FIELD: anti-fire equipment. SUBSTANCE: finely dispersed water and inert gas are used as extinguishing compound. Pneumatic locking valve is used as unit for spreading extinguishing compound, for mixing and metering components of the compound. The valve is introduced for water supply pipe-line. The valve opens when pressure is generated in the pipe-line which advances inert gas to consumer. Rectifier provided with electromagnetic drive may be used instead of pneumatic locking valve. The rectifier opens when getting electric pulse generated by installation control board simultaneously with generating command for opening distributing valve and inert gas supply locking member. EFFECT: improved efficiency. 3 cl, 1 dwg
