DescriptionThe active extinguisher system includes the smoke extraction system and the extinguisher unit. The smoke extraction system is identical to that used in the EFD III. When a main alarm is triggered the extinguishing process starts automatically. For the extinguishing process the tank is pressurized via a propellant cartridge. The extinguisher gas Novec™ 1230 evaporates at the extinguisher nozzle and is distributed in the server enclosure.
