1.0 Description
The Detcon AV2-DV2 Alarm Stations are wireless, battery powered alarm stations with a two 5 Joule Strobes
and an 110Db @ 1mtr Horn that can provide one of 16 possible alarm tones. The unit is designed for
installation and use in Hazardous duty, corrosive work environments rated at Class 1, Division 2, Groups E, F,
and G.
Figure 1 Basic C1D2 Wireless Alarm Stations
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 two internal 12V battery
packs. 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(s). 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).
