I am having the same problem with system not arming. I bought this home with this security system and have never used it. I had a room remodeled and the back door sensor wire was cut and I want to bypass this zone. I did the bypass on the keypad but the green light still does not come on and let me arm the system. I used the installers code and bypassed that zone but still will not arm now it shows all zones open. Should I remove the wires of backdoor zone from panel?
Well all you probably needed to do after cutting the wire was to terminate the two wires together to complete the loop as the original door contact did. This would act as a permanent backup without having to modify the alarm programming. Now that you modified the programming and all the zones show open I'm not sure. What exactly did you change in the installer programming?
