<p>The invention relates to an inert gas fire-extinguishing system (100) for reducing the risk of and extinguishing fires in a protected room (10, 10 -1, 10 -2). So as to have the inerting of the protected room (10, 10 -1, 10 -2) ensue according to different variable sequences of events, the inert gas fire-extinguishing system (100) comprises a pressure-reducing device (6) having at least two parallel branches (21, 31, 41), wherein each parallel branch (21, 31, 41) has a pressure-reducing mechanism (22, 32, 42). Each parallel branch (21, 31, 41) is connectable to a high-pressure collecting line (3) and a low-pressure extinguishing line (4, 4 -1, 4-2) via a controllable valve (23, 33, 43), whereby each pressure-reducing mechanism (22, 32, 42) is designed to reduce a high input pressure to a low output pressure according to a known pressure-reducing characteristic curve.</p> |
