Because of several requests, I am posting the following:

The system I mentioned is called Showdown and is distributed by:

	Continental Information Systems Corporation
	PO Box 248
	Itasca, IL 60143-0248
	(312) 250-8111

It is available for a variety of platforms, I don't recall the complete list
right off and can't find the product brochure.  It consists of a transducer
that plugs into the wall and a serial port on the computer and has software
to monitor that port.  When a power failure is sensed, it begins your system's
normal shutdown procedure with user definable delays for warnings and the
start of the final shutdown sequence.  These should be tailored to your UPS
to ensure things get closed down before the power really dies.

Hope this helps,
