Local context
Automatic residential garage door openers sold in the United States have been subject to federal entrapment protection rules for decades. The Consumer Product Safety Commission's notice on the final rules describes an external entrapment protection device, such as an electric eye that detects an object obstructing the door without touching it, or a door edge sensor, and applies additional entrapment protection requirements to openers manufactured on or after 1 January 1993. If an opener is being diagnosed or replaced, ask how the safety reversal and the sensors will be tested afterwards. This is background, not an assessment of your equipment.
