These fire detectors are classified into heat detectors for detecting heat in the event of fire, smoke detectors for detecting smoke, flame detectors for detecting flame, and the like. It detects a lamp and transmits a fire detection signal to an electrically connected receiver to generate a fire alarm sound.

In addition, fire detectors are legally installed in buildings larger than a certain scale, and are used in many home appliances such as gas ovens and gas stoves in kitchens where fires are easily generated inside buildings. Recently, karaoke rooms, PC rooms, It is used for installation in large buildings.

However, when the heat detector or the flame detector is installed outdoors and exposed to the sun, there is a problem in that a malfunction that often generates a fire alarm occurs even though the sensor part is heated by direct sunlight and is in a non-fire state.

In addition, when the smoke detector is installed in the inside and outside of the house and exposed to fog or yellow sand, the dust particles contained in the atmosphere are introduced into the detector together with the air and are detected as the smoke particles, thereby generating a fire alarm despite the non-fire state.
