1. A control device for operating a fire extinguisher system of a fire-fighting vehicle, the fire extinguisher system comprising:
a controller adapted to function as an operations center;
at least one hose having an extinguisher nozzle arranged at an end of the hose by which a pressurized extinguishing fluid is released,
a conveying pump for pressurized conveying of the extinguishing fluid in the hose toward the extinguisher nozzle,
a first supply line to the conveying pump from a tank of a fire extinguisher device,
a second supply line to the conveying pump from a stationary extinguishing fluid source,
a multi-port valve connected upstream of the conveying pump, wherein the first supply line and the second supply line are connected to the multi-port valve, and the multi-port valve comprises a motor-driven pressure-controlled valve, wherein the multi-port valve switches at an adjustable pressure threshold,
a second pump positioned in the second supply line between the stationary extinguishing fluid source and the multi-port valve,
wherein in a first position of the multi-port valve, the conveying pump is connected to the tank, wherein the supply of extinguishing fluid from the tank is switched away from the tank and to the stationary extinguishing fluid source, if the pressure threshold is present at the multi-port valve in the second supply line,
wherein pressure present at the multi-port valve in the second supply line can be defined with the second pump, and
control lines connecting the multi-port valve to the controller.
