8 Multi-sector installation
Multi-sector extinguishing systems are capable of protecting several flooding
zones. The basic setup consists of one common cylinder bank. To this cylinder
bank, a piping network is connected to every flooding zone by means of selector
valves. By opening the relevant selector valve, the extinguishing agent is guided to
the desired flooding area.
Up to 16 extinguishing panels (XC1003-A exclusively) can be inter-connected via
there individual modules (XCA1030) to a common module (XCA1031). This
application and its operation are defined at programming step 58 (see paragraph
12.16).
8.1 Functional description
Each extinguishing control panel controls everything from one flooding zone.
Panels are networked so that information’s can be exchanged from one panel to
the other.
As soon as an extinguishing control panel is activated (either automatically or
manually), the common pilot cylinder is released. Then, the corresponding sector
valve is opened and the number of cylinders that correspond to the flooding zone is
released.
After having released the extinguishing in one flooding zone, the automatic release
of other flooding zones can be automatically blocked in order to keep the
concentration in the first flooding zone or to prevent unwanted fire detection in the
others.
All connected devices are monitored like the single-sector application. In addition,
the common cylinder loss of agent information is reported to all linked panels.
