About the 7720 PLUS
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 telephonebased system, the 7720PLUS is comparable to a digital communicator connected by
telephone line to a central monitoring station.
Installer, please read this Installation and Setup Guide all the way through and become completely
familiar with it before attempting to install a 7720PLUS Synthesized Subscriber Radio.
♦ General Operation
♦ Low Battery Detection and Restoral
System Features
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 each other (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 (refer to Tables 1
and 2). A blinking yellow LED indicates normal operation.

Built-in Tamper Protection
For added protection, built-in cover tamper switches 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 automatically reports the tamper status to the control panel, as well as to
the central station
Antenna
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), or a 7674 (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 using the following pre-assembled coaxial cable available from ADEMCO:
5ft coax (P/N 7626-5), 12ft coax (P/N 7626-12), 25ft coax (P/N 7626-25HC), and 50ft coax (P/N
7626-50HC).
Programmable Features
The 7720PLUS utilizes EEPROM (Electrically Erasable Programmable Read Only Memory)
technology that 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), and
• open/close/restore reporting channels.
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 by an AC wall transformer, part number (1324), which provides
12VAC 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.
Section1. System Features and Operation
Low Battery Monitoring
The 7720PLUS tests its battery under 200mA load approximately every 4 hours. During this
test, the 7720PLUS notifies the central station of a low battery condition if the battery
voltage drops below 9.93V (± 5%). Low battery restore messages are reported during
successive tests if the battery voltage reaches 10.03V (± 5%). During an AC failure condition,
the periodic battery test is not performed, but the battery voltage is tested during each
regular transmission, and a detected low battery condition is transmitted as described. A
radio configured for ECP reports the battery status to the control panel as well as to the
central station (most current controls do not annunciate this condition unless it occurs in
conjunction with a more serious fault).
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 138VAC 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 control panel and converts these
signals to radio messages. These messages 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 4.5-14.2VDC. 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 is
activated when the signal goes to ground. The pull-up voltage for zones 1 and 2 can be
supplied by changing a jumper. Pull-up voltage for any of the zones can be supplied from the
radio through external resistors or from a control panel.)
1-3
7720PLUS Installation and Setup Guide
Upon detecting an alarm or restoral, the 7720PLUS transmits the messages to the master
station network. The transmissions repeat for approximately 6 minutes (total of 60
messages) to ensure that the alarm or other report is received by the central monitoring
station.
The 7720PLUS periodically transmits supervisory status messages to the AlarmNet
network. The supervision period (window) is a programmable feature. If no messages are
received during the supervisory window, the network will generate a communication failure
signal to the central station.
Radio faults that may prevent communication are indicated locally via the Radio Fault LED
(refer to Table 2) and they are reported to the control panel via the fault relay in zone mode
or via the ECP Status message in ECP mode. The fault relay, which is only available in zone
mode, is a contact closure that can be either normally open or normally closed. In addition it
can be selected to be “fail-safe” by programming the fault relay to be “on” (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.
When using ADEMCO's low-end control panels (VISTA-10SE, VISTA-20SE, VIA-30P), the
ECP Status code is displayed on the control panel's keypad as “Long Rnge Fail” followed by a
4-digit code. When using ADEMCO's high-end control panels, a description of the fault is
displayed in conjunction with a “CHECK 8xx” message where “xx” is the ECP address of the
7720PLUS.
Also available only in zone mode 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 Section 5: Testing the
7720PLUS for information regarding the “S” command and status messages.
Low Battery Detection and Restoral
Low Battery Detection
The radio tests the condition of the battery periodically. If the radio finds that the battery is
low, a low battery warning message is transmitted. When the battery voltage restores, the
radio transmits a battery restore message.
The battery is under continuous float charge whenever the AC power is connected and
sufficient.

(J2) Zone Inputs Activate on High or Low
NOTE: See Figure 2 when setting jumpers.
If using zone input connections, set the zone sense select jumper so that zone 1 and 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
and 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 and 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 (Zone Mode Only)
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 fault relay sense
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: 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 J1 to short pins 1-2 or short pins 2-3 as follows:

Wiring at the Control Panel
1. Connect ground wire to the auxiliary power ground on the control panel.
2. Run the alarm wires to the transmitter location.
Wiring for ECP Communication with a Control Panel
Only certain control panels support ECP data communication. Check the Installation and
Setup Guide of your control panel to see if Long Range Radio is supported.
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 control
panel. To wire the radio for ECP communication, do the following:
1. Connect TB1-4 (Ground) of the 7720PLUS to the ground of the control panel.
2. Connect TB1-5 (ECP IN) of the 7720PLUS to “data out to consoles” connection on the
control panel.
3. Connect TB1-6 (ECP OUT) of the 7720PLUS to “data in from consoles” connection on the
control panel.
