The SST S270 Intrinsically Safe Photoelectric Smoke Detectors are used in hazardous locations where explosive levels of gas or vapors are normally or potentially present. The SST S270 circuit power levels are limited so the potential to ignite an explosive atmosphere is eliminated.
The SST S270 must be compatible with the system control panel for proper use. An intrinsically safe barrier must be installed at the point where the intrinsically safe circuit connects to the fire alarm control panel. When the SST S270 senses a fire, it latches into alarm and remains in this condition until reset from the NOVA-5000 System control panel.
