I installed a DS7000 kit in early July after my house being vandalised. It works okey until last Saturday Sep-2 that I found no chimes when I opened the door. Then I tried to reprogram (I always did that when the system got any hi-cup like flashing light on one of the devices etc.) it by unplug all the batteries in DSC7000 as well as the window/door sensors and the heat motion sendors, key chain RC and palm RC etc. Now it won't connect to any of my devices any more. AC power light still on, if I pressed the alarm button on DSC7000 itself it still starts dinging, but the remote just don't turn it off. It's not totally dead, yet, but just don't communicate with other devices. I even opended up some new sensors in my stock and tried to hook it up but just don't talk with each other. Can anyone help what's wrong with my system and how to fix it? Should I return to X10 and get a new one?
