Garage Door Openers – Information on safety reversal system

Posted on by Preferred Doors in Garage Door Openers, Houston Texas Leave a comment

Your garage door opener uses two safety reversal systems. The most obvious safety component is the safety eye system?, which provides four to six inches of coverage along the bottom area of the doorway. To test this system, perform the following steps:

1. Start with the door in the open position.
2. Press the remote control push button to raise the door.
3. Place a box or similar object in the path of the door (obstruction the safety sensor eyes).
4. Press the remote control push button to shut the door.

The door will not move more than 1 inch, and the opener lights will flash.

The door opener will not close from a remote if the indicator light in either one of the sensors is off (alerting you to the fact that the sensor is misaligned or obstructed).

Repeat this test each month.

There are a few things to keep in mind relating to the optical safety reversal system:
The optical safety system must be installed in order for the opener to close the door normally. The system is federally mandated, and there is absolutely no way to bypass this system. If there is a sensor problem, the opener can still be used to close the garage door. In order to do so, press and hold the hard-wired wall control button, or use the keyless entry pad outside of the garage, holding the ENTER button until the door reaches the floor. Releasing the wall control button or the ENTER button before the door reaches the floor will cause the opener to reverse the door. This selection is only available through the wall control or a keyless entry system, and is not an option when using the hand-held remote control. Never commit on the safety sensors to prevent the door from closing on an obstruction. Always assure that the path of the garage door is free of any obstructions before operating the opener mechanism.The second safety system built in to the opener is designed to reverse the garage door whenever resistance or force is encountered, provided that the opener mechanism is connected and adjusted properly, and the garage door is properly balanced and aligned. This reversal system should be tested each time an adjustment to the opener is made, and also once a month.

To test the safety reversal system:

1. With the door fully open, place a 1-1/2 inch board (or 2×4 laid flat) on the floor, centered under the garage door.
2. Operate the door in the down direction. The door must reverse upon striking an obstruction.

If the door stops on the obstruction, it is not traveling far enough in the down direction. Refer to your owner’s manual for instructions on increasing the down limit adjustment, along with farther information concerning the safety reversal test. A copy of your owner’s manual can be downloaded through most manufactor’s web sites by clicking here (hyperlink to owner’s manual search page) If the door continues to fail the safety reversal test, call for a trained door systems technician. Never rely on the safety reversal system to prevent the door from closing on an obstruction. Always ensure that the path of the garage door is clear of any obstructions before operating the opener mechanism.

WARNING: Without a correctly installed safety reversal system, persons (particularly small children) can be badly injured or death by a closing garage door.
WARNING: If the opener closes the door when the safety-reversing sensor is obstructed (and the sensors are no more than 6 inches above the floor), call for a trained garage door technician.
