Abstract: A water extinguishing system has an extinguishing fluid supply adapted to provide an extinguishing fluid, at least one pump adapted to convey the extinguishing fluid from the extinguishing fluid supply into a supply line to a pipe system of the water extinguishing system, and a control unit adapted to operate the at least one pump in a controllable manner. The control unit is configured to start and to operate the pump for a pump test run on provision of a start signal and to end the pump test run and to stop the pump on provision of a stop signal. The control unit has a signal suppression unit which is adapted to at least temporarily suppress the provision of the stop signal in the event of a fire. The signal suppression unit is configured to be free of executing a computer program. A corresponding method operates a water extinguishing system.

Abstract: The present invention comprises a device (1100) for monitoring a storage height (2100) of a warehouse (2000), in particular a shelf warehouse, preferably a high-bay warehouse, comprising at least: a sensor (1110) that is in particular designed to be arranged in an upper region of the warehouse (2000), wherein the sensor (1110) is configured so as: to perform a distance measurement (Di, DN) of a distance (Di, DN) that is substantially horizontal with respect to the warehouse (2000) and that monitors a predefined maximum storage height (2120), and a measurement and/or control unit (1120) that is configured so as to output a message (F, W) in the event of an exceedance (Ü) of the predefined maximum storage height (2120) being detected by the sensor (1110).

Abstract: The invention relates to a water extinguishing system (1) with a fluid supply (20), a pump (30) and a test line (40) with an opening element (2) which is configured to open the test line (40) during a test run of the pump (30). According to the invention, the test line (40) further comprises a closing element (4) which is configured to close the test line (40) if the water extinguishing system (1) is triggered.
