Sounds like a perfect use for an Arduino driven speaker. There are thousands of publicly posted circuits that will probably net a simple solution, or the name of a local person who would love to help/ adapt one for this purpose.

At present, only a red indicator light goes on when the grid is down. It would need to run off 120 VAC. Does anyone have any suggestions?
