Abstract (en)

The method involves sucking compartment air at suction points (6), and blowing a detector (4) from a suction pipe end (21) of a suction pipe system (23). A time measurement is started when a fire characteristic is detected by the detector. The detector (4) or a detector (14) is blown from a suction pipe end (22). The time measurement is terminated, when another fire characteristic is determined by one of the detectors. The suction point with both detected characteristics is identified based on a time difference between two detected characteristics and a system specific location-time function. An independent claim is also included for a device for detecting fire.
