IMPORTANT SAFETY INFORMATION
IMPORTANT SAFETY INSTRUCTIONS
Garage doors are large and heavy objects that move with the help of springs under high tension and electric
motors. Since moving objects, springs under tension, and electric motors can cause injuries, your safety and
the safety of others depends on you reading the information in this installation manual. If you have questions or
do not understand the information presented, call Linear PRO Access Technical Support at 1-800-543-1236.
TO REDUCE THE RISK OF SEVERE INJURY OR DEATH TO PERSONS, REVIEW THESE INSTALLATION
SAFETY STEPS BEFORE PROCEEDING
1 READ AND FOLLOW ALL INSTALLATION INSTRUCTIONS.
2 Never let children operate or play with door controls. Keep the remote control away from children.
3 Always keep the moving door in sight and away from people and objects until it is completely closed. NO
ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4 NEVER GO UNDER A STOPPED, PARTIALLY OPEN DOOR.
5 Test the door monthly. The garage door MUST reverse on contact with a 1-1/2 inch high object (ir 2 x 4
board laid at) on the oor. After adjusting either the force or the limit of travel, retest the door opener.
Failure to adjust the opener properly increases the risk of severe injury or death.
6 For products having an emergency release, when possible, use the emergency release only when door is
closed. Use caution when using this release with the door open. Weak or broken springs are capable of
increasing the rate of door closure and increasing the risk of severe injury or death.
7 KEEP GARAGE DOORS PROPERLY BALANCED. See user’s manual. An improperly balanced door increases
the risk of severe injury or death. Have a qualied service person make repairs to cables, spring assemblies,
and other hardware.
8 For operator systems equipped with an unattended operation feature, the following statement shall be
included: “This operator system is equipped with and unattended operation feature. The door could move
unexpectedly. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR”.
9 SAVE THESE INSTRUCTIONS.
WARNING
Important Safety Information will follow
the words CAUTION and WARNING
which are used to emphasize potentially
hazardous situations.
WARNING
This type of warning note is used
to indicate possible mechanical
hazards that may cause serious
injuries or death.
CAUTION
This type of warning note is
used to indicate the possibility
of damage to the garage door or
garage door opener.
Children operating or playing with a garage door opener can injure themselves or others.
The garage door could cause serious injury or death. Do not allow children to operate the
remote control(s) or the wall station. Install the wall station out of reach of children and
away from all moving parts of the door. The door must be clearly visible from the wall
station. A moving garage door could injure someone under it. Only activate the door when
it is properly adjusted, when it can be seen clearly, and when there are no obstructions to
the door travel.

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 ash 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 ash 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 icker. Rotate
the sender back towards a horizontal position with the oor
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 ash and beep.
4 The garage door opener will not close if the beams are misaligned or
obstructed.
IMPORTANT: If the garage door closes when the safety beam is
obstructed, call a professional garage door technician.
