Page 3: System Features & Operation
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.
Page 4: Features
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;...

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.

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.

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.
Page 8 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.

Page 11 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.
Page 12: Programming The 7720Plus
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.
Page 13: Zone Mode Unique Programming
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.

Page 25: Antenna Mounting
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.
Page 26: Standard Wire Antenna
The 7720PLUS must always be mounted indoors. If the only suitable antenna location found is outside of the protected building, mount the 7720PLUS close to this location on the inside of the building and connect an external (outdoor) antenna to the radio. Carefully follow all instructions included in these optional parts to insure integrity of the weather-proof seals on all outside connections.

Use only ADEMCO Cables P/N 7626-5 (5’), 7626-12 (12’), 7626-25HC (25’) or 7626-50HC (50’). 2. Do not attempt to make the antenna cables yourself, and do not under any...
Page 28: Post Installation Checklist
Post Installation Checklist is intended for installers who want to get the 7720PLUS up and running quickly. To take full advantage of the many installation features of the 7720PLUS, we strongly suggest you take a few moments and read the programming section.
Page 29: Testing The7720Plus
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”...
