5.Close and latch the top of the Priority Page Sensor. Reconnect the speaker cable to the speaker.

6.Strip 3/16 inches of insulation from each conductor on the bare wire end of the remaining blue sensor cable. Do not tin the leads. Feed the wire into the junction box (clamping it down if necessary) and connect the wires to the 2-pole captive screw connector on the PVS 305SA IP. Polarity need not be observed

7.If a junction box is being used in a plenum space, ensure the sensor and all wires fit inside the box (as shown at right). All cables leaving the box must be plenum rated. Tighten the cable clamp and secure the lid to the junction box.
