PRODUCT DESCRIBE

Fire - resistant roller shutter doors are a kind of modern - day fire - fighting equipment and belong to a type of fire - compartmentation. They are mainly used in the fire - compartmentation of buildings, such as being installed at the openings of fire - walls, in evacuation passages, in elevator halls and other locations. Normally, they are rolled up and stored in the upper space of the building. When a fire breaks out, they can be automatically or manually lowered to form a barrier that can prevent the spread of fire and smoke, buying time for the evacuation of people and fire - fighting operations.

PRODUCT FEATURES

• Fire-resistant roller shutter doors are equipped with two control methods: automatic and manual. The automatic control is achieved by interlocking with the building's fire alarm system. When the fire detector detects a fire signal, the signal will be quickly transmitted to the control box of the fire-resistant roller shutter door, driving the motor to operate and making the roller shutter door descend automatically. Meanwhile, manual chains or buttons are also set on both sides of the door for convenient manual operation in emergency situations (such as when the automatic control system fails), ensuring the normal use of the roller shutter door.

• During the closing process of the fire-resistant roller shutter door, the sealing devices (such as rubber seals) on the edges of the curtain plates will closely fit the guide rails and the ground, forming a relatively closed space and effectively preventing the spread of smoke. Smoke contains a large amount of toxic and harmful gases. Preventing the spread of smoke can provide a more favorable environment for personnel escape and fire rescue, reducing the risk of personnel being poisoned by inhaling smoke.
