1. Open type fire smoke damper
The open type fire smoke damper will automatically fuse when the temperature of flue gas reaches 280℃ and release an electric signal. It is most often used in the intersection of smoke vents and firewall, and a smoke exhaust fan can be connected in order to shut down using the open type fire smoke damper.
2. Closed type fire smoke damper
The closed type fire smoke damper will automatically fuse when the temperature of flue gas reaches 280℃, though clients can also shut it down manually. This smoke damper is typically used in a smoke exhaust system, and is installed at the suction inlet of the smoke exhaust fan, as well as controlled by the fire protection control room during a fire. The smoke exhaust fan will also close when the fire smoke damper is closed.
