A fixed or movable smoke barrier made of non combustible materials that hangs from the ceiling by no less than 500 mm. Active smoke barrier refers to a fire hazard
A smoke barrier that automatically hangs down due to temperature, smoke, or other control devices. Mainly used in high-rise buildings or warehouses, it can block smoke
Mist flows horizontally under the building ceiling to improve the smoke exhaust effect in the smoke prevention zone and play a role in protecting life and property.
The sign on the smoke barrier wall should be firm and the identification should be clear.
The surface of the metal components of the smoke barrier should not have cracks, dents, obvious bumps, hammer marks, burrs, holes, etc; Its surface is treated with rust prevention and coated with
The layers and coatings should be uniform, without any peeling or flowing phenomena.
The smoke blocking components of the rolling shutter type smoke barrier should not have tearing, missing corners, digging, holes, tilting, jumpers, broken wires, or significantly uneven warp and weft yarn density
Color difference, etc; Its surface should be straight, clean, and aesthetically pleasing.
The assembly and splicing of each component must not have any misalignment.
The sign on the smoke barrier wall should be firm and the identification should be clear.
The smoke barrier should be linked with the smoke detector. After the smoke detector, the smoke blocking wall can automatically descend to the smoke blocking working position.
After receiving the control signal from the fire control, the smoke barrier should be able to descend to the smoke barrier working position.
When the system is powered off, the smoke barrier can automatically descend to the smoke barrier working position.
The operating speed of the electric or mechanical descent of the rolling shutter smoke barrier should be ≥ 0.07m/s. During the operation of the flip type smoke barrier with electric or mechanical descent
The interval should be less than 7 seconds. The smoke barrier should be equipped with a limit device, which can automatically stop when it runs to the upper and lower limits.
