work. The discharge nozzles distribute the extinguishing agent evenly in the extinguishing
zone.
To fight the fire, the extinguishing agent reduces the relative oxygen level in the air through
oxygen displacement.
To divert the resulting overpressure and the oxygen away from the extinguishing zone, a pres-
sure relief flap is mechanically or pneumatically/electrically opened for the flooding period at
minimum.
As well as the automatic electric release, the system can also be activated manually using
manual electric releases. These releases are usually installed at the extinguishing zone access
point.
For more details and information about the variants of the manual release for the system, see
the applicable local regulations.

FIGURE 4-1: Single container system connection line
Single container systems have only one single extinguishing agent container. They are used
solely for small extinguishing zones. Single container systems have an electric release device
that is fitted to the extinguishing agent container valve. Optionally, a mechanical manual
release device for manually activating the system can be fitted on the electric release device.
