A fire distinguishing device includes: a detection device which detects an outbreak of a fire; a fire presence/absence distinguishing device which distinguishes the presence or absence of the fire; and a cumulative time determining device which determines the cumulative time required for distinguishing the presence or absence of the fire, in the fire presence/absence distinguishing device. The cumulative time determining device distinguishes an environment type of an environment where the detection device is installed, or a phenomenon type of a phenomenon being detected by the detection device, and further determines the cumulative time according to the distinguished environment type or phenomenon type.

Fire distinguishing device

A detected information display system in a fire detecting system of the present invention which is equipped with detectors arranged in a warning area and a control panel and achieves a specified information display on a physical quantity detected by the detectors, includes a secondary conversion part to convert the physical quantity detected by the detector to the specified level, a conversion level storage part to store the converted level, an extraction part to extract the maximum level from the levels stored in the conversion level storage part, and a display part which is equipped with level display parts, and keeps the level display part corresponding to the converted level and the level display part corresponding to the maximum extracted level in a visually different condition from each other. The maximum detected physical quantity and the set value to indicate the abnormal level can be rapidly grasped, and the displays of a plurality of detectors can be displayed in an integrated and related manner.
