I just needed a quick doorbell, mine broke, but I couldn't find one..... I'm sure the models could be tweeked a bit, but I was in a hurry. and it did the job, the button was suposta say Wrong House and have a gun inside, maybe if I get more time this need week i'll clean it up when I took my old doorbell apart it had two spring like metal pieces in it, I just screwed them into the wires coming out of my house and then on to the base, then take the button and the cover and wiggle it on... its a tight fix but it worked well for my quick fix.
