16. An intake monitoring system (200) for detecting or locating a fire, an outbreak of fire, or a hazardous situation, which intake monitoring system (200) has a fluid line system with at least one pipe or hose line (210), which opens into one or more monitoring regions via one or more intake openings for the respective removal of a fluid sample, and a detection unit (220) for detecting fire or hazard parameters contained in the fluid sample, characterized in that the intake monitoring system (200) generates a fluid flow within the pipe or hose line (210) and includes blocking valves (140), a fluid blower (100) with a fan and is connected to the pipe or hose line (210) via a connector (130), so that, during operation of the fan (120) the fluid flow within the pipe or hose line (210) is generated in a first direction of flow (S1) or in a second direction of flow (S2) as a function of the respective position (PS, PB) of the blocking valves (140).
