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..

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
(Figure 1)
If your door track will not support the bracket securely,
wall instaIlation is recommended.

- 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.

side of the door, no higher than 6" (15 cm) above the
