(Safety reversing sensors)
The safety reversing sensor must be connected and
aligned correctly before the garage door opener will
move in the down direction.
IMPORTANT INFORMATION ABOUT THE SAFETY
REVERSING SENSOR
When properly connected and aligned, the sensor will
detect an obstacle in the path of its electronic beam. The
sending eye (with an amber indicator light) transmits an
invisible light beam to the receiving eye (with a green
indicator light). If an obstruction breaks the light beam
while the door is closing, the door will stop and reverse
to full open position, and the opener lights will flash
10 times.
The units must be installed inside the garage so that the
sending and receiving eyes face each other across the
door, no more than 6" (15 cm) above the floor. Either can
be installed on the left or right of the door as long as the
sun never shines directly into the receiving eye lens.
The mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware°

If it is necessary to mount the units on the wall, the
brackets must be securely fastened to a solid surface
such as the wall framing. Extension brackets (see
accessories) are available if needed. If installing in
masonry construction, add a piece of wood at each
location to avoid drilling extra holes in masonry if
repositioning is necessary.
The invisible light beam path must be unobstructed. No
part of the garage door (or door tracks, springs, hinges,
rollers or other hardware) may interrupt the beam while
the door is closing.
