None of the lines are working, not even line 1. If I connect my keypads to the other panel (new) it works perfectly. So I now know the issue is with the panel and it affects all the AB lines. Is there a way I can get this fixed or what could be the problem?

I have connected to all the lines and changed keypad addressing as well and still same result, still no comms.

Sorry for getting back to you late. By being new I mean I am not familiar with the Honeywell panels. I stand to be corrected in this, upon powering up a new panel it scans the modules on the bus line an picks them up for enrolment. Mine when I connect the keypad alone it keeps beeping and flashing stars, it does not get to a point where it shows the panel information. I suppose this means there is no communication with the panel. How do I fix this now, both keypad and panel are new from the box, returning this for replacement will take me months +. I connected the 2 with twisted pair mylar.

Hi there, new on the portal. Bought new GD520 kit, firstly wired only the keypad to get it started, bridged all the zones on the board. But when powering up it only buzzes and flashes stars non-stop. Where did I go wrong. All the equipment is new from Honeywell.
