火(huo)災自動報警系統是(shi)設置在(zai)建筑物或其他場(chang)所中(zhong)的一種自動消(xiao)防設施，能早期發現和通報火(huo)災。

火(huo)災(zai)自動報警(jing)(jing)系統(tong)通常由觸發裝(zhuang)置如(ru)火(huo)災(zai)探測器(qi)、報警(jing)(jing)裝(zhuang)置如(ru)火(huo)災(zai)報警(jing)(jing)控(kong)(kong)(kong)制器(qi)、警(jing)(jing)報裝(zhuang)置如(ru)聲(sheng)光報警(jing)(jing)器(qi)、聯(lian)動控(kong)(kong)(kong)制裝(zhuang)置如(ru)總線(xian)控(kong)(kong)(kong)制盤與控(kong)(kong)(kong)制模塊、電源等組成。

工作原理(li)(li)(li)：在火災(zai)初(chu)期，將燃(ran)燒(shao)產生(sheng)的煙(yan)霧、熱量和光輻射等物理(li)(li)(li)量，通過感煙(yan)、感溫(wen)和感光等火災(zai)探測器(qi)(qi)變成電信號(hao)，傳輸到(dao)火災(zai)報警控(kong)制器(qi)(qi)，信號(hao)經火災(zai)報警控(kong)制器(qi)(qi)處理(li)(li)(li)、分析、判斷后，以聲、光、文字等方式顯(xian)(xian)示出(chu)來(lai)并同時(shi)顯(xian)(xian)示出(chu)火災(zai)發(fa)(fa)生(sheng)的部位，記錄火災(zai)發(fa)(fa)生(sheng)的時(shi)間(jian)。

聯動(dong)控(kong)制(zhi)：火(huo)(huo)(huo)(huo)災自動(dong)報警系(xi)(xi)統(tong)(tong)(tong)一般和預(yu)作(zuo)用系(xi)(xi)統(tong)(tong)(tong)、雨淋系(xi)(xi)統(tong)(tong)(tong)、水幕(mu)系(xi)(xi)統(tong)(tong)(tong)、水噴(pen)霧系(xi)(xi)統(tong)(tong)(tong)、水炮系(xi)(xi)統(tong)(tong)(tong)、氣體滅火(huo)(huo)(huo)(huo)系(xi)(xi)統(tong)(tong)(tong)、防(fang)(fang)排煙(yan)系(xi)(xi)統(tong)(tong)(tong)、通風(feng)系(xi)(xi)統(tong)(tong)(tong)、空調系(xi)(xi)統(tong)(tong)(tong)、常開防(fang)(fang)火(huo)(huo)(huo)(huo)門、防(fang)(fang)火(huo)(huo)(huo)(huo)卷簾、擋(dang)煙(yan)垂壁、消(xiao)防(fang)(fang)廣(guang)播等設備聯動(dong)。在火(huo)(huo)(huo)(huo)災情況下，控(kong)制(zhi)器如在自動(dong)狀態，會自動(dong)啟動(dong)防(fang)(fang)排煙(yan)風(feng)機、停止(zhi)新風(feng)機、關閉防(fang)(fang)火(huo)(huo)(huo)(huo)閥、釋放防(fang)(fang)火(huo)(huo)(huo)(huo)門、防(fang)(fang)火(huo)(huo)(huo)(huo)卷簾以(yi)及擋(dang)煙(yan)垂壁等，也能(neng)自動(dong)啟動(dong)預(yu)作(zuo)用、雨淋、水幕(mu)、水噴(pen)霧和水炮泵，還(huan)能(neng)在消(xiao)防(fang)(fang)控(kong)制(zhi)室直接啟動(dong)消(xiao)防(fang)(fang)泵和防(fang)(fang)排煙(yan)風(feng)機。
