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.

NTo 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
