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.
