Byron 776 with TWO wired Ring Doorbells

Hi Guys, I recently purchased a wired Ring Doorbell, great bit of kit, so purchased another for the front of the house. This cable is run around 10 meters away from the Byron 776 unit. My first doorbell works fine, however, when wiring the second using the same 0 and 3 terminals I got a loud buzzing, sounded like arcing. when using other terminals the second ring unit would not power up. Does the Byron system have the ability to power both units simutainiously? If so, how would I go about wiring this up? Any help would be greatly appreciated! Cheers :slight_smile:
