Maybe your hkc installer has included the securcom in your monthly maintenance option
I think hkc would overtake texecom in a big way if there app had a free version
But like you said money isnt the issue
Most diallers factory set to negative trigger so connecting to your bell trigger will also work if you don't know how to programme the pgm output (unless it's the same on this panel)

What he's possibly asking is if you u twisted all the pair's and got the legs mixed up, although I understand what you mean to
Is the cat6 shielded? As on bench length would short , others here have mentioned about this
Temporary fix move ribbon cable about a bit or push it in should resolve the keypad issue short term

I would concentrate on the panel before bell box though , link tr or t at. Panel to 0v temporarily while you try and fix keypad issue
Better to scrap it though
