WIRE THE SAFETY REVERSING SENSORS
The receiving sensor has a shorter length of wire and should be mounted on the
same side as the operator. If sunlight interference occurs, the receiving sensor can
be moved to the other side of the door opening by cutting the wires of the sending
sensor and the receiver sensor and reconnecting the wires.
1. Run the wire from both sensors to the garage door opener. Securely affix
the wire to the wall and ceiling with staples (not provided).
2. Strip 7/16 inch (11 mm) of insulation from each set of wires. Separate white
from the black the wires. Twist the white wires together. Twist the white/
black wires together.
3. On the garage door opener, push the tab with a screwdriver tip to insert the
white wires into the white terminal and the white/black wires into the grey
terminal.
