Installation
STEP 13 Install the Protector System
®
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:
l Correctly connect and align the safety reversing sensor. This required safety device MUST NOT be
disabled.
l Install 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 light beam to the receiving sensor (with a green
LED). If an obstruction breaks the light beam 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 off and whenever the garage door opener lights turn 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.
When installing the safety reversing sensors check the following:
l Sensors are installed inside the garage, one on either side of the door.
l Sensors are facing each other with the lenses aligned and the receiving sensor lens does not receive direct
sunlight.
l Sensors are no more than 6 inches (15 cm) above the floor and the light beam is unobstructed.

HARDWARE
The safety reversing sensors can be attached to the door track, the wall, or the floor. The sensors should be no more
than 6 inches (15 cm) above the floor. If the door track will not support the sensor bracket a wall installation is
recommended. Choose one of the following installations.
OPTION A - DOOR TRACK INSTALLATION
1. Slide the curved arms of the sensor bracket around the edge of the door track. Snap into place so that the
sensor bracket is flush against the track.
2. Slide the carriage bolt into the slot on each sensor.
3. Insert the bolt through the hole in the sensor bracket and attach with the wing nut. The lenses on both
sensors should point toward each other. Make sure the lens is not obstructed by the sensor bracket.
