IMPORTANTINFORMATIONABOUTTHESAFETYREVERSINGSENSOR
When properly connected andaligned, 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
breaksthe 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 garageso that the sending
and receivingeyesface 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.
