Install The Safety Reversing Sensor
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 orange 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 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 higher 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.
The mounting brackets are designed to clip onto the
track of sectional garage doors without additional
hardware.
• Be sure poweris not connectedto the garagedoor
openerBEFORE installing the safety reversingsensor.
• Toprevent SERIOUSINJURYor DEATH from a closing
garagedoor:
- Correctlyconnectand align the safety reversing
sensor.This required safetydevice MUSTNOTbe
disabled.
- Installthe safety reversing sensor so beam is NO
HIGHER than 6"above garagefloor.
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.
