Charles--- While testing, I had the whole system on one breaker. I did this to make sure they were on the same buss bar or circuit. I would be interested in knowing if I had THREE bad components or a bad console. Either way The heart of the system didn't work for me. The bad thing about security systems is that every one I checked on is MADE IN CHINA. To be honest, I have never seen a quality product that came from this communist country. Just the times we live in ! Thanks for your interest.
