Logical and physical structure
5 Logical and physical structure
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.

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.
