Hi les,

Firstly welcome to the forum.

If you have a current linebox / master socket the applicable configuration for connecting a ringer is 3 x wires (although some non approved imports can be two wire).

It is difficult to answer you query without knowing where the non connected wires go to. Ideally, a clear picc'y of the internal wiring oor af a rough sketch may help.

Am I reading correctly that there are two red wires, one of which is connected and the other isn't? If there were a blue wire, I would have advised connecting it to the position adjacent to the red one as a first try.

Yes that a bit clearer Les,

There should be two internal wires from the bell coils

One should should connect to the existing white wire termination.

The other bell wire goes to the blue of the line cord but this has had the lug snipped off so you will need to make a joint & tape up rather than connecting to anything else.

Should work provided the other end of the line cord has a standard BT plug on the end which has not been tampered with.

However, this extra bell may upset the REN balance of you internal phones if you already have others phones plugged in as well. In other words, none will ring on an i/c call.

Ignore my previous post. For some reason I was thinking you were referring to connections at the far end of the line cord. I really ought to desist from posting when I'm tired!

As Roger says, if you can find a terminal connected to the end of bell coil not connected to the terminal with the white wire, the blue wire need to connect to it - as long as there is a connection back to the ringing capacitor in the master socket.

Alternatively, if the end of the bell coil is connected to a capacitor, connect the other end of the capacitor to the same terminal as the red wire, and leave the blue wire unconnected.

This phone is probably made for non-UK ringer circuits.
The strap between Ø9 and Ø10 is probably made for letting the ringer work on the 2 wires.
Something may have been modified, or disconnected by a previous owner in hence to not get to high REN load on the line. Moving the white wire from 11 to 12 or 13 may get it ringing, but you will probably not be able to speak, that test will show us where the connection between 11 and?? was when it was used in non UK systems.

When we know that we may ind out where you should put your third wire.

Does this have the green circle and "BABT approved" label underneath, or is it definitely a grey import?
