Installation of Optional Safety Feature
THE SAFETY REVERSE SYSTEM TEST IS
IMPORTANT. GARAGE DOOR MUST
REVERSE ON CONTACT WITH A 25MM
OBSTACLE PLACED ON THE FLOOR.
FAILURE TO PROPERLY ADJUST OPENER MAY
RESULT IN SERIOUS PERSONAL INJURY FROM A
CLOSING GARAGE DOOR. REPEAT TEST ONCE A
MONTH AND ADJUST AS NEEDED.
REPEAT ADJUSTMENT STEP 3 AFTER:
• EACH ADJUSTMENT OF DOOR ARM LENGTH,
CLOSE FORCE OR DOWN LIMIT.
• ANY REPAIR OR ADJUSTMENT OF GARAGE
DOOR (INCLUDING SPRINGS AND HARDWARE)
• ANY REPAIR OR BUCKLING OF THE GARAGE
FLOOR.

THE PROTECTOR SYSTEM™ PROVIDES AN
ADDITIONAL MEASURE OF SAFETY AGAINST
A SMALL CHILD BEING CAUGHT UNDER A
GARAGE DOOR. It uses an invisible beam which,
when broken by an obstruction, causes a closing
door to open and prevents an open door from
closing. STRONGLY RECOMMENDED FOR
HOMEOWNERS WITH SMALL CHILDREN.

PROCEDURE: Place a 25mm obstacle on the floor
under the garage door. Operate door in DOWN
direction. The door MUST reverse on the
obstruction.
If the door STOPS on the obstruction, it is not
traveling far enough in the DOWN direction.
Increase the DOWN limit by turning DOWN limit
adjustment screw counterclockwise 1/4 turn.
REPEAT TEST.
NOTE: Make sure limit adjustments do not force
the door arm beyond a straight up and down
position. See the illustration on page 18.
When the door reverses on the 25mm obstacle,
remove the obstruction and run the opener through
3 or 4 complete travel cycles to test the adjustment.
Door MUST NOT reverse in closed position. Repeat
Adjustment Steps 1, 2 and 3 if necessary.
After opener has been installed and adjusted, THE
PROTECTOR SYSTEM™ accessory can be
installed.
