Find a local house basher to programme it up for you is another option but he might still charge you £250?
Perhaps get all your equipment on the wall in each position and then work on a circuit at a time
But as swb said this is way over your head , wrong choice of panel really should have bought Yale as a fun project
Correct , with resistors in place
Is it a door contact with no tamper ?
Good bloke you can then also get an RF card later I believe and have wireless zones , unless you already have that
Don't that's worst mistake
Work out which sensors you need on now
Think about where you want expander which may just be next to control panel and order one
You will just open more fault finding problems trying to get eol working on sensors paired up when you don't need to
As before op you still have config issue and your missing it or mixed something up
Save the config current and default the panel and only setup the remotes
