Test the Protector System

Without a properly installed safety
reversing sensor, persons (particularly
small children) could be SERIOUSLY
INJURED or KILLED by a closing
garage door.
2.1
With the door fully open, place
a 1-1/2 inch (3.8 cm) board
(or a 2x4 laid fl at) on the fl oor,
centered under the garage door.
®
3.1
Open the door. Place the garage
door opener carton in the path
of the door.
2.2
Press the remote control push
button to close the door. The door
MUST reverse when it makes
contact with the board.

opener lights will fl ash 10 times.

11
If the door stops and does not reverse on
the obstruction, increase the down travel
(refer to Adjustment Step 1).
Repeat the test. When the door reverses
upon contact with the 1-1/2 inch board,
remove the board and open/close the door 3
or 4 times to test the adjustment.
If the test continues to fail, call a trained
door systems technician.
The garage door opener will not close
from a remote control if the LED in either
safety reversing sensor is off (alerting you
to the fact that the sensor is misaligned or
obstructed).
If the garage door opener closes the
door when the safety reversing sensor is
obstructed (and the sensors are no more
than 6 inches [15 cm] above the fl oor), call
for a trained door systems technician.
