Alarms
The RFM-LR1 LoRa module have several alarm functions built in.
When an alarm is detected the corresponding alarm flag in the status data is set. When any alarm flag is set
the status, data is included in every report. The alarm flag must be reset manually using a Downlink command.
Module removed
If the module is removed from the water meter after activation this alarm flag is set.
Magnetic fraud attempt
The module has a detector that can sense if a magnet is used to manipulate the function of a dry dial water
meter. If a magnet is sensed the alarm flag is set.
Flow exceeds Q3
If the flow exceeds Q3 for more than 10 minutes the alarm flag is set. Q3 depends on the water meter (based
on pipe) and should be configured using a Downlink command. The default Q3 value is based on the largest Q3
for the specific series.
Leak detection
If a continuous flow has been detected for 24 hours the alarm flag is set. Two configurations parameters are
used for this alarm, Leak window size and Leak zero tolerance, and these can be configured using Downlink
commands. The leak window size defines how long it should be between the detected water meter movements
to consider no flow.
Alarm reset
The alarm flags are reset by setting the Status data with a Downlink command. Setting it to 0 resets all alarms.
Setting it to 0xFE resets alarm flag 0.
