Information About FSNF120 US
The FSNF120 US is part of Belimo’s certified fire and smoke actuator series developed specifically for life-safety HVAC applications. It is engineered to operate reliably under elevated temperatures and emergency conditions, ensuring proper damper positioning during fire or smoke events. The actuator uses a spring return mechanism to drive the damper to its safety position upon power loss, meeting stringent code and regulatory requirements. Designed for maintenance-free service, it integrates robust electrical protection and proven mechanical components for long-term reliability.
Key Features
- Life-Safety Rated Fire And Smoke Actuation: Designed and tested to deliver 70 in-lb of torque at temperatures up to 350°F, ensuring reliable damper operation during fire conditions.
- Spring Return Fail-Safe Operation: Automatically drives the damper to its designated safety position upon power loss, supporting critical smoke containment strategies.
- Fast Response Time: Achieves full 90° rotation in approximately 15 seconds for both normal and fail-safe operation, enabling rapid system response.
- Robust Electrical Design: Operates on 120 VAC power with grounded housing and electronic overload protection for safe and stable performance.
- Flexible Installation Orientation: Direction of motion and fail-safe action can be configured through CW/CCW mounting to suit damper requirements.
- Integrated Position Indication: Mechanical position indicator provides clear visual confirmation of damper status during inspection and commissioning.
- Code And Standard Compliance: UL listed, UL 2043 compliant, and approved for use in air plenums and fire-rated HVAC systems.
The FSNF120 US delivers the reliability and precision required for fire and smoke damper control in commercial and institutional HVAC life-safety systems.
