The photo-eye sensors are located about 6 inches above the floor level, and one is on the other side of the door.
It releases an invisible beam that connects the two of them, and if anything interferes with it, the sensor signals it to the system, so that the door does not close.
In 1993, a law was passed stating that all garage door systems must have an infrared light beam safety for a reverse mechanism to prevent garage door trapping.
This law requires having a safety device passed because the main reason is to avoid any injury to the garage door user to pets and also to protect the equipment of the homeowner’s form damage.
According to some reports, more than 73 children aged 2 to 14 years old, were trapped and died due to automatic garage doors since March 1982.
The response to this was the mandate to have a photo-eye sensor on each garage door.
This law not only aims to protect people from accidents but also to reduce the costs of damage to equipment due to the garage door.
Without this sensor, anyone can press the remote intentionally or accidentally to close the door.
It will continue to close even if it is blocked. Someone may be injured, or the vehicle may break down.
But, having a photo-eye sensor, when it detects that something is blocking the garage door, it will stop closing.
Imagine if having a photo-eye sensor is not implemented, there is an excellent possibility that there will be more cases of vehicle damage and people’s death.
Due to this, having a photo-eye sensor has prevented such incidents.
Now that you already know the purpose and importance of the photo-eye sensor, here are some tips about how you will protect your sensor from damage.
Making sure your garage door photo-eye is doing their intended function:
When your photo-eye is dirty, it may not work correctly. It is essential to test your sensor once a year to see if it is still functioning correctly.
Open the garage door, and as it opens, close it through the transmitter.
Take something that could break the sensor beam. After doing all this, the garage door should go back up.
If your garage door does not close, check the two photo-eye positions, see if they are equal, and focus directly on each other.
When your photo-eye sensor works, it will not let the garage door close if the sensor is uneven.
Signs that your sensors are not working:
If you have noticed that your garage door is not working correctly, fix them immediately.
- Flickering of the sensor’s light is one of the signs that something is wrong with it.
- The garage door does not go back when instructed.
- The garage door goes down and then back up.
Clean your photo-eye; it may be dirty.
- When the garage door returns, the photo-eye is more likely to work.
- Check the photo-eye; it may be dirty and needs cleaning. Clean it with a lens cleaner designed for glasses.
- When you have finished cleaning and troubleshooting the photo-eye, test it again.
- If this still does not work, I advise you to call a professional technician.
