STEP 2 Test the Safety Reversal System
Without a properly installed safety reversal system, persons (particularly small children) could be
SERIOUSLY INJURED or KILLED by a closing garage door.
l
Safety reversal system MUST be tested every month.
l
After ANY adjustments are made, the safety reversal system MUST be tested. Door MUST reverse on
contact with 1-1/2" (3.8 cm) high object (or 2x4 laid flat) on the floor.
1.
With the door fully open, place a 1-1/2 inch (3.8 cm) board (or a 2x4 laid flat) on the floor, centered
under the garage door.
2.
Press the remote control or wall-mounted door control to close the door. The door should stop and
reverse when it makes contact with the board. The door returns to the previous open position.
Opener beeps and lights flash 5 times.
3.
If the door reverses, remove the board. The test is complete.
If the door stops but does not reverse:
1.
Review the installation instructions provided to insure all steps were followed;
2.
Refer to Adjustment Step 1 and and set the down limit closer to the garage floor.
NOTE:
On a
sectional door, make sure adjustments do not force the door arm beyond a straight up and down
position.
3.
Repeat the Safety Reversal test.
If the test continues to fail, call a trained door systems technician.

STEP 3 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.
1.
Open the door. Place the garage door opener carton in the path of the door.
2.
Press the remote control push button to close the door. The door will not move more than 1"
(2.5 cm), the garage door opener lights will flash 10 times, the green LED on the receiving sensor
will blink.
The garage door opener will not close from a remote control if the sensor light beam 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" [15 cm] above the floor), call for a trained door systems technician.
