Description
The Belimo FSNF120-S-FC is a 120V spring return fire and smoke damper actuator engineered for life-safety applications in commercial and industrial HVAC systems. Designed to meet the stringent demands of fire/smoke control, this actuator delivers reliable ON/OFF operation with a fail-safe spring return mechanism that drives the damper to its safety position upon loss of power.
Key Features
- 120V AC supply voltage for broad compatibility with commercial HVAC electrical systems
- Spring return (S/R) fail-safe design — automatically returns damper to the safe position on power loss
- ON/OFF control signal for straightforward integration with fire alarm and building automation systems
- Engineered for fire and smoke damper applications requiring UL 555 and UL 555S compliance
- Compact, direct-coupled design eliminates the need for crank arms, levers, or linkages
- Rugged construction suitable for demanding life-safety environments
- Manual override capability for commissioning and maintenance
- Visual position indicator for quick on-site verification of damper status
Application
The FSNF120-S-FC is purpose-built for use on fire dampers, smoke dampers, and combination fire/smoke dampers in commercial buildings, hospitals, schools, and other facilities where life-safety code compliance is critical. The spring return mechanism ensures the damper moves to its fail-safe position — open or closed as required — whenever power is interrupted, providing dependable protection in emergency scenarios.
