Installation: for 3-Way / 4-Way operation - Existing/Alternate
Note: A 3-Way / 4-Way system, by definition, means two or more existing wall switches which operate one single light (can be multiple
lights if all come on together). In this alternate installation instruction, the XPSS switch may not work well due to longer traveler wires
between multiple switches. The XPT2D Transmitter will work over the longer wires between multiple switches.
The XPT2D Transmitter provides ON/OFF and Bright/Dim.
1. Turn power OFF at Circuit Breaker.
2. Pull-out the existing 3-way wall switches from the two switch boxes.
3. Remove the common-side wire (by itself) from the two switches. In one switch box, that single wire is HOT, in the other switch box, that single
wire goes to the light.
4. With Breaker ON, determine which wire is HOT. Use a voltmeter and measure between ground and each wire individually. One will read 120V,
the other 0V. With Breaker OFF, mark the wires as to which one is HOT and which one goes to the light.
5. The Alternate XPT2D Transmitter is installed in the switch box which has the HOT wire. The Master Switch is installed in the switch box that has
the wire that goes to the light.
6. With Breaker OFF, remove the existing two wall switches. Three wires (minimum) remain protruding out of each switch box. At the Slave switch
box, one is HOT, the other two wires are the traveler wires. They may be the same color, normally they are different colors. At the Master switch
box, one is the Light/Load wire, the other two wires are the traveler wires. They may be the same color, normally they are different colors.
7. With Breaker OFF, install the Alternate XPT2D Transmitter first. The HOT wire goes to the XPT2D Black wire bundled with one Traveler wire
(this will carry HOT to the Master Switch), the White wire of the XPT2D is connected to a White Neutral Wire in the same box.
8. With Breaker OFF, install the Master Switch second. The One HOT Traveler wire goes to BLACK wire. The Light/Load wire goes to BLUE wire.
9. Re-check all connections, Turn power ON at Circuit Breaker. Slide the Power Cutoff Switch to ON position.
10. Press Master Switch paddle once, the light should turn ON. Press paddle again, the light should turn OFF. Press the alternate XPT2D
Transmitter "ON" position once, and the light should turn ON. Press the alternate XPT2D Transmitter "OFF" position once, and the light should turn
OFF. Additionally you can press the DIM or Brighten rocker on the alternate XPT2D Transmitter to control intensity after you turn the load on.
11. You are now ready to control the switch with an X10 Remote Control Module: Desktop, Wireless Handheld, Security Panel, etc. The default
address is "A1" for both switches. If you wish to change the Address Code, the Code Dials are behind the paddle on the Master and Keypad on the
Transmitter. Remove the paddle with a small flat screwdriver applied to the side of the paddle at the center fulcrum point. Insert screwdriver in
small gap space between switch plate and paddle and flip the paddle up from its side.
Remove the Keypad, with fingers pulling from bottom, to change the XPT2D Address Code.
12. Attach the switch cover plate.
Soft Start On and Fade Off plus Bright / Dim Control:
On/Off - A short paddle press causes the Switch to come on at full dim and fade up to the full intensity, another short paddle press causes the
Switch to fade off (brightening to full intensity and fading to full off takes approx 3 seconds each direction).
Dimming from ON - Press and hold to achieve the dim level desired then release. When released, the direction of dimming is toggled, (i.e.
next press and hold will cause the switch to brighten). A short paddle press from any dimmed level will fade off the Switch. A dimmed Switch
will resume the level of intensity when turned back on
Note: If you would like the Switch to always resume full intensity when turned on, then press and hold the paddle until the Switch attains full
brightness before releasing. Then a short paddle press will fade off.
Additionally, any X10 Controller can remotely operate the full functions of the Switch.
Note: You can use additional XPT2D Wall Transmitter Switches to augment EXISTING 4-Way or greater systems. Continue using the existing
traveler wires to carry HOT and Neutral to the additional existing Switch Box locations. Then install the XPT2D in those additional boxes with
traveler wires, connecting to HOT and Neutral.
