In the CS1140 fire detection system, the logical structure is completely separated from
the physical structure. This enables the greatest possible flexibility. Display and control
terminal are based on the geographical and organizational aspects and are independent
of the actual hardware installation of the detector network.

Logical structure
The logical structure is a con-
figuration of the geographical
features of a system. It can
be modified easily to the
building structure, room uti-
lization etc.
Within the same control unit
the logical structure is inde-
pendent of the wiring of the
detector network.
Linking
The lowest levels of both
structures are linked to each
other. It is determined which
physical devices (e.g. detec-
tors) are in which logical or
geographical location.
Physical structure
The physical structure is a
configuration of the hardware.
It results from the hardware
installation. The number of
used levels is depending on
the type of hardware.
