The appearance of smoke detector is different from that of temperature-sensitive fire detector. The lower part of the smoke detector is circular, and the inner lining is wrapped with a wire mesh; The lower part of the temperature detector is umbrella-shaped, and there is a water drop glass ball in the umbrella-shaped.
2. Different uses
Smoke detectors only need to detect smoke, dust, water vapor, etc. The temperature detector is mainly used for detection and alarm of 67 degrees -9 1 degree.
3, the principle is different
There is a black maze inside the smoke detector, and the smoke from the super maze can give an alarm. Temperature detectors generally use thermistors as sensors. In order to detect the fire as soon as possible, the thermistor should be exposed, which is easy to damage the sensor in traffic engineering and is generally protected by plastic.

Installation location:
Temperature-sensitive fire detector: adopts high-performance two-bus address coding and analog transmission mode, which has the characteristics of small monitoring current, high reliability and analog output. Products are suitable for restaurants, hotels, commercial buildings, office buildings, bookstores, archives, computer rooms, cinemas and other public places. And other halls and public places where smoke detectors are not suitable. Not suitable for places that may produce black smoke, dust flying, steam and oil mist.
