The 500r uses a hardwired bell. Any of the 12v intruder sab's will be fine. But look for lower power consumption due to the small psu etc,
ie honeywell ag6
WHat the signal strength to the bell. Could be a range issue. Might be worth temp fitting it by the panel to see how it performs. If all is ok you will need to relocate the bell.
COuld be battery but as they are monitored if expect a battery fault rather than it going missing.
the pm gsm module laows full integration for signalling etc
the cqr dialler is more of a standalone etc unit that will need outputs from the panel to trigger it.
im sure you can build your own, but its not semething i have done.
I do recall the excel having udl options in the past not sure if that still relevant.
The premier is defienetly fully supported via wintex.
Yes
The 9940 has become the 9943

Yes pretty much any pro hard wired detector will work
a cheap one, id recommend the honeywell AG6 / 8
you will have to use a 2.1-2.3 A/h battery in that panel as that is all it will accept.
I would advise you back up your glassbreak sensor with some trap protection. Maybe a dualtec movement detector?
But yes what you have is a workable config
id recommend a honeywell G2-20 / 44 with expansion.
Pirs id recommend optex and honeywell as a brand. But actual sensors depend on the environment.
If you want it to call someone then you either need a voice dialler or some sort of prefessional communicator.
agreed, the m12 is cracking sensor designed for interfacing into other equipment. It is not a standalone unit etc. Nor is it designed to be operated as an interlinked system etc.
