HDM3210消防電話總機為面板安裝(zhuang)(zhuang)方式，可直接安裝(zhuang)(zhuang)在標準(zhun)立式機柜或(huo)琴臺(tai)機柜上(shang)。應連(lian)接符合《GB 16806-2006消防聯動控制系(xi)統》國(guo)家(jia)標準的(de)，輸出直流24V/10A消(xiao)防電(dian)(dian)源及備電(dian)(dian)電(dian)(dian)池組。并可接入(ru)無極性的HD312消防(fang)電話(hua)分機及HD322消防電話(hua)插(cha)孔等，連接方式見上圖(tu)。所(suo)有電話(hua)分(fen)(fen)機(ji)與電話(hua)總(zong)(zong)機(ji)的(de)通話(hua)，是(shi)依靠同一線(xian)纜(lan)實現(xian)的(de)。主(zhu)線(xian)纜(lan)可實現(xian)對主(zhu)分(fen)(fen)機(ji)通信、語音信號(hao)傳遞、消防直流電源輸(shu)送等三(san)項(xiang)功能。電話(hua)線(xian)即總(zong)(zong)線(xian)極限長度可達(da)1500米，總線(xian)纜應(ying)選(xuan)擇(ze)截面(mian)積≥RVS2.5mm2的(de)(de)銅芯雙絞線(xian)(xian)，不線(xian)(xian)時(shi)注意不要與其他消防控制設備的(de)(de)通信(xin)總線(xian)(xian)同管穿線(xian)(xian)，盡量遠離干擾源。電話總線(xian)(xian)上首先應接入總線(xian)(xian)制HD312消防電話分機(ji)及HD322消防電(dian)話插孔設備后，才(cai)能在(zai)其上(shang)外(wai)掛接(jie)入(ru)多線制(zhi)HD210消防電(dian)話分機或HD230消防電話(hua)插孔(kong)，外掛的(de)編碼(ma)(ma)地址(zhi)與被掛的(de)總線(xian)制電話(hua)分(fen)機及(ji)電話(hua)插孔(kong)的(de)編碼(ma)(ma)地址(zhi)相(xiang)同(tong)，如上圖在外掛多線(xian)制電話(hua)插孔(kong)HD230接入時(shi)，應將最末端的HD230的空閑接(jie)線端子上并接(jie)上隨機配給的終端電阻51KΩ/0.25W，以保證可檢測線路(lu)開路(lu)故障。Above picture shows the system wiring, HDM3210 addressable fire telephone panel can be mounted on rack, requires 24V/10A power supply. HD312 addressable telephone extension and HD322 addressable telephone jack are nonpolar connected in the system. The bus-line distance can be 1500 meters at maximum when applying ≥RVS2.5mm2 cable. HD210 or HD230 conventional telephone extensions or jacks can be added on HD312 or HD322, sharing the same address within the system. The whole loop is real time monitored for short or open cases by adding 51KΩ/0.25W resistor at the end of the loop.
