用于 HDM3310總(zong)(zong)(zong)線消(xiao)防(fang)電(dian)話(hua)總(zong)(zong)(zong)機(ji)(ji)間(jian)的網絡連(lian)(lian)接，具有 A/B端，可(ke)各連(lian)(lian)接 1臺消(xiao)防(fang)電(dian)話(hua)總(zong)(zong)(zong)機(ji)(ji)的通訊(xun)總(zong)(zong)(zong)線，實現(xian)數
字通信(xin)和語音(yin)信(xin)號的路由傳輸。 ★ 由通訊總線為網絡(luo)路由器進行供電，無需外(wai)接電源，工作電壓范圍為DC24V±4V。 ★ A/B端在各自接入的通(tong)訊總線系統中(zhong)各占 1位編碼地址，有工作燈指示巡檢狀態。 ★ A/B端采用(yong)隔離電(dian)路設計，可減小(xiao)通訊總線噪(zao)聲串擾。 ★ A端(duan)適于連(lian)(lian)接中心控制(zhi)消防電(dian)話總(zong)機(ji)，而 B端(duan)連(lian)(lian)接其他分區的消防電(dian)話總(zong)機(ji)。 ★ 金屬外殼，不易損毀，抗(kang)干擾能力強。
★ Used for networking two or more HDM3310 addressable telehphone exchange, designed side A and B,
which connect bus-line of two exchanges respectively and realize bridging and networking voice and
digital signal. ★ Power supplied by exchange bus-line, no additional power source needed, rated voltage range: DC18-
DC26V ★ Isolated design between Side A and Side B, to minimizing crosstalk noise. ★ Side A is designed to connect to central control exchange, side B connects to other exchange. ★ Metal shell, not easy to broke, has strong shock resistance and anti-jam capability.
