The safety reversing sensor must be connected and aligned
correctly before the door operator will move in the down
direction. This is a required safety device and cannot be
disabled.
IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING
SENSOR
When properly connected and aligned, the safety reversing sensor
will detect an obstacle in the path of its electronic beam. The
sending eye (with an amber 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.
The units must be installed inside the building 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. 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 door (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 door operator BEFORE
installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from a closing 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 floor.
