    I am not an alarm professional but I would not double up on PIR. Door contacts are a maybe - I may double up on contacts that are on say double doors - one on each side, for example.

    Do you have a sketch of how the contacts / PIR are laid out? Do you need all eight contacts?

    Have you already got a Rio expander installed ?
    You can have multiple devices on a zone but it is not advised. Screenshot_20210121-102324.png
    Wiring diagram shows how this can be done.
