FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to an automatic water fire extinguishing installation for a multilevel rack warehouse mezzanine, which includes distribution pipelines made with possibility of arrangement in corridors at each level of mezzanine between racks, with sprinkler irrigators arranged in pairs on them, equipped with protective screens and deployed from each other towards racks with fire load with formation between axis of sprinkler irrigator and vertical axis of rack, to which sprinkler irrigator is deployed, angle α of 27 to 48 degrees, providing coverage of the spray pattern of sprayed jets of the height of the rack. Irrigators are equipped with protective screens.
EFFECT: increased intensity of fire source irrigation, increased efficiency of extinguishing.
