防火卷帘门一般在什么地方设置

依据工艺决定的，防火卷帘门除设置在防火墙外，在两个防火分区之间没有防火墙的也应设置防火卷帘。一般设在以下部位:

According to the process, in addition to the firewall, the fire shutter door should also be set if there is no firewall between the two fire compartments. It is generally located in the following parts:

（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 stairs to the walkway; Close the elevator room, the door leading to the front room and the door leading to the aisle.

（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 cable shaft, pipe shaft, smoke exhaust duct, garbage duct and other vertical pipe shafts.

（3）划分防火分区，控制分区建筑面积所设防火墙和防火隔墙上的门。当建筑物设置防火墙或防火门有困难时，要用防火卷帘门代替，同时须用水幕保护。

(3) Divide the fire compartment, control the building area of the partition, and set the firewall and the door on the fire partition. When it is difficult to set firewalls or fire doors in buildings, fire shutter doors should be used instead, and water curtain protection should be used at the same time.

济南防火卷帘门安装维修厂家认为在通常情况下，大型建筑根据国家消防法的规定配置了消防中央控制系统。当火灾发生时，安装在房顶的烟感传感器（简称烟感）先接到烟雾信号，同时向中央控制系统报警。

Jinan fire shutter door installation and maintenance manufacturers believe that under normal circumstances, large buildings are equipped with a central fire control system according to the provisions of the national fire protection law. When a fire occurs, the smoke sensor installed on the roof (hereinafter referred to as smoke sensor) receives the smoke signal first and alarms the central control system at the same time.

消防中央控制系统通过识别后接通火警所在区域的防火卷帘门电源，使火灾区域的防火卷帘按一定的速度下行。当卷帘下行到离地面约1.8米位置时，停止下行，以利于人员的疏散和撤离。防火卷帘门在中间停留一定时间后，再继续下行，直至关闭。防火卷帘门的下行速度和中间停留时间可在安装时进行调整。

After identification, the central fire control system connects the power supply of the fire shutter door in the fire area to make the fire shutter in the fire area descend at a certain speed. When the roller shutter descends to a position about 1.8m above the ground, stop descending to facilitate the evacuation and evacuation of personnel. After the fire shutter door stays in the middle for a certain time, it continues to go down until it is closed. The downward speed and intermediate residence time of the fire shutter door can be adjusted during installation.

在某些场合，建筑内不配备消防中央控制系统，防火卷帘门仅借助于防火卷帘门的消防控制电器箱实现防火卷帘门的防火规定运行程序。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至防火卷帘门的消防控制电器箱。

On some occasions, the building is not equipped with a central fire control system, and the fire-proof rolling shutter door only realizes the fire-proof specified operation procedure of the fire-proof rolling shutter door with the help of the fire-proof control electrical box of the fire-proof 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 fire shutter door.

在停电的情况下，只能通过拉动铁链将防火卷帘门放下。防火卷帘门配备的手动，只能单向放下，不能提升。

In case of power failure, the fire shutter door can only be lowered by pulling the iron chain. The manual fire shutter door can only be lowered in one direction and cannot be lifted.

防火卷帘门的制作要求较高，即要求整个系统能经受一定时间的1100°左右高温考验，防火卷帘门的耐火时间是防火卷帘门的主要指标。

The manufacturing requirements of the fire-proof rolling shutter door are high, that is, the whole system is required to withstand the high temperature test of about 1100 ° for a certain time. The fire resistance time of the fire-proof rolling shutter door is the main index of the fire-proof rolling shutter door.
