The Multi-Alert models mount directly to 4″ square back boxes. Optional mounting
plates are available for either flush or semi-flush installations. Model MA12/24D is suitable
for outdoor applications when installed with the WBB weather-proof back box.
Multi-Alert Strobes.
System Sensor’s Multi-Alert strobes are UL1638 compliant
electronic visible warning signals that flash approximately every 1.5 seconds. All
circuits are polarized to be compatible with DC alarm supervision.
Mini-Alert Sounders.
System Sensor’s PA400 series Mini-Alert sounders operate
at 12 and 24 volts and are ideal for hotel, motel or residential fire system
applications, where a smaller notification device is desired. The PA400
sounders are available with or without FIRE identification, and are offered in
red, beige, and white.
