The fire detector is an equipment that explores the scene in the automatic fire alarm system and discovers the fire of the fire.The fire detector is the "sensation organ" of the system, and its role is to monitor whether there is a fire in the environment.Once there is a fire, the characteristics of the characteristics of the fire, such as temperature, smoke, gas, and radiation light, etc., and immediately move the alarm signal to the fire alarm controller.
The role of fire detector
The fire detector can play a good role in preventing fires. When the fire occurs, such a device will issue a alarm signal in the first time.Let the fire be effectively controlled at the beginning.

Fire detector classification
Considering the convenience of measurement and practicality, the fire detectors we often use are mainly five categories: smoke, temperature sensing, light sensitivity, combustible gas body, and composite type.(1) Smoke -sensitive fire detector.In the first two stages of the fire, a large amount of gas solution and smoke will be generated.One of the most important features of the early fire of fires is that many smokes are produced. Smoke -sensitive fire detectors are a response instrument through the detection of visible or invisible smoke particles concentration.Converted to the corresponding telecommunications signal to achieve the alarm.Smoke -sensitive fire detectors can be divided into ion -sensible smoke detectors and optical smoke detectors.Among them, ion -sensitive smoke detectors use the impact of smoke on 镅 241 with radioactive properties, so as to detect the reaction by detecting circuits and respond.(2) Temperature -sensitive fire detector.During the fire burning process, a lot of heat will be generated, which will increase the temperature around the surrounding temperature.The detector that responds to the temperature parameter that can be transformed by changing temperature changes to the electrical signal is a temperature -sensitive fire detector.According to the different measurement basis, the temperature -sensitive fire detector can be divided into three types: fixed temperature, different temperature, and different temperature type.
