Information About FSNF24-S US
The FSNF24-S US is part of Belimo’s FSNF fire and smoke actuator range. Its mounting orientation determines the powered and spring-return directions. A galvanized steel housing encloses permanently lubricated steel gears, while mechanical indication shows actuator position. Separate power and auxiliary-switch cables provide the electrical connections.
Key Features:
- On/Off Control: Operates the connected damper between its commanded and spring-return positions.
- Rated Torque: Provides 70 lb-in (8 N·m) for compatible damper assemblies.
- Rapid Powered Travel: Provides a specified motor running time of 15 seconds per 90°.
- Mechanical Spring Return: Returns the damper in less than 15 seconds after power removal.
- Dual Auxiliary Switches: Includes two SPDT contacts with switching points at 10° and 85°.
- Reversible Mounting: Supports clockwise or counterclockwise operation according to installation orientation.
- Low-Voltage Supply: Operates from nominal 24 VAC or 24 VDC power.
- Indoor Enclosure: Features NEMA 1 and UL Enclosure Type 1 protection.
The FSNF24-S US delivers the reliability and precision required for rapid positioning and spring-return operation of compatible fire and smoke dampers.
