Abstract:
1. Extinguishing system comprising a plurality of extinguishing devices and extinguishing functions designed for local firefighting in buildings, at the location of the source of a fire, the extinguishing device comprising: an extinguishing unit having a nozzle device with a plurality of extinguishing nozzles designed for discharging an extinguishing agent at the location of the source of a fire and for decentralized arrangement in the building, a first extinguishing agent container for receiving extinguishing water, a second extinguishing agent container for receiving an extinguishing water additive, the first and second extinguishing agent containers connected to the extinguishing nozzles in a fluid-communicating fashion, at least one pressure-generating device for discharging the extinguishing agent via the extinguishing nozzles, and at least one fire alarm sensor, the pressure-generating device being designed for generating a discharge pressure of the extinguishing agent of at least 10 bar and the extinguishing agent being dischargable as a spray mist, wherein the extinguishing agent is obtainable from a mixture of extinguishing water with at least one extinguishing water additive, wherein a concentrate comprising at least one pre-swollen superabsorbent polymer in an organic phase is provided as the extinguishing water additive, wherein the organic phase is a biodegradable oil preventing the polymer from further water absorption before mixing with the extinguishing water, wherein the extinguishing water and the extinguishing water additive are fed separately from one another and only mixed with one another directly before the discharge of the extinguishing agent through the extinguishing nozzles, wherein at least one extinguishing device is operable in the extinguishing function independently of other, further extinguishing devices, wherein a common control device is provided for the plurality of extinguishing devices, wherein a plurality of adjacent extinguishing devices are operable simultaneously, and wherein the activation of the extinguishing function of a first extinguishing device only leads to the automatic activation of the extinguishing functions of those further extinguishing devices that are arranged directly adjacent to the first extinguishing device, and wherein those further extinguishing devices that are not arranged directly adjacent to the first extinguishing device are not automatically activated by activation of the extinguishing function of the first extinguishing device.
