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.
