/value (see Figure 5.1a).

EXAMPLE: To set the date to October 9, 1997 and the
time to 5:35 pm
The time and date are programmed through Basic Master
Board programming. The date format must be entered as
m/dd/yyyy. The time must be set in military time format,
24:00 hours. (See programming example below.)
5.3 TIME & DATE PROGRAMMING
See Section 5.6, Programming Matrix for the time and
date programming locations and default values.

For example, the month is contained at location 80. The
location is indicated by the LEDs that are lit from the
table above, 64 + 16 = 80. The value is indicated by the
LEDs that are lit; 8 + 2 = 10 or October.
NOTE: If an invalid date is entered, the 2501 (FACP)
changes the incorrect value to the closest valid value
before saving changes. There is no visible or audible
indication given if an incorrect value is entered during
time and date programming.
Figure 5.3 Time & Date Programming Example
3. Press the LOC/VAL button to switch between
location and value. When the LOC LED is flashing,
pressing the UP or DOWN buttons will increment or
decrement the location displayed. When the VALUE
LED is flashing, pressing the UP or DOWN buttons
will increment or decrement the value of the selected
location. (See Section 5.6, Programming Matrix, for
programmable values of each location). By pushing
and holding the UP or DOWN button, you may
quickly scroll through the location/value numbers.
4. To exit out of programming mode, press and hold the
PROG button until the LOC or VALUE LEDs stop
flashing (approximately 5 seconds).
5. To save any value changes made, move to a new
location. The changes to the current location is not
saved if the system times out (10 minutes without a
button press) or if programming mode is exited by
using the PROG button. All changes made to other
locations are saved, only the current location
changes are not saved.
The Panel automatically exits out of programming mode if
no activity occurs for 10 minutes. If an alarm occurs
during programming, the panel automatically exits out of
programming.
To program the function map with a keypad, see the ESL
2500 Keypad Instruction Manual 64812808.
See Section 5.6, Programming Matrix for the program-
ming locations and default values.
NOTE: While in the programming mode, all other
indicating devices will operate as normal. If a zone goes
into alarm while you are in the programming mode, the
alarm sounds and the panel automatically exits out of
programming mode.

5.4 BATTERY SAVER PROGRAMMING
5.5 CLEANME® MODE PROGRAMMING
The 2501 (FACP) supports a unique feature implemented
by the ESL 521 series Two-Wire CleanMe® Smoke
Detector. This feature allows the control panel to receive
a signal from the 521 series detector, notifying the
control panel that the detector has drifted outside of its
UL Listed sensitivity range or has a hardware fault
problem. The CleanMe® signal enables the installer to
receive a warning signal at the panel and the Supervising
Station if the system is monitored. This gives the
installer time to clean the detector by replacing the
optical chamber with a new one thereby reducing
unwarranted alarms. There is no action required to
implement this feature. The control panel automatically
recognizes the signal if present and will turn on the
detector maintenance LED and annunciate a system
trouble. If a DAC is present, the Supervising Station, if
monitored, will be notified.
The 2501 (FACP) implements a programmable feature
called the battery saver mode. The purpose of this mode
is to allow the panel to utilize smaller, less expensive
batteries while still meeting standby requirements. This
mode is selected by programming the panel for battery
saver mode (see Section 5.2 System Programming and
Section 5.6 Programming Matrix). After selection of this
feature the operation is completely transparent to the user.
The operation of the panel when battery saver mode is
selected is as follows. The panel will automatically switch
the batteries into parallel upon loss of AC or a low AC
condition. The connection of these batteries in parallel
effectively doubles the standby capacity of the batteries.
The batteries will remain in this condition until AC is
restored or the level is sufficient to restore normal
operation.
While the panel is in standby on the secondary source
(batteries in parallel), the panel continues to operate
normally. If an alarm occurs, the panel automatically
switches the batteries back to a series configuration. This
provides the 24 VDC alarm voltage for the indicating
(NACs).
NOTE: The AUX 12/24 and SWITCHED AUX 12/24 are
always 12 VDC if battery saver mode is selected and 24
VDC if battery saver mode is not selected. The proper
battery calculations must be performed based on the bat-
tery saver mode selection (see Appendix B). ESL manu-
factures a complete line of 12V devices including 12V door
holders and smoke detectors.

5.7 FUNCTION MAP DESCRIPTION
Zone Definition - This defines what type of devices are
connected to a zone and how the zone will respond when
one or more of the devices signals an alarm condition.
Zone Bell Association - This associates a NAC or group of
NACs to be activated when the specified zone is in alarm.
Notification Appliance Circuit Definition - Defines the
cadence a NAC will use when activated. Setting the
cadence to Not Used will also deactivate supervision of
the NAC.
Battery Saver Mode - If set to On, the batteries will be
put into parallel mode to conserve power. This only
happens when AC has failed and no NACs are active.
AC Cycles - Specifies the frequency of the supplied AC
power to be used for time-keeping.
Zone Expander Module Definition - Specifies if a zone
expander is installed.
Communicator Type - Specifies the type of communica-
tor installed.
5.7.1 ZRM OVERRIDE
Normally, the relays on a ZRM are configured as alarm
followers for the corresponding zones on the ZEM that the
ZRM is installed. Programming zones to override a ZRM’s
relays allows the installer to program the BMB to have a
more sophisticated relay control rather than wiring
numerous relays in parallel or serial. If no zones are
programmed to override a particular ZRM relay, that relay
will act as a zone follower for its associated zone. The
BMB can trip multiple relays based on one zone input
(relays 1, 6, 22 can activate when zone 1 goes into alarm
by setting location 122 to 1, location 123 to 2, and
location 127 to 2). The BMB can also have multiple zones
trip the same relay (zones 3, 12, 25 can activate relay 3
when any of the three go into alarm by setting location
134 to 4, location 188 to 4, and location 266 to 4). The
BMB can also be programmed for a combination of both
(zones 1, 2, 3 can activate relay 1, 3 and zones 4, 5, 6 can
activate relay 6, 7 by setting location 122 to 5, location
128 to 5, location 134 to 5, location 140 to 6, location 146
to 6, and location 152 to 6). One use for this ability is to
have all fire zones activate relay 1 and all supervisory
zones activate relay 6. All fire zones would have their
associated ZRM override for ZRM 1 set to the value 1. All
supervisory zones would have their associated ZRM
override for ZRM 2 set to the value 2.

INITIAL ACCEPTANCE TESTING
SETUP
1. Connect the control to a primary power source (110
to 120 VAC).
2. Connect the Zone One (Alarm initiating) input to
Normally Open switches or Sensors. This connection
must be in parallel to the 2.7k Ohm 5% end-of-line
(EOL) resistor (provided). (Trouble with the circuit
may occur if the resistor is connected in series).
3. Connect the EOL, 2.7k Ohm 5% resistor (provided),
to each of the Bell circuits. A Trouble Indication will
occur if the EOL is not connected.
4. Connect (observe polarity) an audible device into
BELL 1 & BELL 2 terminals. This connection is in
parallel to the EOL .
5. Connect the 4-wire bus connector between the BMB
and each ZEM that is to be coupled into the system.
6. Each ZEM must have an EOL, 2.7k Ohm 5% resistor
(provided), for each zone connected in order to
prevent a trouble condition.
7. Connect the batteries, minimum of two 12 Volt 7 Ah
sealed lead acid batteries. Failure to connect a
battery will result in a trouble condition.
TESTING AND SYSTEM RESPONSE
6.1 ALARM ZONE TESTING
Visually observe the LEDs located on the Basic Master
Board (BMB) to verify that no troubles, alarms, or
supervisory conditions exist. If a condition is detected,
check the zone LEDs to identify if the problem is zone or
system related. Correct the problem and then press the
SYSTEM RESET button to reset the panel and clear the
condition.
Following the installation of all of the system components
and the programming of the FACP, a complete, 100%
acceptance test must be performed and the results
documented. A permanent record of the initial accep-
tance tests must be made and retained with the system
documentation. Refer to Chapter 7 of NFPA 72-1996, the
National Fire Alarm Code.
Upon the completion of the Initial Acceptance Test,
restore all circuits and system components to their
design condition. Install the 2501 FACP Operating
Instructions, Appendix C, in an easily accessible and
readable location adjacent to the FACP. Advise the
owner/operator of the site and the monitoring firm that
the system is now “on-line”.
If an alarm condition occurs and the sounder is on, either
the SYSTEM RESET or the ALARM SILENCE push-button
may be pressed. If the SYSTEM RESET push-button is
pressed first, the local sounder will deactivate, the bells
will silence and the system LEDs will extinguish. All zones
in alarm will be reset. If the ALARM SILENCE push-
button is pressed first, the proper system and zone LEDs
and the trouble sounder will become active. If the
SYSTEM RESET push-button is pressed after the alarm is
silenced, the zone(s) that went into alarm will be reset.
NOTE: The 2501 (FACP) uses three (3) different types
of tones to distinguish between an alarm, a trouble, and
a supervisory trouble. The output tones for the Sounder
will be as follows:
Alarm tone will have a steady tone
Trouble tone will have a pulsing tone
Supervisory tone will have a rapid pulsing tone

6.2 NOTIFICATION APPLIANCE CIR-
CUIT TESTING
There are two (2) Notification Appliance Circuits (NACs)
for audible and visible notification appliances integral on
the BMB. Consistent with the new requirements of the
National Fire Alarm Code - 1996 the default setting for
the BELL 1 / BELL 2 circuit is the Temporal 3 Code 3
(ANSI S3.41, Standard Emergency Evacuation Signal).
The BELL 3 / BELL 4 circuit default setting is “not used”.
If visible notification appliances are needed for ADA
compliance they can be connected to this circuit once it
has been reprogrammed for either steady or non-
silencable operation. Other signal options are available, as
required by 3-7.1(b) of NFPA 72-1996, for when the
planned action in response to a fire emergency is not
evacuation but relocation, or where the Authority Having
Jurisdiction requires some other signal.

7.1 MAINTENANCE
The 2501 (FACP) is relatively maintenance free, other than
performing regular testing to make sure all the systems are
operating properly. Batteries require special attention.
7.1.1 BATTERIES
The 2501 (FACP) uses two sealed lead-acid batteries as the
secondary power source. The batteries must be replaced if the
Low Battery LED remains on for more than 48 hours (meaning
one or more of the battery cells are dead or the batteries will
not hold a charge). If the batteries are dead, they must be
replaced with batteries of the same voltage and capacity rating,
with a maximum of 12 V, 17.2 Ah. Assure that any battery
used allows a minimum clearance of 1/4" from its terminals to
any non-power-limited circuit, including the system cabinet.
7.0
INSPECTION AND TESTING
No piece of equipment can be expected to operate reliably
without regular maintenance. The ESL 2501 Fire Alarm
Control Panel is designed to provide years of reliable perfor-
mance. Nevertheless, like all other building systems it must be
maintained properly. The appropriate inspection and testing
requirements differ depending upon whether the 2501 FACP is
being used for household fire warning or in a commercial,
architectural, institutional or non-household residential
application. Household fire warning systems are inspected and
tested in accordance with NFPA 72-1996, Chapter 2 (see
Section 10). All other systems are inspected and tested in
accordance with NFPA 72-1996, Chapter 7.
Inspect and test the fire alarm system in accordance with the
inspection and test procedures and schedules established by
the local AHJ or presented in Chapter 7 NFPA 72-1996. Prior
to commencing the inspection and test of a fire alarm system
make certain that:
The owner/operator has advised the facility occupants and
that a fire watch has been established
The public fire service has been notified
The off-premises supervising station fire alarm system
operator has been advised and that an alternate means for
reporting a fire has been established
Document all inspection and testing. Some fire alarm system
components do not have to be tested at each scheduled
inspection. Keep track of which devices are tested to ensure
that different devices are tested at the subsequent inspection.
Subsequent to the completion of the inspection and testing of
the system make certain that the occupant, public fire service
and supervising station fire alarm system operator are advised
that the system has been placed back “on-line” and to treat all
subsequent alarms as indications of a fire in progress.

HOUSEHOLD FIRE WARNING
SYSTEMS
10.1 INSTALLATION
This system should be installed in accordance with
Chapter 2 of the National Fire Alarm Code 72-1996. A
copy of this Standard may be purchased from the
National Fire Protection Association, Batterymarch Park,
Quincy, MA 02269
10.2 DETECTOR LOCATION
The minimum level of protection requires one smoke
detector between each bedroom area and the rest of the
house and on each additional story, including the base-
ment but excluding any crawl spaces and unfinished
attics. In new construction, a smoke detector also shall
be installed in each sleeping room. Detectors should be
located at the top of each stairway leading to an occu-
pied area.
In addition, it is recommended that heat or smoke
detection be located in the following areas if they are
separated by a door from the areas protected by the
required smoke detectors: living room, dining room,
attic, utility room, basement, furnace room, garage, and
hallways.
10.3 NOTIFICATION APPLIANCE
LOCATION
If smoke detectors have been used that do not contain an
integral signaling device with a minimum output of 85
dBA at 10 feet, a separate notification appliance must be
installed adjacent to each sleeping area. In new construc-
tion, where a smoke detector is also required in each
sleeping room, all detectors must be arranged so that the
signaling devices in all detectors operate whenever any
single smoke detector unit is activated.
In addition, it is recommended that additional signaling
devices be installed on each level and on the outside of
the premises. Check local codes before installing an
outside device to assure they are permitted or if a timed
cutoff is required.
1. Have at least two (2) possible escape routes from
each room of the house.
2. Before opening any door check for heat or smoke.
NEVER OPEN A DOOR THAT IS HOT TO THE
TOUCH.
3. If there is no alternative escape path available and
there is smoke in you escape path, crawl with your
head as close to the floor as possible. You can use a
wet cloth over your mouth and nose to reduce the
amount of smoke you inhale as you escape.
4. Have a prearranged meeting place outside the house.
5. Call the FIRE DEPARTMENT from outside the house
as soon as possible.
6. NEVER re-enter a burning building.
7. Practice your escape plan and meeting place with
ALL family members.
A properly designed household fire warning system,
implemented with the ESL 2501 Fire Alarm Control
Panel, is intended to provide enhanced life-safety for the
occupants in the event of a fire. It is intended to provide
a warning sufficiently early in the development of a fire to
enable the occupants to escape before conditions become
life-threatening. Once the warning has been provided the
occupants must still escape. Consequently, in order to
derive the intended benefit from the household fire
warning system, the household must have a pre-arranged
fire escape plan. A fire escape plan includes at least two
escape routes from all sleeping areas as well as a pre-
planned meeting place outside the building. The intent of
this system is not to preserve property but to facilitate
timely escape of the occupants.
Since it takes precious time for smoke to travel from a fire
to a smoke detector, the highest level of life safety is
attained when a smoke detector is installed in each room.
If fewer detectors are used the smoke must travel further
before encountering a smoke detector. A fire warning
system with fewer detectors responds more slowly,
allowing the fire to grow larger before the occupants are
warned of its existence. This translates to substantially
lower levels of life-safety.
10.4 ESCAPE PLAN
All automatic systems need regular maintenance in order
to provide continued performance and the Household Fire
Warning System needs regular maintenance as well. The
head of the household should test the fire warning system
at least monthly to verify that it is in working order. If
the system is monitored by an off-premises monitoring
firm, it is important to call the monitoring company
before the test of the system to ensure that the test is not
misconstrued to be a fire alarm. It is also necessary to
call the monitoring firm after the test to ensure that
alarms are not misconstrued to be tests. Any deviation
from “normal working” noticed by the building occupants
should be quickly corrected by a qualified, professional

The following steps should be used to determine the
correct battery capacities for your system.
1. First you must determine the exact configuration of
your system from the as built drawings generated
during the installation process.
2. Determine the number of notification appliances and
the standby current for each notification appliance
on each notification appliance circuit. Complete the
appropriate entries on the worksheet.
3. Determine the number of devices and the standby
current for each device attached to the Auxiliary
power terminals on the Basic Master Board. Com-
plete the appropriate entries on the worksheet.
4. From the as built drawings, determine the number of
each type of expansion module (Zone Expander
Module, Relay Follower Module, Bell Expander
Module, Printer Interface Module, Keypad and
Remote Annuciator) on the system and complete the
appropriate entries on the worksheet.
5. Total the rows across the worksheet and total the
Total Standby Current and Total Alarm Current
columns to arrive at the Total Standby Current
Requirements and Total Alarm Current Require-
ments for your system.
6. Transfer the Total Standby Current Requirements to
the TOTAL STANDBY CURRENT entry and perform

the indicated mathematical operation. This provides
you with the Standby Amp-hours your system
requires. The REQUIRED # OF HOURS IN STANDBY
varies by locale. Check with the proper Authority
Having Jurisdiction to determine your requirements.
7. Transfer the Total Alarm Current Requirements to
the TOTAL ALARM CURRENT entry and perform the
indicated mathematical operation. This provides you
with the Alarm Amp-hours your system requires.
The REQUIRED # OF MINUTES IN ALARM varies by
locale. Check with the proper Authority Having
Jurisdiction to determine your requirements.
8. Carry the calculated values to the proper entries to
arrive at the Minimum Battery Power Required for
your system.
9. Due to the natural aging effects on batteries due to
time, temperature, cycles and the level of discharge
during cycles, a de-rating factor is applied to help
predict the battery capacity more closely. Please
consult the appropriate manufacturer data sheets for
the appropriate de-rating factor to apply and then
perform the indicated mathematical operation. The
final result is the Total Standby Battery Capacity
required.
NOTE: This system always requires two batteries. The
calculations performed indicate the Amp-Hour rating
that each battery must carry. Do not mix batteries of
different capacities.

installed or the system configuration must be adjusted to meet the battery power requirements.

Standby Battery Power Required. If the answer exceeds the battery size you have chosen, then appropriate batteries must be
installed or the system configuration must be adjusted to meet the battery power requirements.
In this example, the two 7 Ah batteries in Normal Mode would not be sufficient to meet the 24 hour standby based on the
283 mA of continuous standby current required. However, if Battery Saver Mode is used, two 7 Ah batteries are sufficient. If
the Battery Saver Mode is used, the power supervision relays must be rated for 12 VDC operation. This results from the
decision to use Battery Saver Mode. Battery Saver Mode selects the Auxiliary terminals to be 12 VDC output instead of 24
VDC output.
