FIRE DETECTION DEVICE, AUTOMATIC FIRE EXTINGUISHING DEVICE, AND AUTOMATIC FIRE EXTINGUISHING SYSTEM

摘要

This fire detection device is provided with: a fire monitoring unit 10 that detects the carbon monoxide concentration, smoke density, and temperature of a warning area α; a threshold setting unit 31 in which a threshold is set; a fire determination unit 41 that determines the outbreak of a fire by comparing the threshold with the carbon monoxide concentration, smoke density, and temperature; a transmission unit 33 that transmits a fire signal; a human detection sensor 21 that detects a room occupant in the warning area α; a thermosensor 22 that detects the body temperature of the room occupant; and a room occupant determination unit 42 that determines the presence/absence of a room occupant and determines the condition of the room occupant. The room occupant determination unit 42 determines the condition of the room occupant when the fire determination unit 41 determines that a fire has broken out, and the transmission unit 33 transmits a fire signal and transmits a determination result for the condition of the room occupant, thereby enabling early detection of the outbreak of a fire and making it possible to clearly and quickly confirm whether there is a person who has failed to escape at the time of the outbreak of the fire.
