Operation
The Protector System®(Safety Reversing Sensors)
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.
The safety reversing sensors must be connected and
aligned correctly before the garage door opener will
move in the down direction.
When the light beam is obstructed or misaligned while the
door is closing, the door will reverse and the garage door
opener lights will flash ten times. If the door is already
open, it will not close.
The sensors can be aligned by loosening the wing nuts,
aligning the sensors, and tightening the wing nuts. Check
to make sure the LEDs in both sensors are glowing
steadily. The LEDs in both sensors will glow steadily if they
are aligned and wired correctly.
