In addition to the functions of ordinary doors, fire doors also have special functions such as fire prevention, smoke isolation, suppression of fire spread, and protection of personnel evacuation. They are widely used in densely populated areas such as high-rise buildings and large shopping malls.

防火卷簾門(mén)主要用于大型（大型），大型，大型材料市場(chǎng)，大型展廳，工廠，倉(cāng)庫(kù)等具有防火要求的公共場(chǎng)所。當(dāng)發(fā)生火災(zāi)時(shí)，防火卷簾門(mén)在火控系統(tǒng)的控制下根據(jù)預(yù)設(shè)程序自動(dòng)降低（向下），從而防止火焰蔓延到其他區(qū)域并獲得實(shí)施滅火的寶貴時(shí)間。
