2. Loop either one of the speaker wire leads around the top (open) part of the Sensor, and connect it to the speaker as shown above. Connect the other speaker wire directly to the speaker. Polarity need not be observed.

•For a 25V or 70V system — wrap 5 to 8 loops.

•For a 4/8 ohm system — wrap 2 to 4 loops.

3. Close and latch the top of the Priority Page Sensor.

4. Cut an 18" section from the unterminated end of the supplied blue sensor cable for use in step 8 below.

5. Strip 3/16” of insulation from each conductor on the bare wire end of the blue sensor cable. Do not tin the leads.

6. Connect the stripped leads to the 2-pole captive screw connector on the Priority Page Sensor. Polarity need not be observed.

7. Route the connector end to the PPC 25 Controller, and plug it into the PAGING SENSOR receptacle.

8. Connect the 18” 2-conductor cable (from step 4) from the RELAY OUT port on the PPC 25 Controller to the mute control input port on the audio amp or switcher to be muted during a PA system announcement. Polarity need not be observed.

When integrating the PPC 25 into a PoleVault System:

1. Connect the 18” cable (from step 4 above) from the RELAY OUT port on the PPC 25 Controller to the MUTE and GROUND pins on the PoleVault PVS 204SA VOL/MUTE port. Polarity need not be observed.

2. Use the included cable assembly (PN 27-576-01LF) to power the PPC 25 from the PVS 204SA power supply. The PPC 25 must be mounted near the PVS 204SA and its power supply.

			POW
			ER
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.

To Power Supply

3. If the PPC 25 fails to mute the classroom audio during a page, turn the SENSITIVITY adjustment clockwise.

4. If classroom audio is muted without a page occurring, turn the SENSITIVITY adjustment counterclockwise.
