wires to the Page Sensor port captive screw
connector (use the + and - poles) on the rear
panel of the PVCA 452. Polarity need not be
observed (see image at right).
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 (see
image at right).
NOTE: To enable the PVCA 452 paging
sensor port, use the PCS Configuration
program, available at www.extron.com.

Testing and Adjustment Procedure

To test that the classroom audio is muted when a PA system announcement (a page) occurs:
1.
Turn the classroom program 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. The Paging Sensor yellow LED lights when a PA page is made.
3. Use PCS to adjust the audio sensitivity as needed (see the PVCA 452 Help File in PCS for instructions):
• If the program fails to mute the classroom audio during a page, increase the audio sensitivity.
• If the classroom audio is muted without a page occurring, press decrease the audio sensitivity.
