Only problem you might get is the resolution may keep trying to switch u til it finds a compatible one but you have switch to make it stick to source output
That's weird man
On hkc , if the system working on app, customer would get a notification "engineer here"
If system is set you can't access, if system unset you still get that notification , even with engineer access always you get internal bells locally and remotely until you press a key
So customer would hear something
Codes can't be viewed though
Reading what the op is saying again, he can use his system , just not on the app
He wants control over the app , which won't happen no matter what he does
So needs new installer
Plenty of installers on the enforcer etc so should be no problem op
No you can use system but not the app , atleast with hkc that is the case
If it's what your saying with pyronix, must be more to it aswell , op blagger perhaps
Basically get another installer , first year is free I think but you have to pay for this service , he will reset codes which is required if engineer access is not available
Job done
Or don't pay anything and leave it how it is
But it's not what he saying , now it seems you don't know how to wire contact?
What's happens if you place resistor across keypad terminals?
What happens if you connect cable remove contact and put resistor across pair going to keypad ?
What's keypad say then , as then you can follow order of fault finding if you can't test cable directly or have a meter
Unless it's something to do with how you have mapped the zones
