Fire damper
Product Overview:
The fire damper is a normally-closed valve, which is opened by the control center through 24V direct current or manually. It will automatically close at 280°C and must be reset manually. Its function is: when the flue gas temperature reaches 280°C, people have basically been evacuated, and exhausting smoke has no practical meaning, and the flue gas is already carrying fire at this time, and the valve is automatically closed to prevent the fire from spreading. The exhaust air outlet of the system can also be a normally-closed fire exhaust outlet, eliminating the smoke exhaust fire damper on the branch pipe. In case of fire, the air outlet is opened by 24V direct current from the control center or opened manually. When the smoke temperature reaches 280℃, it will automatically close, and reset must also be done manually. The entrance of the smoke exhaust fan room should also be installed with a smoke exhaust fire damper to spread to the floor where the fan room is located with fire potential.
