Introduction
Be sure power is NOT connected to the garage door opener BEFORE installing the safety
reversing sensor.
To prevent SERIOUS INJURY or DEATH from closing garage door:
lCorrectly connect and align the safety reversing sensor. This required safety device MUST NOT
be disabled.
lInstall the safety reversing sensor so beam is NO HIGHER than 6" (15 cm) above garage floor.
IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS
The safety reversing sensors must be connected and aligned correctly before the garage door
opener will move in the down direction.
The sending sensor (with an amber LED) transmits an invisible lightbeam to the receiving sensor (with
a green LED). Ifan obstruction breaksthe lightbeam while the door is closing,the door will stop and
reverse to the full open position, and the garage door opener lights will flash 10 times.
NOTE: For energy efficiency the garage door opener will enter sleep mode when the door is fully
closed. The sleep mode shuts the garage door opener down until activated. The sleep mode is
sequenced with the garage door opener light bulb; as the light bulb turns off the sensor LEDs will turn
offand whenever the garage door opener lightsturn on the sensor LEDs will light. The garage door
opener will not go into the sleep mode until the garage door opener has completed 5 cycles upon
power up.
Wheninstalling the safety reversing sensors check the following:
lSensors are installed inside the garage,one on either side ofthe door.
lSensors are facing each other with the lenses aligned and the receiving sensor lens does not
receive direct sunlight.
lSensors are no more than 6 inches(15 cm) above the floor and the lightbeam is
unobstructed.
