溫感探測器 利用著火時產生的溫度探測火災的傳感器稱為感溫探測器。分為差溫、定溫和差定溫三種。
差溫探測器是在發生火災時溫升速率達到一定值而報警;定溫探測器是利用低熔點合金達到一定溫度后而報警;差定溫探測器則是前兩種的組合。感溫探測器宜適用于感煙探測器不能應用的濕度大、有粉塵、和蒸氣及正常情況下有少量煙霧的場所,如發電機房、汽車庫、吸煙室、廚房、鍋爐房等建筑物內。感溫探測器不適用于陰燃火災的場所。

一. 性能:
報警聲音: ≥80dB(或無聲)
供電電源: DC9V~DC28V
電 流: 靜態電流 ≤200uA
報警電流 ≤45mA
工作溫度: -10℃~+50℃
相對濕度: ≤95%RH(40℃±2℃)
輸出形式: 聲光報警/繼電器無源觸點(NO/NC可設置)輸出。
二. 功能:
自檢:按下檢測按鈕,探測器LED常亮,同時發出報警音響(注:自檢僅對于探測器本身內部功能進行檢測,自檢時無繼電器信號輸出
工作:正常情況下,探測器大約每隔6秒指示燈會閃亮一下。探測器自動檢測周圍環境中的溫度,并根據使用環境狀況進行靈敏度自動補償。當溫度接近報警值,探測器加快對溫度濃度趨勢進行智能運算,同時報警指示燈開始閃亮。若運算結果達到或超過報警值,探測器開始聲光報警,并啟動繼電器輸出。當周圍環境的溫度降低到報警值以下時,探測器自動恢復正常工作狀態。
輸出:無源觸點輸出;觸點容量24V/1A,可通過探測器內部的跳線,設置為常開或常閉觸點輸出。出廠時跳線默認設置觸點為常閉。

1. GENERAL DESCRIPTION
The detectors are photo-electronic detector uses a state of-the-artoptical sensing chamber. This detector is designed to provide open area protection and to be used with most security alarm control panel.
Two LEDs on each detector provide local 360° visible alarm indication. They flash every six seconds indicating that power is applied and the detector is working properly. The LEDs latch on in alarm. LEDs will be off when a trouble condition exists indicating that the detector sensitivity is outside the listed limit. The alarm can be reset only by a momentary power interruption.
The detector that initiated the alarm condition will have its red LED and relays latched until reset by panel.
Heat detector and smoke & heat detector combine a photo electronic sensing chamber and a temperature heat detector.
