Be sure power is not connected to the garage door opener

BEFORE installing the safety reversing sensor.

To prevent SERIOUS INJURY or DEATH from a 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.

Safety Sensor Brackets

Model 41a6569

Be sure power to the opener is disconnected.

The sending eye transmits an invisible light beam to the receiving

eye. The units can be installed on either side of the garage door as

long as the sun never shines directly into the receiving eye lens.

Look at the label on the connector end of each case to identify the

sensors.

The brackets must be connected and fastened so that the sending

and receiving eyes face each other as shown in Figure 1.

If an obstruction breaks the light beam while the garage door is

closing, the door will stop and reverse to full open position, and

the opener lights will fl ash for 5 seconds.

The brackets must be securely fastened to a solid surface such as

the studs on either side of the door, or add a piece of wood at each

location if installing in masonry construction.

The invisible light beam path must be unobstructed. No part of the

garage door (or door tracks, springs, hinges, rollers or other

hardware) can interrupt the beam while the door is closing. If it

does, use a piece of wood to build out each sensor mounting

location to the minimum depth required for light beam clearance.
