弱電系統電源
瀏覽：146次
缺陷：某小(xiao)(xiao)區可視對講及門禁系(xi)統(tong)設備就近采用(yong)市電供電，小(xiao)(xiao)區一(yi)旦停電，可視對講系(xi)統(tong)就停止工作(zuo)，單元門鎖自動打開(kai)，給住戶(hu)的安全帶來(lai)隱患。
原因(yin)分析：系統(tong)的供(gong)電(dian)未考慮(lv)停電(dian)因(yin)素(su)。
解決措施：可視對講單元門口機(ji)增加蓄電(dian)(dian)(dian)(dian)池來(lai)解決供(gong)電(dian)(dian)(dian)(dian)問題。弱電(dian)(dian)(dian)(dian)系統(tong)（除(chu)通訊(xun)、有線、網絡公共設備外）其他設備均須(xu)采用獨立的不間(jian)斷電(dian)(dian)(dian)(dian)源(yuan)來(lai)供(gong)電(dian)(dian)(dian)(dian)，系統(tong)的供(gong)電(dian)(dian)(dian)(dian)方案要經過設計和評審
