The PPS 25 Priority Page Sensor works with Extron Classroom AV Systems to automatically mute classroom audio during an announcement from a public address system. The sensor connects to a PA speaker lead and detects current flow, signaling the switcher to mute classroom audio for the duration of the announcement. The PPS 25 is compatible with PVS 305SA IP, PVS 405D and PVS 407D PoleVault switchers.
Note: The PPS 25 must be installed in a sealed enclosure, such as the included metal junction box to meet the UL 2043 plenum rating requirement.
