Manual
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 
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 (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
