2 Test the Safety Reversal System
Withouta properlyinstalled safetyreversal system,
persons(particularlysmall children) could be
SERIOUSLY INJUREDor KILLED by a closing
garage door.
• Safety reversal system MUSTbe tested every
month.
• After ANY adjustmentsare made, the safety
reversal system MUSTbe tested.Door MUST
reverse on contact with 1-1/2" high (3.8 cm)
object (or 2x4 laid flat) on the floor.
2.1 With the door fullyopen, place a 1-1/2
inch (3.8 cm) board (or a 2x4 laid flat) on
the floor, centered under the garage
door.
2.2 Press the remote control push button to
close the door.The door MUSTreverse
when it makes contactwith the board.
If the door stops and doesnot reverse on
the obstruction, the travel needs to be
adjusted (refer to AdjustmentStep 1).
Repeat the test.When the door reverses
upon contactwith the 1-1/2 inch board,
remove the board and open/close the
door 3 or 4 timesto test the adjustment.
If the testcontinues to fail,call a trained
door systems technician.
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.
3.1 Open the door.Place the garage door
opener carton in the path of the door.
3.2 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 thatthe sensor is misaligned or
obstructed).
If the garage door opener closesthe door
when the safety reversing sensor is
obstructed (and the sensors are no more
than 6 inches [15 cm]above the floor),call
