Understanding Garage Door Sensors and Safety Features
November 28, 2024 4 min read
Modern garage doors include multiple safety features mandated by federal law since 1993. Understanding these features helps ensure your family's safety.
Photo-Eye Sensors Mounted 6 inches from the floor on either side of the door, these infrared sensors create an invisible beam. If anything breaks the beam while the door is closing, it automatically reverses.
*Maintenance Tips:* - Keep lenses clean (wipe monthly) - Ensure proper alignment (LED indicators) - Check for spider webs or debris - Protect from direct sunlight with shades
Auto-Reverse Mechanism If the door contacts an obstruction while closing, it should immediately reverse. Test monthly by placing a 2x4 flat on the floor—the door should reverse upon contact.
Manual Release The red emergency release cord disconnects the door from the opener, allowing manual operation during power outages. Know where yours is and test it periodically.
Rolling Code Technology Modern openers change the access code with each use, preventing code theft. If you have an older fixed-code opener, consider upgrading for security.
Smart Features New openers include: - Smartphone alerts when door opens - Auto-close timers - Guest access scheduling - Integration with home security
Never disable safety features. If sensors are malfunctioning, call for professional repair rather than bypassing them.
