The Belimo FSNF24 is a 24-volt spring return damper actuator specifically designed for fire and smoke damper applications. This actuator provides 70 lb-in of torque, delivering reliable performance for life safety systems in commercial HVAC installations.

Key Features:

• 24VAC/DC power supply for compatibility with standard control systems
• 70 lb-in (8 Nm) nominal torque for positive damper control
• Spring return operation ensures fail-safe damper closure during power loss or fire emergency
• UL listed for fire and smoke damper service
• Designed for 2-position control applications
• Fast acting mechanism for rapid damper positioning in emergency situations
• Durable construction for long-term reliability in critical life safety systems

This actuator is engineered to meet stringent fire safety codes and is ideal for controlling fire and smoke dampers in stairwells, corridors, and other compartmentalized areas where smoke containment is essential. The spring return mechanism ensures the damper automatically closes to contain smoke and fire when power is interrupted or during an emergency signal.
