Abstract: A control device for operating a fire extinguisher system includes at least one hose (3) having an extinguisher nozzle (4) arranged at the end of the hose (3) to be operated by an operator for releasing a pressurized extinguishing fluid. A conveying pump (5) conveys the pressurized extinguishing fluid in the hose (3) towards the extinguisher nozzle (4). A first supply line (7) connects the conveying pump (5) to a tank (8) of a fire extinguisher device, such as a fire extinguisher vehicle (1). A second supply line (9) connects the conveying pump (5) to a stationary extinguishing fluid source (2). A multi-port switch valve (10) connects upstream of the conveying pump (5), proximate the first supply line (7) and second supply line (9).

Abstract: A control device operates a fire extinguisher system. The system includes a hose having an extinguisher nozzle arranged at the end of the hose for releasing pressurized extinguishing fluid. A conveying pump pressurized conveying of the extinguishing fluid towards the extinguisher nozzle. A first supply line connects the conveying pump to a tank of a fire extinguisher vehicle. A second supply line connects the conveying pump to stationary extinguishing fluid source. A controller is positioned at a distance from the extinguisher nozzle and functions as an operations center. A control line runs along the hose to the nozzle end of the hose. A radio device connected to the control line converts signals from the control line into radio signals and outputting the signals. An operator carried portable radio device receives radio signals output by the radio device. An operator carried display displays information based on the transmitted radio signals.
