Since 1993, automatic residential garage doors have been required to have security sensors that prevent the door from closing on a person or object. These sensors act as a key safety feature for automatic garage doors, and are located opposite each other with the garage door in between them. Federal Law UL 325 requires that all garage doors include security mechanisms, such as garage door sensors, which are the most commonly used. Your garage must have an approved security device, such as sensors, on the garage door.
Garage door sensors, or photoelectric eye sensors, are devices installed on your garage doors that help prevent anything from being injured when the garage collapses. They work by transforming electricity into an infrared beam of light to create an invisible cable trap. One sensor is called a sending unit and the other is called a receiving unit. As long as nothing prevents the laser from breaking the connection, the garage door will close without problems.
However, if something obstructs the connection, such as a child running under the door, the garage will stop and move forward again to prevent an accident from occurring. Both sensors usually have indicator lights. One has a green light to indicate that the units are turned on. The other has a red light that confirms that there are no obstructions between the sensors and that they can be “seen”.
If one or both of the sensors show flashing lights, it means they are not aligned. Simply use a screwdriver to tighten the screws on the bracket or fold the bracket back into place. To clean it, simply use a soft cloth and a mild cleanser that doesn't leave scratches. In some cases, sensors may have tight cables that reduce their voltage, causing inconsistent operation.
To fix the problem, you will have to completely replace the entire system or contact a professional. You may want to turn off your electric opener until repairs are done to avoid injury or property damage. Make sure that the safety sensors are installed correctly and that the wiring is not damaged and properly connected. Under no circumstances should you deactivate or remove the safety sensors, unless you are trying to repair or replace them. Modern garage door systems are equipped with two security sensors which “communicate with each other” and send an infrared beam in a straight line from one end of the door to the other.
As we mentioned earlier, every automated garage door must include a security feature. You may not think much about them, but those sensors on the underside of your garage door influence how your garage door opener works. Sensors for opening garage doors are also called photoelectric security sensors. They ensure that your garage door stops closing or opening when you recognize that there is something in your way.Garage door sensors work by firing an infrared beam of light through the garage entrance to the sensor on the other side. As long as the beam is not interrupted, the door will open or close normally.
The infrared ray from the garage door opener sensors cannot be seen by human eyes. That's why it's important to understand their function and make sure they work properly. In this blog, we'll explore what garage door sensors are, how they work, and what you can do if they don't work properly. Garage doors can weigh between 400 and 500 pounds, making them as dangerous as rocks if they fell completely without a flag to stop them. That's why it's important to make sure your safety sensors are working properly at all times in order to keep you and your family safe.
