The Rittenhouse door intercom answering system system was installed in 1978. It is not functioning well. Do you have a newer replacement for it that would still have the doorbell and intercom system? Does a new unit come with the exterior speaker?

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.
