Test the Safety Reversal System
Test
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 push button to close the door. The door
MUST reverse when it makes contact with the board.
If the door stops but does not reverse:
1. Review the installation instructions provided to insure all steps were
followed.
2. Repeat Program the Travel (see Adjustment).
3. Repeat the Safety Reversal test.
If the test continues to fail, call a trained door systems technician.
Important safety check:
Test the Safety Reverse System after:
• Any repair to or adjustment of the garage door (including springs and
hardware).
• Any repair to or buckling of the garage floor.
• Any repair to or adjustment of the opener.
Test the Protector System
®
1. Press the remote control push button to open the door.
2. Open the door. Place an obstruction in the path of the door.
3. Press the remote control push button to close the door. The door will
not move more than an inch (2.5 cm), and the garage door opener
lights will flash 10 times.
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 floor), call for a trained door systems technician.
Synchronize the Door Control
To synchronize the door control to the garage door opener, press the push
bar until the garage door opener activates (it may take up to 3 presses).
Test the door control by pressing the push bar. Each press of the push bar
will activate the garage door opener.
Without a properly installed safety reversal system, persons
(particularly small children) could be SERIOUSLY INJURED or KILLED
by a closing garage door.
• Safety reversal system MUST be tested every month.
• 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.
Without a properly installed safety reversing sensor, persons
(particularly small children) could be SERIOUSLY INJURED or KILLED
by a closing garage door.
