Diagnosis levels
The device largely monitors its function by itself. The following diagnosis levels are
taken from the different control measuring processes:
Normal
Fault
For details, see table below.
When a fatal error occurs, which impairs the proper function of the alarm sounder,
a fault message is signaled.
To correct the cause of the fault, additional information is available in the device.
The additional information can be displayed using e.g. the detector exchanger and
tester FDUD292 or the intelligent detector tester FDUD293.
You will find more information in documents 007227 and 009718.
