IMPORTANTINFORMATION ABOUTTHE SAFETYREVERSING
SENSOR
When properly connected and aligned, the sensor will detect an
obstacle in the path of its electronic beam. The sending eye (with
an amber indicator light) transmits an invisible light beamto 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 reverseto 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) abovethe 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 designedto clip onto the track of
sectional garage doors without additional hardware.
Be sure power is NOTconnected to the garage door opener
BEFORE installing the safety reversing sensor.
To prevent SERIOUSINJURYor DEATHfrom a closing garage
door:
• Correctly connect and align the safety reversing sensor. This
required safety device MUST NOTbe disabled.
• Install the safety reversing sensor so beam is NO HIGHER
than 6" (15 cm) abovegarage floor.
If it is necessaryto mount the units on the wall, the brackets must
be securely fastened to a solid surface such as the wall framing.
Extension brackets (seeAccessories) are availableif 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.
