Extron Electronics PPC 25 Installation - Manual (Page 3)

3 PPC 25 Priority Page Sensor • Installation Instructions
4 . Remove the outer protective jacket from the speaker
cable to expose the two speaker wires from the sensor
to the speaker (as shown at right). Do not remove
the inner protective jackets that cover the individual
wires.
If the sensor is to be located in a plenum space, feed
a loop of one of the exposed speaker wires through
the cable clamp into the junction box. The other
wire can bypass the junction box.
Open the top of the Priority Page Sensor.
5. Loop one of the speaker wires tightly around the top part of the sensor. Polarity need not be observed.
N Loop only one of the speaker wires around the sensor cover. Do not loop both wires.
The other speaker wire must bypass the sensor and connect directly to the speaker.
• For a 25 V or 70 V system, wrap 5 to 8 loops.
• For a 4/8 ohm system, wrap 2 to 4 loops.
6 . Close and latch the top of the Priority Page Sensor.
7 . Reconnect the speaker cable to the speaker.
8 . Cut an 18" (45 cm) section from the unterminated end of the supplied blue sensor cable
(see the figure above). Use it to connect the Relay Out port on the PPC 25 Controller to
the Mute and Ground pins on the PoleVault PVS 204SA Vol/Mute port (see the figure
at right). Polarity need not be observed.
N Do not connect either of the outputs from the PPC 25 Controller to the 10V
port on the PVS 204SA switcher. The output relay must connect only to the
PVS 204SA switcher and not to a MediaLink controller.
