If your builder uses iwired, get a new builder, these guys are the worst of the worst and the low of the low, we built a new house in Mesa Az with William Ryan Homes in the community of Eastmark and had to use them as our low voltage installers, we bought a pre-wire alarm system and the forgot to run all of the contacts at every window and door. So we come to see how the build is doing after dry wall and there is holes at every window and every door, we ask what happend our builder says the forgot the contacts but are reinstalling them, well i guess they couldnt find the wires to our main living room windows or the wire for the motion sensor so they just never installed anything and tried to act like nothing was missing, they also never told us anything after our move in date, thank goodness my wife saw they were not there. Next thier so called customer service or lack of, "Dino" thier new representative was ZERO help after about 5 times on the phone amd would not transfer me to a manager, Please save yourself the headache and do not use this company they truly are horrible.
