Privacy Lights Outputs
Two ports are provided to interface with privacy lights panels. They may be
designated to 2 different zones and should be home run from the controller to
the privacy panel. See Figures 7-8.
5 VDC outputs are available to indicate sound masking is active on a specific
zone as indicated by privacy lights. The functionality is as follows;
Privacy 1 - Connect the positive lead of a privacy sign to Pin 1 and GND (observe
polarity). Select a zone in the Zone Name dialog to associate the Privacy light to
a specific sound masking zone. When the zone is active (above -20dB in level)
the privacy light will illuminate.
Privacy 2 – Same behavior as indicated above with privacy sign connections to
Pin 2 and GND.
