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 telephone-
based 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.

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.

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.
