Introduction Be sure power is NOT connected to the garage door opener BEFORE installing the safety reversing sensor. To prevent SERIOUS INJURY or DEATH from closing garage door:

Correctly connect and align the safety reversing sensor. This required safety device MUST NOT be disabled.

Install the safety reversing sensor so beam is NO HIGHER than 6" (15 cm) above garage floor. IMPORTANT: The safety reversing sensors MUST be connected and aligned correctly before the garage door opener will move in the down direction. The Protector System® includes two safety reversing sensors which use a light beam to prevent the garage door from closing. The sending sensor (amber LED) transmits the beam to the receiving sensor (green LED) when both are powered and aligned. The receiving sensor (green LED) has a label on the sensor to identify it as the receiving sensor before it is powered on. If an obstruction breaks the light beam while the door is closing, the door will stop, and reverse to the full open position. When installing the safety reversing sensors, check:

Sensors are installed INSIDE the garage.

Sensor lenses are facing each other. IMPORTANT: Do not allow direct sunlight to the receiving sensor (green LED).

Sensor beam is NO HIGHER than 6" (15 cm) above the floor and the light beam is unobstructed.

An improperly adjusted garage door and opener can exert deadly force when the door closes – which could lead to entrapment of children or adults and subsequent injury or death. Proper installation, operation, maintenance, and testing of the garage door and automatic opener are necessary to provide a safe, trouble-free system. Careless operation or allowing children to play with or use garage door opener controls are also dangerous situations that can lead to tragic results. A few simple precautions can protect your family and friends from potential harm. Please review the safety and maintenance tips in this guide carefully and keep it for reference. Check the operation of your garage door and opener to ensure they function in a safe and trouble-free manner. Be sure to read all Important Safety Information found in your garage door opener’s manual as it provides more details and safety considerations than can be supplied with this guide. Garage Door Openers are Not Toys Discuss garage door and opener safety with your children. Explain the danger of being trapped under the door. Stay away from a moving door. The wall-mounted push button should be out of reach of children, at least 5feet from the nearest standing surface and away from all moving parts. Mount and use the button where you can clearly see the closing garage door. Keep transmitters and remote controls out of reach of children. Do not let children play with or use transmitters or other remote control devices. Keep the door in sight until it completely closes when using the wall-mounted push button or transmitter.41 Routine Maintenance Can Prevent Tragedies Make monthly inspection and testing of your garage door and opener system a part of your regular routine. Review your owner’s manual for both the door and door opener. If you don’t have the owner’s manuals, contact the manufacturer(s) and request a copy for your specific model(s). Look for the opener model number on the back of the power unit. WARNING – SPRINGS ARE UNDER HIGH TENSION. ONLY QUALIFIED INDIVIDUALS SHOULD ADJUST THEM. Visually check the door and installation:

Starting with the door in the closed position, use the manual disconnect on the opener to disconnect the door.

Look for signs of wear or damage on hinges, rollers, springs, and door panels.

These parts may require periodic lubrication. Check the owner’s manual for suggested maintenance.

If any signs of damage are evident, contact a trained door systems technician for assistance.

Verify the photoeye height is no higher than 6" from the garage floor. Test the door for proper operation:

Open and close the door manually using handles or suitable gripping points.

The door should move freely and without difficulty.

The door should balance and stay partially open 3–4 feet above the floor.

If you detect any signs of improper operation, contact a trained door systems technician for assistance.

Test the opener safety features:

Reconnect the opener to the door using the manual disconnect and open the door.

Place a 2x4 board flat in the path of the door (1) and try to close it (2). The door should stop when it comes in contact with the 2x4 and then reverse direction.

Block the photoelectric sensor by waving an object in front of the sensor and attempt to close the door. The door should not close unless the wall-mounted push button is manually held during operation.

If the opener does not perform as described, contact a trained door systems technician for assistance.42 Repair Parts
