FSAFB24-SR-S Belimo - 180 iN-LB Fire and Smoke Modulating Spring Return Actuators – 24 Volt
Fire and smoke actuator, spring return, 250°F - For proportional modulation of UL555S rated dampers in HVAC. The actuator operates in response to a 2 to 10 VDC, or with the addition of a 500Ù resistor, a 4 to 20 mA control input from an electronic controller or positioner. A 2 to 10 VDC feedback signal is provided for position indication or master slave applications. The FSAF series actuators provide true spring return operation for reliable fail-safe application and positive close-off on UL555S dampers.
