Claim 10:
11. A method for detecting or localizing a fire or a fire emergence in one or more monitored areas (i) using a suction particle detection system (100), the method comprising
in a first step (A), removing a respective amount of test fluid from the one or more monitored areas (i) via a fluid line system (200) having at least one pipe or hose line (210) and one or more suction openings (220) each opening into a monitored area (i),
in a second step (B), flowing the amount of test fluid removed from the one or more monitored areas (i) as part of a test fluid flow (211) through one or more local detector modules (320), each assigned to one or more suction openings (220),
in a third step (C), scattered light that is scattered at particles or smoke particles contained in the test fluid flow (211) or in the respective monitored area (i), or transmitted light passing through the particles or smoke particles is captured by the one or more local flow-through detector modules (320),
in a fourth step (D), transmitting the respectively captured scattered light or transmitted light to a central analysis device (110) via at least one light guide (310), and
in a fifth step (E), evaluating the transmitted scattered light or transmitted light by means of the central analysis device (110) to detect a fire or a fire emergence or is assigned to the respective local detector module(s) (320) to localize a fire or a fire emergence.
