SYSTEM FEATURES & OPERATION
Introduction
The 7720PLUS self-contained synthesized subscriber radio is the subscriber end of a Long Range
Radio alarm reporting system. As a communications link, by analogy to a telephone-based system,
the 7720PLUS is comparable to a digital communicator connected by telephone line to a central
monitoring station.
Synthesized Frequency Selection
The 7720PLUS can be programmed to operate on any authorized radio frequency. It is not
necessary to stock a separate radio for each frequency the installer supports.
Wireless Reporting
All alarm and status messages are transmitted to the master station network via radio signals, which
means faster and more secure reporting.
Integrated Electronics
The entire radio link equipment, except for the AC power supply unit, including interface,
transmitter, battery and antenna, is housed in a single package, requiring only alarm inputs from a
compatible alarm panel.
Selection of Input Interfaces
The 7720PLUS can monitor alarm inputs from the Ademco ECP interface, discrete 4 zone contact
closures or their electrical equivalent
NOTE: ECP features are compatible only with 685 software revision 4.7 and higher, and
685-5 software revision 8.1 and higher.
Compatibility
The 7720PLUS is compatible with existing installations using ADEMCO equipment or other control
panels. The 7720PLUS can be used in conjunction with digital communicators on the same system,
both acting as backup to one another (use an ADEMCO 659-EN Line Monitor connected to a zone
input to report a line cut to backup a digital dialer), while connecting the radio fault output to a zone
on the dialer.
Built-in LED Indicators
Three LEDs are used to indicate message transmissions, and radio faults. A blinking yellow LED
indicates normal operation. (See LED Table Page 4).
Built-in Tamper Protection
For added protection, built-in cover tamper switches will trigger an alarm whenever the chassis cover
is removed, thus protecting against unauthorized access to the 7720PLUS. The tamper zone number
must be entered during programming to enable tamper reporting. A radio configured for ECP will
automatically report the tamper status to the control panel, as well as to the Central Station
Antenna Included
The 7720PLUS can use either the supplied omni-directional wire antenna, or can use a 7825 outdoor
antenna, 7625 omni-directional antenna, 7625-3DB antenna (if additional gain is required), a 7674, a
7674-13 YAGI antenna (if a directional antenna is required), by using the optional 7720ANT
connector kit. For wall mounting, an optional 7825DP can be used. The supplied antenna mounts
directly to the7720PLUS. The antennas (other than the wire and the dipole) can be mounted
remotely, if desired, using the following pre-assembled coaxial cable, available from ADEMCO: 5ft
–3–
coax (P/N 7626-5), 12ft coax (P/N 7626-12), 25ft coax (P/N 7626-25HC), and 50ft coax (P/N 762650HC).
Programmable Features
The 7720PLUS utilizes EEPROM (Electrically Erasable ROM) technology, which allows the
7720PLUS to be programmed with a 7720P Programming Tool. The programming options include
radio frequency channel number (1 to 14), Telco channel assignments for fault input, inverted trigger
inputs, delayed reporting channels (1-127 seconds delay, if selected), open/close/restore reporting
channels, etc.
Self -Diagnosing Transmitter
Malfunctions of the transmitter, including antenna fault, radio transmitter fault, loss of external
power, and low internal DC voltage can be displayed on the 7720P programming tool or reported on
the ECP interface, as well as being transmitted to the master station, if the fault does not prevent
such transmission. Faults can also trigger contact closures on a Form “C” relay to indicate radio
faults.
Power Supply
The 7720PLUS is powered byan AC wall transformer, part number (TBD), whichprovides 12 volts AC
to the radio on pins 1 and 2 of the terminal block. An internal rechargeable battery provides power to
the radio in the event of AC power outage. This battery is charged from the AC power supply during
normal operation of the radio.
Low Battery Monitoring
The 7720PLUS will notify the central station of a low battery condition whenever the battery voltage
drops below 9.93V (+/- 2%). Low battery restore messages are reported “” when the battery voltage
reaches 10.03V (+/-2.5%). A radio configured for ECP will report the battery status to the control
panel as well as to the central station.
Low Battery Shutdown
In the absence of AC power, if battery voltage drops below 9.45 volts, the 7720PLUS will
automatically shutdown and ALL LEDs WILL BE OFF. However, so long as there is AC power, in the
normal range of 102 to 138 VAC at the wall outlet, the radio will operate properly, regardless of the
condition of the battery.
General Operation
The 7720PLUS receives alarm and restore signals from the alarm control panel and converts these
signals to radio messages which are transmitted to the master station network, which in turn relays
the messages to the central station. The 7720PLUS can monitor 4 traditional zone inputs or an ECP
signal line from an appropriate control panel. The first two zones may be configured by the use of a
jumper, to activate on either 0 volts or 4.5-14.2VDC; zones 3 and 4 are hard-wired to activate on 4.514.2VDC. Zones 1-4 can also be programmed to invert the sense of their input signals. (Zones
normally are activated when the signal goes to a positive voltage. Inverting the zone trigger means
that the zone will be activated when the signal goes to ground. The pull-up voltage for zones 1 and 2
can be supplied by changing a jumper, if desired; pull-up voltage for any of the zones can be supplied
from the radio thru external resistors, or from an alarm panel.)
Upon detecting an alarm or restoral, the 7720PLUS will transmit the messages to the master station
network.The transmissions will repeat for approximately 6 minutes (total of 60 messages) to ensure
that the alarm or other report will be received by the central monitoring station.
The 7720PLUS periodically transmits supervisory status messages to the AlarmNet network. Radio
faults that are indicated during transmissions may prevent communication; to prevent this, the fault
output (available in zone mode only) can be programmed to also indicate radio faults (programming
–4–
the fault output is explained later in this chapter). If no messages are received during the supervisory
window, the network will generate a communication failure signal to the central station.
Available in zone mode only is a contact closure used to locally indicate a radio fault. This can be
either normally open or normally closed. In addition it can be selected to be “fail-safe” by
programming the fault output to be inverted (i.e. the relay is powered unless there is a fault). The
fault output is between TB1-11 and TB1-12, which float with reference to the rest of the circuit.
Also available in zone mode only is the ability for the 7720PLUS to provide status information via its
serial port, thus allowing radio status to be displayed on command, using either a 7720P
Programming Tool or a computer terminal. Refer to the TESTING THE 7720PLUS section for
information regarding the “S” command and status messages.

Low Battery Detection & Restoral
Low Battery Detection
The radio tests the condition of the batteryperiodically. If the radio finds that the battery is low, a low
battery warning message will be transmitted. When the battery voltage restores, the radio will
transmit a battery restore message.
Battery Charging Mode
The battery is under continuous float charge whenever the AC power is connected and sufficient.

SETTING THE JUMPER OPTIONS (Set Before Installing)
Removing The Cover
Remove the 7720PLUS’s cover by inserting a screwdriver into the 4 removal points at the bottom of
the unit and gently releasing the locking tabs from the cover slots as shown.
(J2) Zone Inputs Activate on High or Low
If using zone input connections, set the J2 jumper so that zone 1 & 2 inputs are activated either with
a ground or with a positive voltage, whichever is required.
If the trigger level is set for positive voltage, +4.5 to +14.2 volts must be applied to zones 1 & 2 to
trigger an alarm. If the zone is connected to a normally high voltage trigger (i.e. goes low on alarm),
invert this zone when programming (questions 13 and 14).
If ground is selected, zones 1 & 2 are internally pulled up to 5 volts through a 10k ohm resistor. This
voltage should normally be pulled down (closed contact to ground) and released for alarm (opening the
contact). If a normally open contact is being used, invert this zone when programming (questions 13
and 14).
(J3) Fault Output Select
Refer to the diagram on the following page when setting jumpers.
–7–
The radio fault output relay may be programmed for either FAIL-SAFE mode (relay always
energized) or LOW CURRENT mode (relay normally de-energized) by selecting Yes or No to
programming question 27: FLT REL ON (Y/N). In addition, the relay can be set for either N.O. or N.C.
operation (in either fail-safe or low current modes) using the J1 jumper. When fail-safe mode is
selected, the relay will change states (and trigger a dialer, if connected) in the event of power loss.
Note that fail-safe mode increases the standby current by about 10mA, which results in lower battery
backup time (about 15%) in the event of power loss. Set the J1 jumper to position A or position B, as
follows:

Trigger voltage outputs: A current-limited source of approximately 12 volts DC is available at pin 3
of the terminal block, for external contacts, etc., that require a pullup voltage.
NOTE: Use color-coded wires for the power connections; it is recommended that the positive connection
be red and the negative connection be black.
Wiring At The Control Panel
’.
Connect the negative wire to the system negative point, which is also the negative line from the
battery.
Run the alarm wires to the transmitter location.
Wiring For ECP Communication with a Control Panel
Only certain panels support ECP data communication at this time.
Instructions of your panel to see if Long Range Radio is supported.
Check the Installation
ECP data connections are the Data In and Data Out terminals that the keypads and other peripheral
devices (RF Receiver, VIP module, etc.) use for communication with the panel. To wire the radio for
ECP communication, do the following:
Connect TB1-4 (Ground) of the 7720PLUS to the ground of the panel.
Connect TB1-5 (ECP DATA IN) of the 7720PLUS to “data out to consoles” connection on the panel.
Connect TB1-6 (ECP DATA OUT) of the 7720PLUS to “data in from consoles” connection on the panel.
Note: add ground wire to drawing below. (See page 10a)

Recommended Wiring At The 7720PLUS
The alarm and power wires can be brought into the transmitter through the base, or through the
cover. If they are to be brought through the cover, cut out the optional wire entry port. Connect the
AC power wires from the transformer to TB 1-1 and TB 1-2, respectively. Install the battery into the
battery holder, but do not plug in the battery cable yet.

Mounting
Determine the best antenna location for strong radio communication with the Master Station network
using the 7715DFFAST Tool (see pages 21 - 23). Mount the 7720PLUS to a horizontal or vertical
surface, depending on the antenna used. Be sure to allow access to the programming port when
mounting. The 7720PLUS is intended to be mounted to a horizontal surface, preferably on a ceiling,
or in an attic location on top of a joist when using the supplied wire antenna. If using the 7720ANT
antenna kit, the 7720PLUS can be mounted to a vertical surface such as a wall or beam.
Powering Up
After all wiring is complete and the unit is mounted, plug the battery cable of the 7720PLUS into
the connector next to the terminal block, then apply power to theradio. The radio will rapidly flash
each LED consecutively for a total time of about 2.5 seconds. During this time, the user can configure
the radio to operate in zone mode (four zone inputs) or in ECP mode, where alarm input is received
from the control panel via the ECP interface. See “Choosing Mode” in the Programming Section.

PROGRAMMING THE 7720PLUS
Using A 7720P Programming Tool
The 7720P Programming Tool is powered by the 7720PLUS, and connects to the telephone connector
on the 7720PLUS PC Board. Please note the the 7720P is not functional when the radio is running in
ECP mode; it is functional only during power-up of an ECP radio.
IMPORTANT NOTE: Some of the older 7720P tools (those shipped prior to mid-1998) will
not function if the line voltage is too low. These can be modified using instructions
supplied on request, or they may be returned to Ademco for factory modification. All 7720
P tools currently shipping will work without difficulty.
Each key of the 7720P has two possible functions, a normal function and a SHIFT function. To
perform a normal key function, simply press the desired key. To perform a SHIFT key function, press
SHIFT key, then press desired function key.

CHOOSING MODE: ECP OR ZONE
Using the 7720P, the user can enter the configuration set-up by pressing the enter key while the
individual LEDs rapidly flash sequentially. This will cause the radio to display the following prompt
on the 7720P display:
ECP Radio[Y/N]
– 12 –
The radio will wait 10 seconds for a response. If the radio receives no response or something other
than a “Y” or an “N”, the radio will use the configuration stored in EEPROM. The default
configuration is Zone mode. If the configuration has changed, the EEPROM MUST be
reprogrammed.
If the new configuration is ECP mode, and the panel used is not capable of programming the radio,
the 7720P can be used during the power-up sequence (See ECP Mode Unique Programming section,
page 18). If the new configuration is zone mode, the 7720PLUS signon will appear immediately and
programming may begin. If the 7720PLUS has been programmed for the given configuration, the
LEDs will flash according to their functions. If the 7720PLUS has not been programmed, regardless
of configuration, the LEDs will flash in unison indefinitely.
Zone Mode Unique Programming
After connecting the 7720P cable, power up the 7720PLUS (plug in the battery connector and apply
power to the control panel). The following will be displayed:
ADEMCO 7720 4.xx
© Pittway 1996
4.xx = current software revision level
Programming is accomplished by answering displayed questions. Most questions require only a [Y]es
or [N]o response, while others require a numerical response (ID numbers, etc.). Press ENTER to
accept each response and proceed to the next question. A “?” indicates an invalid entry. The current
value is displayed on the second line in parenthesis (). To accept the current entry, simply press the
ENTER key. Use the UP/DOWN arrow keys to scroll through the programming questions without
changing any values.
Enter programming mode by pressing [ENTER] during the initial power up period (while LEDs are
flashing consecutively).
Pressing SHIFT-X will reset the 7720PLUS to its initial power up phase if it has already entered
program mode. The 7720PLUS reads its EEPROM to determine its pre-programmed parameters. A
CRC of the EEPROM locations is also read. If the computed CRC does not match the one read from
EEPROM or if the programming parameters are invalid, the 7720P LCD displays “NO PROG”. While
the three LEDs flashes in unison, press ENTER to begin programming.

PULSE/DELAY ZONE SELECTION
By configuring a zone as a pulsed zone, it is possible to use the output of a panel bell/siren driver to
activate the radio directly when the signal from this driver is a pulsed output for fire and a continuous
output for Burglary. To implement a Fire/Burg. detection at the radio, connect the driver output directly
to two zones on the 7720PLUS. Program the Fire zone as a pulsed zone and the Burglary Zone as a
delayed Zone (this is to prevent this zone from reporting an alarm when the pulsed signals are detected).
The number of pulses and the length of delay will be dependent on the particular panel or siren driver
being used and is therefore a programmable feature.
Note: Zones programmed for pulse cannot be designated as open/close or Telco zones; an invalid entry
message will occur, since the pulse zone takes priority over open/close and Telco programmed zones.
UL Note: The control unit total delay shall not exceed 14 seconds in UL Listed applications if “yes”; 0.30
seconds if “no”.

RESTORAL REPORTING ZONE SELECTION
Restoral reporting can be enabled, disabled or delayed. The delay option delays Restoral reporting for
about 1.5 minutes after the actual restore condition, which helps ensure that alarm messages reach the
central station before the restore message. Note that if restores are enabled for a delayed zone, the
restore condition must exist for at least 2.5 seconds (this is intended to prevent swinger conditions). If
any of the zones have been programmed for pulse operation, then, following the Restoral question, the
7720P will display “REST ON CHG (Y/N)”. This feature is used for zones connected to the bell output of a
panel, and when enabled (Y) will report the zone in restoral when the pulse train stops and a steady state
level, either high or low, is left on the zone input or when the steady state level starts pulsing. If this
feature is not enabled (N), the zone will only restore on a steady state low logic level.

ANTENNA MOUNTING
Selecting A Location
If Non UL installation, an antenna location which has reliable communications with at least one
base station with an uplink signal strength reading of “3” or greater may be used .
NOTE: Place a check mark [✔
✔ ] in the “Single Site Supervision” box on the Subscriber
Contract.
For UL Grade “A” or Grade “B” installations, find an antenna location which has reliable
communication to at least two AlarmNet Base Stations with a minimum uplink signal strength
reading of “3”.
After determining the type of installation required (UL, Non UL) find an antenna location
within the premises. Locations can be found by utilizing the test mode of the 7720PLUS (see
TESTING THE 7720PLUS section), the 7715 FAST Tool or the 7920 series transceiver.
Notes On Antenna
Mounting
1. Optimum RF performance can usually be found at the highest
point within a building, with the fewest number of walls
between the radio and the outside of the premises.
2. Avoid mounting the antenna near other electronic devices. The following
table provides minimum distances. Highest RF energy is in the direct,
horizontal line of the antenna. Therefore, vertical separation (moving
electronic devices either higher or lower on wall) provides a higher level of
isolation from the radio.

TESTING THE7720PLUS
Radio Transmission Test
The 7720PLUS is capable of sending a test message, which can be received by the central station to
confirm the radio’s communication link to the central station.
For AlarmNet users, the test message will cause the master station network to send a “Field
Triggered Diagnostic Message” to the Central Station. This message provides network information as
well as signal strength and frequency characteristics of the transmitted messages. Refer to the
AlarmNet User’s Guide for detailed information concerning these messages. The test message can be
transmitted in any of three ways. Please note that methods 2 and 3 are available in Zone mode
ONLY. Check control panel Installation Instructions if LRR Test Mode feature is supported.
1) The TEST INPUT of the 7720PLUS can be triggeredby shorting the two pins of the test connector
together using a screwdriver, dime, etc., This will initiate a 90 second cycle (total of 60 messages) of
test message transmissions. Note that once this cycle has been initiated by a voltage trigger, it can be
turned off by using the T command described in (2). Otherwise, the messages will not stop until the
end of the cycle.
2) A 7720P Programming Tool can be used, if the radio is operating in zone mode. To begin the cycle
of test message transmissions, press SHIFT-8 (T command). This is a toggle function. To end the
transmissions before the end of the cycle, simply enter the command again. See the NOTE on page
25.
3) A computer terminal can be used, if connected to the programming connector of the 7720PLUS. To
begin a cycle of test message transmissions, press “T.” This is a toggle function. To end the
transmissions before the end of the cycle, simply enter the command again.
System Test
Trigger an alarm by any convenient means and observe the LED indicators on the radio. The yellow
LED should light solidly, followed by the green LED flashing every 1-3 seconds at first, then slowing
during the 6 minute cycle. This indicates that an alarm message has been received at the radio
(yellow), and the transmitter has been activated (green). The red LED should not light.
If the radio is configured for zone mode and the zone is programmed for restore, restore the circuit.
The yellow LED should light solidly, and the green LED should flash again, indicating transmission of
the restore message. The central station receiver should display alarm/restore messages for each
triggered alarm/restore performed.
If at any time the red LED lights, a radio fault has been detected. This could be caused by a faulty
antenna connection, or might be caused by low internal battery voltage, or a failure in the radio’s
power circuits (see LED FLASH PATTERNS on page 4).
If the radio is in Zone mode, the 7720PLUS can display diagnostic data (S command) related to the
status of these conditions. See Status Command section.
If the radio is in ECP mode, the status is displayed on the control panel’s remote keypad in the lower
right-hand corner. This display is in the form of a four-digit numeric output (usually preceded by
“Long Rnge Fail”). Please see description of codes in ECP Status Codes section.
Replace the cover (if it was removed) and perform a control panel system test.
– 29 –
Status Display Interpretation for
“S” Command.(Available in Zone mode ONLY)The status of the
7720PLUS can be viewed on either a 7720P Programming Tool or an appropriate terminal when

ECP Status Codes
When the 7720PLUS radio is set up in ECP mode, it sends to the control panel the status of its
battery, the incoming AC voltage, the tamper and any RF failures. The status is displayed on the
control panel’s remote keypad in the form of a four-digit numeric usually preceded by the label “Long
Rnge Fail”. These codes will not clear from the remote keypad until a code-off sequence is entered
and the fault condition has cleared. The status codes are broken out as follows:

– 31 –
Last Detected Fault “E” Command
(Available in Zone mode ONLY)
The last detected radio fault and the last reported radio fault can be viewed by pressing “E” on a
7720P Programming Tool or an appropriate terminal when either device is connected to the serial
port of the 7720PLUS.
The message is a 2-line display where the top line identifies the last fault that the 7720PLUS detected
and the second line identifies the last fault that the 7720PLUS actually reported to the monitoring
network. The last detected fault represents a fault that occurred on at least one transmission, but
did not necessarily trip the fault relay. The last reported fault is a fault that was present for a
number of transmissions (typically at least 4 consecutive transmissions) and which tripped the fault
relay. The possible fault numbers are described in the “S” command paragraph above. If the detected
fault does not match the reported fault value, and the transmission cycle has finished, it indicates
that the fault was not present long enough for the radio to report the condition.
These values are stored in EEPROM and will be retained even when the 7720PLUS is powered down.
To erase the numbers from memory, press ESC (shift BS) as the next keystroke after pressing “E”.
The fault value is also erased automatically upon exiting program mode.
NOTE: Since the execution of this command requires access to the RJ11 connector, the antenna and
cover must be removed. By doing so, the radio will detect an RF fault as well as a tamper. To prevent
this fault from overwriting a previous fault, the radio does not write the last reported fault to
EEPROM if a tamper is detected.

“FEDERAL COMMUNICATIONS COMMISSION
(FCC) STATEMENT”
This equipment has been tested to FCC requirements and has been found acceptable for use. The FCC
requires the following statement for your information:
This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in
strict accordance with the manufacturer’s instructions, may cause interference to radio and television
reception. It has been type tested and found to comply with the limits for a Class B computing device in
accordance with the specifications in Part 15 of FCC Rules, which are designed to provide reasonable
protection against such interference in a residential installation. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
• If using an indoor antenna, have a quality outdoor antenna installed.
• Reorient the receiving antenna until interference is reduced or eliminated.
• Move the receiver away from the transmitter.
• Move the antenna leads away from any wire runs to the transmitter.
• Plug the transmitter into a different outlet so that it and the receiver are on different branch circuits.
If necessary, the user should consult the dealer or an experienced radio/television technician for additional
suggestions.
The user or installer may find the following booklet prepared by the Federal Communications Commission
helpful:
“Interference Handbook”
This booklet is available from the U.S. Government Printing Office, Washington, DC 20402. Stock No.
The user shall not make any changes or modifications to the equipment unless authorized by the Installation
Instructions or User’s Manual. Unauthorized changes or modifications could void the user’s authority to
operate the equipment.
TO THE INSTALLER
Regular maintenance and inspection (at least annually) by the installer and frequent testing by the user are
vital to continuous satisfactory operation of any alarm system.
The installer should assume the responsibility of developing and offering a regular maintenance program to
the user as well as acquainting the user with the proper operation and limitations of the alarm system and
its component parts. Recommendations must be included for a specific program of frequent testing (at least
weekly) to insure the system’s proper operation at all times.
THE LIMITATIONS OF THIS RADIO COMMUNICATIONS SYSTEM
While this 900 MHz Long Range Radio communications system is part of an advanced and sophisticated
security system, it does not offer guaranteed protection against burglary or fire, nor does it guarantee
communication of burglary or fire warning signals to a central station. Any alarm system, or any
communications system, whether commercial or residential, is subject to compromise, or failure to warn, for
a variety of reasons. Examples of some of these reasons are:
•
•
•
Intruders may gain access through unprotected openings or have technical sophistication to bypass an
alarm sensor, and then disconnect an alarm communicating radio transmitter.
Signals sent by 900 MHz radio transmitters may be blocked by metal, mountains, hills, foliage and other
natural and man made obstructions before they are received by a master receiving station or sent to a
central station. Even a path previously verified as acceptable may periodically change its characteristics.
Long-range radio communication transmitters will not work without power. Radio transmitters require a
battery to work properly in the absence of A.C. power. A weak or dead battery, or improperly installed
batteries may prevent these devices from functioning properly if A.C. power is disrupted for any reason.

•
Radio communication systems are subject to external interference, natural or man-made, intentional or
coincidental, that may keep a signal or group of signals from being successfully received by a master
receiving station or a central station. In addition, one-way radio communication devices receive no
acknowledgment from a master receiving station that their signals are being successfully received.
Signals transmitted may clash with those transmitted from other systems. While statistical estimates
predict successful operation, if the guidelines in the system manuals are followed, the operation of this
system is still probabilistic in nature and may be subject to random signal failures.
• Radio communication devices may change their characteristics over time. Such parameters as frequency,
modulation and power should be properly monitored periodically, with required adjustments made by
qualified personnel.
• Radio communication devices must be installed by qualified personnel. Improper installation or selection
of a transmitter’s location may cause intermittent or unreliable performance.
Any electronic or mechanical device can fail. The most common cause of an alarm system or a radio
communications system not functioning properly when an intrusion or fire occurs is inadequate
maintenance, maintenance that is intended to find such failures as soon as possible. This alarm and
communication system should be tested weekly to be sure all sensors and transmitters are working properly.
Installing an alarm system may make one eligible for lower insurance rates, but an alarm system is not a
substitute for adequate insurance. Homeowners, property owners, business owners and renters should
continue to insure their property and lives.
