Install the Safety Reversing Sensor

(Receiving and Sending Eyes)
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 from 4 – 6" above
the floor.
They may be installed in one of three ways, as follows.
Garage door track installation (preferred):
• Slip the curved arms over the rounded edge of the door
track. 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:
• 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.
• If additional depth is needed, an extension bracket (see
Accessories) or wood blocks can be used.
• 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, from 4–6" above the floor.
• Attach brackets to wall with lag screws (not provided).
• 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:
• Use wood blocks or extension brackets (see
Accessories) to elevate sensor brackets so the lenses
will be 4-6" above the floor.
• Carefully measure and place right and left assemblies at
the same distance out from the wall. Be sure all door
hardware obstructions are cleared.
• Fasten to the floor with concrete anchors as shown.
