What does a photo eye do on a garage door?
Photo eyes situated on each side of the garage door opening transfer an electricity-formed infrared beam between them. Each photo-eye needs to “see” the other before the door can descend and fully shut. If the infrared beam is “tripped” or its “communications” are blocked, the sensors send a (warning) signal to the system. This causes the door to retract in response–protecting darting children, pets, and busy adults from the descending door. It also keeps objects below from damage if they are lying in the door’s direct path.
