Hello, I have a home that is pre-wired for security, but there is no installed security system. (Every window and door has a 2-wire hanging out of it, and they all terminate in a big bundle in the furnace room.) I want to hear a 'chime' whenever any window or door in the house is opened or closed. I don't want an actual alarm system. i just want the door/window chime. Does anyone know how to do this? I don't care which window or door is opened/closed.. as long as the "chime" occurs when it is opened or closed. Also, there are three "control panel" wiring locations in the house (in master bedroom, beside main floor door, and beside downstairs door) where there is a 6-wire instead of normal 2-wire like the doors and windows. It would be nice if all of these "control panel" locations did the chime sound when any door/window is opened. (This way, we can hear the chime, no matter where we are located in the house.) I hope that makes sense? Does anyone know how to do this? Thanks!
