FSLF24-FC
The Belimo FSLF24-FC Fire/Smoke Actuator is used to detect fire or smoke in HVAC systems. Powered by 24V supply, it has a spring return mechanism that ensures the closure of dampers in the event of power failure, containing smoke and fire. It has an on/off control type and a 3/8” flex connector for easy connection to HVAC ductwork to make it easy for installation. This actuator improves fire protection by closing dampers when smoke or fire is sensed in the building. This enhances the general reliability of the system and minimizes possible time losses due to fire-related mishaps.
