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.
• 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.
2. Connect sensor to the PPC 25
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.
