I'm probably the one that posted about it 10 years ago as I had one I was setting up on my home system. You might find posts under my user name if they aren't archived...
But yeah when any station goes off hook the intercom key lights up solid on all sets. When the intercom is activated to a station the interrupter is activated and the key light for the called station flashes where the other stations stay solid. I have mine set up to use buzzers so the called station buzzes once and the light flashes. I don't remember if it times out after a period of time. If you search "dmntn7" on youtube I have a short video of how it works.

I did have problems initially with the unit working properly. I think the relay contacts had oxidized. Once everything was set up and I could exercise it it worked fine and still does although I never use it.

It is kind of fun being an obscure unit.

ps: I dont have any docs other than the label on the box itself. I thought I had something on it but I looked and dont.

I do recall your original post and that sparked my interest in getting one. I knew that it was very very rare and most likely that I would never would find one. After many years of searching, patients paid off and found one.

Very obscure and I would call it oddware...
