Logical and physical structure

Main building (Area)
Logical structure
The logical structure is a configuration of the
geographical features of a system. It can be
modified easily to the building structure, room
utilization etc.
Within the same control unit the logical struc-
ture is independent of the wiring of the detec-
tor network.
Linking
The lowest levels of both structures are linked
to each other. It is determined which physical
devices (e.g. detectors) are in which logical or
geographical location.
Physical structure
The physical structure is a configuration of the
hardware. It results from the hardware instal-
lation. The number of used levels is depend-
ing on the type of hardware.
Siemens Building Technologies
Fire & Security Products
In the FC700A 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.
