System Sensor's Multi-Alert sounder and sounder/strobes are suited to provide primary

or secondary signaling for fire and security applications. The MA and MASS models

provide eight field-selectable warning tones.

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.
