Connect the Priority Page Sensor to
the Paging Sensor port on the switcher
5. Close and latch the top of the Priority Page Sensor.
Reconnect the speaker cable to the speaker.
6. Strip 3/16 inches of insulation from each conductor on the
bare wire end of the remaining blue sensor cable. Do not tin
the leads. Feed the wire into the junction box (clamping it
down if necessary) and connect the wires to the 2-pole captive
screw connector on the PVS 305SA. Polarity need not be
observed.
7. If a junction box is being used in a plenum space, ensure the
sensor and all wires fit inside the box (as shown at right). All
cables leaving the box must be plenum rated. Tighten the
cable clamp and secure the lid to the junction box.

To enable the switcher’s paging sensor port, use the
MediaLink Switchers Configuration program (for MLS and
PoleVault Switchers PVS), available at www.extron.com.
Testing and Adjustment Procedure
The fully installed system is shown below To test that the
classroom audio is muted when a PA system announcement (page)
occurs:
1. Turn the classroom audio on.
2. Speak into the PA system microphone. The classroom audio
should be muted while the PA system page occurs and be
restored when the page ends.
3. If the program fails to mute the classroom audio during a
page, turn the Sensitivity adjustment, on the front panel of
the PVS 305SA, clockwise.
4. If the classroom audio is muted without a page occurring,
turn the Sensitivity adjustment counterclockwise
Ensure the sensor and wires fit
completely inside the junction box
before attaching the cover
