Fire Damper

1. The fire damper is typically installed in ventilation ducts. The damper is normally open, and closes when the air temperature reaches 70°C.

2. When the temperature reaches 70°C, the thermal fuse activates, and the damper closes by the force of a tension spring.

3. Electric closure, manual closure, and manual reset are available.

4. After the damper closes, an electrical signal can be sent to interlock the corresponding fan.
