Belimo FSAFB24-SR Proportional Smoke/Fire Actuator DCA 24V

The Belimo FSAFB24-SR Smoke/Fire Dca 24V Prop. is a spring-return, normally closed fire damper actuator intended for use in HVAC systems. It features a proportional control signal for accurate damper blade positioning and runs on a 24V power source. When a fire occurs, a smoke or fire signal triggers the actuator, which essentially stops smoke and flames from spreading down the ductwork.This product is specifically designed for fire dampers, which are critical components of HVAC systems that play an important role in fire safety. In the case of a fire, the smoke or fire signal causes the Belimo FSAFB24-SR to close the damper blade, isolating the fire zone and preventing the spread of smoke and flames through the HVAC system.
