Abstract: Noise and room air overpressure on discharge of a gas extinguisher system is reduced. During the discharge, an extinguishing fluid is conveyed from a pressurized container via a container valve and line system to an extinguishing nozzle. At the beginning of the discharge the extinguishing fluid is predominantly present in the line system in liquid phase and after discharge it assumes a predominantly gaseous phase.

Due to the reduction of the mass flow, the sound level of the noise arising is advantageously reduced to a value of a maximum of 100 dB and the room air pressure to an overpressure value ranging from 200 to 1000 Pa.
