NOTIFIER Alarm bells deliver high sound pressure output for fire signaling needs. Models are available for 120VAC and 24VDC operating voltages and are offered in 6, 8, and 10-inch sizes.
SSM Series alarm bells are low-current, high-decibel notification appliances for use in fire and burglary systems or other signaling applications. They come pre-wired to reduce installation time, and also incorporate a polarized electrical design for use with supervision circuitry.
With reliable performance, SSM Series alarm bells provide loud, resonant tones. They operate on 24 VDC and are motor driven. SSM Series alarm bells offer simplified installation. For indoor use, SSM Series alarm bells mount to a standard 4″ (10.16 cm) square electrical box. For outdoor applications, a WBB weatherproof backbox is used.
