Install the Protector System

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:
•
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 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. The receiving sensor (green LED) has a label on the sensor to identify it as the
receiving sensor before it is powered on. If an obstruction breaks the light beam while the door is closing, the
door will stop, and reverse to the full open position.
When installing the safety reversing sensors, check:
•
Sensors are installed INSIDE the garage.
•
Sensor lenses are facing each other. IMPORTANT: Do not allow direct sunlight to the receiving sensor
(green LED).
•
Sensor beam is NO HIGHER than 6" (15 cm) above the floor and the light beam is unobstructed.
•
The receiving sensor has a warning sticker on the back.
