Abstract: A fire extinguishing system for a vehicle or a boat having a fire extinguisher supplying a fire extinguishing substance through a nozzle to discharge the fire extinguishing substance. The fire extinguisher and nozzle may be spatially separated and connected by an elongated pipe. Additional nozzles may be connected with pipes to the fire extinguisher, or additional fire extinguishers and nozzles may be used instead. At least one valve is used to regulate the flow of the fire extinguishing substance through the pipes to the nozzles. The valve is controlled by at least one impact sensor which opens the valve when a collision of the vehicle with another object is detected by the sensor.
