SSM24-8

The Honeywell/System Sensor SSM24-8 is a larger 8-inch motor-driven fire alarm bell providing louder resonant tones for indoor/outdoor fire notification compared to the 6" SSM24-6 model.
It maintains the same low current draw and polarized design for NAC circuit supervision, mounting to standard 4" square boxes or WBB weatherproof backbox for outdoor use.
