[0002] Intelligent fire detectors are devices used in the automatic fire alarm system to investigate the scene and detect fires. Fire detectors are the "sensory organs" of the system. Their function is to monitor whether there is a fire in the environment. Intelligent fire detectors are equipped with smoke sensors and single-chip microcomputers, and have powerful analysis and judgment capabilities.
