The OP didn't specify that the timer be able to control the appliance...
just that it provide an audible signal upon expiration of time. Nor was
he
specific about whether the timer actually needed to be run from the mains.

Sorry if I failed to read his mind properly... {;)

I assumed that if it was a 3 phase 208 VAC system, and had cycle times like
5 minutes minimum to 8 hours maximum, he wouldn't want manual operation.
