Description

Compact fire alarm and active extinguisher system with smoke extraction system, built into one height unit for use in security safes and closed server racks.

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 the smoke extraction system in the EFD III. The extinguishing process begins automatically when a main alarm is activated. For the extinguishing process, the tank is pressurised via a propellant cartridge. The extinguisher gas Novec™ 1230 evaporates at the extinguisher nozzle and is distributed in the server enclosure.
