摘要： A fire distinguishing device comprises: a detection means for detecting an outbreak of fire; a fire presence/absence distinguishing means for distinguishing the presence/absence of the fire; and a cumulative time determining means for determining the cumulative time required for the fire presence/absence distinguishing means to distinguish the presence/absence thereof. The cumulative time determining means distinguishes the environment type of environment in which the detection means is placed or the phenomenon type of phenomenon detected by the detection means and further determines the cumulative time depending on the distinguished environment type or phenomenon type.

摘要： Disclosed is a detector having a smoke density detection vs. time characteristic and a gas concentration detection vs. time characteristic which are displaced from each other, thereby having the advantages of both early detection of a fire and prevention of a false report of a fire. Specifically disclosed is a detector (10) provided with: a labyrinth (32) for shielding against external light to prevent the light from directly entering the detector; and a smoke detection unit for receiving on a light reception unit (30) light diffused by the smoke flowing into a chamber (26) which is provided with an insect net (34) covering the periphery of the labyrinth (32), wherein the light reception unit (30) is disposed in the chamber (26) so as not to directly receive the light emitted from a light emitting unit (28). A cover (12) of the detector (10) receives a thermal air current and has an opening (20) in the surface thereof. An electrochemical gas sensor (36), which brings gas generated by a fire into contact with an electrolyte solution through the opening (20) and thereby detects the gas by use of electrodes, is disposed within the cover (12) behind the opening (20).

摘要： Abstract To advantageously ensure both early detection of a fire and prevention of a false alarm by giving a time lag between temporal detection properties of smoke density and gas concentration. A detector 10 includes a smoke detecting section that includes a light-receiving unit 30 at a position at which the light-receiving unit 30 does not directly receive light emitted by a light-emitting unit 28 in a chamber 26 in which a labyrinth 32 for preventing light from directly entering from the outside and an insect net 34 covering the rim of the labyrinth 32 are provided, the light-receiving unit 30 receiving light scattered by smoke flowing into the chamber 26. An opening hole 20 is formed open in the surface of the cover 12 receiving hot air current, of the detector 10. In the cover 12 behind the opening hole 20, an electrochemical gas sensor 36 is placed to bring gas generated by a fire through the opening hole 20 into contact with an electrolyte solution to detect the gas by an electrode.

摘要： A detector 1 is equipped with a smoke sensor 15, a CO sensor 16, an acquisition unit 275, and a determination unit 276. The smoke sensor 15 detects the concentration of smoke within a monitored area, and the CO sensor 16 detects the concentration of CO gas within the monitored area. The acquisition unit 275 acquires a CO-smoke conversion coefficient for the detection value of the smoke sensor 15 and/or the detection value of the CO sensor 16 on the basis of the detection value of the smoke sensor 15 or the detection value of the CO sensor 16. The determination unit 276 determines whether an abnormality has occurred within the monitored area on the basis of the detection value of the smoke sensor 15, the detection value of the CO sensor 16, the CO-smoke conversion coefficient acquired by the acquisition unit 276, and a determination threshold value.
