Multi-building facilities may have wiring through underground conduit or overhead. You can use an existing spare pair for Valcom paging. Valcom Distributed Amplified Speakers require 2 pairs to operate--an audio pair (tip and ring) and a power pair (-24 Vdc and GND). Both are run with twisted pair CAT 3 or better structured cable. Locate power supplies near the speakers/horns they are powering.
