Smoke shutter
At present, smoke detectors are installed in the public spaces of all elevators. When smoke is detected, the fire-fighting linkage system will be activated. If at this time there are smoke-shielding rolling doors at the entrances of the elevators and around the escalators, they will be lowered when the fire-fighting linkage system is activated to cover the smoke and prevent the smoke from spreading to all spaces on each floor.
The shutter of the smoke-shielding rolling door is made of special chemical fiber material, which has good smoke-shielding performance in the event of a fire to avoid the chimney effect, but it does not have any fire prevention and heat resistance aging.
