Valcom powered speakers and horns require two twisted pairs to operate. 1 pair provides the audio signal, the other pair provides 24 VDC to operate the internal amplifier. Wire can be power limited permitting installation in plenum ceilings and exposed raceways. Consult your local wiring or building inspector for approvals and recommendations.
