Smoke Alarm
The GS671 is an advanced conventional photoelectric smoke detector engineered specifically for commercial applications. Built to meet the stringent requirements of the upcoming UL 268 8th Edition standard, it features a highly stable sensing chamber that requires no adjustment or replacement. Designed to distinguish between fast-moving fires and smoldering polyurethane foam fires, it delivers an optimized reduction in nuisance alarms—especially during cooking events—while enhancing reaction time to real, life-threatening fires.
