Wiring new doorbell and chime?

[chris101]

I want to replace my wireless doorbell and chime system and not sure how to go about it....

I have located the existing location of the chime unit and it has two set of two wires -

1. 2 Wires that come from the (I assume) the consumer unit that are meant to go into the chime

2. 2 wires that go from the chime to the doorbell.

Not sure how they are supposed to work and where they have been connected into the 'consumer unit'?

The wires are skinny white wires and have no colours on them.

Any ideas what I need to do?

Thanks

Does not sound wireless to me?
Have you the make/model of the unit/system, that would hopefully offer info that can be worked on.

Have you checked if any of the wires going into chime unit are live ?
Does the chime unit still work when the door bell is pressed?
Is there a switched spur box or socket nearby that could have been the live supply to the unit.

The chime unit could have been fed by a transformer unit hence the white wires, popular in the 60`s

As above. If it's got wires it ain't wireless!

Not more semantics.

If so, then those from the consumer unit will be from a transformer, the others to the button at the door.
Wiring is to take one wire from the 'consumer unit' end and one from the button end and connect them together.
The two wires that are left (one from each side) are connected to the chime or bell.
This assumes that the transformer and button are still working.

Sorry I was not clear -
I installed a friedland wireless doorbell and wireless chime 3 years ago as it seemed like the best solution at the time.
The wires I mentioned in my initial post was installed by the builders in readiness a wired chime and doorbell however I chose the wireless route in the end...

That is exactly the wire!

How do I know the builders have connected it to a transformer and not directly from the consumer unit?

Usually the transformer is located next to, and sometimes inside, the consumer unit.
Post a pic of the cu and its surroundings.

So a little confused now...

Here are the pics of behind the doorbell, where the chime will go and the consumer unit....

Not what I expected!
I especially thought there would only be two wires behind the doorbell not 2 sets of 2...

Who clipped that black cable in top right picture?

Good job it wasn't more twisted.

Which black cable, there are a few?
All done by the builders...

Any ideas guys how I will wire the bell and chime?
Just to add - I have a 2nd chime unit in the kitchen area.
I have just checked behind it and there are 2 wires located there as well....

So I assume the way it is setup is as follows -

Kitchen Chimes to Doorbell?
Doorway Chimes to Doorbell?
Consumer Unit or other source or Doorway Chimes?

There doesn't seem to be a transformer near the consumer unit.

Do you own a multimeter?
