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 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" (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.
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. No 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" (15 cm) above garage floor.
