| 摘要 |
The invention relates to a method and a device for identifying and localising a source of fire in at least one monitored region (R1,...,Rn), using a suction pipe system (3) connecting the plurality of monitored regions (R1,..., Rn) and communicating with each individual monitored region (R1,...,Rn) by means of at least one suction opening (4) respectively, a suction device (5) for extracting the air samples (6) respectively representing the ambient air of the individual monitored regions (R1,...,Rn) from the individual monitored regions (R1,...,Rn,) by means of the suction pipe system (3) and the suction openings (4), and a sensor (7) for detecting at least one fire parameter in the air samples (6) extracted by means of the suction pipe system (3). According to the invention, a blowing device (8) is provided for blowing out the air samples (6) sucked into the suction pipe system (3) if the sensor (7) detects at least one fire parameter in the extracted air samples (6). The fire is localised by means of the transit time measurement of a re-extracted air sample containing a fire parameter.
