產品銷售、安裝、維修、保養檢測及(ji)消防安全評估
●產品性能與特點
USC500防設備電源監控系統,是依據標準G28184 (消防設備電源監控系統)研制的,針對消(xiao)防(fang)設(she)備的電(dian)源進(jin)行(xing)監控(kong),通過(guo)檢(jian)測消(xiao)防(fang)電(dian)源的電(dian)流、電(dian)壓(ya)(ya)和開關狀(zhuang)態(tai),從而判斷(duan)消(xiao)防(fang)設(she)備電(dian)源是否有斷(duan)路短(duan)路、過(guo)壓(ya)(ya)欠壓(ya)(ya)過(guo)流以及(ji)缺相、過(guo)戴等故障并報(bao)警、記(ji)錄的監控(kong)系統

●安裝與布線
由于系(xi)統(tong)(tong)中(zhong)通(tong)訊方(fang)式(shi)采用(yong)的是(shi)小幅度的數字信號,易受到空間輻射干(gan)擾報(bao)警(jing)系(xi)統(tong)(tong)廣 播系(xi)統(tong)(tong)等信號干(gan)擾,所以現場布線時(shi),系(xi)統(tong)(tong)的穿(chuan)線管道應獨立(li)敷設,不要同其他報(bao)警(jing)系(xi)統(tong)(tong)、廣播系(xi)統(tong)(tong)等線路(lu)同管穿(chuan)線,這樣可(ke)以保證通(tong)訊質量。
消(xiao)防(fang)電源監控器(qi)(qi)與傳感器(qi)(qi)之間的通(tong)(tong)訊(xun)線(xian)應(ying)(ying)采用屏(ping)蔽(bi)雙絞線(xian),通(tong)(tong)訊(xun)線(xian)敷設距(ju)離(li)長為1200m,如果(guo)通(tong)(tong)訊(xun)線(xian)的使(shi)用距(ju)離(li)超過1200m ,應(ying)(ying)增加中繼器(qi)(qi),當系(xi)統應(ying)(ying)用在強(qiang)干擾(rao)場所(suo)時,通(tong)(tong)訊(xun)線(xian)應(ying)(ying)采用屏(ping)蔽(bi)雙絞線(xian),屏(ping)蔽(bi)雙絞線(xian)端(duan)的屏(ping)蔽(bi)層應(ying)(ying)與現場接近的大地連(lian)接。
