INSTALLATION INSTRUCTIONS
Introduction
The 7720 selkontained subscriber radii is the subscriber end of aLong Range
Radio alarm reporting system. As acommunications link, by analogy to a
telephone-based system, the 7720 is comparable to adigital communicator
connected by telephone line to acentral monitoringstation.

SYSTEM FEATURES
Wireless Reporting: All alarm and Antenna Included: The 7720 comes
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 masingle unk requiring
only battery charging power and alarm
inputs from a standard 12 volt afarm panel.
Selection of Input Interfaces: The
7720 can monitor alarm inputs from
Ademcc 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 Line
Monitor connected to azone rnputto report
afine cut and backup ad~ital dialer), whiie
connecting the radm fauft output to azone
on the dster.
Built-in LED Indicators: Three LEDs
are used to indicate message
transmissions, low battery condtions and
radio faults. Ablinking yellow LED
rndbates normaf O~RdkX1.
Built-in Tamper Protection: For
added protection, built-in cover tamper
switches will triggeran afarm 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.

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 programmedwith a7720P Programming
Tool. The programming options incfude
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, bw internal DC vottage 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 prectude such transmission. For
other alarm panels, faults can trigger
contact cfosures on aForm ‘C” relay to
rndicate 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.O-14.2VDC). The charging input draws
approximately 50mA continuous and
400mA peak current during transmission.
Low Battery Monitoring: The system
will notify the central station of alow
battery condition whenever the battery
voka~ drops bdOW 11 .2V (t 5’Yo).
Low Battery Shutdown: If for any
reason the battery voltage drops Mow
9.75 volts, the radio will automatically
shutdown. Refer to the LOW BAllERY
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
refays the messages to the central station.
The 7720 can monitor either 4traditional
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 Ovolts or
activate on 4.5-12VDC; zones 3and 4are
hard-wired to activate on 4.5-12VDC.
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 aprogrammed delay of either 250
milliseconds or 16 seconds. The
transmissionswill repeat for approximately
6minutes (total of 60 messages) to ensure
that the alarm or other report will be
received by the central monitoringstation.
The 7720 transmits peridIc supervisory
messages to alert the central station to
system problems. Acontact closure is
avaifabie to indicate aradio fault; this can
be either normally open or normafly closed.
In adcMin, it can be selected to be “fail-
safe” by programming the fault output to be
inverted (i.e. the relay is powered unfess
there is afauft). The fauft output is between
TB1-1 and TB1-2, whii float with reference
to the rest of the circuit.
The 7720 also provides status information
via its serial port, thus allowing radio
status to be dispfayed on command, using
either a772oP Programming Tool or a
computer terminal. Refer to the TESTING
THE 7720 section for informationregarding
the “S command and status messages.
ANTENNA:The 7720 can use either the
supplied wire antenna, or, by using the
optional 7720ANT connector I@ can use a
7625 omnidkectional antenna, 7625-MB
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 pm-assembled
coaxial cable availabie 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 will not transmit any
messages. The 772o will resume normal
operation after the battery is fully charged.

SETTING THE JUMPER OPTIONS
(Set Before Installing)
(J2) Zone Inputs Activate on High
or Low: If using zone input oonneotions,
set the J2 jumper so that zone 1&2inputs
are activated either with aground or with a
positive voftage, whiohever is required.
if the trigger level is set for positive
voftage, +4.5 to +12 vofts must be applied
to zones 1&2to trigger an alarm. If the
zone is connected to anormally high
voltage trigger (i.e. goes low on alarm),
invert this zone when programming
(questions 8&9).
if ground is selected, zones 1&2are
internally pulled up to 5volts through a 10k
ohm resistor. This vottage should normally
be pulled down (ofosed oontact to ground)
and released for alarm (opening the
contact). If anormally open contact is
being used, invert this zone when
~miw (ques~s 8&9).
(Jl) Fault Output Select: The radio
fault output relay may be programmed for
either FAIL-SAFE mode (reiay afways
energized) or LOW CURRENT mode (relay
normally de-energized) by seleoting Yes or
Nob programming question 13: FLT REL
ON (Y/N). In addiin, the relay can be set
for either N.O. or N.C. operation (in either
fail-safe or fowcurrent modes) using the JI
jumper. When fail-safe mode is selected,
the relay will change states (and trigger a
d=ier, if oonnected) in tie event of pcrwer
ioss. Note that fail-safe mode increases
the standby ourmt by about 10mA, which
results in lower batterv bsdam time (about
15%) in the event of ~wer loss. Set-the J1
jumper to position Aor position B,
according to the following tabie:
Prog. Oues. 13 J1 Jumper sating
Fauft Relay ON (refay N.0, or N.C.)
(J3) ACPIECP 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.

MOUNTING
5. The 7720 is intended to be mount- to
ahorizontal surface, preferably on a
ailing, or man attic Iooationon top of a
joist when using the supplied wire
antenna. If using the 7720ANT antenna
kit, the 7720 can be mounted to a
wrticai surfaoe such as a wallorbeam.
After determining the best location for
strong radio cornmunioation with the
Master Station network using the FAST
Toot, mwnt the 7720 to ahorizontal or
vertical surface, depending on the
antenna used. Be sure to allow acoess
to the programming port when
mounting.
POWERING UP:
6, After ail wiring is oomplete and the unit
is mounted, apply power to the control
panel, then plug the 7720’s battery
oable into the mnnector next to the
terminal blook. The LEDs will flash
oonseoutively for abrief time to allow
entry into programming mode. If the
7720 has been programmed, the LEDs
will begin to flash acoordhg to their
funotions. If the 7720 has not been
programmed, the LEDs will flash in
unison indefinitely. important: The
pad must be powered before the
battery is plugged in.
