*This detector is operating by temperature differential sensing theory, with ULapproval sensor to connect with metal. It`s made by high quality material, excellent contact to enhance its ability to overcome the bad environment. *Through the professional design, the heat collector can accelerate its response rate after being heated, with the protective device to avoid abnormal function caused by distortion, bumping and dropping in order to increase the stability of product. * With accumulataed water discharger to eliminate leakage of watert from the distributing pipe and ceiling, which may leak into the detector and cause false alarm. * This detector is applicable to the location of high temperature or bigger change on temperature differential, such as places ( kitchen, restaurant and boiler house) where there is constant use of heat. * Its local is completely sealed; function would not effected by humidity, dust and insects. * This detector has passed strict quality control and repetitious test; hence its quality is stable and high reliability.
