Diagnosis levels
The FDSB291 sounder base monitors its operation largely autonomously.
The following diagnosis levels are derived from the different control measurements:
Normal
Observe information
Fault
For details, see table below.
When a fatal error occurs, which impairs the proper function of the sounder base, a
fault message is signaled. To remedy the cause, additional information is available
in the sounder base. This can be displayed by the detector exchanger and tester
FDUD292 or the intelligent detector tester FDUD293, for example.
For details, see Documents 007227 and 009718.

Sounder base present, but parameters not
set
Set permissible parameters
Fault present
Invalid parameter settings (e.g. no sounder
base present)
