Good suggestion. ...And, as an enhancement to your suggestion, the start and 
stop times of the outage could be recorded to a spare computer or something.

You could modify the receiver and use an SCR or something similar
as a latching alarm trigger.  Leave the current light in place, but add
an additional one that latches, and a reset button to clear the statE.

Then there's no need for a chart recorder to at least tell if an
alarm has occured since the last time you reset it.
