FIRE WARNING APPARATUS

摘要

PURPOSE: A fire warning apparatus is provided to increase reliability of fire discrimination by detecting ultraviolet and infrared ray of a specific wavelength generated from flame. CONSTITUTION: A housing(10) is installed inside a building. A sensor part(20) detects ultraviolet ray, infrared ray, and haze due to firing in the housing. An alarming part generates an alarm according to a detecting signal form the sensor part. The sensor part includes an infrared detecting sensor(21), an ultraviolet detecting sensor(22), and a haze detecting sensor(23). The sensor part additionally includes a human body sensor(24) and a carbon dioxide detecting sensor(25). The alarming part includes a control part, an alarm speaker(32), and a light(33).
