It's a fairly elderly Byron doorbell. The Bell push has a battery (I've bought a pair of new ones so there's a spare) and the Bell unit plugs in to any 13amp socket, and has it's own socket so you can plug something else in - you don't 'lose' a socket. It can be put wherever you choose. It's tested and working.
Drop me an email saying why you'd like it please,
Thanks for looking, ColinMud
