East Wenatchee Home Inspections




Garage door photo eyes or sensors (Safe-T-Beam) are an important safety device and they need to work properly. The requirement for these safety devices was to reduce the number of deaths to children who become entrapped under garage doors with automatic openers. So in 1993 the U.S. Consumer Product Safety Commission (CPSC) required that all garage doors to be equipped with an external entrapment protection device. These devices are typically an "electric eye/photo eye" which sees an object obstructing the door without actual contact with the object but it could be a door edge sensor.

So now you have this “Photo Eye”  and then something goes wrong and the door will not go down. These safety reversing sensors (photo eyes) must be properly aligned and connected before the garage door opener will move in the down direction.  Typically issues with the safety sensor is either poor alignment or wiring issues such as a poor connection, incorrectly connected wires, or a short in the wire such as from a staple.


On several home inspections I have found photo eyes in some strange places.
 
 
No issues here...right?
