防火卷帘门安装哪些部分现在有了一些改观？

1、 Power supply of fireproof rolling shutter door

防火卷帘门的供电电源应该是消防电源；供电和控制导线的截面积、绝缘面积、线路敷设和保管材质等等都要符合规范要求。防火卷帘门的供电装置的过电流保护值也要符合设计要求。

The power supply of the fireproof rolling shutter door shall be the fire power supply; The sectional area, insulation area, line laying and storage materials of power supply and control conductors shall meet the specification requirements. The overcurrent protection value of the power supply device of the fireproof rolling shutter door shall also meet the design requirements.

二、防火卷帘门控制器

2、 Fireproof rolling shutter door controller

防火卷帘门上面安装的防火卷帘门控制器可以控制防火卷帘门上下、停等动作。在两侧还应该设立手动按钮来控制电动防火卷帘门的升降和停。除此之外，防火卷帘门在下降关闭的时候要提升防火卷帘门的功能，确保提升到位之后能偶自动的恢复到关闭的状态。

The fire rolling shutter door controller installed on the fire rolling shutter door can control the up and down, stop and other actions of the fire rolling shutter door. Manual buttons shall also be set on both sides to control the lifting and stopping of the electric fireproof rolling shutter door. In addition, when the fire shutter door is lowered and closed, the function of the fire shutter door shall be improved to ensure that it can automatically return to the closed state after being lifted in place.

三、防火卷帘门报警系统

3、 Fire shutter door alarm system

防火卷帘门应该设立自动报警控制系统，自动关闭控制装置。疏散通道上的防火卷帘门有探测器两步下降到1.5米或者是1.8米之后，设置延时下降到底的功能。手动设置的速放装置，手动速放装置的比例应该小于50牛顿，牵引力低于150牛顿。安装在疏散通道上的防火卷帘门启闭装饰应该在火灾断电之后手工机械提升下降关闭的防火卷帘门。

The fireproof rolling shutter door shall be equipped with automatic alarm control system and automatic closing control device. The fireproof rolling shutter door on the evacuation passage has the function of delaying the descent to the end after the detector drops to 1.5m or 1.8m in two steps. For the quick release device set manually, the proportion of the manual quick release device shall be less than 50N and the traction force shall be less than 150n. The opening and closing decoration of the fire rolling shutter door installed on the evacuation passage shall manually and mechanically lift and lower the closed fire rolling shutter door after the fire and power failure.
