INSTALL THE SAFETY REVERSAL SYSTEM (CONTINUED)
MOUNTING AND WIRING THE SAFETY REVERSING SENSORS
Mounting:
1. Slide a 1/4"-20 x 1/2" 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).
2. Finger tighten the wing nuts.
Option A - Installation Without Pre-Wiring:
1. 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 Installation:
If your garage already has wires installed for the safety reversing sensors, follow
the instructions below:
1. Cut the end of the safety sensor wire, making sure there is enough wire
to reach the pre-installed wires from the wall (Figure 7).
2. Separate the safety sensor wires and strip 7/16" (11 mm) of insulation
from each end. Choose two of the pre-installed wires and strip 7/16"
(11 mm) of insulation from each end. Make sure that you choose the
same color pre-installed wires for each sensor (Figure 8).
3. Connect the pre-installed wires to the sensor wires with wire nuts
making sure the colors correspond for each sensor (Figure 9).
CONNECT TO GARAGE DOOR OPENER:
1. Strip 7/16" (11 mm) of insulation from each set of wires. Separate white
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).
