<DIV class=t_msgfont id=postmessage_12914209>切断应急灯的主电源来启动自身蓄电池，行吗？<BR>答：不行。<BR>因为应急灯的主电源同属消防电源，消防时绝对不应该被切除，从而去实现自身蓄电池的自动投入（针对那些消防时可能处于熄灭状态的蓄电池灯具而言）。这种做法叫做“挖东墙，补西墙”，或叫“隔靴搔痒、南辕北辙”。<BR><BR>蓄电池只是备用电源，只有在万不得已时（如主电源因自身故障退出运行）才被迫投入的；并非一发生消防，就要投入蓄电池（备用电源）。<BR><BR>应急灯若无法自动投入，一般只有采用常明方式，从而满足消防最低照度要求。</DIV></DIV>

<DIV class=t_msgfont id=postmessage_12916435>那种带电池的双头灯，真正的用途是停电应急灯，并非是消防时用的，之所以人们都认为那是消防应急灯，那是长期的一个误解，尤其是公安部消防局制定标准的人，他们根本就没有搞清楚应急灯是如何强制点亮的，他们应该立即修改应急灯的国标，明确这种两线制的停电应急灯，如果没有强制点亮端子，就不能认为是消防应急灯，而只是停电应急灯。正是因为消防局制定标准的人本身都是稀里糊涂的人，长期把这种停电应急灯当作消防应急灯，才会造成目前的混乱局面。请访问<a href="http://www.szqdt.com/" target="_blank" >www.szqdt.com</A>，了解目前新型智能照明开关，带有强制点亮功能，由应急电源（第二高压电源、发电机、EPS）+双电源应急照明箱+带强制点亮端的开关+（不带电池的）应急照明灯具，才是应急照明最合乎要求的设计方法！</DIV></DIV>

<P>[em106]你是切断主电源用短暂的备用电源，肯定不合理，我只见消防队的这样用。</P>
