Belimo FSAF120A-S Actuator

Belimo FSAF120A-S Actuator

The Belimo FSAF120A-S is a high-torque, fire and smoke damper actuator engineered for life safety applications requiring 180 in-lb of torque. Operating on 120V AC, this spring-return unit ensures fail-safe positioning during power loss or smoke detection events. Built with a rugged NEMA 2 rated housing, it thrives in demanding HVAC environments while maintaining precise control. The integrated auxiliary switches provide definitive end-stop verification for system monitoring. Designed for direct mounting on damper shafts, the FSAF120A-S simplifies installation in UL555 and UL555S rated assemblies. This On/Off actuator delivers reliable two-position operation, making it a critical component for smoke control systems. By utilizing a mechanical spring to return the damper to its safety position, it prevents the migration of smoke through ductwork. Technicians appreciate the standardized Belimo clamp design, which facilitates rapid field replacement and long-term mechanical stability in commercial air handling systems.

  • 180 in-lb Torque Output: Provides ample power for large-scale multi-blade fire and smoke dampers.
  • Integrated Auxiliary Switches: Two built-in SPST switches offer remote feedback for open/closed status verification.
  • Standardized 120V Operation: Eliminates the need for step-down transformers in high-voltage control circuits.
  • UL555S Compliance: Engineered specifically to meet stringent building codes for smoke compartmentation.
  • Mechanical Spring Return: Guarantees a reliable fail-safe cycle to the original position upon power interruption.

Common Questions

What is the typical run time for the FSAF120A-S?
Under normal operation, the drive time is less than 75 seconds, while the spring-return timing is typically less than 20 seconds to comply with smoke safety standards.

Can the FSAF120A-S be used in outdoor applications?
While rated NEMA 2, any exposure to moisture or extreme debris requires a proper weather shield to maintain terminal integrity.

Which shaft sizes are compatible with the universal clamp?
This actuator is designed to fit 1/2" to 1.05" round shafts or 1/2" to 3/4" square shafts commonly found on commercial dampers.
