FIELD: fire safety.
SUBSTANCE: device for fire extinguishing contains generator for pyrotechnic unit burning, coupled with the means of distribution of the generated gas in the zone of fire. The device also includes means for regulating of the generated pressure to create a specific profile of oxygen concentration in the zone of fire. These controlling means can be executed, for example in the form of a controlled valve, or represent a special form of the pyrotechnic generator performance. The device is made with the possibility of fire extinguishing in aircraft engines, as it does not include halogen-extinguishing agent.
EFFECT: invention allows to control precisely the duration and level of fire protection zones.
