Abstract
The invention relates to an inert gas fire-extinguishing system for reducing the risk of and extinguishing fires in a protected room. So as to have the inerting of the protected room ensue according to different variable sequences of events, the inert gas fire-extinguishing system includes a pressure-reducing device having at least two parallel branches, wherein each parallel branch has a pressure-reducing mechanism. Each parallel branch is connectable to a high-pressure collecting line and a low-pressure extinguishing line via a controllable valve, whereby each pressure-reducing mechanism is designed to reduce a high input pressure to a low output pressure according to a known pressure-reducing characteristic curve.
