External Telephone Bell

[sparkie415]

HI Can someone please helerrect to terminals 2&5 at the sockets and the ring wire terminal 3 is no longer used. The built in bell / sounder of course still operates.

My question is there must be a outside bell / sounder that can work on just The two fermi als 2&5 without the ring wire.

I have tried to confirm this but with no joy.

Can any please help. Thanks in advance

I am not sure what you are asking, but most modern phones don't require the ring wire on terminal 3, the function is built into their circuit.

Sorry Tom,
Reading my post again i agree its not very clear. What i'm trying to achieve is to have an outside bell / sounder without using the ring wire as i have this disconnected.

As you say most phones have this built into the circuitry, but is there an bell / sounder that you can wire to terminals 2&5 as you would a phone , or simply plug into the phone socket.

I hope this makes more sense (I've got my glasses today)

These bells connect to terminals 3 & 5 so as to utilise the DC blocking "ring" capacitor fitted in the master socket.

If a sounder allows the passage of DC, connecting it to terminals 2 & 5 will cause the telephone line to be permanently engaged.

This situation can be alleviated by fitting a 1.8 μF capacitor in series with one of the wires or fitting an ADSL filter will have the same effect.

If you mean you want a ring amplifier, then there are several types available, some also with flashing lights. You will find a good selection of these on Amazon - https://www.amazon.co.uk/s/?ie=UTF8&...l_8b016arukj_b

Just fit a PABX socket on the extension that will feed the external sounder (assuming it has a BT plug). That was the ring voltage will be generated local so no need to have the ring wire connected from the master socket.
