We often see some words on the floor of some large shopping malls, which says that it is forbidden to stand or place shelves under fire-fighting facilities. These signs are to prevent the fire shutter door from falling down in case of fire, so as to prevent unnecessary loss. I believe everyone knows the function of fire shutter doors. Suppose there is a fire in a shopping mall, Jinan rolling shutter door landing can effectively prevent the spread of fire. Previously, some customers asked us how to control the sliding of fire shutter doors. We will give you a satisfactory answer.

一般购物的大型建筑中，大多数济南卷帘门都有自动控制系统。一旦发生火灾，可以自动进行一系列的动作，防火卷帘门会自动下降，隔绝火势。那么防火卷帘门的自动控制系统是如何工作的呢?

In general shopping malls, most of the rolling shutter doors in Jinan have automatic control system. In case of fire, a series of actions can be carried out automatically, and the fire shutter door will automatically drop to isolate the fire. So how does the automatic control system of fire shutter door work?

如果发生火灾，设备顶部的烟雾传感器接收烟雾信号，并向控制系统发出警报。识别后，消防控制系统打开火区防火卷帘的电源，使火区防火卷帘以设定的速度下降到地面。当百叶窗下降到离地面约1.5米的位置时，它间歇地移动，以便于当前人员的分散注意力和疏散。所有相关人员撤离后，防火卷帘将继续下降，直关闭。防火卷帘门的下降速度和停留时间可根据人数进行调整。

In case of fire, the smoke sensor on the top of the equipment first receives the smoke signal and sends an alarm to the control system. After identification, the fire control system turns on the power supply of the fire zone fire shutter to make the fire shutter descend to the ground at a set speed. When the shutter is lowered to about 1.5 meters above the ground, it moves intermittently to facilitate the distraction and evacuation of the current personnel. After all relevant personnel are evacuated, the fire shutter will continue to drop until it is closed. The descending speed and residence time of the fire shutter door can be adjusted according to the number of people in the shopping mall.

当然了物品不能堆放在防火卷帘门下，也不能用作通道。此外，防火卷帘门在控制系统的控制下自动下降，因此无需担心下降控制。

Of course, items can not be stacked under fire shutter doors, nor can they be used as passageways. In addition, the fire shutter door automatically drops under the control of the control system, so there is no need to worry about the descent control.
