    Characteristics

    • This detector operates on the temperature differential sensing principle, with a UL approved sensor making mechanical contact. It is made of high quality material, providing excellent contact despite any environmental interference.
    • This detector is suitable for locations with high temperatures differentials, such as places (kitchen, restaurant and boiler house) where there is constant use of heat.
    • This detector has passed strict quality control and repetitive testing; hence its quality is durable and highly reliable.
    • Through its professional design, the heat collector can accelerate its response rate after being heated, and has a protective device to avoid accidental response caused by distortion, bumping and dropping in order to increase the reliable product.
    • The unit is completely sealed; its function is not affected by humidity, dust or insects.
