After over a year and a half since I posted this, several more contacts have stuck (on windows that are never opened).

I would say common on those standard contacts

Anyway I'm adding a few PIR's to act as backup (and implementing an exercise schedule for the windows ).

Everything should be tested once a month on the user walk test anyway?

User test every 10years or never

Why do you need 22 contacts anyway? You only need to put them on external entries/exits, let the PIR's do their job.

Depends on how many opener's he has

 

Pirs won't do perimeter protection but save money tho

Insurers like every external door contacted

Funny that many entries are the kitchen windows , or the panel in the door

Contacts have limited use for detecting a break in, they are mandatory for making sure the numpties shut all the doors.

As 6wb to lower risk to prevent doors being left open as well as detection
