The safety reversing sensor must be connected

IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSOR
W
hen properly connected and aligned, the sensor
will detect an obstacle in the path of its electronic
beam. The sending eye transmits an invisible light
beam to the receiving eye. 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" 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.
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. 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.
N
o part of the garage door (or door tracks, springs,
hinges, rollers or other hardware) may interrupt the
beam while the door is closing.
Be sure power is not connected to the garage door
opener BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from a closing
garage door:
• Correctly connect and align the safety reversing sensor.
This required safety device MUST NOT be disabled.
• Install the safety reversing sensor so beam is NO
HIGHER than 6" above garage floor.
