Support for products are for trade installers.
1 Mostly, PCB and Software same. Cab allows larger standby and larger output PSU.
2 iProx will work
3 It's extra outdoor reader, pretty sure it's one external reader per iProx
4 No tags come with iProx
5 Smartcom is compatible but need a trade account to register for Cloud only "DIY option" is GSM-COM
6 Either but neither is Prox
7 This is where you start to seem completely lost - it's just another keypad variant with Prox and yes you'll need a keypad.
8 You haven't got a wireless system, most bells will work but I wouldn't use a backlit one.
9 Again not wireless system and a random Enforcer passive...!?
I think you should seriously consider getting a quote for someone to do it, if you value your time and security.
Your not sure on product types or what is compatible and how it goes together.
Very little of it will come with a manual, some older stock may have a quick leaflet but not the panels.
Whatever your trying to do with this iProx stuff will rely on good programming knowledge to get working, I'd query the design.
