Fire alarm and extinguisher system DET-AC III Master

Article number: DK 7338.121

Compact fire alarm and active extinguisher system with smoke extraction system with 1RU space. For security safes and sealed server racks applications.

Article number:
DK 7338.121
Product description
The 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.
