Add a second doorbell - compatibility?


I have a 1080 doorbell (T8222) with mini-repeater unit, and want to add a second doorbell for back entrance which is in range of the existing unit.

Is it possible to add a second T8222 using the same extender/chime unit?
Is it possible to pair a new model T8200 to the original extender/chime station?

Thank you!
