SYSTEM FEATURES
Wlreless 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, including interface,
transmitter, power supply, battery and
antenna, is housed in a single unit, requiring
only battery charging power and alarm
inputs from a standard 12 volt alarm panel.
Selection of Input Interfaces: The
7720 can monitor alarm inputs from
Ademco ACP, Ademco ECP. discrete 4
zone contact closures or their electrical
equivalent, or from external gate and
modulation inputs.
Compatibility: The 7720 is compatible
with existing installations using ADEMCO
equipment or other control panels. The
7720 can be used in conjunction with
digital communicators on the same
system,. both acting as backup to one
another (use an ADEMCO 659-EN tine
Monitor connected to a zone input to report
a line cut and 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, low battery conditions and
radio faults. A blinking yellow LED
indicates normal operation.
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 7720.
The tamper zone number must be entered
in programming question 25 to enable
protection.
-2-
Antenna Included: The 7720 comes
with an omni-directional wire antenna, and
also features an optional antenna kit
(7720ANT) for using a 7625 antenna.
Programmable Features: The 7720
utilizes EEROM (Electrically Erasable
ROM) technology, which allows the 7720 to
be programmed with a 7720P Programming
Tool. The programming options include
channel assignments for Telco fault input,
inverted trigger inputs, delayed reporting
channels (16 second delay, if selected),
open/close/restore reporting channels,
etc.
Self-Diagnosing Transmitter:
Malfunctions of the transmitter, including
antenna fault, low output power, loss of
external power, low internal DC voltage and
internal radio-frequency circuit problems
can be reported on both the ACP/ECP
interfaces, as well as being transmitted to
the master station network. if the fault
does not predude such transmission. For
other alarm panels, faults can trigger
contact closures on a Form ‘C’ relay to
indite radio faults.
Power Supply: The 7720 is powered by
its own 12 volt battery, which can be
charged by an alarm panel’s output voltage
(14.0-14.2VDC). The charging input draws
approximately 50mA continuous and
40OmA peak current during transmission.
Low Battery Monitoring: The system
will notify the central station of a low
battery condition whenever the battery
voltage drops below 11.2V (& 5%).
Low Battery Shutdown: If for any
reason the battery voltage drops below
9.75 volts, the radio will automatically
shutdown. Refer to the LOW BATTERY
SHUTDOWN section for more information.

OPERATION
GENERAL: The 7720 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 7720 can monitor either 4 traditional
zone inputs, or can process serial data
from panels which use either ACP or ECP
data formats. For traditional zone inputs,
the first two zones may be configured by
jumper to activate on either 0 volts or
activate on 4.512VDC; zones 3 and 4 are
hard-wired to activate on 4.512VDC.
Zones 1-4 can also be programmed to
invert their input signals.
Upon receiving an alarm, restore, or status
message, the 7720 will transmit the
message to the master station network
after a programmed delay of either 250
milliseconds or 16 seconds. 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 7720 transmits periodic supervisory
messages to alert the central station to
system problems. A contact closure is
available to 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
TBl-1 and TBl-2, which float with reference
to the rest of the circuit.
The n20 also provides 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 7720 section for information regarding
the ‘s’ command and status messages.
ANTENNA:The 7720 can use either the
supplied wire antenna, or, by using the
optional 7720ANT connector kit, can use a
7625 omnidirectional antenna, 7625-3dB
antenna (if additional gain is required), a
7674 or 7674-13 YAGI antenna (if
directional antenna is required). The
supplied antenna mounts directly to the
7720. The other antennas can be mounted
remotely (if desired) using preassembled
coaxial cable available from ADEMCO (5’.
12’or 25’ lengths).
LOW BATTERY SHUTDOWN: If
battery voltage drops below 9.75 volts, the
7720 will automatically shutdown, and ALL
LEDs WILL BE OFF. When the battery is
recharged to 10.25 volts, the LEDs will
begin to flash in rapid unison (see LED
table), until the battery is charged to 12.5
volts. During the charging cycle,
the 7720 &ill not transmit any
messages. The 7720 will resume normal
operation after the battery is fully charged.

SETTING THE JUMPER OPTIONS
(Set Before Installing)
(52) Zone Inputs Activate on High
or Low: If using zone input connections,
set the J2 jumper so that zone 1 8 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 +12 volts must be applied
to zones 1 8 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 8 & 9).
if ground is selected, zones 1 812 are
intemaily pulled up to 5 volts through a 1Ok
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 8 8 9).
(31) Fault Output Select: 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 13: 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 Jl
jumper. When fail-safe mode is selected,
the relay will change states (and trigger a
dialer, if connected) in the event of pouver
loss. Note that fail-safe mode increases
the standby current by about lOmA, which
results in lower battery backup time (about
15%) in the event of power loss. Set the Jl
jumper to position A or position B,
according to the following table:
I Pos. A ]
I w I 1 ‘U.O.
VCC ’ K: 1
NC.
(53) ACP/ECP Select: If the ACP or
ECP interface will be used, then set the J3
jumper as indicated for the desired mode.
When connected to the 7720P
Programming Tool, the jumper should be
set in the ECP mode.
REMOVING THE COVER
qemove the 7720’s cover by inserting a

WIRING, MOUNTING & POWERING
NOTE: Use coior-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:
1. Using an ohm meter, measure the
resistance from the battery positive
terminal to the auxiliary power taksofl
point on the terminal board. if the
resistance is zero ohms, then this
auxiliary We-off point may be used. if
it is greater than zero ohms, then the
positive Power wire for the radio will
have to be spliced to the positive wire
coming from the battery.
IUPORTANT: If the take-off
point Is not fuwtd, a 1A lnllne.
fuse must be put In line at the
control.
2. Connect the negative wire to the
system negative point, which is also
the negative line from the battery.
MOUNTING
5. The 7720 is intended to be mounted to
a horizontal surtace, 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 7720 can be mounted to a
vertical surface such as a wall or beam.
After determining the best location for
strong radio communication with the
Master Station network using the FAST
Tool, mount the 7720 to a horizontal or
vertical surface, depending on the
antenna used. Be sure to allow access
to the programming port when
mounting.
POWERING UP:

INSTALLATION NOTICE
for 7720 SUBSCRIBER RADIO
BATTERY CHARGING VOLTAGE
The n20 is powered from its internal battery. This battery can be charged
from a control panel whose output voltage (from either its auxiliaryoutput or
directly from its battery) is between 14.0 and 14.2VDC, or can be charged
from its own internal charging circuit when used with an Ademco 1324
(12VAC,40VA)WallTransformer.
The 7720’s charging input will draw approximately 5OmAcontinuous and
4OOmApeak current.
lf the control panel being used cannot supply
the requited voltage and current, a 1324 Transformer must be
used In order to guarantee battery life and radio performance.
If using the 1324 Wall Transformer, a suitable 11OVACreceptacle must be
located. The receptacle’scircuit should not be switchable or be in a location
where it is likelyto be tampered with. Make connections using 20 gauge or

TESTING THE 7720
RADIO TRANSMISSION TEST
The 7720 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 AbrmNet 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.
1)The TEST INPUT (terminal 9) of the 7720
can be triggered with a voltage trigger,
which will initiate a 6-6 minute cyde (total
of 60 messages, repeated about once
every 3 seconds) of test message
transmissions. Note that once this cycle
has been initiated by a voltage trigger, it
can be turned off by using the 1 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 connected to the programming connector
of the 7720. To begin a cycle of test
message transmissions, press SHIFT-6 (T
command). This is a toggle function. To end
the transmissions before the end of the
cycle, simply enter the command again.
3) A computer terminal can be used, if
connected to the programming connector
of the 7720. To begin a cycle of test
message transmissions, press SHIFT-T (T
command). This is a toggle function. To
end the transmissions before the end of
the cycle, simply repeat the command.
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 sn
alarm message has been received at the
radio (yellow), and the transmitter has
been activated (green). The red LED
should not light.
If 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
cirouits (see LED FLASH PATTERNS on
page 3). The 7720P can display diagnostic
data (.S command) related to the status of
these conditions. See Status Command
section.
Replace the cover (if it was removed) and
perform a control panel system test.

“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 strii 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 aazordance with the specifications in Subpart J of 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. tfthis 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:
. tf using an indoor antenna, have a quality outdoor antenna installed.
l Reorient the receiving antenna until interference is reduced or eliminated.
. Move the receiver away from the transmitter.
l Move the antenna leads away from any wire runs to the transmitter.
l 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 mayfind 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. 004-000-00450-7.
The user shall not make any changes or modifications to the equipment unless
authorized bj the installation Instructions or User’s Manual. Unauthorized
changes or modifications could void the user’s author&yto operate the
equipment.
TO THE INSTALLER I
Regular maintenance and inspection (at least annually) by the installer and

THE LIMITATJONS 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 01
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 01
these reasons are:
b Intruders may gain access through unprotected openings or have technical
sophistication to bypass an alarm sensor, and then disconnect an alarm
communicating radio transmitter.
b 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.
1 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 prevenl
these devices ,from functioning properly if A.C. power is disrupted for any
reason.
1 Radio communication systems are subject to external interference, natural or
man-made, intentional or coincidental, that may keep a signal or group oi
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.
1 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.
1 Radio communication devices must be installed by qualified personnel,
Improper installation or selection of a transmitter’s location may cause
intermittent or unreliable performance.
4ny 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
ntended to find such failures as soon as possible. This alarm and communication
;ystem should be tested weekly to be sure all sensors and transmitters are
workingproperly.
nstalling an alarm system may make one eligible for lower insurance rates, bul
in alarm system is not a substitute for adequate insurance. Honieowners,
lroperty owners, business owners and renters should continue to insure theil
lroperty and lives.
