I just finished installing mine today, I have the orange double gang jboxs with open backs that I mounted for each uno-s2 originally but had to change things abit to make it work, we cut the right side of the jbox out and cut out small piece of drywall..the compoint is now attached by decora screws to the face plate..I then have the four russound screws holding the faceplate snug to the Uno-S2.
**You can use decora screws for holding the S2 but you will have to tap the holes slightly larger(compoint accepts decora screws)..you can attempt to screw in the decora screws but they are tight and I had one snap off in another Uno..I plan to change to the decora screws asap..just got this installed tonight
The second one I have installed is a Abus keypad and a Compoint in a dual gang in my kitchen..this installation it was a mud ring? Forgive a first time homeowner but they are just the silver squares with holes for screws and no backs and I think they are called mud rings
..this was in the tile on my kitchen counter and I bought longer screws to reach it...also behind this one there is a vapor seal because its an exterior wall.
I agree the units are large..trying to wire it up to the Abus beside it with speaker wires from that to compoint was not easy and then having to crouch down because of the height..lotsa fun
Thanks to Paul from sbsmarthomes.com from getting me the system and for the wallplates for the S2 and compoint together..works great!
Used the system a few times tonight and we are very impressed..the mic is very sensitive, our great room is about 15-20 feet from that counter and during a tv show I chatted with the wife from my office downstairs and could hear her excellent...no yelling and no stomping feet to communicate!
Later she went into the spare room about the same distance away and had the door half closed and I accidentally paged the kitchen and she heard the *ping* and I heard her say "Your a geek"..I replied and was able to hear her no problem.
