In addition to the functions of quick opening and closing, heat preservation and anti-theft, PVC fast doors in large factories also have a particularly important function, which is fire isolation. PVC fast doors can quickly isolate the fire area when a fire occurs, and effectively control the spread of the fire. Therefore, in addition to factory buildings, many enterprises, units, factories and civil buildings have begun to use PVC fast doors as fire and anti-theft security walls. So how does it accomplish the work of fire isolation?

The PVC fast doors will be placed in the middle of the two fireproof areas inside the building. When a fire occurs in the workshop, one of the fireproof areas will issue a fire safety alarm, and the system will automatically lower the fast rolling door to isolate the two areas. Come to prevent the fire from spreading. Moreover, when the rapid descent of the shutter door is completed, it will also send a signal to the system to tell the relevant personnel to help them judge the actual situation and quickly respond to emergency situations, and evacuate the crowd to a safe area as soon as possible.

PVC fast doors are also often used in evacuation routes, and are often used with temperature sensors and smoke density sensors. Nowadays, there are fast rolling shutters on the escape route. When people pass by, they can automatically detect the temperature and smoke concentration according to the program settings. If they exceed the standard, they will automatically shut down and isolate them, and send the signal to the control center. On-site personnel can judge each section based on the signal It can be said that the PVC fast door has added more hope for the escape of personnel by implementing corresponding emergency measures to complete self-rescue.
