Hey Joe, thanks for the warm welcome. Firstly, let me say that your solution is absolutely brilliant. I never would have thought of it. I'm going to put the idea to the customer for consideration, but he's probably not going to go for it. I'm not sure what he'll like less...having the doorbells chiming twice, or having a second switch on his door with a cable running between the two. He's quite fussy. His fussiness is why I can't use the switch that Ed (EV607797) posted earlier...to much of an eyesore no matter how well it works.
Westuplace...thanks for the tip on the different chime unit. I think it's too late to swap out the actual chime. It's been a few days since I was on-site and the painters may be complete now. The old chimes would have to come down, the screw holes would need to be patched and the exposed area painted. I wish I had found out about this model earlier, I probably would have chosen it.
I fell like I'm shooting down all of your great ideas, it's just that this customer wants things just so. If I can't swap out the chimes then I suppose I'll just have to find the right relay and buy two of them along with boxes to mount them in. Oh well, that's the way it goes sometimes. Next time I'll know better!
Thanks again, you guys are awesome, I hope I can return the assistance some day.
Shawn.
