Belimo FSLF24-SFC Actuator
The Belimo FSLF24-SFC is a specialized fire and smoke damper actuator designed for use in life safety applications requiring UL 555 and UL 555S compliance. Operating on a 24V AC/DC power supply, this spring return actuator delivers 30 in-lb of torque, ensuring high-reliability fail-safe operation during power loss or fire alarm triggers. The FSLF24-SFC features a fast-acting 15-second drive time and includes integrated auxiliary switches for remote position feedback, which is critical for verifying damper status in complex smoke control systems. Built with a rugged steel housing, it mounts directly to square damper shafts up to 1/2 inch, making it a standard replacement for underpowered or failing OEM units. This unit is optimized for HVAC fire safety applications where consistency and durability are non-negotiable for building code adherence.
- Spring Return Fail-Safe: Mechanical spring return ensures 100% damper closure during power interruptions or smoke detection events.
- Integrated Auxiliary Switches: Two internal SPDT switches allow for precise monitoring of open and closed positions without external mounting.
- UL 555S Rated: Specifically engineered to meet rigorous standards for smoke and heat protection in commercial ventilation systems.
- Low Power Consumption: Efficient 24V motor reduces demand on the transformer while maintaining high holding torque.
- Compact Form Factor: Designed for tight installations within plenum spaces and narrow damper frames.
Common Questions
How do I wire the FSLF24-SFC for fire alarm integration?
Standard wiring involves connecting the 24V supply through a heat-responsive device (like a BAE165) or a smoke detector relay to the actuator leads, ensuring the unit fails closed when power is cut.
Can the FSLF24-SFC replace an older FSLF24-S model?
Yes, the 'S' suffix indicates the inclusion of auxiliary switches, making this an upgrade or direct replacement for the standard FSLF24 model if monitoring is required.
What damper shaft sizes are compatible with this actuator?
The universal clamp is designed for 3/8-inch to 1/2-inch square or round shafts typically found in multi-blade smoke dampers.
