根據《消(xiao)(xiao)防(fang)給(gei)水及(ji)消(xiao)(xiao)火栓系統技(ji)術(shu)規范》G974-2014標準規定，壓力啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)、遠程啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)和(he)硬拉(la)線啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)都是通過(guo)繼電(dian)(dian)器來實現自動(dong)(dong)(dong)(dong)啟(qi)(qi)(qi)泵(beng)的(de)，若繼電(dian)(dian)器和(he)弱電(dian)(dian)信號故障不能自動(dong)(dong)(dong)(dong)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)消(xiao)(xiao)防(fang)泵(beng)時(shi)(shi)，應依靠消(xiao)(xiao)防(fang)泵(beng)控制(zhi)柜設置(zhi)的(de)“機械(xie)(xie)應急啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)”直接(jie)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)消(xiao)(xiao)防(fang)泵(beng)。該“機械(xie)(xie)應急啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)”是通過(guo)機械(xie)(xie)連鎖裝(zhuang)(zhuang)(zhuang)置(zhi)直接(jie)傳動(dong)(dong)(dong)(dong)，來實現直接(jie)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)消(xiao)(xiao)防(fang)泵(beng)的(de)裝(zhuang)(zhuang)(zhuang)置(zhi)。該裝(zhuang)(zhuang)(zhuang)置(zhi)可配置(zhi)星三角啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)和(he)降壓啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)兩種方式。“機械(xie)(xie)應急啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)”啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)手(shou)柄平時(shi)(shi)處(chu)于停(ting)止狀態（帶鎖），緊急火警(jing)時(shi)(shi)必須由(you)被(bei)授權的(de)管理人員操作。“機械(xie)(xie)應急啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)裝(zhuang)(zhuang)(zhuang)置(zhi)”輸(shu)(shu)出(chu)和(he)原控制(zhi)柜內輸(shu)(shu)出(chu)端子相連接(jie)，以實現應急直接(jie)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)消(xiao)(xiao)防(fang)泵(beng)。啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)時(shi)(shi)手(shou)動(dong)(dong)(dong)(dong)啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)手(shou)柄按下90°，消(xiao)(xiao)防(fang)泵(beng)依據所(suo)配電(dian)(dian)器采用(yong)星三角啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)、降壓啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)方式啟(qi)(qi)(qi)動(dong)(dong)(dong)(dong)，停(ting)泵(beng)由(you)有管理權限的(de)人手(shou)動(dong)(dong)(dong)(dong)停(ting)泵(beng)（不可自動(dong)(dong)(dong)(dong)停(ting)泵(beng)或火警(jing)時(shi)(shi)手(shou)動(dong)(dong)(dong)(dong)停(ting)泵(beng)）。

當火(huo)災現場的(de)消(xiao)(xiao)防(fang)水泵控制柜的(de)控制回路(lu)發生故障(zhang)(zhang)時，沒有(you)一個有(you)效的(de)措(cuo)施進行(xing)(xing)補救，只能現場進行(xing)(xing)故障(zhang)(zhang)排查維(wei)修(xiu)，很可能會耽誤大(da)量(liang)的(de)時間以及(ji)(ji)造(zao)成嚴重的(de)后果(guo)。在消(xiao)(xiao)防(fang)新(xin)規《消(xiao)(xiao)防(fang)給水及(ji)(ji)消(xiao)(xiao)火(huo)栓系統技(ji)術規范》中，對(dui)機械應急啟動(dong)裝置進行(xing)(xing)了強(qiang)制要求，不管消(xiao)(xiao)防(fang)泵控制柜的(de)控制回路(lu)是否有(you)發生故障(zhang)(zhang)，現場工作人員都能夠(gou)在5分鐘之內通過機械應急啟動(dong)裝置強(qiang)制啟動(dong)消(xiao)(xiao)防(fang)泵，避免(mian)擴大(da)生命、財產的(de)損失。
