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: The safety reversing sensors MUST be connected and aligned correctly before the garage
door opener will move in the down direction.
The Protector System® includes two safety reversing sensors which use a light beam to prevent the garage
door from closing. The sending sensor (amber LED) transmits the beam to the receiving sensor (green LED)
when both are powered and aligned. 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.
When installing the safety reversing sensors, check:
l Sensors are installed INSIDE the garage.
l Sensor lenses are facing each other. IMPORTANT: Do not allow direct sunlight to the receiving sensor
(green LED).
l Sensor beam is NO HIGHER than 6" (15 cm) above the floor and the light beam is unobstructed.

The safety reversing sensors are designed to clip onto the door track with the provided sensor brackets. If
the door track will not support the sensor bracket a wall installation is recommended. The sensor beam should
be NO HIGHER than 6" (15 cm) above the floor.
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 hex screw through the sensor.
3. Attach the sensor to the bracket with the wing nut. Make sure the lens is not obstructed by the
bracket.
Repeat the steps with the other sensor on the opposite door track. Both lenses must face each other.
6" (15 cm) max.
