火災自動報(bao)警系統(tong)是設置在建筑物或其他場所中的(de)一種自動消防設施，能(neng)早(zao)期發現(xian)和通報(bao)火災。

火災自動報警(jing)系統(tong)通常由觸發裝(zhuang)置(zhi)如(ru)火災探測器(qi)(qi)、報警(jing)裝(zhuang)置(zhi)如(ru)火災報警(jing)控(kong)(kong)制(zhi)器(qi)(qi)、警(jing)報裝(zhuang)置(zhi)如(ru)聲光報警(jing)器(qi)(qi)、聯動控(kong)(kong)制(zhi)裝(zhuang)置(zhi)如(ru)總線(xian)控(kong)(kong)制(zhi)盤與(yu)控(kong)(kong)制(zhi)模塊、電(dian)源等組成。

工作原理：在火災(zai)初期，將燃(ran)燒產生的(de)煙霧、熱量(liang)和(he)光(guang)輻射等(deng)物理量(liang)，通過(guo)感(gan)(gan)煙、感(gan)(gan)溫和(he)感(gan)(gan)光(guang)等(deng)火災(zai)探測(ce)器變成電信號(hao)，傳(chuan)輸到火災(zai)報(bao)警(jing)控制器，信號(hao)經火災(zai)報(bao)警(jing)控制器處理、分析、判斷后，以聲、光(guang)、文字等(deng)方式顯示出來(lai)并同時顯示出火災(zai)發(fa)生的(de)部位，記錄火災(zai)發(fa)生的(de)時間(jian)。

聯(lian)動(dong)(dong)(dong)控(kong)制(zhi)：火(huo)(huo)災自動(dong)(dong)(dong)報警系(xi)(xi)統(tong)(tong)一般和預作用系(xi)(xi)統(tong)(tong)、雨淋(lin)系(xi)(xi)統(tong)(tong)、水(shui)(shui)幕系(xi)(xi)統(tong)(tong)、水(shui)(shui)噴霧(wu)系(xi)(xi)統(tong)(tong)、水(shui)(shui)炮(pao)系(xi)(xi)統(tong)(tong)、氣體滅火(huo)(huo)系(xi)(xi)統(tong)(tong)、防(fang)排(pai)(pai)煙(yan)系(xi)(xi)統(tong)(tong)、通風系(xi)(xi)統(tong)(tong)、空(kong)調系(xi)(xi)統(tong)(tong)、常開防(fang)火(huo)(huo)門、防(fang)火(huo)(huo)卷簾、擋(dang)煙(yan)垂壁(bi)、消(xiao)(xiao)防(fang)廣播等(deng)設備聯(lian)動(dong)(dong)(dong)。在(zai)火(huo)(huo)災情況(kuang)下，控(kong)制(zhi)器如(ru)在(zai)自動(dong)(dong)(dong)狀態，會自動(dong)(dong)(dong)啟(qi)(qi)動(dong)(dong)(dong)防(fang)排(pai)(pai)煙(yan)風機(ji)(ji)(ji)、停止新風機(ji)(ji)(ji)、關閉防(fang)火(huo)(huo)閥、釋(shi)放防(fang)火(huo)(huo)門、防(fang)火(huo)(huo)卷簾以及擋(dang)煙(yan)垂壁(bi)等(deng)，也能自動(dong)(dong)(dong)啟(qi)(qi)動(dong)(dong)(dong)預作用、雨淋(lin)、水(shui)(shui)幕、水(shui)(shui)噴霧(wu)和水(shui)(shui)炮(pao)泵(beng)(beng)，還能在(zai)消(xiao)(xiao)防(fang)控(kong)制(zhi)室(shi)直(zhi)接啟(qi)(qi)動(dong)(dong)(dong)消(xiao)(xiao)防(fang)泵(beng)(beng)和防(fang)排(pai)(pai)煙(yan)風機(ji)(ji)(ji)。
