Make a Built-in Light an X10 Light Have you ever thought about automating a built-in light or appliance fixture, such as a ceiling fan? Now you can do so without having to change the switch! Control a built-in light with X10 commands using the HomePro Fixture Relay Module, which wires in discreetly and permanently to any light or appliance. This in-line fixture switch mounts to the inside of the lighting or appliance fixture using the included self-adhesive tape and attaches to your wiring, making it possible to control the unit via X10 or extended address commands using an X10 transmitter to communicate with the module. Since the module operates using a relay, no dimming capabilities will be possible on this light. Step 1: Installing the Fixture Relay Module As with any installation involving electrical wires, make all connections with the power OFF in order to avoid possible injury or damage to the device. To install the Fixture Relay Module, strip 3/4 of an inch of insulation from the ends of the conductors and make connections as shown in the installation manual wiring diagram. Clean the mounting surface, remove the protective film from the included adhesive tape and firmly press the module in place. Step 2: Configuring the Address and Accepted Commands This X10-compatible module accepts all standard 256 X10 addresses, but it can also be programmed to any of the extended X10 addresses, which number up to 4096 addresses. To set the light's or appliance's address, press and hold the configuration button for 3 seconds and release. Using a transmitter, transmit the desired address twice in succession. The status LED will blink twice. This in-line module responds to ON, OFF, ALL LIGHTS ON, ALL LIGHTS OFF and ALL UNITS OFF commands. To enable each command, transmit the command twice in succession. With two-way powerline communication, the Fixture Relay Module will even respond to relay status requests. Step 3: Confirming the Signals Using a transmitter, transmit the Fixture Relay Module's address and any configured commands to ensure the module controls the load in response to remote control. That's it! Now you can control this light or appliance using any X10 transmitter.
