style="text-indent:25px">防火門(mén)監(jiān)控系統(tǒng)是用于顯示并控制防火門(mén)打開(kāi)、關(guān)閉狀態(tài)的裝置。一般由防火門(mén)監(jiān)控器、防火門(mén)電動(dòng)閉門(mén)器、防火門(mén)電磁釋放器、防火門(mén)門(mén)磁開(kāi)關(guān)等設(shè)備組成，有些廠家還配有區(qū)域分機(jī)、輸入/輸出接口、普通閉門(mén)器、普通門(mén)磁開(kāi)關(guān)等。鑫豪斯的防火門(mén)監(jiān)控系統(tǒng)分為一體式和分體式。一體式：防火門(mén)控制器主機(jī)、由電動(dòng)閉門(mén)器、門(mén)磁開(kāi)關(guān)。分體式：防火門(mén)監(jiān)控器、由普通閉門(mén)器，普通門(mén)磁開(kāi)關(guān)，電磁門(mén)吸，電磁釋放器，輸入輸出模塊。防火門(mén)等級(jí)劃分：甲級(jí)不小于1.2h，乙級(jí)不小于0.9h，丙級(jí)不小于0.6h。不同等級(jí)防火門(mén)適用：甲級(jí)：設(shè)備房（如消防泵房、配電房、發(fā)電機(jī)房、防排煙風(fēng)機(jī)房等）門(mén)、防火分區(qū)、防火墻上開(kāi)門(mén)；乙級(jí)：封閉樓梯間門(mén)、樓梯間前室門(mén)、防煙樓梯間與消防電梯合用前室門(mén)、消防電梯前室門(mén)、直接開(kāi)向前室或合用前室的戶門(mén)；丙級(jí)：豎向井道門(mén)，如強(qiáng)電井、弱電井、管道井門(mén)、空調(diào)機(jī)房。</p><p style="text-indent:25px">防火門(mén)設(shè)計(jì)中結(jié)構(gòu)設(shè)計(jì)很重要，很多完整性喪失的情況往往是結(jié)構(gòu)造成的，而不是門(mén)芯材料的耐火性能造成的，如果加強(qiáng)對(duì)防火門(mén)結(jié)構(gòu)的重視，往往會(huì)增強(qiáng)防火門(mén)性能，降低防火門(mén)成本。鎖位門(mén)縫竄火和中縫竄火原因類似，但還可能因?yàn)殒i舌長(zhǎng)度太短或數(shù)量太少，導(dǎo)致鎖閉力不夠造成。另外，如果鎖盒材料或結(jié)構(gòu)設(shè)置不合理，也會(huì)導(dǎo)致鎖位面板被燒穿，喪失完整性，可以通過(guò)增加鎖位的填充物密實(shí)度或增設(shè)防火板和密封條來(lái)解決。上縫竄火是普遍的現(xiàn)象，單扇門(mén)一般是鎖測(cè)上縫與側(cè)縫交接位置，雙扇門(mén)一般是上縫和中縫交接位置。原因分析：該位置為薄弱，約束力小，變形比較大。單扇門(mén)合頁(yè)側(cè)一般設(shè)置3~4個(gè)合頁(yè)均勻分布，不會(huì)發(fā)生很大變形，而且上面還有閉門(mén)器約束，而鎖側(cè)只是在中間一個(gè)位置有鎖舌約束，上側(cè)也無(wú)閉門(mén)器約束，所以該位置且離鎖約束遠(yuǎn)，離合頁(yè)和閉門(mén)器約束也遠(yuǎn)，變形比較大。雙扇門(mén)也有同樣的原因，一般是帶鎖扇鎖側(cè)上角容易翹曲變形，導(dǎo)致火焰竄出，喪失完整性。要根據(jù)不同建筑所，安裝的不同防火卷簾門(mén)。</p><div
