IEC61850 Channel Signal Strength Alarm
The 61850 protocol also allows you to set a unique Signal Strength alarm for each channel. When it changes states,
a notification is sent to the IEC61850 client (Alarm/Restore). It does not affect operation of the LumaSMART and
cannot be configured locally at the LumaSMART touchscreen.
