MOUNTING AND WIRING THE SAFETY SENSORS
• Slide a 1/4"-20x1/2" carriage bolt head into the slot on
each sensor. Use wing nuts to fasten sensors to
brackets, with lenses pointing toward each other across
the door. Be sure the lens is not obstructed by a bracket
extension (Figure 5).
• Finger tighten the wing nuts.
Recommended Wire Routing
1. Using insulated staples, run the wires from both sensors
to the rail at the door header (Figure 6).
2. Run the wires through wire clip at the top of the rails.
NOTE: If your access door is near the garage door, you
may choose to install the door control at this time and
run the door control wire along the rail with the sensor
wires. If you choose this option, follow instructions 1-3
on page 20.
