Second door bell connection

[Rudie]

Hi

I want to add a second doorbell chime with 1 button. The one that is currently there is as in the picture but not sure what I can run off this. I have read some posts about using 1a transformers and think this one is the same. So is it either a case of replacing the transformer for a 2a and then getting a like door chime and connect in series?

Thanks in advance .

There is no picture. Don't connect the door chimes in series, connect them in parallel. I would not replace the transformer either. The short tome it will be supplying power, a few seconds occasionally, is not going to do it any harm even if it is more than 1 amp.

Sorry pic attached. So if I get a similar chime and connect that in parallel that would do the trick? I wouldnt need to wire up to the door bell switch?

Now that you have a picture up I see it is a door chime and transformer in one box. You may be able to add a stand alone chime to this connected to the right hand two terminals. As the transformer is only 10.3 v, whereas chimes are usually 12v this may not work too well however.

Hmmmm. Don't no one sell door chimes to be connectwd up like this? I thought it would be a common thing to have 1 door button and 2 chimes ? I'm not after a wireless one though as I tried this and had a mind of its own!

You may be able to add a stand alone chime to this connected to the right hand two terminals.

Or even the left hand 2 terminals!

10.3V is a bit odd. The model you have can be bought for around £12 you could buy another one and connect the left hand 2 terminals to the same left hand 2 terminals on the new one, and ignore the second transformer. The existing transformer may however be designed right down to only just be able to power the one chime in order to save money, after all that is all it was designed for.

It is also likely a normal 8V chime will work fine.

The proper way is to rip the existing one out, fit a separate transformer and 2 new matching chimes/bells/buzzers.

So remove transformer from this one. get a separate transformer to power this and the new one - but what power does the transformer need to be?

You would need to replace the old chime too, as you are unlikely to find a 10.3V transformer. A door bell transformer with a voltage to match the chimes and a rating of 1Amp will be fine.

Here is a good place to look.

Thanks. So assume I will need:

1 x TC TR7 Transformer 4/8/12v 1 Amp for Door Bells & Door Chimes
2 x VE230 Big Ben 2 + 1 Note Door Chime

Plus some bell wire.

Yes.

Looking at the instruction manual, to add the second chime it looks like you need to connect:
T3 on chime 1 to T3 on chime 2
and
F2 on chime 1 to F2 on chime 2

I found this transformer today, will this one support 2 chimes?

Thats not a chime, thats a basic ding dong, its just a spring loaded solenoid, that pulls in and springs out, a second battery operated ding dong is what you need and DONT fit the batteries, link to the existing with 2 core and let them both use the transformer in your first unit, i assume that transformer is wired up

Thanks 333rocky333. So you reckon i just need 1 new chime linked up to the current chime? I dont need to replace my existing chime?
