Logical and physical structure

5 Logical and physical structure
Main building (area)
Logical structure
The logical structure is a map of a system's
geographical circumstances. It can be flexibly
adapted to the building structure, room use,
etc.
The logical structure within a control panel is
independent of the line arrangement of the
detector network.
Link
The lowest levels of the two structures are
linked to one another. The physical units (e.g.
detectors) at each logical or geographical
location are determined.
Physical structure
The physical structure is a map of the hard-
ware. It is provided by the hardware installa-
tion. The number of levels used depends on
the hardware used.

The logical structure in the CS1140 fire detection system is totally separate from
the physical structure. This allows for maximum flexibility. Display and operation
are oriented towards geographical and organizational aspects and are not depend-
ent on the detector network's effective hardware installation.
