style="text-indent:25px">西雅格應(yīng)急照明燈的安裝和維護(hù)：1、在火災(zāi)狀態(tài)下，靠近地面的煙少、氧氣多，人疏散的本能反應(yīng)是彎腰或匍匐前進(jìn)，因而局部高照度照明比高位。安裝帶來的均勻照度更為有效。所以應(yīng)提倡低位安裝，即在靠近地面或在地面高度上提供疏散應(yīng)急照明。2、應(yīng)急燈均以放電狀態(tài)出廠，使用前必須進(jìn)行20小時的充電，才可進(jìn)行放電。3、使用中的應(yīng)急燈具應(yīng)定期進(jìn)行性能檢查，每半個月或一個月通過連續(xù)開關(guān)試驗，以檢查電路轉(zhuǎn)換及電池的應(yīng)急功能，并進(jìn)行放電，以延長電池使用壽命。深圳哪里有西雅格應(yīng)急照明供應(yīng)西雅格應(yīng)急照明燈不管正常照明電源有否故障，能持續(xù)提供照明。</p><div
