3.10.1 Radio gateway FDCW221 diagnosis levels
The radio gateway monitors its operation largely autonomously.
The following diagnosis levels are derived from the different control measurements:
● Normal
● Replacement recommended
● Replacement necessary
● Fault
For details, see table below.
When a fatal error occurs, which impairs the function of the radio gateway, a fault
message is reported and displayed on the control panel.
To remedy the cause, additional information is available in the radio gateway. This
can be displayed by the detector exchanger and tester FDUD292 or the intelligent
detector tester FDUD293 (as of software V2.1) for example.
You will find more information in documents 007227 and 009718.
