Belimo FSLF120-S On/Off Spring Return Fire & Smoke Actuator 30 lb-In 120V

The Belimo FSLF120-S Fire/Smoke 120V;35S/R; On or Off is a crucial safety component specifically developed for HVAC systems. When smoke or fire is detected, this spring-loaded fire damper actuator automatically closes fire dampers. During regular operation, the damper remains open due to the 120V AC power source. The spring return mechanism makes sure that the damper snaps shut in the event of a power outage, preventing the spread of smoke and fire. For monitoring and control reasons, it also sends out feedback signals indicating its operational status open or closed and power condition running or stopped. The Belimo FSLF120-S enables to limit smoke and fire within a predetermined area by ensuring that fire dampers are properly closed, thereby protecting building occupants and minimizing property damage.
