PoleVault Systems Installation • Optional Accessory Installation
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 Priority Page Controller fails to mute the classroom
audio during a page, turn the Sensitivity adjustment, on the
rear panel of the controller, clockwise.
4
. If the classroom audio is muted without a page occurring,
turn the Sensitivity adjustment counterclockwise
5
. If the classroom audio is muted for too long a time after a
page, or is restored too early, check the Time DIP switch
settings. A short time delay is necessary so that if the PA
system announcer pauses briefly during the announcement,
the classroom audio is not restored prematurely. Set the
switches so that the output relay will remain closed for a set
time after a PA announcement has ended.
