Abstract

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.

Description

technical field

[0001] The present invention relates to a method for identifying and locating fires and / or outbreaks of fire in one or more monitored rooms, and a device for carrying out the method.

[0002] The starting point is a fire detection device with a detector for detecting characteristic values ​​of a fire, to which a representative volumetric fraction of the air in a room or appliance is sent via a suction pipe system using a suction device, such as a suction fan detector.

[0003] The so-called fire characteristic value here refers to the physical value, which can be measured around the place where the fire occurs, such as ambient temperature, solids, or liquids, or gas components in the surrounding air (generating smoke particles or smoke particles, either form vapor or combustion gases), or ambient radiation. Background technique

[0004] The various methods and fire detection devices are known for the detection of fires in advance in the first generation sta...
