¡Cover Plate Screwholes – After you have completed installation, these screw- holes accept the screws supplied with your Decora-style cover plate to attach it to the KP 1.

™ Mounting Screw Slots – Use the supplied machine screws to attach the KP 1 to an electrical junction box or plaster ring using these slots.

£ RJ-45 Connector – Insert one end of the RJ-45 connector for the cable connecting the KP 1 to the PA 4000 into this left-facing jack. When the other end of the cable is plugged into the appropriate jack on the PA 4000, the cable carries control signals gen- erated by the KP 1 and the signals received by the optional IR sensor to the PA 4000, and a +12 Volt power supply from the PA 4000 that powers the optional IR sensor, when installed.

¢ 3-Pin IR Sensor Terminal Block – When installing an optional IR sensor, connect it to the appropriate terminals. Connect the sensor’s three conductors to the Ground, IR Signal Output and +12V DC terminals by slightly unscrewing each of the set screws shown, inserting the bare wire end into the downward-facing hole under the set screw, then tightening the set screw. The terminal block is internally connected to the RJ-45 Connector £.

∞ IR Sensor Cutout – If you will be installing an optional IR sensor, punch out this

cutout. See the detailed installation instructions in the next section.

Installation and Connection

The KP 1 should only be installed by qualified personnel. Before installing this device, make sure you are aware of all local building codes and NEC standards that may apply to installing electrical wiring inside the walls of your home. If you have any questions, consult a custom installer.

Step One – Prepare and Install the Wiring

You will need to prepare an appropriate length of CM- or CP-rated Category 3 or Category 5 UTP, 8-pin, 8-conductor wiring. For runs over 250 feet, thicker CL2/CL3, 4-pair, 22AWG wire may be required to preserve signal integrity.

Connect the KP 1 to the PA 4000 using standard T568B Straight Through wiring. Looking at the connector with its clip down and the wires coming out of the connector toward you, numbered from left to right, the typical pin assignments are as shown in Wiring Chart 1 and Figure 1.

Pin #	KP 1 Pin Assignment	Striped Wire Colors	Solid Wire Colors
1	On/Off	White with Orange Stripe	White
2	Volume Down	Orange with White Stripe	Brown
3	Volume Up	White with Green Stripe	Yellow
4	Key Sense	Blue with White Stripe	Green
5	Ground (GND)	White with Blue Stripe	Red
6	IR GND	Green with White Stripe	Black
7	IR Signal	White with Brown Stripe	Orange
8	+12 Volts	Brown with White Stripe	Blue

Either the striped or solid color standards may be used, depending on the type of cable being installed. Make certain that the same color wire is connected to the same pin number at each end of the wire. Make sure that the twisted pairs of wires consist of those attached to pins 1 and 2, pins 3 and 6, pins 4 and 5, and pins 7 and 8.

When attaching the connectors to each end of the cable, strip the outer insulation jacket about 1-1/2" to 2" from the end. The cable is constructed of four twisted pairs of wires. Flatten the wire ends to prepare them for insertion into the connector. Then trim the wire ends to approximately 1/2" in order to leave as little untwisted wire as possible. Fully insert the wire into the connector. Carefully crimp the connector in accor- dance with the connector manufacturer’s instructions, making sure that each wire is securely fastened in the connector and that no insulation is caught in the connector. If using stranded conductors, make sure that there are no loose strands.

Before making any connections to the PA 4000, be certain that it has been turned off and unplugged from the AC outlet.

Home-run the cable from the KP 1 to the PA 4000. Insert the RJ-45 connector on the cable into the RJ-45 Connector £ on the back of the KP 1 until it clicks into place. The connection to the PA 4000 and appropriate configuration of the PA 4000 are described in Step Four.
