I have had numerous issues going from the original system(that worked on great) to the "upgraded " system. The only reason I went to the new one is because my co detector went out and they don't make it any more and gave me a new system for free.(Get what you pay for I guess) I went thru two weeks of countless hours on the phone with techs trying to help with small victories but continuing glitches. Then by some miracle everything started working for a couple of days, or so I thought. Came home today and it had been on HOME all day(pets) When I entered thru the front door there was no alarm beeping. I waited for a couple of minutes with nothing happening. Went to the back door and opened it and same thing. Called a tech and they couldn't figure it out. I opened a third entry sensor on a window and the alarm finally activated. Reset the system to HOME and two keypads now showed Out Of RANGE, even though they are only twenty feet or so from the base station with just a couple of interior walls between. The base station is situated in a back bedroom where I can barely hear it because it is the only place on the main floor that doesn't have a WIRELESS INTERFERENCE DETECTED warning blaring out. I even unplugged all of my other devices and removed the remotes from the house to test when I installed and still get that warning. I have basically been without an alarm system for 3 weeks now and I am frustrated to no end. I am to to the point that I am about to take out the New and Improved system and replace my old system. Not sure what to do here. Based on the reviews I am reading it sounds like this new system is a piece of junk that doesn't work well in a lot of places.
