FAKE PHONE RINGS
Mon, 15 Aug 2005, 11:54 amAt Busselton Repertory Club, we would like to make a modern phone "ring" ("brr-brr") on stage. We have a device that we crank to ring the bells on the old-fashioned phones.
Does anyone know how to do it? If it has to be built from a diagram or a spec, we can get access to technical people that should be able to help us. I will be in Perth in late August/early September if a personal visit will help.

Hello Bill
Australian telephones operate on 50 volts dc (as set up by the PMG) and the ring voltage is 60 volts ac.
You can use a 60 volts ac transformer as a substitute for a ring tone generator.
Pins 2 and 6 on the telephone socket are used. In the 600 series telephone socket (the large cream 6 pin square ones) the bell is fed on pin 3 and there should be a link from pin 2 to pin 3, which may be removed for an external bell.
Use a working telephone so when the actor lifts up the handpiece from the cradle, the phone bell stops ringing. The actor will get a loud buzzing sound in the earpiece but by this stage you should have stopped the ringing volts.
Hope that helps.
