The Safety Reversing System

Information you'll need before you begin the installation of the safety reversing sensor.

The safety reversing sensor must be connected and aligned correctly before the garage door opener will move in the down direction° This is a required safety device and cannot be disabled.

Installation procedures are the same for sectional and one-piece doors.

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 flash for 5 seconds.

Without a properly working safety reversing sensor, persons (particularly children) could

be injured or killed by a closing garage door. Read and follow all Instructions.

To protect small children, install the safety reversing sensor so that the beam will be no higher than 4"-6" above the garage floor.

Disconnect power to the garage door opener before installing the safety reversing sensor.

..................................i

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, spdngs, 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.
