Belimo FSTF24-S Actuator

The Belimo FSTF24-S Actuator is a dedicated fire and smoke damper actuator designed for reliable fail-safe operation in life safety applications. Operating on a 24V AC/DC power supply, this spring return actuator provides 18 in-lb of torque, ensuring positive seal-off of dampers during emergency power loss or smoke detection events. Built for the rigorous demands of UL555 and UL555S standards, the FSTF24-S features integrated auxiliary switches for precise position feedback to the building's fire alarm or automation system. Its compact footprint allows for installation in tight mechanical headers where standard actuators won't fit. Experienced HVAC technicians rely on this on/off control motor for its high-temperature durability and consistent cycle performance in critical containment zones. Whether replacing a failed unit or performing a new fit-out, this direct-coupled actuator minimizes installation time with its robust mounting hardware and electrical connections.

  • Torque Output: Delivers 18 in-lb (2 Nm) for consistent damper sealing.
  • Integrated Feedback: Two built-in auxiliary switches provide remote status monitoring.
  • Fail-Safe Reliability: Mechanical spring return ensures immediate closure during power interruption.
  • Life Safety Rated: Specifically engineered and tested for smoke and fire damper applications (UL2043 compliant).
  • Low Power Consumption: Optimized 24V motor reduces total load on the secondary transformer circuit.

Common Questions

What is the typical run time for the FSTF24-S?
The motor drive typically opens the damper in less than 75 seconds, while the spring return fail-safe closes the damper in less than 25 seconds at ambient temperature.

Can this actuator be used in variable air volume (VAV) systems?
The FSTF24-S is an on/off actuator designed for safety containment; it is not intended for modulating dampers or standard air flow control.

How do I verify the auxiliary switch settings?
The switches are fixed at 10 degrees and 80 degrees to indicate full open and full closed positions, allowing for easy integration with fire safety control panels.
