Product Description P/N: FSAF120A
Description
The Belimo FSAF120A is a heavy-duty, spring-return damper actuator specifically designed for reliable operation in commercial fire and smoke control systems. Operating on a 120 VAC power supply, this robust mechanical drive delivers 133 in-lb of torque to actively position safety dampers during normal conditions. In the event of an electrical power failure or emergency alarm, the unit automatically springs closed to contain smoke and prevent fire spread throughout the building's ventilation network.

Information About FSAF120ABCM-MS/TP
The FSAF120A is a direct-coupled electromechanical device engineered to meet the stringent UL555 and UL555S safety requirements for dynamic fire and smoke dampers. It features a rugged steel housing that protects the internal brushless DC motor and gear train from extreme thermal conditions up to 250 degrees Fahrenheit. HVAC technicians and life safety engineers utilize this actuator to ensure rapid, fail-safe mechanical isolation of critical ductwork during emergency facility evacuations. The unit mounts seamlessly onto standard round or square damper shafts via a universal clamp mechanism, significantly reducing installation time and eliminating the need for complex external linkages.
Key Features:
● Spring-Return Fail-Safe: Automatically drives the attached damper to a secure, predetermined closed position immediately upon electrical power loss.
● High Torque Output: Generates 133 in-lb of rotational force to reliably manipulate large commercial fire and smoke dampers under active pressure.
● 120 VAC Operation: Runs efficiently on standard 120-volt alternating current power, allowing for direct integration into commercial emergency electrical grids.
● High-Temperature Tolerance: Engineered to operate safely and effectively at elevated temperatures up to 250 degrees Fahrenheit during active fire events.
● Direct-Coupled Mounting: Attaches straight to standard round or square damper shafts using a universal clamp, minimizing required hardware.
● Brushless DC Motor: Reduces internal friction and mechanical wear during continuous duty cycles to extend the operational lifespan of the actuator.
● Rugged Steel Enclosure: Features a highly durable outer housing that protects sensitive internal electronics from mechanical shock and extreme heat.
The FSAF120A delivers the reliability and precision required for strict airflow regulation and emergency fail-safe containment in commercial ventilation networks.
