Question About M&S Systems Intercom System N 150
The doorbell for my M and S intercom model # N150 ...

The doorbell for my M and S intercom model # N150 no longer works. The intercom and radio work. There is no voltage detectable in the wires to the outside doorbell button. Is it a blown transformer? Can I purchase a transformer for this old model, installed in 1990?
