Information About FSNF120-S US
The FSNF120-S US is part of Belimo’s fire and smoke actuator lineup engineered to meet stringent life safety and code compliance requirements. It features a grounded metal housing and electronic overload protection to ensure reliable operation during normal conditions and emergency events. The actuator is rated to deliver its full 8 Nm torque at elevated temperatures up to 350°F for 30 minutes, supporting critical fire and smoke control functions. Reversible mounting for both motor and fail-safe direction, along with integrated auxiliary switches, enables flexible installation and dependable system integration.
Key Features
- Fire And Smoke Safety Design: Engineered specifically for fire and smoke dampers to support life safety operation and code compliance in HVAC systems.
- Spring Return Fail-Safe Operation: Integrated spring mechanism drives the damper to its safety position immediately upon power loss or emergency shutdown.
- High Temperature Torque Rating: Delivers 70 in-lb of torque at temperatures up to 350°F for 30 minutes, ensuring reliable operation during fire conditions.
- Dual Auxiliary Switches: Includes two SPDT switches for precise position indication, system interlocking, and safety monitoring.
- Fast Actuation Speed: Motor and fail-safe return operate in under 15 seconds to ensure rapid damper response.
- Electronic Overload Protection: Protects the actuator across the full 0…95° rotation range from mechanical overload or obstruction.
- Robust Grounded Housing: NEMA 1 metal enclosure provides durability and electrical safety for 120 V installations.
The FSNF120-S US delivers the reliability and precision required for dependable fire and smoke damper control in life safety HVAC systems.
