Belimo FSAF24A Actuator
The Belimo FSAF24A Actuator is a heavy-duty, spring-return solution specifically designed for UL555 and UL555S listed fire and smoke dampers. Built to withstand extreme conditions, this 24V AC/DC actuator delivers a robust 180 in-lb torque rating, ensuring reliable fail-safe operation in life-safety ventilation systems. Engineered with a cold-weld shaft clamp, the Belimo FSAF24A provides a high-strength connection that prevents slippage on both solid and hollow shafts while avoiding tube deformation. This on/off mechanical actuator features a motor drive time of 25 seconds and a rapid spring-return fail-safe response of less than 15 seconds. Rated for exposure to temperatures up to 350°F for 30 minutes, it meets strict HVAC life safety codes. The electronic overload protection eliminates the need for limit switches, while the maintenance-free design and NEMA 1 housing ensure long-term performance in demanding commercial air plenum applications.
Key Benefits- High-Torque Performance: Provides 180 in-lb of torque to ensure a positive seal and reliable close-off for dampers up to 16 sq. ft.
- Life Safety Compliance: Specifically tested to meet UL555S requirements and rated for 350°F operation for critical smoke control scenarios.
- Advanced Shaft Mounting: Utilizes a universal cold-weld clamp that secures to 1/2" up to 1.05" shafts without over-tightening or crushing.
- Parallel Integration: Optimized for parallel wiring on larger damper sections, drawing a consistent 32 VA during operation.
- Fail-Safe Reliability: The mechanical spring-return system provides constant torque even during a total loss of power.
What is the proper transformer sizing for the FSAF24A?
This 24V actuator requires 40 VA for wire sizing. While multiple units can be wired in parallel, always account for the 30A inrush current and use a 2A slow-blow fuse per unit to prevent nuisance tripping.
Can the direction of the fail-safe rotation be changed?
Yes, the direction of motion is selectable by simply flipping the actuator on the damper shaft for CW or CCW mounting, providing flexibility for diverse installation requirements.
Is this model compatible with older FSAF series dampers?
The FSAF24A uses the classic AF frame footprint, making it a direct retrofit for many older installations. However, ensure you use the KH-AFB crank arm if switching from the legacy spline to the new generation interface.
