TESTING THE SAFETY BEAM
The safety beam has two components, a sender and a receiver. The sender
produces a narrow infrared beam that travels across the bottom of the
door opening to the infrared receiver. If an object blocks the infrared beam
while the door is closing, the door will stop, then reverse and fully open
(the opener’s light will flash three times).
As a safety feature, the opener will ignore signals from all remote controls
if the door is open and the infrared safety beam is blocked or out of
alignment. In this case, the door can be forced closed by pressing and holding the wall station’s up/down
arrow pushbutton (be sure the door area is in clear view).
Safety Beam Test
1 Check that the opener has power. The green lights on the
sender and receiver should be lit.
2 If the receiver’s green light is on, but the red light is off, the
receiver has power but is not detecting the infrared beam
from the sender. The red light might flash when the beam
is partially detected. This can be caused by mis-alignment
or something blocking the beam. Adjust the safety beam
sender and receiver while watching the receiver’s red light
(stay out of the beam while aligning it). When the red light
stays on, rotate the sender towards the ceiling and stop
when the red light on the receiver begins to flicker. Rotate
the sender back towards a horizontal position with the floor
and stop as soon as the red light on the receiver lights solid.
The beam is now properly aligned.
NOTE:
If the receiver’s red light remains off, check for: 1) Dirt on the receiver’s lens, 2) Sunlight shining into
the receiver’s lens, 3) A short in the safety beam wiring (from staples or at the opener terminals).
3 • Press the remote control button to open the garage door.
• Place a box in the path of the safety beams.
• Press the remote control button to close the door. The door will not
move and the opener‘s lights will flash and beep.
4 The garage door opener will not close if the beams are misaligned or
obstructed.
NOTE:
If the door remains idle for 5 minutes, the beam light will turn
off to save power. The beam power turns on for 5 minutes when door
moves down to the fully closed position. The beam power can be restored for 5 minutes by pressing the
light button.
IMPORTANT:
If the garage door closes when the safety beam is obstructed, call a professional garage door
technician.
• Photo beams MUST be installed on the garage door to prevent serious injury or death.
• This required safety reversing sensor MUST NOT be disabled at any time.
• Photo beams should be installed no higher than 6” above the floor.
