# Crush Prevention Systems: Protecting Your Family
Garage doors are the largest moving objects in most homes, weighing anywhere from 150 to over 400 pounds. Without proper safety systems, this weight poses a serious crushing hazard, particularly for children and pets. Understanding these systems helps you protect your family and ensure your door meets current safety standards.
The History of Garage Door Safety
Before 1993, garage door injuries and fatalities were tragically common. The U.S. Consumer Product Safety Commission mandated specific safety features for all residential garage door openers manufactured after January 1, 1993.
These regulations require two independent safety systems: a mechanical auto-reverse feature and photoelectric sensors. Openers made before this date lack these crucial safety features and should be replaced with a modern opener.
Understanding Auto-Reverse Mechanisms
The mechanical auto-reverse feature detects resistance during the closing cycle. When the door contacts an object, the motor immediately reverses direction. Testing your auto-reverse is simple and should be done monthly.
The sensitivity settings balance safety against false reversals. Professional calibration through our maintenance service ensures optimal settings.
Photoelectric Safety Sensors
Photoelectric sensors are mounted near the floor on either side of the garage door opening. One sensor emits an invisible infrared beam while the other receives it. When this beam is interrupted, the door immediately stops and reverses.
Common sensor issues include misalignment, dirty lenses, and sunlight interference. Regular checks during maintenance visits ensure reliable function.
Additional Safety Features
Timer-to-close functionality automatically closes the door after a set period.
Motion detection technology can sense movement in the door's path even before contact.
Battery backup systems ensure safety features remain operational during power outages.
Smartphone connectivity allows you to monitor door status remotely. Learn more about smart features in our opener troubleshooting guide.
Testing and Maintenance
Regular testing of safety systems is essential. The CPSC recommends monthly testing of both the auto-reverse and photoelectric sensors.
Testing auto-reverse: Place a 2x4 flat under the door. The door should reverse upon touching the board.
Testing sensors: While the door is closing, wave an object through the sensor beam. The door should immediately reverse.
When to Upgrade Your Safety Systems
Consider upgrading if your opener was manufactured before 1993, safety sensors frequently malfunction, or you want enhanced features like battery backup. A new garage door installation includes the latest safety technology.
Teaching Children About Garage Door Safety
Even with excellent safety systems, education remains important. Teach children never to play around or under a moving garage door, and keep remotes out of reach of young children.
