I will start off explaining the scenario. Three storey house. One doorbell sounder on ground floor with transformer. It's for my friends Mum who's quite deaf, she can't hear the doorbell in the living room on the first floor, she wants another sounder in the living room. I bought another doorbell with the same terminals OF, 1,2 3. Question is this possible? would the transformer be enough to run both or maybe one sounder should be run on batteries (which doesn't sound right).
