Description
The Belimo BF24-TN is a spring return fire damper actuator designed for reliable, fail-safe operation in life-safety HVAC applications. Engineered to automatically drive fire and combination fire/smoke dampers to the closed position upon loss of power or control signal, this actuator plays a critical role in containing the spread of fire and smoke through ductwork systems.
Key Features
- Spring return (SR) fail-safe mechanism — automatically closes damper on power loss
- 24V AC/DC supply voltage for broad system compatibility
- Compact, direct-coupled design for straightforward installation
- Suitable for use with fire dampers and combination fire/smoke dampers
- Designed to meet UL 555 and UL 555S fire and smoke damper actuator standards
- Belimo’s proven direct-coupled technology eliminates the need for crank arms or linkages
- Overload protection built in — actuator is electronically protected against stall conditions
- Manual override capability for commissioning and testing
Application
The BF24-TN is ideal for commercial and industrial HVAC systems where code-compliant fire protection is required. Its spring return action ensures the damper blade returns to the closed (fail-safe) position whenever power is interrupted, making it well-suited for fire-rated wall and floor penetrations, air handling units, and duct distribution systems.
