5.3 Alarm Reporting
Simplified Alarm Reporting
It is preferred to reduce the number of alarms in such a way that, for each unique alarm, there is a specific action to be
taken by the operator. Within each reported alarm, there can be additional descriptive text strings that can be used to
debug the specific fault condition. The list of LoRa gateway alarms is shown in Table 5-2.
