OPTION B - PRE-WIRED INSTALLATION
1. Cut the sensor wires, making sure there is enough wire to reach the pre-installed wires from the wall.
2. Separate the sensor wires and strip insulation from each end. Choose two of the pre-installed wires
and strip insulation from each end. Choose the same color pre-installed wires for each sensor.
3. Connect the pre-installed wires to the sensor wires with wire nuts making sure the colors correspond
for each sensor.
4. At the garage door opener, strip the end of the wires previously connected to the sensors. Twist the
like-colored wires together.
5. Using a screwdriver, push in the terminal tabs, and insert the wire color connected to the sensor's
white wire into the white terminal. Insert the other wire color connected to the sensor's white/black wire
into the grey terminal.
