There will be roller shutter doors in many places in the streets and alleys, but many people don't know exactly where the roller shutter doors in Jinan should be installed and where it is reasonable. Let's have a look.

（1）封闭疏散楼梯，通向走道；封闭电梯间，通向前室及前室通向走道的门。

(1) Close the evacuation staircase to the walkway; Close the elevator room, leading to the front room and the door of the front room leading to the walkway.

（2）电缆井、管道井、排烟道、垃圾道等竖向管道井的检查门。

(2) Inspection doors of vertical pipe shafts such as cable shafts, pipe shafts, smoke exhaust ducts and garbage ducts.

（3）划分分区，控制分区建筑面积所设墙和隔墙上的门。当建筑物设置墙或门有困难时，要用卷帘门代替，同时须用水幕保护。

(3) Divide zones and control the doors on the walls and partitions set up in the building area of the zones. When it is difficult to set walls or doors in buildings, rolling shutter doors shall be used instead, and water curtain shall be used for protection.

（4）主要用于大型（大卖场）、大型、大型材料市场、大型展馆、厂房、仓库等有消防要求的公共场所。当火警发生时，卷帘门在消防控制系统的控制下，按预先设定的程序自动放下（下行），从而达到阻止火焰向其他范围蔓延的作用，为实施消防灭火争取宝贵的时间。

(4) It is mainly used in large supermarkets (hypermarkets), large shopping malls, large professional material markets, large exhibition halls, workshops, warehouses and other public places with fire protection requirements. When a fire alarm occurs, the rolling shutter door will be automatically lowered (down) according to the preset procedure under the control of the central fire control system, so as to prevent the spread of fire to other areas and buy valuable time for the implementation of fire fighting.

在某些场合，建筑内不配备消防控制系统，卷帘门仅借助于卷帘门的消防控制电器箱实现卷帘门的规定运行程序。在这种情况下，当火警发生时，烟雾传感器接收的火警信号直接传卷帘门的消防控制电器箱。在停电的情况下，只能通过拉动铁链将卷帘门放下。卷帘门配备的手动，只能单向放下，不能提升。

In some cases, the building is not equipped with a fire control central control system, and the rolling shutter door only uses the fire control electrical box of the rolling shutter door to realize the specified operation procedure of the rolling shutter door. In this case, when a fire alarm occurs, the fire alarm signal received by the smoke sensor is directly transmitted to the fire control electrical box of the rolling shutter door. In case of power failure, the roller shutter door can only be lowered by pulling the iron chain. The roller shutter door is equipped with manual operation, which can only be lowered in one direction and cannot be lifted.
