I came to the Paging forum for a new problem I have, only to realize I never posted the resolution to my problem listed above. My apologies. So before I get into my next issue, here is what I found.

There were a combination of little things that all compounded the problem. There was at least one poor connection at the page horn. Once we had the lift out and found this, we checked all the new horns. After double checking all the wiring we also had the volume controls way too low on the new horns. We are using the second V-2001A for the new horns, and had to turn it up some. After a lot of tweaking, we have a working system.

Thanks for the suggestions.
