Hello everybody and Happy New Year to the 1A2 world team.

I have several WE 1A2 phones (2565 hkms and just received "new" big Call Director). I try to use theses phones on the French network (on a single line at home) but the ringers or buzzers never works. I suppose there's different ringing voltages than in the USA (I can see 40V on rings when I receive calls). I can see this voltage from the black and red wires of the ringer (that means they are well connected) but nothing happens on the ringers or buzzers, I tryed everything... Otherwise, everything is OK, I can call and the rest of the phone is OK.

Any ideas ?

The ringer was designed to work on +/- 90V AC @20Hz, the buzzers on either 10V AC (Blue wires) or 18V AC (White wires). Apparently the French systems voltage is completely different. You could try adjusting the bias spring on the ringer to see if you could get any action on it at all, or why not just try replacing the American ringer with one from a French Telephone?

40 volts is barely enough voltage. These are designed to work in the 77-105 volt range. You may be able to tinker with the bias spring on the ringer to loosen the clapper. Aside from that, it's going to be difficult to make them ring on such a low voltage.

Well Ed, I'm glad we think alike.

Talk about split second precision! Sam beat me to it.

Just barely, apparently.

I've never heard of the French system supplying such a low ringing voltage. Are you sure the meter you were measuring with is accurate at frequencies much lower than 50Hz, and with 48 to 50V d.c. superimposed?

If the ringing voltage really is that low, could it be a long line which is already heavily loaded by other ringers?

Thanks for your reply.
I'm on the 50V range of the voltmeter and see 40V but on the AC !! Nothing if I check with the DC of the voltmeter. On the 2565, there's a very small ring, that confirms a too low voltage, the one on the Call director don't move at all.

Most of all, I'd like to ear the buzzer. I have the one installed on the Call director, and other one directly purshased new, but none is working. I remember that the one I purshased alone was given for high voltages... If the one on Call director is given for 10V AC, does it mean that I burned it when trying on the line with 40V ?

There's only one phone on the network.

I don't know if the voltmeter is accurate for frequencies lower tha 50Hz, I must say that I don't have a large knowledge on that...

Try unplugging the American phones, plugging in a French phone, ringing it and measure the voltage then. It's possible the American Ringers are loading down the line (wrong frequency?)
