Product Description

 

The fire damper is usually installed on the ventilation pipe. The damper is normally open and it will be closed when the air temperature reaches 70 °C.

Smoke exhaust fire damper is generally installed on the air duct of the smoke exhaust system. It is normally open. When a fire occurs, the smoke detector emits a fire alarm signal. The control center uses the DC24V signal to exhaust smoke. When the flue temperature reaches 280 °C, it will shut down automatically.

The smoke exhaust damper is generally installed on the air duct of the smoke exhaust system. It is normally closed. When a fire occurs, the smoke detector sends a fire alarm signal. The control center sends an electric signal to the solenoid on the damper to open the damper quickly, or manually open the damper quickly for smoke exhaust.
