Q: Have doorbell wired to transformer. Is it possible to add an extension bell please. - Anthony

A: Whether a doorbell transformer can support an extension bell depends on what kind of power it outputs, as well as the power drain of the second bell, the length of the wire and other consideration. Your best bet is just to give it a try and see if it works. If it doesn't, you can always try to find a more powerful transformer at your local DIY store.
