Notifier Audio System Help

We are using AA100 for this project. There are two risers Tone & Page.
I need your help as my head is not going along. We are using AA-100 with DVC. We have two riser Tone & Mic/Page.
We are using XP-6CA for hallway and suite speaker circuits and XP-6RA to shift between Tone & Page.
My concern is if we are wiring hallway and suites to XP-6CA and power from XP6-CR then how can we supervise power for XP-6CA cards.

If youre using a DVC, why do you need 2 risers?
You could just set the priority level higher for 1 or the other in programming.
If you set paging higher than tone, when you go to page, it will automatically cut the tone.
