SAFECOM Telemetry Communications System
SAFECOM is a long-range telemetry communications system for monitoring life safety security alarm panels
which are remotely located at a customer site. The SAFECOM system utilizes specially designed telemetry
transmitters and receivers to provide a secure and reliable radio communications link between remote alarm
panels and a Central Monitoring Station. The information provided to the Central Monitoring Station allows
security personnel or local authorities to respond immediately and appropriately to all alarm events detected at
the customer site (see the following figure).

SAFECOM Communications Paths
The SC9000 Receiver acts as the nerve center of the SAFECOM Base Station. The SC9000 Receiver uses a
personal computer to operate the ST1000 Receiver Software and provide radio communications with Radio
Communicators via the RF2000 Radio Modem.
A Radio Communicator is a SAFECOM Communications Panel which is located at a customer site; commercial
or residential. The SC9000 SAFECOM computer can supervise, monitor and control up to 2,500 Radio
Communicators through two-way telemetry radio communications. The receipt of each message or poll that is
transmitted is validated by the receiving site; SC9000 computer or Radio Communicator. The receiving site will
then transmit an acknowledge message in response.
Supervisory polling is performed by the SC9000 computer for each Radio Communicators to verify two-way
telemetry radio communications and the operational condition of the Radio Communicator. The supervisory
polling interval is individually programmable for each Radio Communicator in the SC9000 computer account
base.
The SAFECOM radios can be configured to transmit (TX) and receive (RX) on a single frequency pair directly to
the Central Station. When the SAFECOM system is set up for Direct Mode, the SC9000 computer communicates
directly with the Radio Communicators in the field. No repeater is used for this type of SAFECOM system
(usually found in smaller proprietary systems like those found on a military base, university, or
factory/commercial plant.

The SAFECOM radios can also be configured to transmit and receive on a frequency pair to a repeater located
on a mountain, tower, or high building in the desired coverage area. When the SAFECOM system is setup for
Repeater Mode, the SC9000 computer communicates with the Radio Communicators through a, U.L. Listed,
SAFECOM SC801 or SC802 Data Repeater or a commercial grade voice repeater that has been configured with
a SAFECOM DP1000PWA controller board. The SC801/SC802 or equivalent repeater is normally installed at a
Commercial Repeater Site.

SC4000
Introduction
The use of a SAFECOM type repeater or equivalent, significantly increases the coverage area (range). Radio
area coverage and reception ranges are also dependent on the extent of a number of environmental effects, e.g.,
propagation losses due to atmospheric conditions, and the proximity of the radio transmission and reception
paths to dense foliage and metal structures, etc.
The majority of SAFECOM Radio Communicators are ordered to TX and RX in the 450-470 MHz UHF frequency
range. Other frequency bands currently supported by Radionics include, the 403-450 MHz, 470-512 MHz, 136174 MHz VHF range and the 900 MHz band. Additional frequency ranges are available upon request. The
SC9000 computer can communicate with all Radio Communicators assigned to that specific SAFECOM network
on a single RF “channel” through one SAFECOM RF2000 Radio Modem. A single RF “channel” is one radio
frequency pair for either direct OR repeater communications.
With the installation of a SAFECOM 4 or 8 port Expander Board, the SC9000 computer can communicate on 1 to
8 independent and addressable RF “channels.” Each RF “channel” communicates through a separate RF2000
Radio Modem. The addition of RF channels can be used to achieve backup redundancy in an area, or greater
RF coverage range.
The SAFECOM IT1500 Installation Tester allows the installer to test for a standardized signal level from the
remote radio site to the SC9000 computer and back, full two-way. Through this testing by a sales or service
representative a two-way communications link can be confirmed between a Radio Communicator and the
Central Station Receiver prior to the installation of a SAFECOM system.

SC4000, Full Data Transfer, Eight Zones, Four Outputs Radio Communicator
The primary SAFECOM Radio Communicator system is the SC4000. All other SAFECOM Radio Communicator
units are derived from capabilities and features found on the SC4000. The SC4000 is normally configured as a
stand-alone device for interface with the remote site’s existing alarm panel.

SC4000
Introduction
Each SC4000 is capable of monitoring contact open/closure status for four inputs. These input lines allow EndOf-Line (EOL) Supervisory Loop status monitoring for normal, open and short conditions. Up to four (4) Loops
may be monitored by the SC4000 as a UL Listed device. Up to eight auxiliary loops, two per Input, may be
monitored when the SC4000 is programmed for expanded mode as a non-UL Listed device. Any change of input
status condition, is immediately reported to the SC9000 computer. The SC4000 box tamper switch is also
continuously monitored for fault and restoral detection. A message is immediately sent to the SC9000 computer
when the SC4000 panel door is opened and again when it is returned to the closed position.
Each SC4000 is also configured with four two-position contact relay outputs. These relays may be selectively
configured for a Normally Opened (N.O.) or a Normally Closed (N.C.) condition. The Central Station operator can
remotely control the On/Off status of any device by sending radio commands from the SC9000 computer to
enable or disable the output relays. The SC4000 may also be programmed to automatically enable or disable the
output relays in response to a (Open or Short) detected on one of it’s Inputs or a SC4000 system failure
condition.
The SC4000 is normally configured as a stand-alone device for interface with the customer's existing alarm
panel. It is located at a customer site; commercial or residential. It is usually mounted on the wall, next to the
existing alarm panel. The antenna can be mounted directly on the SC4000 enclosure or remotely positioned for
optimum radio reception and transmission.
The SC4000 is normally installed to Intercept all of the alarm panel signals from the host alarm panel, also
known as a Dialer. The Dialer message is then digitally encoded and sent to the Central Station SAFECOM
SC9000 computer via the SAFECOM network. When SAFECOM is installed, it is the PRIMARY means of alarm
panel communication, with the phone line being the backup route. The SC4000 is capable of interfacing with
most alarm panels that use any industry standard pulse format (3+1, 4+2, FBI Superfast, Radionics Slow, etc.) or
Dual Tone Multiple Frequency, DTMF (ADEMCO Contact ID, ADEMCO High Speed, or ADEMCO 4+2 Express),
or SIA-R, or Radionics Modem and Modem IIe, or BFSK formats.
The SC4000 can almost be thought of as “a digital receiver in a box”, in that it has the ability to receive signals
from the host alarm panel and then generate an ACK and kissoff to the alarm panel, while sending the signal to
the Central Station SC9000 computer. The SC4000 sends all the necessary (ACK) tones to the host alarm panel
in response to the Dialer seizing the phone line. These ACK tones can be programmed through the Central
Station SAFECOM computer to Short and Long durations, frequencies of 1400 or 2300 Hz, as well as Low/High
(Contact ID) and the Radionics D6500 Modem ACK.
In addition, the SC4000 can be programmed at the Central Station to send a 440 Hz tone to the Dialer to
simulate dial tone. This tone comes in two bursts, lasting one second each, and is usually enough to satisfy
alarm panels that “sniff” the phone line.
The host alarm panel’s signals are sent to the Central Station SC9000 computer. Then the signals are displayed
on the SC9000 computer and transferred to the Central Station's Automation Software (BOLD, SIS, SIMS, DICE,
MAS, or most industry standard software packages). Primary routing of the digital alarm messages is via the
SAFECOM network between a SC4000 in the field and the Central Station SC9000 Receiver; then to an
Automation software program.
The SAFECOM SC9000 computer can monitor each of the unique alarm panel signals from each SC4000. The
SC4000 functions strictly in a supervisory capacity when interfaced with an existing alarm system. The SC4000
is an intercept/delivery system which is designed for easy installation and interface with almost any alarm
system; just connect the alarm panel Dialer cable to the SC4000 terminal strip and the House Phone cable, from
the RJ31X jack, to the SC4000 terminal strip. Refer to the wiring diagram for the SC4000, found in this manual or
on the SC4000 label, inside the door.
No modifications to the existing alarm system are required. The normal operation of the existing alarm panel and
security system is not affected in any way. The existing detectors and initiating circuits still report the status of
items directly to the host alarm panel. The difference is that when the host alarm panel goes to send a signal, it
no longer uses the phone line. The SAFECOM network is used to send all signals. One advantage to this is that
signals will continue to be received at the Central Station regardless of the phone line’s status and the house
phones will seldom be interrupted by the alarm panel.
The SC4000 requires 120VAC. This power source is usually connected to the SC4000 using the factory provided
wall plug-in power transformer.
The SC4000 is usually installed with a 12VDC battery for back-up power in the event of an AC failure. This
battery provides all of the necessary peak current (amperes) requirements when the SAFECOM Radio
Transceiver is transmitting (TX) and receiving (RX). The battery is mounted inside of the SC4000 Radio
Communicator enclosure and is accessible by opening the main door.
Each SC4000 is configured with a Fallback life safety feature. The Fallback mode of SAFECOM communications
ensures that all alarm event messages sent by the host alarm panel will be routed to the Central Station in case

Introduction
of a SC4000 or SAFECOM network failure. It also provides the ability to perform alarm panel programming and
downloading via the telephone line.
Alarm panel signals are normally routed to the Central Station by SAFECOM radio communications as the
primary mode of transportation. In the event that the SC4000 cannot send the Dialer message via the SAFECOM
network due to some type of failure, the message is automatically routed to the backup phone line and on to a
digital receiver at the Central Monitoring Station (Fallback Mode).

UL365 - Police Station Connected - Mercantile Premises
The following criteria must be met when installing the SC4000 to an alarm panel for an Underwriters Laboratories
Listed (UL365) Police Station Connected - Mercantile Premises "AA" Burglary Application:
• The alarm panel must be a UL365 Listed device for Police Station Connected -Mercantile Premises, and
must be suitable for this type of application.
• The alarm panel must be enclosed in an Attack Resistance Box.
• Both the alarm panel and the SC4000 must be located within the protected premises.
• The telephone cable from the alarm panel to the SC4000 must be enclosed in galvanized steel conduit with
the following restrictions:
− The conduit used must be UL Listed.
− EMT or FLEX type conduit is not acceptable.
− The length of the conduit can not exceed 18 in. (45.7 cm).
− The conduit must be connected to the Panels at both ends with a closed nipple connector.
− The conduit connecting the alarm panel to the SC4000 must be supervised for Opens with a monitoring
loop. Install the monitoring loop utilizing the following procedures:
1.

Run a wire originating inside the SC4000 Radio Communicator through the conduit to the alarm
panel through a 3.3 KΩ 10% tolerance resistor and loop it back through the conduit to the inside of
the SC4000 Panel.

Connect one end of the wire to the positive (+) side of SC4000 Input #1, Terminal #1 “Aux 1.”

Connect the other end of the wire to the negative (-) side of SC4000 Input #1, Terminal #2 “Com.”

If this monitoring loop is cut, the SC4000 will immediately send the message "Open: Input 1" to the
SC9000 computer and the Alarm Event Code "211" will be sent to the automation software.

The text "Open" may be modified using the Input Translation Table (XLAT) to display at the SC9000 computer
any text definition of up to eight characters maximum which properly describes the open condition of the
monitored loop. Ensure text is assigned to the Alarm Event Code "211" in the Automation software, which
properly describes the open condition of the monitored loop.

Pre-Installation Requirements
3.0

Pre-Installation Requirements

3.1

SC4000 Pre-Installation Requirements
Prior to the installation of the SC4000 Radio Communicator, several conditions must be satisfied and physical
phenomena considered to insure trouble free SAFECOM operation.

3.2

Wiring Requirements of the SC4000
All wiring utilized for the installation of the host alarm panel and the SC4000 Radio Communicator must be in
accordance with (IAW) local building codes. The following is recommended gauge and type wiring for installation
of the host alarm panel and the SC4000:
• Alarm panel dialer phone Lines: lAW industry installation standards.
• SAFECOM antenna RF cable : It is usually preferred to mount the factory provided antenna directly on the
SC4000 enclosure.
• SAFECOM antenna RF cable for remote antenna installation (antenna located remotely, away from the
SC4000): For distances of 15 ft. (4.6 m) or less we recommend using RG-58 or equivalent. For distances up
to 30 ft. (9.1 m) we recommend RG-8 or equivalent. For distances exceeding 30 ft. (9.1 m) or more contact a
Radionics SAFECOM Applications Engineer for recommendations.

3.3

AC Power
Primary power for the SC4000 Radio Communicator is an 18 VAC, 40 VA transformer. The transformer requires
a 120 VAC/60 Hz or 220 VAC/50 Hz power source. Connect the transformer to an electrical outlet that is rated at
15A or more.

Note:

The 120V AC, 60 Hz commercial power must be unswitched and from a reliable source.

Note:

For NFPA 72 applications, a dedicated branch circuit must be used to supply the 120V AC, 60 Hz power for the
transformer. The circuit must have a means of being disconnected which is available only to authorized
personnel and identified as a Fire Alarm Communications Panel.

3.4

Backup Battery
The SC4000 is to be installed with a 24-hour rated backup battery to supply power for the system during
interruptions in primary (AC) power. The back-up battery will provide the standby power necessary to meet
NFPA requirements. In accordance with UL specifications, the backup battery will operate as the primary power
source for 24 hours and will charge to full capacity within 24 hours when the AC power source is restored.
The following battery is approved by UL for installation and use with the SC4000 :
• YUASA, model #NP7-12. Maintenance-free, rechargeable sealed lead-acid.
• Nominal voltage = 12 VDC
• Nominal capacity (20 hour rate) = 7.0 AH
• Weight = 6.17 lb. (2.8 kg)

Note:

The SC4000 charging circuit is calibrated only for lead-acid gelled electrolyte (gel-cell) type batteries.

Note:

Radionics recommends battery replacement every 3 to 5 years under normal use. Do not install the transformer
into a power source that is routinely switched off. In addition to violating NFPA requirements, this will prevent
heavy discharges of the battery resulting in premature failure.
During an AC power loss the battery supplies all power to the SC4000. This load slowly discharges the battery.
When the battery voltage drops below 11.5 VDC, the SC4000 will send a "Battery Trouble" message to the
SC9000 Base Station. This alerts the Central Monitoring station that there are only four hours of battery charge
remaining to sustain SC4000 operations.
After the AC power is restored, the SC4000 starts charging the battery until it reaches a voltage of 13.6 VDC. It
will take a maximum of 24 hours for the SC4000 to charge the battery to full voltage capacity.

3.5

SC4000 Radio Communicator Location
The SC4000 enclosure can be mounted directly to a vertical surface, like a wall, using the “keyhole” mounting
holes provided on the rear of the SC4000 enclosure. The factory supplied antenna should be attached to the
antenna connector on the top of the SC4000. In some cases the antenna can be remotely located from the
SC4000. This type of mounting will also require the use of an “L” bracket to mount the factory supplied antenna.
The “L” antenna mounting bracket is Radionics part number #80072-101.

SC4000 Operation and Installation Guide

90002-201C

SC4000
Pre-Installation Requirements
The SC4000 is not environmentally sealed. Do not mount the SC4000 where it can be exposed to
the elements.
CAUTION

If the antenna is mounted directly on the SC4000 enclosure, the SC4000 should be mounted on the inside of an
exterior wall for optimum radio transmission and reception. However, it should not be mounted in close proximity
or on the same wall to:
• A cable bundle and/or wiring harness that is routed vertically and in close proximity to the SAFECOM
antenna.
• A computer, PA, entertainment, or sound system.
The following should be considered when determining the location for mounting the SC4000:
• Antenna proximity to a cable bundle and/or wiring harness.
• Antenna proximity to computer, PA, entertainment, or sound systems.
• Easy access by a service technician.

3.6

Antenna Location
Improper antenna location is the single most common problem found in SAFECOM installations. The only way to
properly determine the best location for the SAFECOM antenna installation is to use the SAFECOM IT1500
Installation Tester.

IMPORTANT

The SAFECOM IT1500 Tester must have a minimum of 9dB of attenuation installed between the
Tester and the Tester antenna. If the Tester, along with the 9dB attenuator, does not produce a
minimum of 10 “pass” indications following 10 tests, then the SAFECOM SC4000 Radio
Communicator cannot be installed in this location. Refer to the SC9000 Operations Manual section
titled “Using the IT1500 Tester” for more information on finding another location within this
building and testing possible antenna locations. For information on ordering an external
attenuator for your SAFECOM IT1500 Tester, contact a SAFECOM Applications Engineer at (800)
538-5807.

A successful RF communications link between the SC4000 and the Central Station SC9000 computer may be
subject to external interference. Several environmental effects must be considered when determining the proper
location for mounting the SC4000 antenna.
Transmission and receipt of radio signals may be blocked by metal, mountains, hills, foliage and other natural
and man made obstructions.
Some extent of radio signal degradation may be seasonal. Weather may significantly degrade reception ranges
due to propagation from temperature layers and reflection from the moisture content in the atmosphere.
Transmission and reception ranges may be reduced by dense foliage on trees and shrubs. This degradation is
normally experienced during the spring and summer months when the presence of leaves tends to block the
signal path. During the winter, snow and ice on rooftops can also have a strong attenuation affect.
For optimum transmission and reception of radio signals, position the antenna as high as possible within the
structure. Mounting the antenna on an elevated structure will enhance the line-of-sight Tx/Rx range and
communications link effectiveness. The antenna should not normally be mounted inside metal buildings or
enclosures. The proper antenna location is site specific for each installation.

IMPORTANT

All sales personnel should be required to utilize the IT1500 Tester with a minimum of 9dB of
attenuation installed between the IT1500 Tester and the Tester antenna to determine if two-way
radio communications between the prospective customer site and the Central Station SC9000
computer is possible.

After the initial testing performed by the salesperson, the installer should be required to utilize the IT1500 Tester,
with a minimum of 9dB of attenuation installed between the IT1500 Tester and the Tester antenna to determine
the proper antenna location within the customer site for installation.
The IT1500 is a portable tester which transmits a radio signal from the remote customer site to the Central
Station SC9000 computer and receives an acknowledge (ACK) message to verify a successful two-way
communications link for that particular geographic location and antenna position.
REMEMBER! Moving the antenna location as little as four inches (10.2 cm) in either direction can mean the
difference between a trouble-free site or an angry customer that requires multiple service calls.

SC4000 Acceptable Antenna Types
The SC4000 is usually installed using the factory supplied omni-directional (OMNI) antenna. However, if testing
using the IT1500 Tester with a minimum of 9dB of attenuation installed between the IT1500 Tester and the tester
antenna shows that the factory supplied omni-directional antenna is not sufficient, the installer may choose to
use a directional, gain antenna. This type of antenna is usually referred to as a “beam” or YAGI type antenna.
The following is a partial listing of acceptable types of antennas for installation on or external to the SC4000
Radio Communicator. Both the omni-directional and YAGI type antennas are available to order directly from
Radionics. Call (800) 538-5807 for more information.

SC4000 Inputs
There are four inputs on the SC4000. The status of each of the four inputs is monitored by an End-of-Line
(E.O.L.) Supervisory Loop circuit. There are three possible states for each E.O.L. supervised loop: Normal,
Open, and Short.
Each SC4000 input can be programmed at the Central Station SC9000 computer for Non-Expanded or
Expanded mode. By using the Expanded mode, monitoring of up to eight (8) AUX Loops is possible. One (1) or
two (2) AUX Loops or Devices can be monitored by each Auxiliary Input, depending on how the inputs are
programmed.

3.8.1

Non-Expanded
A non-expanded auxiliary input must be wired with a 3.3KΩ E.O.L. resistor. This external resistor is wired in
series between the SAFECOM input wire (1,2,3, or 4) and the common ground on the SAFECOM SC4000 (black
wire). See the following figure:

Pre-Installation Requirements
3.8.2

Expanded
A SAFECOM SC4000 can be programmed for Expanded mode. This mode allows the SAFECOM SC4000 to
sense two different independent contact closures per input. When using an Expanded input type, you must wire
the input with a 1.1KΩ

and a 2.2KΩ 1 % precision resistor. See the following figure:

MODE (sensing more than 1 contact closure).
Figure 5: Expanded Mode Wiring
For Expanded SAFECOM inputs, the 1.1KΩ resistor forms the Primary Loop. Status conditions for the Primary
Loops (across the 1.1KΩ) are reported to the Central Station SAFECOM SC9000 computer as “Short” or
“Normal” on the corresponding input, “Input 1”, “Input 2”, “Input 3”, or “Input 4.”
For Expanded SAFECOM inputs, the 2.2KΩ resistor forms the Expanded or secondary Loop. Status conditions
for the secondary Loops (across the 2.2KΩ) are reported to the Central Station SAFECOM SC9000 computer as
“Short” or “Normal” on the corresponding Expanded input, “Input 1X”, “Input 2X”, “Input 3X”, or “Input 4X.”

3.9

SC4000 Relay Outputs
There are four (4) Output relays on each SC4000. Each output controls a Form “A”, one (1) amp, 2-position
contact. The SC4000 can turn on or turn off any device normally controlled by a switch like air conditioners,
pumps, tank valves, sirens, lights, CCTV cameras, access control devices, and arm/disarm alarm panels.
Behavior and control of each individual output Relay is programmed by the Central Station operator in the radio
communicator account Setup #3 menu. The SC4000 can be programmed to enable or disable the individual
relays by one of two methods:
1.

A manual Enable or Disable command is sent to the SC4000, by the Central Station operator each time an
Enable/Disable status change is desired. (Relay output Type - 0). Once an Output Relay status is set, it will
remain in that condition until changed by another manual Enable or Disable command, or if the SC9000
computer is rebooted.

The SC4000 is programmed in its radio communicator account setup with an output Type which defines the
automatic switching by the SC4000 in the field.

The Radionics factory default status of the Output Relays is Disabled. The type of relay contact (Normally Open)
or (Normally Closed) is determined by the position of a shorting plug jumper, just below the respective output
relay on the SC4000 circuit board.

4.3

Antenna
The antenna should be mounted directly on the SC4000 enclosure (see above illustration).
If a remote antenna location is required, mount the antenna in a suitable location as best determined by the
results from the IT1500 Tester (with 6 to 9dB of external attenuation added). Use a 2"x2" Antenna Mounting Lbracket to attach the antenna to a beam or supporting structure.
For remote antenna installations, Radionics recommends using RG-58 for distances up to 15 ft. (4.6 m) and RG8 for distances up to 30 ft. (9.1 m).

4.4

Wiring and Using the SC4000’s Inputs
• Input #1: Connect the Input 1 Terminal to the factory supplied EOL resistor (3.3KΩ) with the other side of the
resistor to the COM terminal on the SC4000. This will produce an “Input 1=Normal” condition. Applying a
contact closure across the EOL resistor will produce an “Input 1=Short” condition.
• Input #2: Connect the Input 2 Terminal to the factory supplied EOL resistor (3.3KΩ) with the other side of the
resistor to the COM terminal on the SC4000. This will produce an “Input 2=Normal” condition. Then applying
a contact closure across the EOL resistor will produce an “Input 2=Short” condition.
• Input #3: Connect the Input 3 Terminal to the factory supplied EOL resistor (3.3KΩ) with the other side of the
resistor to the COM terminal on the SC4000. This will produce an “Input 3=Normal” condition. Then applying
a contact closure across the EOL resistor will produce an “Input 3=Short” condition.
• Input #4: Connect the Input 4 Terminal to the factory supplied EOL resistor (3.3KΩ) with the other side of the
resistor to the COM terminal on the SC4000. This will produce an “Input 4=Normal” condition. Then applying

Optional LS500 Phone Line Voltage Simulator Board
The LS500 Phone Line Voltage Simulator is an optional device which connects to the SC4000 circuit board and
allows it to be used with alarm panels that have a phone line supervision feature. Without the LS500, the
SC4000 provides only 5 volts on the simulated Tip and Ring connections to the host alarm panel. Some alarm
panels do not see enough voltage and will report a phone line trouble.

SC4000
Installation Procedures
When the LS500 is connected the SC4000 is capable of providing approximately 40 VDC to the host alarm
panel. This is usually sufficient to satisfy the alarm panel that the phone line is OK.
Note:

The LS500 will not solve compatibility problems between the SC4000 and opto-isolated type alarm panels (for
example, some DSC and Australian panels). To solve this, the SC4000 must be sent to Radionics for a “DSC
Modification” to the main SC4000 board.
The LS500 must be used with alarm panels that are configured to do phone line supervision. It is also required
for dual-line class B Fire and Security systems. The alarm panel can supervise both the secondary telephone
line from the phone company, and the simulated primary phone line from the SC4000. If the real phone line fails,
the alarm panel can simply send a Phone Failure message to the Central Station via the SAFECOM network. If
the SC4000 fails or detects a problem with the SAFECOM network, it will automatically connect the alarm panel
to the back-up phone line.
In this mode the alarm panel is still required to send test reports on both lines, just as it would if it were actually
connected to two lines.

Installation of the LS500 Phone Line Simulator Board
The LS500 is a small plug-in board which is easily installed on the SC4000 circuit board. Utilize the following
procedures for installing the LS500 Phone Line Voltage Simulator board:
1.

SC4000 system power off. Turn AC off first, then the Battery DC power.

Install the LS500 on the JP7 header with the following steps.

Ensure the component side of the module faces to the left and away from the C8 capacitor.

The wire leads to the C8 capacitor may require a slight amount of bending to provide adequate clearance
spacing for the LS500.

Ensure the 6 pin connector on the LS500 is properly aligned with the pins on the JP7 header.

SC4000 system power on. Turn Battery DC power on first, then the AC. There are no programming
changes necessary.

Note:

•

Backpoll: Backpoll specifies the maximum amount of time a SC4000 will tolerate no radio communications
with the SC9000 computer. Recent changes to the SAFECOM system software have rendered this feature
obsolete.

•

Report Battery Trouble?: If this parameter is set to “Y” for Yes, then the SC4000 will report a low battery
condition to the Central Station if this condition occurs. If “N” for No, the SC4000 will ignore a low battery
condition.

•

Intercept Digital Dialer?: Y or N: Specifies the routing of the host alarm panel’s signals to the Central
Monitoring Station. If "YES" = The alarm panel Dialer messages will be intercepted by the SC4000 and sent
to the Central Monitoring Station via the SAFECOM radio network. If "NO" = The alarm panel Dialer
messages will always be routed to the Central Monitoring Station via the telephone line.

•

Enable Auto Fallback? Y or N: Specifies whether the SC4000 will automatically revert to the phone line
backup in the event of a SAFECOM system failure. If "YES" = The Fallback Mode (telephone Backup) will
be initiated by the SC4000 if the alarm panel Dialer attempts to send an Alarm message via the SAFECOM
radio communications system three (3) consecutive times and for some reason is not successful. If “NO" =
The Fallback Mode will not be initiated. This type of configuration is usually reserved for applications having
no phone lines.

•

Make Dial Tone? - Y or N: Make Dial Tone specifies whether the SC4000 will send a simulated dial tone to
the host alarm panel once the alarm panel prepares to send an alarm signal. If “YES” = The SC4000 will
send the Dialer two 440 Hz tones after Line Seizure. Each tone is 1 second in duration. The 2nd tone is sent
2 seconds after the 1st. If “NO” = The SC4000 will not simulate a dial tone to the alarm panel.
Characteristics of the alarm panel Dialer that the SC4000 will be communicating with dictate the selection for
this entry.

•

Allow Dial Pause?- Y or N: Allow Dial Pause sets the amount of time that the SAFECOM SC4000 will
tolerate no activity after a digit has been dialed before deciding that the Receiver ACK tone should be
transmitted. This sets a timing parameter and must sometimes be experimented with among different alarm
panels to find the best choice.

•

Digital Format: Programming of the SC4000 “format” must match the format that the digital dialer is sending.
The tables below list the available formats and correct parameters. Please note that the PID (Product
Identification Code) in the SC4000 determines how the SC4000 will be programmed.

For older SC4000s, the programming version required the operator to set two parameters, “Dialer ACK: and
“Dialer Format” as shown below.

• Digital XLAT - 0 to 8: The Digital Translation Table (XLAT) parameter tells the SAFECOM SC9000
computer where to look up alarm signals. The translation table (XLAT) gives the operator the ability to
assign a table, and then build the table so that usually cryptic alarm signals like “31” will be looked up in the
translation table assigned, and given a brief English text definition like, “BURG Z1.” This can be very useful
in the unlikely event of an automation system failure. The translation table (XLAT) can allow the Central
Station Operators to process alarms from the SAFECOM SC9000 directly without looking up codes to
understand them. The translation text assigned to the Alarm Event Code is ONLY for display in the
SAFECOM SC9000 computer and is NOT part of the Alarm message sent to the Automation software. Each
Digital Translation (XLAT) table in the SAFECOM computer has 240 possible entries for Alarm Event Code
to text translation/definition. A maximum of 8 characters are available for each Alarm Event Code
translation/definition. IF “0” is selected for the translation table (XLAT) then all alarm signals from this
specific account will be displayed exactly as they are transmitted by the host alarm panel without any
translation/ definition.
Note:

The Digital Translation (XLAT) parameter does not have to be set for the SC4000 to operate properly.
The following illustration shows the third setup menu in the SC9000 computer for programming an SC4000
account. Below is a summary of the parameters necessary to complete the programming of an SC4000 into the
SAFECOM computer. The parameters must be entered, then the operator will “ESCAPE” out and save the data
to complete building the account. Refer to the following illustration of Setup Menu #3:

The parameters required to be programmed are shown in the illustration above and described below:
• Enabled? - Y or N: Entering Yes or No to this parameter will enable or disable the respective input. If an
input is programmed as N for No, the SC4000 will ignore any changes to this input.
• 1X, 2X, 3X, or 4X - Y or N: All of these specify whether the respective Input will be treated as an Expanded
or a Non-Expanded input. “YES” = The Input will be treated as an Expanded Input. The Input can be used
for Expanded monitoring of two (2) Loops through a 1.1 KΩ resistor and a 2.2 KΩ resistor . The 1.1 KΩ
resistor is the Primary Loop for the input specified. The 2.2 KΩ resistor is the Expanded Loop for this input.
“No”= The Input will be treated as a Non-Expanded Input. The Input will be used for Non-Expanded
monitoring of one 3.3 KΩ resistor.
• Delay Short - Y or N: This parameter will program in a delay in the respective input that will retard the
reporting of the input when tripped.
• Fault Short - Y or N: Fault Short specifies whether the status of the Input will be treated as a Fault when a
Short condition is detected across the EOL resistor on the specified Input .
When the input is configured for Expanded, the Primary and Expanded Loops will be individually monitored and
a separate message will be reported when a Short condition is detected. “YES” = The following will occur when a
Short condition is detected on the specified input:
1.

The Loop Fault LED (yellow) on the SC4000 circuit board and the Trouble LED (red) on the SC4000
panel door will illuminate.

A Priority Alert message will blink and an audible tone will sound on the SC9000 computer.

• Delay Open Y or N: This parameter will program in a delay in the respective input that will retard the
reporting of the input when tripped.
• Fault Open- Y or N: Fault Open specifies whether the status of the Input will be treated as a fault when an
Open condition is detected on the specified Input .When the Input is configured for Expanded, the Input will
be treated as a fault if an Open is detected on either the Primary or the Expanded Loop. “YES” = The
following will occur when an Open condition is detected on the specified Input:
1.

The LP Fault LED on the SC4000 panel circuit board and the Trouble LED on the SC4000 panel door
will illuminate.

A Priority Alert message will blink and an audible tone will sound on the SC900 computer.

Installation Procedures
• Gate: This parameter refers to the operation of inputs on SC4000F type fire supervisory water flow and
sprinkler reporting systems and is not applicable to the standard SC4000.
• Input XLAT - 00 to 4F: The Input Translation Table (XLAT) specifies the plain English text definition that
you wish to assign to an Input. The text will be displayed in place of the default messages “Open, Short, or
Normal.” The Input Translation Table has 5 pages with 16 line numbers per page for a total of 80 line
numbers. Each line provides a maximum of 8 characters for English text translation for Normal, Open, and
Short Input conditions. The corresponding text assigned to the respective Input in the translation table is
only for display at the SC9000 computer. It is not part of the message sent to the Automation software. Input
translation gives the operator the ability to allow an input on an SC4000 to report “Temp Hi” or “Temp Lo”
instead of “Input Short” or “Input Open.” This ability can be very useful for processing alarm messages in the
unlikely event of an automation system failure. Each translation table (XLAT) line contains three available
conditions that the operator must define, “Short, Open, and Normal.” These are the only conditions the
SC4000 can detect and report on it’s inputs.
Note:

The SAFECOM ST1000 v2.41 and higher software default values for all new radio communicator inputs are “00”
and the default values for line #00 in the Input Translation Table are Normal, Open and Short.
• Output Type - 00, 01, 02, 03, 04, 07, 08, 09, 0A, 0C, 0D, and 0E: Output Type allows the operator to define
how the output relay will behave. It also defines the response behavior (Manual or Automatic Switching) of
the specified (1, 2, 3, or 4) SC4000 Output Relays. The following describes the available relay types and
how they will behave, as well as sample applications for there usage in the field:
Type

Manually Enabled/Disabled by Operator Commands from the SC9000: The relay is enabled/disabled by
radio commands manually sent by the operator from the SC9000 computer. This type of output is used for
applications requiring the Central Station operator to remotely control various devices (electric doors, air
conditioning, pumps, valves, etc.).

Enabled while Comm Fail: The relay is enabled when the SC4000 experiences radio communication
failure with the SC9000 computer. This can be used to sound a local annunciator (horn, buzzer, LED
indicator) to indicate possible intentional jamming of the radio network is evident. The output relay is
automatically reset to the Disabled position when radio communications to the SC9000 computer is
restored.
Enable while in Fallback Mode: The relay is enabled (as a status follower) when the SC4000 enters
the Fallback Mode (the backup phone line is now connected to the host alarm panel) as a result of a
SAFECOM network failure or a manual command sent by the Central Station operator. This type of
relay output can be used to allow a positive indication that the phone line has been connected directly
to the host alarm Panel. This indication (sometimes called “Download Ready”) at the Central Station is
useful when remote arm/disarm via telephone keypad and downloading of the host alarm panel is
necessary. The Relay is automatically returned to the Disabled position when the SC4000 returns to
the digital Intercept Mode (SAFECOM radio routing or Alarm signals Primary).
Enabled when the SC4000 detects a Low Battery: The relay is enabled (as a status follower) when
the SC4000 detects a battery voltage below 11.5V DC. The relay is automatically returned to the
Disabled position when the SC4000 battery has been charged to a level of 13.6V DC. This can be used
to sound a local annunciator (horn, buzzer, LED indicator).
Enabled while AC Fail: The relay is enabled (as a status follower) when the SC4000 detects a loss of
AC power at the customer site. The relay is automatically returned to the Disabled position when the
AC power at the site is restored. This can be used to sound a local annunciator (horn, buzzer, LED
indicator).
Enabled while HI Priority: The relay is enabled (as a status follower) when the SC4000 detects a line
seizure and dialing by an alarm panel Dialer. This usually indicates an alarm is about to be transmitted
by the host alarm panel. This can be used to sound a local annunciator (horn, buzzer, LED indicator) to
indicate that the host alarm panel is in an alarm state. The relay is automatically returned to the
Disabled position when the SC4000 receives the ACK (Kissoff) from the SAFECOM SC9000. This can
allow local personnel to know that the alarm signal was transmitted and received by the Central Station
SC9000 computer.
Enabled if Any SC4000 Input is in an alarm State: The relay is enabled (as a status follower) when
an alarm (Short or Open) is detected on any of the enabled SC4000 inputs. Any of the SC4000
auxiliary inputs that are set to “Y” for input fault short and/or input fault open. The relay is automatically
returned to the Disabled position when all of the auxiliary input fault conditions return to the normal
condition. This can be used to sound a local annunciator (horn, buzzer, LED indicator) to indicate that
an input loop is in the alarm state.

Description of the Relay Output and Possible Application
Enabled for Corresponding Fault Backup: The relay is enabled (as a status follower) only when the
SC4000 detects radio communications failure with the SC9000 computer and an alarm condition (Short
or Open) on an input loop is detected on the corresponding SC4000 auxiliary input. This can be used to
sound a local annunciator (horn, buzzer, LED indicator) when the input loop is in the alarm state and
the SC9000 cannot send the message due to a SAFECOM network failure. The relay is automatically
returned to the Disabled position when communications are restored with the SC9000 computer and
the corresponding input fault condition returns to normal.
Enabled for Corresponding Input Fault: The relay is enabled (as a status follower) when a fault
condition (Short or Open) on the corresponding input is detected. The corresponding input must be set
to “Y” for “Fault Short” and/or “Fault Open.” With this type of output, output relay 1 is linked to input 1
and so on. This can be used to sound a local annunciator (horn, buzzer, LED indicator) when the input
loop is in the alarm state. It is also common to use this type of output type to allow the SC4000 to
automatically perform a switching function, such as turning on an air conditioner system in response to
a high temperature detection on its input. All relay output control for this type is performed automatically
by the SC4000 not requiring Central Station operator intervention. However, the status of being
monitored and the corresponding relay switching action, if performed by the SC4000, will be
immediately reported to the Central Station operator for documentation and archival purposes. The
relay is automatically returned to the Disabled condition when the input fault condition returns to
normal.
Output Toggled Every Second: The relay is toggled on and then off every 1 second. The relay will
continue to toggle until the output type is changed. This type of output is commonly used to control
automated equipment.
Output Toggled Every Minute: The relay is toggled on and then off every 1 minute. The relay will
continue to toggle until the output type is changed. This type of output is commonly used to control
automated equipment.
Enable While Input Reporting is Pending: The relay is enabled (as a status follower) when an input fault
condition (Short or Open) is detected on the corresponding SC4000 input if the fault has not been
reported. The corresponding input must be set to “Y” for input fault short and input fault open. The relay
is automatically returned to Disabled when the auxiliary input fault condition is reported to the SC9000
computer and/or the corresponding input fault condition returns to normal.

• Output XLAT - 00 to 4F: The Output Translation Table (XLAT) specifies the plain English text definition that
you wish to assign to an output. The text will be displayed in place of the default messages “Enabled” or
“Disabled.” The Output Translation Table has 5 pages with 16 line numbers per page for a total of 80 line
numbers. Each line provides a maximum of 8 characters for English text translation for Enable and Disabled
Output conditions. The corresponding text assigned to the respective output in the translation table is only
for display at the SC9000 computer. It is not part of the message sent to the Automation software. Output
translation gives the operator the ability to allow an Output on an SC4000 to report “Pump On” or “Pump Off”
instead of “Output Enabled” or “Output Disabled.” This ability can be very useful for remote control
applications. Each translation table (XLAT) line contains two available conditions that the operator must
define, “Enabled” and “Disabled.” These are the only conditions an SC4000 relay output can be in and
report.
Note:

The SAFECOM ST-1000 v2.41 and higher software default values for all new radio communicator outputs are
“00” and the default values for line #00 in the Output Translation Table are Enabled and Disabled.
At the SC4000 Terminal Strip, physically connect the following:
• Neg Battery: Connect the negative (-) side of the Battery (black wire) to terminal #23.
• Pos Battery: Connect the positive (+) side of the Battery (red wire) to terminal #24.

Note:

Ensure the battery is connected prior to connecting the AC power to the SC4000. This will prevent the SC4000
from sending a Battery Trouble message to the Automation Software via the SC9000 Receiver.
At the SC4000 Terminal Strip, connect the AC transformer to a duplex electrical outlet.
Ensure that the AC transformer is secured to the duplex electrical outlet. This will prevent
inadvertent AC power loss from jarring or bumping the transformer when plugged into the
electrical outlet.

Establishing Communications with the Central Station SAFECOM SC9000
Computer
To establish radio communications between an SC4000 in the field and the Central Station:

SC4000 Operation and Installation Guide

SC4000
Installation Procedures
1.
Note:

Ensure the correct S/N, PID #, Framer #, and RF Channel are entered in the SC4000’s account in the
SAFECOM computer.

The SC9000 computer is located at the Central Station.
2.

Connect the positive (+ red) and negative (- black) wires from the battery to the SC4000, then connect the
AC power transformer.

The TX LED on the SC4000 should illuminate red (TX) for about one second, then the RX LED should illuminate
to indicate that the SC4000 Radio Communicator is transmitting and receiving. If the TX LED on the SC4000
circuit board does not illuminate to indicate that the system is transmitting during the initialization, a hardware
component failure is possible. When the SC4000 system detects a hardware failure during initialization, the BAT
OK LED on the SC4000 circuit board will blink to indicate a specific type of failure. The blinking will continue (reoccurring) until system power is removed from the SC4000 and/or the hardware discrepancy is corrected.
The following describes the BAT OK LED blinking indications for a hardware failure:
• 1 blink is a ROM failure, component U9 or the CPU, component U6..
• 2 blinks is a RAM failure, component U10.
• 3 blinks is a EEPROM failure in the CPU, component U6.
• 4 blinks is a LOW BATTERY indication, <10.5 VDC.
• LED does not illuminate indicates a CPU failure, component U6.
Note:

If the SC9000 cannot find any radio communicator account with this S/N, the SC9000 will ignore any startup
messages from that particular SC4000.
The SC4000 programming is complete and the SC4000 is on-line and operational for a radio communications
link between an alarm panel Dialer and the SC9000 Receiver.

5.3

Manual Initialization of an SC4000 Radio Communicator
The SC4000 Radio Communicator may be manually Reset and/or Initialized. The Reset and Re-Initialize function
is performed by a sequence involving momentarily installing and removing a shorting plug on the JP6 CPU RST
Header. The Initialization procedure is performed for the CPU of a SC4000 that has previously been Initialized
and programmed. This is often used when an SC4000 Radio Communicator has been in service, then removed,
and placed into another account.
The following procedure will erase all the parameter memory in the SC4000 CPU with the exception
of the CPU serial number.

CAUTION

AC and/or DC power is applied to the SC4000 (power on).

Place a shorting plug on pins #3 and #4 (bottom 2 pins). Leave the shorting plug installed. This allows the
CPU to be initialized.

Initiate a momentary short between pins #1 and #2 (top 2 pins).

This procedure will reset the CPU. The BAT OK LED will blink three (3) times to indicated that the CPU has
been Initialized (zeroized).

Remove the shorting plug from pins #3 and #4.

Again, initiate a momentary short between pins #1 and #2. This will initiate a system reset.
