A garage door opener is a wonderful luxury that can make lives easier. It allows homeowners to stay in their cars during inclement weather. Because the door is quite big and heavy, the opener also makes it easier to open the door. Professional installation can make sure the door and opener work in conjunction with each other safely and efficiently. A professional opener installation in Marietta can also ensure the extra safety features are installed correctly.
Every garage door opener is connected to a pair of sensors. These sensors are mounted on each side of the door at the bottom of the tracks. One sensor sends an infrared beam to the other sensor. If this beam is interrupted, the sensors will send a signal to the opener to stop lowering the door and pull it back up. This prevents injuries to pets or children that try to run under the door while it is closing. It can also prevent damage to the door or vehicle by detecting an obstruction in the path of the door. For example, if the car is not fully in the garage and is interrupting the beam, the door will not close. A good way to test the beams is to roll a ball out of the garage while the door is closing. Once the ball breaks the beam, the opener should change course and begin to open the door.
The auto-reverse feature should also work without the sensors. The opener is designed to detect an obstruction preventing the door from closing. Once the door comes in contact with such obstructions, the opener will reverse the course of the door and move it back to an open position. Sticking with the car not fully in the garage example, the back end of the car maybe higher than the sensor beam but not fully in the garage. It is not interrupting the beam so the opener will start to close the door. The door will lower until it reaches the car and then reverse course when the opener feels resistance. This can be tested with a board or pot that is placed directly in the path of the door but not interfering with the sensor beams. If the auto reverse is working correctly, the opener will pull the door back open once it reaches the obstruction.
In order to open the door, the opener uses a carriage that travels along a track. This carriage is attached to the door with a handle that can be disengaged with a manual release. The manual release usually has a long rope with a red handle attached to it. By pulling the handle downwards, the door is disconnected from the carriage and can be opened and closed manually. Most of the time, the manual release is used during a power outage so the door can be opened and closed. But, it is also designed to open and close the door if the other safety features fail and someone or something is trapped under the door. The manual release should be pulled on a regular basis to test it works properly.
One feature that many people may not be aware of is the lockout function on the opener. This switch will lock the door and prevent the opener from operating. One way thieves can access a home is by driving around a neighborhood pushing the button on a remote opener. If the door opener is locked, they cannot gain access to the garage.
The garage door is the largest moving part of any house. All of these safety features will work together to ensure it is safe to operate. Having a professional opener installation in Marietta will ensure these features are connected properly and the opener works like it is designed to.
