Title:
FIRE DETECTION DEVICE
Document Type and Number:
Japanese Patent JP2023108348
Kind Code:
A
Abstract:
To provide a fire detection device capable of improving accuracy in detecting a fire.SOLUTION: A sensor 100 for detecting a fire in a monitoring area includes: a detection space into which a first detection object due to a fire or a second detection object due to a cause other than the fire flows; a detection section for detecting the first detection object or the second detection object inside the detection space; detection elements 700 for detecting at least humidity; and an identification section for identifying which one of the first detection object and the second detection object is detected by the detection section based on a detection result of the detection elements 700. The detection elements 700 detect the humidity of a fluid containing the first detection object or the second detection object. The identification section identifies which one of the first detection object and the second detection object is detected by the detection section based on a humidity increase to be detected by the detection elements 700.SELECTED DRAWING: Figure 1
