按消防(fang)規范要(yao)求，聯動控(kong)制(zhi)柜控(kong)制(zhi)電(dian)壓(ya)宜為DC24V，這(zhe)不(bu)僅(jin)會(hui)加很多(duo)中(zhong)間繼電(dian)器(大約2/3)，加很多(duo)觸點和(he)接線(xian)，而且(qie)線(xian)路長，電(dian)壓(ya)損失大，加不(bu)可靠(kao)因素，此(ci)舉看似安(an)(an)全，但失去了(le)可靠(kao)性，有些得不(bu)償失。實際上以前很多(duo)控(kong)制(zhi)柜包括現(xian)在很多(duo)工(gong)廠(chang)的控(kong)制(zhi)柜電(dian)源(yuan)都采用AC220V，從(cong)未聽(ting)說操(cao)作(zuo)人員(yuan)出現(xian)安(an)(an)全問題(ti)，至于檢修人員(yuan)，當(dang)然(ran)要(yao)很熟悉(xi)電(dian)路，且(qie)要(yao)停電(dian)操(cao)作(zuo)，因此(ci)，強電(dian)設備沒必要(yao)采用弱電(dian)操(cao)作(zuo)。因此(ci)，建議消防(fang)主管(guan)部門(men)考慮修改此(ci)項規定。德(de)惠風(feng)機(ji)
