Information About FSAF120A-S
The FSAF120A-S belongs to Belimo’s FSAF series of fail-safe actuators developed for fire and smoke damper applications. Its spring-return mechanism maintains fail-safe damper positioning when electrical power is interrupted, while the motor drives the damper during normal operation. The actuator supports reversible clockwise or counterclockwise mounting and provides a 95° rotation range with a motor running time of 25 seconds per 90°. Two integrated SPST auxiliary switches provide electrical indication of damper position, with wiring provided through a 4-wire appliance cable and 1/2-inch NPT conduit connector.
Key Features:
- Spring Return: Provides fail-safe damper positioning when power is removed.
- 120 VAC Operation: Designed for AC 120 V power supply applications.
- 180 in-lb Torque: Produces 20 Nm of torque for fire and smoke damper operation.
- On/Off Control: Uses two-position control for straightforward damper actuation.
- Auxiliary Switches: Includes two SPST switches for open and closed position indication.
- 95° Rotation: Provides the required angular movement for damper positioning.
- Fast Fail-Safe Action: Returns to the fail-safe position in less than 15 seconds.
- UL Type 1 Enclosure: Uses a UL Enclosure Type 1 housing for the specified installation environment.
The FSAF120A-S delivers the reliability and precision required for fail-safe fire and smoke damper control in HVAC ventilation systems.
