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.
