PRODUCT DETAILS

Fire Damper is a normally-closed damper, which is opened by control center through 24VDC or manually.

It closes automatically at 70℃ or 280°C temperature, and must be reset manually.

Its function is: when the smoke temperature reaches 280 ℃, people have basically been evacuated. At this time, the smoke is already carrying fire and the exhaust has no practical meaning, so the damper is automatically closed to prevent the fire from spreading.
