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.
