The alarm system is already set up. It involves and Idec ice cube relay with a 240 V coil connected between L-1 AND L-2 of the AC in bus bars. When the grid drops out, the relay reverts to the N/C position, allowing a 120 V contact to send power to a box in the dining room (that has the indicator light on it).
I've done this before, and it works well. The only issue with this one is that the client wants to have an audible alarm as well as the light. Doorbell buzzers (according to tech support) will burn out if left on, and would make a lot of racket. Chimes are one shot ding dongs. We may try to find an old fashion radio that you can plug in (and leave on) and have it go on as soon as its attachment cord is energized. A CHEAP device that would create some sound is all we are looking for.
