In commercial buildings and large shopping malls, fire-resistant rolling shutter doors are indispensable fire protection facilities, mainly used to isolate larger spaces into fire zones, effectively separating areas on each floor. Fire resistant rolling shutter doors not only can be used as ordinary doors, but also have special functions such as fire prevention, smoke isolation, preventing fire spread, and protecting personnel evacuation. The manufacturer of the rolling shutter door will organize the requirements for the separation and control of the fireproof rolling shutter door for you. Let's talk about it slowly as follows.
Set up on the electric control box of the fireproof rolling shutter door according to on-site needs
In high-rise buildings, the selection and layout of the effective fire separation area of the super fire curtain becomes the key to whether the super fire curtain can achieve its effective fire prevention function.
Avoid affecting daily life by connecting the upper and lower floors as a fire zone
A balance needs to be struck between not affecting normal life and effective fire isolation. Generally speaking, high-rise buildings are equipped with openings such as up and down connecting corridors, open stairs, escalators, conveyor belts, etc. The upper and lower floors should be connected to form a fire zone, and the large building area allowed by hard and fast rolling shutter doors should not exceed the fire zone building area specified by their building grade.
When the upper and lower openings are equipped with isolation facilities such as fire curtains or water curtains with a fire resistance limit greater than 3.00 hours, the area shall not be calculated by superposition. The lobby, passage, and rolling shutter doors connecting the room and atrium should be separated by Class B fire doors or fire resistant rolling shutter doors with a fire resistance limit greater than 3.00 hours.
From this, it can be seen that the manufacturer of fire resistant rolling shutter doors suggests that the space setting of fire resistant rolling shutter doors requires certain knowledge and cannot be designed and installed casually. The quality of setting up a fire zone directly affects the safety of people's lives and property.
