Belimo FSAF24-SR Spring Return Fail-Safe, Fire & Smoke Proportional Actuator, 24
The FSAF24-SR-S is used for proportional modulation of UL555S rated dampers in HVAC. Actuator sizing should be done in accordance with the damper manufacturer's specifications.
The FSAF series actuators provide spring return operation. There is no reversing switch on the FSAF24-SR. It is direct acting only. A reverse acting signal is required if it must spring open while 2V signal drives it closed. The torque is asymmetrical giving 180 in-lb drive and 133 in-lb spring.
The actuator may not be mechanically paralleled or "piggybacked." Each damper section should be controlled by a separate actuator. - Belimo - Belimo - FSAF24-SR - FSAF24-SR
