Here's how it works:
* Two sensors: The photoelectric eye system uses two sensors, one mounted on the door and one on the track.
* Infrared beam: The sensors emit and receive an invisible infrared beam.
* Obstruction detection: If something breaks the beam (like a person, pet, or object), the sensors detect it and signal the door to reverse.
* Safety: This system prevents the door from closing on anything that might be in its path, ensuring the safety of people and objects.
Other modern safety features on garage door openers:
* Force-sensing technology: This feature detects an obstacle by sensing resistance or force on the door during closing. It will automatically reverse the door if an obstruction is detected.
* Manual release: A manual release lever allows you to disconnect the door from the opener, enabling you to open the door manually in case of power outage or malfunction.
* Door-to-door contact: This feature ensures that the door is properly closed and latched before the opener can operate.
Importance: These safety devices are crucial for preventing accidents and injuries. It's important to regularly inspect these features to ensure they are functioning properly.
