Please help not sure if this is a first or last resort - I had some issues with alarm some weeks ago when we had a power cut - to cut a long story short i reset the alarm 3 days ago and it was triggering zone 6, I overcame this problem by feeding a loop back in on itself. This seemed fine for 2 days. now when I exit the property and set the alarm I have this continous noise on the panel so therefore I have to turn the alarm off. When this noise occurs no zone is being triggered. I have also changed the battery!! thanks in advance for any help???
