AlarmNet-C

Control Channel Cellular

AlarmNet-C is an AlarmNet service that operates over the control channel of the cellular telephone network (in conjunction with MicroBurst technology provided by Aeris Communications). The control channel has the same coverage as the analog cellular networks, but uses full power, has very little traffic, and no system busy conditions. There are no monthly cellular charges incurred, and no cellular phone call is required. Radios using the AlarmNet-C network can report into central stations equipped with AlarmNet-A or AlarmNet-M receivers using existing equipment. The transmitter has six zones and an on-board signal strength meter for easy installation.

How does it work?

At the customer premises, the AlarmNet-C radio cellular transceiver is hardwired to the control panel. In the event of an alarm, the AlarmNet-C radio transmits a signal to the cellular network on its control channel. The actual transmission is accomplished using the same technology that enables any cellular phone to make calls from outside their local areas. The AlarmNet-C radio links to the control channel network as if it were a regular cell phone, but it is capable of sending alarm data in place of the destination (called) telephone number. The cellular network then forwards the packet to the AlarmNet NCC, where it is sent through another network to the appropriate central station (AlarmNet-C networks are presently used only to receive, and not to send alarm messages.) Subscribers are fully supervised, and there is only a low fixed monthly charge for normal traffic.
