Installation (continued)
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 fl ash 10 times.
When installing the sagety reversing senors, 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 fl oor 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 fl oor.
Be sure power is NOT connected
to the garage door opener
BEFORE installing the safety
reversing sensor.
To prevent SERIOUS INJURY or
DEATH from a 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
fl oor.
