INSTALL THE SAFETY REVERSAL SYSTEM (CONTINUED)
INSTALLING THE BRACKETS
Be sure power to the opener is disconnected. Install and align the brackets so the
sensors will face each other across the garage door, with the beam no higher than
6" (15 cm) above the floor. They may be installed in one of three ways, as follows.
Garage door track installation (preferred):
1. Slip the curved arms over the rounded edge of each door track, with the
curved arms facing the door. Snap into place against the side of the
track. It should lie flush, with the lip hugging the back edge of the track,
as shown in Figure 1.
If your door track will not support the bracket securely, wall installation is
recommended.
Wall installation (Figures 2 and 3):
1. Place the bracket against the wall with curved arms facing the door. Be
sure there is enough clearance for the sensor beam to be unobstructed.
2. If additional depth is needed, an extension bracket (see Accessories) or
wood blocks can be used.
3. Use bracket mounting holes as a template to locate and drill (2) 3/16"
diameter pilot holes on the wall at each side of the door, no higher than
6" (15 cm) above the floor.
4. Attach brackets to wall with lag screws (not provided).
5. If using extension brackets or wood blocks, adjust right and left
assemblies to the same distance out from the mounting surface. Make
sure all door hardware obstructions are cleared.
Floor installation (Figure 4):
1. Use wood blocks or extension brackets (see Accessories) to elevate
sensor brackets so the lenses will be no higher than 6" (15 cm) above
the floor.
2. Carefully measure and place right and left assemblies at the same
distance out from the wall. Be sure all door hardware obstructions are
cleared.
3. Fasten to the floor with concrete anchors as shown.
