3.3.6 Diagnosis levels
The manual call point monitors its operation largely autonomously.
The following diagnosis levels are derived from the different control measurements:
Normal
Replacement necessary
Fault
For details, see table below.
When an error occurs which impairs the correct functionality of the device, a fault
message is reported to the control panel.
To remedy the cause, additional information is available in the manual call point.
This can be displayed by the detector exchanger and tester FDUD292 or the
intelligent detector tester FDUD293, for example.
You will find more information in documents 007227 and 009718.
