MOUNTINGANDWIRING THE SAFETYREVERSING SENSORS
Mounting:
• Slide a 1/4"-20xl/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.
OptionA -/nsta//ation WithoutPre-Wiring:
• Run the bell wire from both sensors to the garage door opener.
Attach the wire to the wall and ceiling with the staples
(Figure 6).
Option B - Pre-Wired /nsta//ation:
If your garage already has wires installed for the safety reversing
sensors, follow the instructions below:
• Cut the end of the safety sensor wire, making sure there is
enough wire to reachthe pre-installed wires from the wall
(Figure 7).
• Separatethe safety sensor wires and strip 7/16 inch (11 mm)
of insulation from each end. Choose two of the pre-installed
wires and strip 7/16 inch (11 mm) of insulation from each end.
Make sure that you choose the same color pre-installed wires
for each sensor (Figure 8).
• Connect the pre-installed wires to the sensor wires with wire
nuts making sure the colors correspond for each sensor
(Figure 9).
CONNECT TO GARAGEDOOROPENER:
• Strip 7/16 inch (11 ram) of insulation from each set of wires.
Separatewhite and white/black wires sufficiently to connect to
the opener quick-connect terminals. Twist like colored wires
together. Insert wires into quick-connect holes: white to white
and white/black to grey (Figure 10).
