1.0 Description
The Detcon SW-AV1-DV1 Alarm Stations are wireless, battery powered alarm stations with a 5 Joule Strobe
and an 110Db @ 1mtr Horn. The SW-AV1-DV1 uses a Horn/Strobe Combo Alarm. The units are designed
for installation and use in hazardous duty, corrosive work environments rated at Class 1, Division 1, Groups C
and D.
Figure 1 Basic C1D1 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 cables.
The alarm station is powered by an 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).
