Belimo FSNF24-FC 24V Fire/Smoke Damper Actuator 70 in-lb Torque

The Belimo FSNF24-FC is a 24-volt spring return fire and smoke damper actuator designed for controlling dampers in life safety applications. This actuator provides 70 in-lb (8 Nm) of torque, making it suitable for dampers requiring reliable fail-safe operation during fire or smoke detection events.

Key Features:

• 24 VAC/DC operating voltage for flexible installation
• 70 in-lb nominal torque for positive damper positioning
• Two-position control (open/closed) for fire and smoke damper applications
• Spring return mechanism ensures fail-safe damper closure on power loss
• FlexConnector terminal design for simplified wiring and installation
• UL listed for fire and smoke damper service
• Compact design with manual override for testing and maintenance
• Position indication for visual verification of damper status

This actuator is ideal for HVAC systems requiring code-compliant fire and smoke protection, automatically closing dampers to prevent the spread of smoke and fire through ductwork. The spring return design provides reliable fail-safe operation, while the FlexConnector terminal system reduces installation time and potential wiring errors.
