INSTALLATION STEP 10

Install The Protector System

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 green 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" (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.

Protection Area
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.
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.
