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劃分防火分區(qū)，控制分區(qū)建筑面積所設(shè)防火墻和防火隔墻上的門。當(dāng)建筑物設(shè)置防火墻或防火門有困難時(shí)，要用防火卷簾門代替，同時(shí)須用水幕保護(hù)，而且相關(guān)規(guī)定要求要求防火、防煙的隔墻分戶門。

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.

按標(biāo)準(zhǔn)，防火卷簾門還應(yīng)帶有儲(chǔ)備電源，在沒有主電源的情況下，儲(chǔ)備電源也可以派上用場(chǎng)。當(dāng)然，在門內(nèi)還可設(shè)置熔斷裝置，當(dāng)溫度升到一定程度，內(nèi)部金屬片就會(huì)熔斷。這種門在平時(shí)多會(huì)閑置不用，需在每個(gè)季度都開啟一次，檢查相關(guān)電路、部件等是否運(yùn)行正常。若在使用中出現(xiàn)故障，應(yīng)立即切斷電源，排除故障。所以防火卷簾設(shè)置位置一定要按照相關(guān)的要求進(jìn)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.
