Abstract:
1. Method for detecting and localizing a fire and/or the origin of a fire in one or more monitored areas comprising the following process steps: a) extracting air samples in each case representative of the room air of the respective individual monitored areas from said individual monitored areas through a common suction pipe system; b) detecting at least one fire parameter in the air samples suctioned through suction pipe system with at least one sensor for detecting fire parameters; c) blowing out the extracted air samples within suction pipe system by means of a blower or suctioning/blower device; d) re-extracting air samples from the individual monitored areas through suction pipe system at least until the at least one sensor re-detects a fire parameter in air samples; e) evaluating the time elapsed before the re-detecting of the fire parameter in the re-extracted air samples from process step d) in order to localize a fire or the site of an imminent fire in one of the plurality of monitored areas; and f) emitting a signal indicating the development and/or presence of a fire in one or more of monitored areas, wherein the signal contains further information for a precise localization of the fire in said one or more monitored areas.
