基本性能Features：
l 2U面板式安裝結(jié)構(gòu)（1U=44.45mm）,，簡(jiǎn)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(shí)時(shí)鐘顯示,，觸摸按鍵、數(shù)字鍵盤(pán),、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(mén)分機(jī)電話線長(zhǎng)度適于1500米以內(nèi),。2N wiring installation, the maximum wiring distance is 1500 meters.
l 1～40門(mén)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(dòng)錄音,，可自動(dòng)記錄通話地址和時(shí)間,，在分機(jī)已被注冊(cè)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(bào)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(guò)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(gè)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(kāi)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.
