Single container systems with a pneumatic release device have a pilot cylinder that is activated
electrically. The control gas flows through a pilot line from the pilot cylinder to the pneumatic
release device for the extinguishing agent container and opens it.
Use single container systems without a pilot cylinder only if you have ensured that the extinguishing
agent that flows out does not pose a danger to people.
4.1.2 Multi container systems
FIGURE 4-2: Multi container system
Multi container systems feature several extinguishing agent containers interconnected via a pilot
line. They are required, for example, if a large protection zone must be protected.
In multi container systems without a pneumatic release device, the first extinguishing agent con-
tainer (master) is actuated electrically in the same way as in single container systems (and option-
ally also manually). All other extinguishing agent containers (slaves) are opened pneumatically
through a pilot line.
Multi container systems with a pneumatic release device feature a pilot cylinder that is triggered
electrically. The control gas flows through a pilot line from the pilot cylinder to the pneumatic
release devices for the extinguishing agent containers and opens them.
In contrast to single container systems, the extinguishing agent initially flows from the hose
through check valves into a manifold if a multi container system is actuated. From there, the extin-
