SELF-CONTAINED INSTALLATION FOR SPACE EXTINGUISHING OF FIRE Russian patent published in 1999 - IPC

FIELD: fire-extinguishing equipment, in particular, stationary self-contained systems for detection of fire and extinguishing of fire by means of generated aerosol. SUBSTANCE: installation has power-containing means for fire detection connected via starting pulse device with units for initiating of aerosol-generating pyrotechnical charges in generators. Aerosol-generating charges are secured inside generator body having holes for discharge of fire-extinguishing aerosol mixture to space under protection. Novelty consists in that power-containing means for fire detection are made in the form of converters of spring potential energy, chemical energy of burning of powder charge and kinetic energy of magnetically hard core of magnetizing coil into electric signal of starting of system and connected electrically with units of initiating of aerosol generator by means of heat chemical source of current. EFFECT: higher response, simplified design of installation, improved operating reliability and reduced cost of installation. 2 cl, 3 dwg
