PPC 25 Installation Instructions, cont’d
9. Strip3/16"ofinsulationfromeachconductoronthebarewireendoftheremaining
blue sensor cable. Do not tin the leads. Connect the wires to the 2-pole captive screw
connector on the Priority Page sensor. Polarity need not be observed.
10. Route the connector end to the PPC 25 controller, and plug it into the Paging Sensor
receptacle.
11. 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.
12. Use the included Y-shaped cable assembly to power the PPC 25 from the
PVS 204SA power supply (as shown below). This cable assembly allows
both devices to be powered from a single power supply.
Testing and Adjustment Procedure
The fully installed system is shown in the figure to the right. 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 PPC 25 fails to mute the classroom audio during a
page, turn the Sensitivity adjustment, on the rear panel of the
controller, clockwise.
4. If classroom audio is muted without a page occurring, turn the
Sensitivity adjustment counterclockwise.
