Detector types and application

There are several either standard or optional system detectors. The Detectors menu
shows all installed detectors. The accessibility / inaccessibility of detectors (black /
gray label) depends on actual system conditions.

Note
For settings and handling of particular standard / optional detectors, see Chapters 5 and 7.
