AH-9920 Fixed Temperature Heat Detector ( Horing Lih Taiwan )

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.
