INSTALLATION STEP 10
Install the Safety Infrared
Reversing Sensors (Optional)
It is recommended that safety infrared reversing
sensors be connected and aligned correctly to
the garage door opener.
The force, as measured on the closing edge of
the door, should not exceed 400N (40kg). If the
closing force is adjusted to more than 400N, this
safety system must be installed.
IMPORTANT INFORMATION ABOUT
THE SAFETY REVERSING SENSORS
When properly connected and aligned, the safety
infrared reversing sensors 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 light 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, between 100-150mm 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 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.
