I have a transformer wired up to my power system but currently use a
battery operated door chime - I now want to go to mains power through
the transformer and also put an extension of the door chime into living
room to be sure we can hear the caller at the door when the TV's on and
loud. How do I do this with the old transformer - which I presume is
working OK.

You'd first have to be certain the ding dong is suitable for AC instead of
DC working and that the voltage is ok. Might be simpler to replace it with
a new one which is.

Some transformers are 'big' enough for two bells - some not. What is the
output - should be written on it somewhere.

-- Thanks for advice Dave - it might be a case of buying a new everything with two bells operation.

The cheap, simple and easy option is to install a modern wireless
doorbell. You can carry the sounder round with you or just use two
sounders (or more) operated from one push - no wires etc. to install.

Good grief.

Sounds like the wiring is already in place.

Doubt it will be as loud as my normal underdome transformer driven bell -
or bells rather, as I've two.

Wonder why everyone seems to suddenly want cordless door bells? Does the
original wiring self destruct? It's not like an alarm or network - surely
most houses are wired for doorbells from new or have it installed at
re-wire time?

Just about the only advantage some have is giving a different sound
for the front and back door. However, that can be done with wired
systems too.

It's technology, innit?

Personally I have wired phones, a wired computer network and two wired
underdome bells like yourself. But people are lazy, and if they can
save themselves 90 seconds by not having to screw wires into terminals
they will. Also lots of people are convinced that anything to do with
electricity (of whatever voltage) is highly dangerous and better left
to the professionals (maybe not such a bad idea in many cases).

The only time I have personally dabbled with cordless bells with so
that my mother could have a bell in the greenhouse at the bottom of the
garden (run via an extender off the main wired bell) - seemed like the
perfect solution.

How long before wired doorbells are brought within Part P I want to
know?

Cheers!

uPVC front doors. If you drill a wooden frame you can always make
good later.

I agree with this.
I found (to my surprise) that the mains transformer in my fuse box
supplying the doorbell did not support the 3 bells I needed,
so I added a Friedland wireless transmitter and 3 Friedland wireless chimes.
This works very well.

I actually use rechargeable batteries in the chimes;
these need replacing every couple of months.
(There is a flashing light on the chime
to show they need replacing.)

Hi Baron,

I'm not sure that I entirely understand what you're asking, but this
might be helpful:
http://tlc-direct.co.uk/Products/VE271.html

I've used one of these to add an additional wireless chime to a wired
system. The transmitter and the wireless chime both need batteries, so
they don't put any load on the transformer. Having the chime wireless
means that it could spend most of its time in your living room, but you
could take it out into the garden in the summer or anywhere else
obscure.

Cheers!

If you are considering a wireless door chime get one where the sounder is a
plug in one (some have a 13 amp thru socket so you don't tie up a socket.

A battery operated one is (in effect) like having a radio receiver switched
on 24hours a day - 7 days a week and the batteries will die. The Sender unit
only uses power when the button is pressed - but the receiver is using power
all the time - waiting - just in case!
