Alarm interpretation
The following table summarizes the various interpretations when combining LED
states and audible alarms. Use this table to help understand a pattern of lights and
beeps. Each light/beep is taken in turn and shows linked items, so some of the
data is duplicated in several places to make ease of search better.
Note: There will be no beep if the enclosure is muted.
