I'm questioning my decision to buy this product. I have the DS7000 console and have 1 motion detector and 3 door window sensors attached. The first couple of days, all was going and working well. Today when opening the door, the light on the sensor flashed, however, it did not trip the alarm. Then the other doors started having the same problem. I continue to mess with it to see if I could figure out the problem. The light on the sensor is always flashing, however, it does not always send a signal to the base. Also, when it does trip (door chime) the light stays on after the door is closed. I also noticed I have to hit the arm button a few times on the home remote to arm the alarm. It seems to me the base is not receiving the signal all the time. The base is centrally located and I cant think of anything that would be interfering. I read through many of the posts trying to find a solution with no avail. Ive tried changing batteries and using different sensors. Any help would be greatly appreciated.
