SSM/SSV Series Alarm Bells System Sensor’s SSM and SSV series bells are low current, high decibel notification appliances for use in fire and burglary systems or other signaling applications. Features Reliable Performance. The SSM and SSV series provide loud resonant tones. The SSM series operates on 24VDC and are motor driven, while the SSV series operates on 120VAC utilizing a vibrating mechanism. • Approved for indoor and outdoor use • Low current draw • High dB output Simplified Installation. For indoor use, the SSM and SSV series mount to a standard four-inch square electrical box. For outdoor applications, weatherproof back box, model number WBB, is used. • Available in six-inch, eight-inch, and ten-inch sizes • AC and DC models • DC models polarized for use with supervision circuitry • Mount directly to standard four-inch square electrical box indoors • SSM and SSV series pre-wired Agency Listings S4011 CS549 3005255 7135-1653:125 7135-1653:100 331-01-E The SSM and SSV series come pre-wired, to reduce installation time. The SSM series incorporates a polarized electrical design for use with supervision circuitry.
