Optional Accessory Installation — PPC 25

The example below is the installation of the optional accessory Priority Page Controller and Sensor (PPC 25).

The Priority Page Controller momentarily silences classroom audio whenever a page is made from a public address (PA) system.

For detailed information, refer to the PPC 25 Installation Instructions, supplied with the device.

NFollow all local fire and safety code requirements for installation and anchoring.

1. Connect sensor to paging speaker

a. Open the top of the Priority Page Sensor.

b. Loop (only) one of the Paging speaker wire leads around

the top (open) part of the Sensor. Either speaker wire

will work. Leave the other speaker wire connected

directly to the Paging speaker. Polarity need not be

observed.

Open the Sensor

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

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

c. Close the top of the Priority Page Sensor.

a.Cut an 18" section from the unterminated end of the supplied blue sensor cable, for use in step 3.

b.Connect the bare wire end of the supplied blue sensor cable to the 2-pole captive screw connector on the Page Sensor. Polarity need not be observed.

c.Route the connector end of the sensor cable to the PPC 25 Controller and plug it into the Paging Sensor port.

3. Connect the PPC 25 to the switcher

a. Connect the 18" cable made in step 2a to the Relay Out port on the PPC 25 Controller and to the mute and

ground pins on the PVS 204SA Vol/Mute port. Polarity need not be observed.

b. Use the included power supply 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.
