Lol ok as if saying I am in London is really going to effect anyone
On a side note , your not asking for anything DIY above , so the convo is an overkill
Just get quotes in and get an alarm fitted (but stay away from risco)
Apart from that I don't remember 9448 using resistors anyway but might be me, thought it was a global tamper , old scrap panel needs to go anyway
So where are your pictures?
Your only using one pair for alarm and tamper if your using eol
There must be another reason the resistors are in the panel and not in the detectors , maybe short cut when last panel change took place
