電氣火災監控系統


電氣火災監控系統是指當被保護線路中的被探測參數超過報警設定值時,能發出報警信號、控制信號并能指示報警部位的系統。

當電氣設備中的電流、溫度等參數發生異常時,終端探頭(如剩余電流互感器、溫度傳感器等)利用電磁場感應原理、溫度變化等對該信息進行采集并輸送到監控探測器里,經放大、轉換、分析、判斷,比對,同時也輸送到監控設備中,再經監控設備進一步識別、判定,當確認可能會發生火災時,監控主機發出火災報警信號,點亮報警指示燈,發出報警音響,同時在液晶顯示屏上顯示火災報警等信息。值班人員則根據以上顯示的信息,迅速到事故現場進行檢查處理,并將報警信息發送到集中控制臺。

與傳統火災自動報警系統不同的是,電氣火災監控系統早期報警是為了避免損失,而傳統火災自動報警系統是為了減少損失。可廣泛用于工廠、學校、醫院、商場、賓館、劇院、寫字樓及工程項目等場所。

      JB-QB-OZH6900是能接收來自電氣火災監控探測器的報警信號,當被保護線路中的被探測參數超過報警設定值時,能發出聲、光報警信號和控制信號,指示報警部位,記錄并保存報警信息的裝置。它由電氣火災監控設備、電氣火災監控探測器組成。通過探測被保護線路中的剩余電流(漏電流)變化及當前溫度狀態,將探測信息傳于電氣火災監控設備。

      ◆ 采用無極性二總線,可配接250只監控探測器。

      ◆ 共2-4路總線,每路總線帶192地址,單機最大容量為384-768。

      ◆ 采用大屏幕漢字液晶顯示。

      ◆ 用戶操作分級,不同級別給與不同的系統操作權限,便于管理。

      ◆ 具有歷史信息存儲查詢功能,存儲記錄:≥10000條。

      ◆  配備專用微型針式打印和熱敏打印機,漢字打印機,可隨時打印報警、啟動、反饋、故障等信息。
