Belimo BF24-TN Actuator
The Belimo BF24-TN is a heavy-duty fire damper actuator designed specifically for smoke and fire protection systems in commercial HVAC applications. Operating on 24V AC/DC, this spring return actuator provides a reliable fail-safe position upon power loss or thermal trip. With a robust 160 in-lb torque capacity, it is engineered to drive dampers up to certain sizes even under high pressure. The unit features integrated auxiliary switches for precise position feedback to the building automation system (BAS). Built to withstand extreme conditions, it meets UL 555 and UL 555S requirements, ensuring high-temperature resistance and reliable operation during emergency smoke control sequences. The mechanical interface utilizes a standard square shaft clamp for direct mounting, reducing installation time for contractors. This motorized fire damper actuator is the industry standard for maintaining life safety dampers in critical infrastructure.
Key Benefits- Fast Fail-Safe Response: Proven spring-return mechanism ensures dampers close immediately upon power interruption or thermal link activation.
- High Torque Rating: Delivers 160 in-lb (18 Nm) to handle large multi-blade fire and smoke dampers without binding.
- Integrated Feedback: Two built-in auxiliary switches simplify wiring and provide remote verification of open/closed status.
- Thermal Protection: Includes the BAE72 thermal enclosure to ensure functionality during high-heat fire events.
- Standard Compatibility: Universal mounting design facilitates straightforward retrofitting of legacy fire damper actuators.
What is the difference between the BF24-TN and the BLF series?
The BF series offers significantly higher torque (160 in-lb) compared to the BLF series, making the BF24-TN the correct choice for larger dampers requiring more force to overcome air pressure or friction.
Can I use this actuator with 120V power?
No, the BF24-TN is strictly a 24V AC/DC component. For 120V applications, you must use the BF120 model or a dedicated step-down transformer.
Is the thermal trip included with the BF24-TN?
Yes, the "TN" designation typically indicates the inclusion of the thermal enclosure and sensor required for UL-compliant fire damper operation.
