Introduction

The 7835C is the subscriber end of the AlarmNet C reporting system. It is comparable to a digital
communicator, but instead of transmitting signals over the telephone lines, it transmits radio signals to the
central monitoring station using the control channel of the AMPS cellular phone network. This allows
faster and more secure reporting and greater coverage.

The 7835C is compatible with existing installations using ADEMCO equipment or other control panels.  It
can be used in conjunction with digital communicators on the same system to provide redundant reporting.

The 7835C Transceiver uses the control channel of the Advanced Mobile Phone System (AMPS) cellular
network to report subscriber alarms and system status messages.  It operates on either the “A” or “B” side
of the cellular network without using a voice channel.  Because alarms are transmitted only on the control
channel, a true “phone call” is never placed.  This eliminates delays due to busy or saturated cells where no
voice channels are available.

The 7835C is compliant with the MicroBurst standard for packet-based control channel cellular
communication.  Alarm and status packets are transmitted from the subscriber to a local cell where they are
identified and then routed using SS7 to the AlarmNet Control Center.  The AlarmNet Control Center then
logs the alarm and routes it via RF to the appropriate AlarmNet-A or AlarmNet-M equipped central station.

System Features

Hardware Features

 

Up to 6 input zones (when ECP is not used) that can be triggered by either applying or removing a
voltage.

 

Zones 1 and 2 are configurable to trigger on the application of a voltage or ground.

 

Zones 5 and 6 are configurable as voltage-tripped zones or as ECP IN / ECP OUT, respectively  (the
installer must choose either zone inputs or ECP communication, not both).

 

Radio fault relay Form A contacts, programmable.

 

Auxiliary, general purpose relay, Form A contacts, controllable across the radio link.

 

Trigger voltage for use with dry contact relays.

LED Indications

 

Received Signal Strength Indication (RSSI), displayed on a 5-position bar graph.

 

Three radio status LEDS to indicate message status and radio status.

Antenna

 

ADEMCO cellular antenna included (part number K3209).

Power

 

Wall-mounted 16.5VAC / 40VA transformer ADEMCO PN: 1361 (1361CN for Canadian installations).
