海灣GST-MD-M9514火災光警報器

服務熱線：4000346119

一、GST-MD-M9514概述

　　GST-MD-M9514火災光警報器（以下簡稱警報器），用于顯示室內火災探測器報警情況。一般安裝在巡視觀察方便的地方，如會議室、餐廳、房間等門口上方，當房間內探測器報警時，警報器上的指示燈根據警報器設置的設備類型可以自動閃亮，也可以通過控制器聯(lián)動啟動閃亮，使工作人員在不進入室內的情況下就可知道室內的探測器已觸發(fā)報警。

二、GST-MD-M9514特點

　　1.與控制器進行通信采用數字信號，工作穩(wěn)定可靠，對電磁干擾有良好的抑制能力；

　　2.地址碼為電子編碼，可由電子編碼器事先寫入，也可由控制器直接改寫，工程調試簡便。

三、GST-MD-M9514技術特性

　　1.工作電壓：總線24V允許范圍：16V～28V

　　2.工作電流：

　　監(jiān)視電流≤0.6mA

　　動作電流≤5mA

　　3.閃光頻率：每分鐘閃亮125±15次

　　4.編碼方式：電子編碼方式，編碼范圍可在1～242之間任意設定

　　5.線制：信號二總線無極性

　　6.使用環(huán)境：

　　溫度：-10℃～+50℃

　　相對濕度≤95%，不凝露

　　7.外形尺寸：86mm×86mm×43mm（帶底殼）

　　8.殼體材料和顏色：ABS象牙白

　　9.重量：約127g

　　10.安裝孔距：60mm

　　11.執(zhí)行標準：GA385-2002

四、GST-MD-M9514結構特征與工作原理

　　1.警報器外形示意圖如圖1所示。

GST-MD-M9514火災光警報器

　　2.工作原理

　　由控制器總線傳輸的經調制的24V脈沖信號，輸入信號經整流二極管組成的橋轉化為無極性信號，一路去穩(wěn)壓電路，另一路經脈沖整形電路取出調制信號，由單片機進行處理。單片機內含EEPROM，用于存儲地址碼、設備類型等信息。單片機主要完成收發(fā)碼、光信號定時控制、內部檢測等功能。
