The big question is whether this is an early warning of
something going south in the alternator or voltage regulator.

An accurate voltmeter across your battery(s) is a good thing to have
for many reasons but one of the most important is monitoring your
alternator. With the engine runnning at cruising speed you should be
seeing somewhere between 13.8 and 14.2 volts. Anything less than 13.5
you definitely are not getting full output and should get it checked.

The problem you describe could also be a loose or corroded connection
between the alarm panel and alternator.
