Hi when the alarm is unset door closed all zones are clear no lights on if I open the door it remains the same no lights showing until I enter my code then zone 1 lights up and the alarm continues to beep and not set if I omit zone 1 and enter my code the alarm sets as normal. I replaced the door contact thinking it maybe that it made no difference still the same can you please help me I am retired and just want to make my home a bit more secure. Thanks
