防火卷帘设置位置的选定要求是什么？

According to the requirements of architectural design process, in addition to the firewall, the fireproof roller shutter shall also be set between the two fire zones if there is no firewall. The fire shutter is generally set in the closed evacuation stairs leading to the walkway; Close the elevator room, the inspection door of the door cable shaft leading to the front room and the walkway, the garage door pipe shaft, smoke exhaust duct, garbage duct and other vertical pipe shafts.

按照要求建筑物中一般划分防火分区，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，而且相关规定要求要求防火、防烟的隔墙分户门。

According to the requirements, the building is generally divided into fire zones, and the fire wall and the door on the fire partition are set to control the building area of the zone. When it is difficult to set fire wall or fire door in the building, it shall be replaced by fire rolling shutter door, which shall be protected by water curtain, and relevant regulations require fire-proof and smoke-proof partition door.

按标准，防火卷帘门还应带有储备电源，在没有主电源的情况下，储备电源也可以派上用场。当然，在门内还可设置熔断装置，当温度升到一定程度，内部金属片就会熔断。这种门在平时多会闲置不用，需在每个季度都开启一次，检查相关电路、部件等是否运行正常。若在使用中出现故障，应立即切断电源，排除故障。所以防火卷帘设置位置一定要按照相关的要求进行。

According to national standards, the fireproof rolling shutter door shall also be equipped with reserve power supply. In the absence of main power supply, the reserve power supply can also be used. Of course, a fuse device can also be set in the door. When the temperature rises to a certain extent, the internal metal sheet will fuse. This kind of door is usually idle. It needs to be opened once a quarter to check whether the relevant circuits and components operate normally. In case of any fault in use, the power supply shall be cut off immediately to eliminate the fault. Therefore, the setting position of fire shutter must be in accordance with relevant requirements.
