Heat detectorsuse two main types of technology: thermocouple and electro-pneumatic. Both detect changes in temperature in the area surrounding the alarms.Like smoke detectors, heat detectors include battery-operated and hard-wired varieties or combine both technologies. One type relies on a mechanical ...
煙感部分受光室感應到因煙粒子而折射的光線,且煙濃度達到設定警報之濃度時,立即回報火警受信總機。 熱感部分在探測器周圍溫度達到火災前期標準時(動作溫度) , 感應子之雙面金屬會翻轉使接點導通(雙面金屬是以兩種不同膨脹系數之金屬銜接,受熱時膨脹造成翻轉) 回報火警受信總機。 構造與特點 *電子線路之零件主要採...
