7835C Cellular Control Channel Transceiver
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.
