We often see some local signs on the ground in some large shopping malls or shopping malls, which say that under the fire-fighting facilities, people are prevented from standing or shelves are placed. Then, the main function of the equipment fire shutter is that if a local fire occurs in the shopping mall, the extension of the fire can be stopped only by putting down the shutter.
General shopping malls in these large buildings have automatic central control system, once a fire occurs, it can automatically carry out a series of actions, and the fire shutter will automatically lower to isolate the fire. The following is the operation process of the automatic control system of the fire shutter door. In case of a fire, the smoke sensor on the roof of the equipment receives the smoke signal first, and alarms to the central control system together. After identification, the fire control system of the fire center connects the power supply of the fire shutter door in the fire area, so that the fire shutter in the fire area drops to the ground at a certain speed.
When the roller shutter descends to the position about 1.5m above the ground, it will move intermittently to facilitate the dispersion and evacuation of the personnel on site. After all relevant personnel are evacuated, the fire shutter will continue to descend until it is closed. The down speed and center dwell time of the fire shutter door can be adjusted according to the number of people in the store.
The store does not only need these local equipment fire shutter doors, in some staircases, stairways and so on, there will be these fire prevention methods, because the fire is rare after all, some fire prevention equipment is very good use, so it is required to have professional personnel on time for maintenance.
