Information About BF24-TN
The BF24-TN is a fire damper actuator from Belimo engineered specifically for safety-related air control applications where dependable fail-safe performance is required. It features a robust electromechanical design with integrated spring return, supporting precise damper actuation under normal operation and automatic positioning during power interruption. The BF24-TN supports AC/DC 24 V control and includes dual auxiliary switches for position feedback and system interlocking. Its compact form factor, halogen-free cabling, and selectable mounting direction allow integration into a wide range of fire and smoke damper assemblies in commercial and industrial HVAC installations.
Key Features
- Spring-Return Fail-Safe Operation: Provides automatic damper movement to the safety position during power loss using a high-reliability spring mechanism.
- AC/DC 24 V Control Power: Supports standard low-voltage HVAC control systems with stable operation across a wide voltage tolerance range.
- High Torque Output: Delivers 18 Nm motor torque and 12 Nm fail-safe torque to ensure dependable damper positioning under load.
- Dual Auxiliary Switches: Equipped with 2x SPDT switches for precise position indication and integration with monitoring or control systems.
- Manual Override Capability: Includes a manual override with position stop to allow commissioning, testing, or maintenance without power.
- Quiet and Efficient Operation: Maintains low sound power levels during both motor-driven and fail-safe operation.
- Long Service Life: Designed for a minimum of 60,000 safety cycles to support long-term operation in critical environments.
The BF24-TN delivers the reliability and precision required for fire and smoke damper actuation in safety-critical HVAC systems.
