Information About FSAFB24-SR-S
The FSAFB24-SR-S is a Belimo fire and smoke actuator designed for modulating control of compatible damper assemblies. Its spring-return construction provides fail-safe operation, while the motor and fail-safe direction can be configured through CW or CCW mounting orientation. The actuator incorporates two SPDT auxiliary switches for position indication and auxiliary control functions. A 95° rotation range, manual hex-crank override, IP54 protection, and NEMA 2 enclosure support installation in commercial HVAC fire and smoke control systems.
Key Features:
- 180 in-lb Torque: Delivers 20 Nm of torque for operating compatible fire and smoke damper assemblies.
- Modulating Control: Accepts a 2–10 VDC control signal for proportional damper positioning.
- Spring Return Operation: Provides automatic fail-safe damper positioning when actuator power is interrupted.
- 24 VAC/DC Power: Supports both AC and DC 24 V power sources for flexible control system integration.
- Dual SPDT Switches: Includes two auxiliary SPDT switches for position indication and control functions.
- Reversible Installation: Motor and fail-safe rotation direction can be configured through CW or CCW mounting.
- Manual Override: Includes a 5 mm hex crank for manual actuator positioning during installation or service.
- IP54 Protection: NEMA 2 enclosure provides protection suitable for compatible indoor HVAC installations.
The FSAFB24-SR-S delivers the reliability and precision required for modulating fire and smoke damper control in HVAC life-safety systems.
