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
Most thieves grab and run
Ana alarm internal sounder is probably more important than external in my view
The noise will hurry them up somewhat and usually don't stick around for long , so damage limitation
