Fire detection and the fire alarm control panel are not included in the scope of supply of the gas fire extinguishing system. Via a defined standard interface, the extinguishing process is triggered. The central equipment and the storage of the extinguishing agent are located in a room immediately adjacent to the extinguishing area. The piping and the arrangement of the extinguishing nozzles within the system technology room are to be coordinated with the arrangement of the installed components. For the flooding case, approved self-actuating pressure relief valves are provided. The system is to be…
