消(xiao)防(fang)(fang)應(ying)(ying)急燈普遍(bian)安裝在(zai)公共場合的過道和(he)消(xiao)防(fang)(fang)通(tong)道門，它是消(xiao)防(fang)(fang)安全(quan)專業設備。在(zai)市(shi)場上的很多消(xiao)防(fang)(fang)應(ying)(ying)急燈具由消(xiao)防(fang)(fang)安全(quan)單位(wei)的消(xiao)防(fang)(fang)安全(quan)單位(wei)生產制(zhi)造(zao)，具備多種多樣作用(yong)(yong)，但作用(yong)(yong)大部(bu)分降低了。當(dang)消(xiao)防(fang)(fang)應(ying)(ying)急燈斷(duan)電時(shi)(shi)，當(dang)有(you)來電時(shi)(shi)，消(xiao)防(fang)(fang)應(ying)(ying)急燈會自動點(dian)亮和(he)熄滅(mie)。消(xiao)防(fang)(fang)應(ying)(ying)急燈用(yong)(yong)作備用(yong)(yong)照(zhao)明(ming)設備。該(gai)電池配有(you)一個(ge)電池，在(zai)斷(duan)電時(shi)(shi)提供電能，在(zai)通(tong)電時(shi)(shi)給(gei)電池充電。接下來就給(gei)大家講講這個(ge)消(xiao)防(fang)(fang)應(ying)(ying)急燈蓄電池的一些相關知識：

　　1.蓄電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)不成(cheng)功因為充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)池常(chang)(chang)常(chang)(chang)處在淺正電(dian)(dian)(dian)(dian)荷和淺電(dian)(dian)(dian)(dian)情況，電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)量不夠(gou)或失效，務必(bi)換電(dian)(dian)(dian)(dian)池。 當(dang)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路Q2對(dui)蓄電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)時，電(dian)(dian)(dian)(dian)流量挺大而(er)且非常(chang)(chang)容易毀壞。

　　2 .如果沒有(you)交(jiao)流電源(yuan)，主電源(yuan)指示燈d14不亮，常見的故障是變壓器(qi)長時間連(lian)接。

　　消防(fang)應急燈對位(wei)置(zhi)安裝(zhuang)要求有：

　　1.消防應急(ji)燈(deng)和安全疏散指示器必須有兩(liang)個電(dian)(dian)(dian)(dian)(dian)(dian)源：正常電(dian)(dian)(dian)(dian)(dian)(dian)源和緊(jin)急(ji)備(bei)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)源。緊(jin)急(ji)備(bei)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)源通常作為自供電(dian)(dian)(dian)(dian)(dian)(dian)和電(dian)(dian)(dian)(dian)(dian)(dian)池供電(dian)(dian)(dian)(dian)(dian)(dian)，使用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)池時連續上電(dian)(dian)(dian)(dian)(dian)(dian)時間不能少于(yu)200分鐘。

　　2.應急照明(ming)和(he)安全燈指(zhi)示燈應至少為(wei)0.5 lx，以完全照亮人行道，樓梯(ti)和(he)其他疏散通(tong)道。消(xiao)防控制室(shi)，消(xiao)防泵房，獨立發(fa)電廠房和(he)仍需要保(bao)存在火(huo)中的部件應配(pei)備普通(tong)照明(ming)。

　　3.安全(quan)疏散標志應位于太(tai)平門頂部或逃(tao)生通道壁的角落及其下方1m處，標志之間的距離不(bu)得(de)超過20m。消(xiao)防應急燈(deng)和(he)安全(quan)疏散燈(deng)必須配備由(you)玻璃和(he)其他不(bu)燃材料制成(cheng)的保護罩。

　　4.消(xiao)(xiao)防(fang)(fang)逃生應(ying)(ying)急(ji)燈必須位(wei)于墻壁或(huo)天花板(ban)上(消(xiao)(xiao)防(fang)(fang)雙頭應(ying)(ying)急(ji)燈，消(xiao)(xiao)防(fang)(fang)應(ying)(ying)急(ji)天花板(ban)燈，消(xiao)(xiao)防(fang)(fang)應(ying)(ying)急(ji)燈/聚(ju)光燈等(deng))。消(xiao)(xiao)防(fang)(fang)應(ying)(ying)急(ji)照(zhao)明位(wei)于消(xiao)(xiao)防(fang)(fang)通道或(huo)安全出(chu)口兩側，距離樓梯頂部(bu)或(huo)樓梯頂部(bu)2.2米。長(chang)途疏散路線應(ying)(ying)該跟著火災(zai)。根據(ju)部(bu)門(men)的(de)指示或(huo)實際使用場所的(de)應(ying)(ying)急(ji)照(zhao)明強(qiang)度(du)，提(ti)高燈密度(du)并(bing)合理安裝。

　　5.緊急逃生指(zhi)示器或安(an)(an)全(quan)出(chu)口(kou)指(zhi)示器的安(an)(an)裝(zhuang)距離不得超(chao)過20米，消防安(an)(an)全(quan)出(chu)口(kou)指(zhi)示器的安(an)(an)裝(zhuang)規格，安(an)(an)裝(zhuang)高(gao)度和燈(deng)密度應符(fu)合實(shi)際(ji)(ji)安(an)(an)裝(zhuang)環境(jing)和應急燈(deng)的實(shi)際(ji)(ji)安(an)(an)裝(zhuang)和使用(yong)。
