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 IP.
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.
NOTE: To enable the switcher’s paging
sensor port, use the MediaLink Switchers
Configuration program (for MLS and
PoleVault Switchers PVS), available at
.
Testing and Adjustment Procedure
The fully installed system is shown below.
To test that the classroom audio is muted when a
PA system announcement (a page) occurs:
1. Turn the classroom audio on.
2. Speak into the PA system microphone. The
classroom audio should be muted while the PA
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 IP, clockwise.
4. If the classroom audio is muted without a page
occurring, turn the Sensitivity adjustment
counterclockwise
