All that text and I left something out.  Some UPSen provide a relay which
will close when the UPS is getting near the end of its power supply.
You have to wire a connector that will interface to a port on your equipment
and have some process monitoring that port and recognise when the relay
switches.  i.e. it can be done but it usually isn't pretty.

At the Office in addition to the raft of Knapcos we have we have our
uVAX on an American Power Conversion 1200 VX (which we also got from
KNAPCO) that has such a relay.  We haven't gone through the hassle
of trying to figure out how to get it to do anything for us yet, however.
