Adding extra chime to mains wired doorbell

[Groove Rida]

Hi
I have a mains wired doorbell with the chime in the hallway. Parents are elderly and dont hear the bell all the time. I want to run two wires from the hallway chime into living room and add another chime there. Does the new chime need to have built in transformer does it not require it?
Current set up is a transformer by the fusebox and the chime has one wire to it and another to the push button. One wire from the push button the transformer to complete circuit.

To be honest with all of the messing about wiring etc. I would go wireless

Only 2 wires and a chime is about £10 -£12 job done

Does any1 know if the second chime has to have built in transformer or not?

One transformer for two chimes

But

I have found that many bell transformers don’t have enough output for two bells. So, you may find that you need to replace the tranny. Try it and see if it works, but I too would go for a wireless jobby.

There are probably electronic chimes available that draw very little current to operate, which would probably overcome the possible transformer output problem.

I solved a similar problem on one occasion, by replacing the chime with a large fire bell (customer's son's suggestion.)

What if the second chime has a built in tranny. Will that work?

Not unless you have 230 as well as wiring it to the existing one.
