PPC 25
Priority Page Controller
The PPC 25 mutes classroom audio during a page from a public address system. The sensor connects to a PA speaker lead and detects current flow when a PA announcement is initiated. The sensor signals the controller to close its output relay which sends a mute signal to the classroom audio device. The output relay can be connected to any product that has a digital input or contact closure mute control, such as the Extron MLC 104 IP Plus MediaLink® Controller, PVS 204SA PoleVault® Switcher, or MPA Series and XTRA™ Series power amplifiers.
Note: The PPC 25 and sensor cable are UL 2043 plenum rated, allowing for installation above a drop ceiling. The PPC 25 Sensor assembly must be installed in a sealed enclosure, such as the included metal junction box to meet the plenum rating requirement.
