The safety reversing sensor must be connected and aligned correctly before the garage door
opener will move in the down direction. This is a required safety device and cannot be disabled.
IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSOR
When properly connected and aligned, the safety reversing 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 fl ash 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 inches (15 cm) above the fl oor. 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 (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" (15 cm)
above garage fl oor.
