The alarm station can be positioned almost anywhere, since the wireless ability of the unit means that there is
no need for running conduit or outside connections. The alarm station is powered by its internal 12V battery
pack. Communication is performed via the Detcon RXT-300 or RXT-320 series of transceivers. Access to the
unit is only necessary for battery maintenance or exchange. With the addition of a solar panel, access can be
kept to periodic functional tests and checks.
Internal wiring between components runs through the Wireless Alarm Interconnect PCA. This PCA controls
the state of the alarms via communication with the Wireless Transceiver. When an alarm is triggered, the
wireless transceiver will provide the interconnect PCA with the signal(s) necessary to activate the proper
alarm(s).
