Function of Henan fire door in fire fighting

We often see on the ground of some large places or places that no one is allowed to stand under the fire facilities or there are shelves. Then, the primary use of assembling fire doors is that if a fire occurs in a certain place, the rolling shutter door can stop the extension of the fire when it is put down.

Usually, the fire doors in such large buildings have automatic central control systems. Once a fire occurs, you can automatically implement a series of behaviors, and the fire doors will automatically lower the fire.

The following is the employment process of the automatic control system of the fire door. When a fire occurs, the smoke sensor installed on the roof receives the flag of the smoke and alarms to the central control system. After identification, the control system of the fire center connects the power supply of the fire door in the fire alarm location area, so that the fire shutter in the fire area will fall to the ground at the required rate.

When the roller shutter passes to a position about 1.5 meters above the ground, stop the activity, so as to facilitate the evacuation and evacuation of employees on site. After the associated employees withdraw together, the fire door will continue to go down until it is closed. The descending rate of the fire door and the time of stay during the period can be adjusted according to the number of employees.

It is not only such places that are equipped with fire doors, but also in some staircases, corridors and other places. Since fire is rarely generated and some fire prevention settings are easy to use, the conditions must be inspected regularly by dedicated staff.
