The invention relates to a suction particle detection system (100) for detecting a fire, comprising a fluid line system (200) which opens into one or more monitored areas (i), and having a suction device (230), connected in a fluid-guiding manner to the at least one pipe and/or hose line (210) in order to generate a test fluid flow (240) along the at least one pipe and/or hose line (210), and a light guiding system (300) having one or more local detector modules (320) and designed for the local capture and transmission of scattered light scattered at scattering and/or smoke particles and/or designed for the capture and transmission of transmitted light passing through the scattering and/or smoke particles. In the suction particle detection system (100) at least one light guide (310) is connected to the one or more local detector modules (320) and a central analysis device (110) for evaluation.
