Description
The Belimo FSNF120-FC is a 120V, 2-position fire and smoke damper actuator engineered for life-safety applications in commercial and industrial HVAC systems. Designed to meet the rigorous demands of fire/smoke control, this actuator provides dependable, code-compliant operation for fire/smoke combination dampers and smoke dampers in air distribution systems.
Key Features
- 120V AC supply voltage for straightforward integration with standard building electrical systems
- 2-position (open/close) control for reliable fire and smoke damper actuation
- Fail-safe spring-return mechanism ensures the damper moves to its safe position upon loss of power
- Compact, direct-coupled design eliminates the need for crank arms or linkages, simplifying installation
- UL 555 and UL 555S listed for use on fire dampers, smoke dampers, and combination fire/smoke dampers
- Built-in auxiliary switch provides end-position feedback for building automation and fire alarm system integration
- Rugged housing suitable for demanding mechanical room and air-handling unit environments
- Manual override function allows damper positioning during commissioning and maintenance
Application
The FSNF120-FC is ideal for use in air handling units, fan coil units, and ductwork where fire and smoke control is required by code. Its 2-position spring-return operation ensures that in the event of a power failure or fire alarm signal, the damper automatically moves to the fail-safe closed position, helping to contain smoke and fire spread throughout a building.
