Nutone IMA 4006

Bought a new house with an installed Nutone IMA 4006 intercom system. Everything works except for the door bell. After checking the wiring I found the speaker and push button at the door was wired correctly. I opened up the main control unit and found the 2 push button wires had been disconnected. Question is.... where should these 2 wires connect in the main control panel? Once I can find this out it will allow me to troubleshoot the entire circuit including the transformer. Thanks

You can contact Nutone tech support at 888-336-6151 during normal eastern time business hours.
As I recall, the IM-4006 is an older intercom and they don't have any specs on their web site.

This intercom has a door bell module/board that mounts perpendicular to the main board toward the left side that has 2 screws on it to accept the bell. I am looking for a schematic for this unit in order to repair the bell module and would appreciate hearing from anyone that has one.
