B. Add Background Music
If there is not a background music input on the paging amplifier, the FXI-1A relay contacts can be
used as shown below to add a background music source. This application works with all paging
input types (FXS, FXO, and VOX), and the music is suppressed during paging.

C. Page Trigger
If the FXI-1A relay contacts are not being used for adding background music (as shown above),
they can be used as a page trigger. Connect the common and normally open contacts to the paging
amplifier's Page Trigger input. The contacts will provide a contact closure when paging is active.
