General Description

All Series SS24ADAS strobes are suitable for primary

signaling in public mode life safety applications. The

strobes can be connected to the alarm indicating circuit of

a UL listed fire alarm control panel. They are compatible

with DC line supervision. Panels may have full-wave

rectified, unfiltered power supplies. The strobes are

available for 24VDC operation and can be used with the

System Sensor Multi-Alert™ horn. Stand-alone strobe

versions incorporate these “installer easy” features: plug-

in terminal strip, wiring guide, and strip gauge (on back).

Semiflush mounting is available with the addition of an

MP-SF accessory plate. When installed in a zone, the

SS24ADAS and MASS24ADAS Series devices flash

simultaneously. Note: SS24ADAS and MASS24ADAS

Series devices operating in the same zone will not be

synchronized if energized at different times (i.e., if

more than one controller is controlling the same zone).
