Unfortunately, no, not yet. I'm working with a 5&7 year old to make sure they are comfortable with arming/disarming, and know the importance of using the alarm. We haven't talked yet about what will happen if they accidentally set it off. Our city only gives you 3 free false alarms, and will then start fining you, which is understandable. I'm also making sure that a little keypad glitch I saw about two weeks ago is gone. So far, seems to be the case, thankfully. I'm still leaning more towards the 4530EX, just because it's cheaper, requires less additions to the M1, and should be a little easier to wire up. After all the talk here, I am assuming I will be getting a separate power supply and battery backup, so am currently researching that now.
