基本性能Features：
l 2U面板式安裝結(jié)構(gòu)（1U=44.45mm），簡潔大方。Compact design, the panel merely occupies 2U rack room.
l 大型帶背光液晶顯示屏，實(shí)時時鐘顯示，觸摸按鍵、數(shù)字鍵盤、人性化操作。Large backlit LCD screen, digital keyboard, and is user-friendly operation.
l 采用2n線制的多線接線方式，每門分機(jī)電話線長度適于1500米以內(nèi)。2N wiring installation, the maximum wiring distance is 1500 meters.
l 1～40門分機(jī)地址，可配接消防電話分機(jī)和消防電話插孔。Refer to different configuration, system may have 1 ～40 loop zones
l 通話自動錄音，可自動記錄通話地址和時間，在分機(jī)已被注冊的情況下，總機(jī)具有電話線路短路斷路故障判斷能力，并有聲光故障報警。Automatically record calls and calling information. All loops are real time monitored for open or short circuit.
l 消防電話分機(jī)摘機(jī)或插孔式消防電話分機(jī)插入消防電話插孔中可直接呼叫消防電話總機(jī)?？倷C(jī)可通過地址操作與多部分機(jī)呼叫和通話。消防電話分機(jī)、消防電話插孔都設(shè)有工作狀態(tài)指示燈。Calls to telephone exchange will be made when extensions off-hook or plug handset into jacks; throught digital keybroad, exchange is supported to call fews of extensions.
l 電話插孔HD230可多個并聯(lián)使用，線路末端電話插孔接入7.5kΩ/0.25W金屬膜電阻，可用于電話線路開路故障判斷。The 7.5KΩ/0.25W metal film resistor accessed in each loop zone is to detection the open or short circuit.
l 每路最多可并聯(lián)掛接電話插孔（HD230）60個或電話分機(jī)（HD210）4部。 System allows to connect 4 telephone extensions or 60 telephone jacks for each loop zone.
