My manual says 4-8 Note Chime Models (534, 535, 552, 577, 618, 633). I don't know which one I have. It has long chime tubes and a clock on top. The door bell works great, but the clock doesn't.

Is there a new updated unit (with new bells & whistles) that can use the existing wiring and wall recesses of the old units. If so, where can I get them and what would be a ballpark pricing? Thanks

A plunger on my 50 year old door chime is not returning to the rest position when the door chime is not activated. The consequence is a continuous buzz and erratic operation when the button is pressed.Have I provided sufficient information to diagnose the ease of repair?Thank you.Jim—> …Purchase or Repair: Ticket Image...

I have an older system, it was still working but when a water pipe broke behind my kitchen wall, it soaked the unit and ruined it. I want to know how much it would cost to have it replaced so I can get back the intercom and music function. Thank youAlbert Brien
