Looking for ideas. I have an alarm system in a government building basement. A computer room with 2 large AC units, a walk in UPS, Wires top and bottom all over a raised floor ect. It is a Moose Z2000 4 key pads tow door strikes 16 zones two batteries ect. It's been there ten years I have changed the main board three times in the ten years. I like it but it gets a fit every so often. Monday I was called the keypad keeps beeping for a long time. I found some entry time was changed to an odd number and a zone changes I know now one go in to the prograhaming I looked at the printer log and memory.
Why and How. Cellphone next to the keypad? Generator starting?
