# Crush Prevention Systems: Protecting Your Family
Every year, approximately 30,000 people are injured by garage doors in the United States. While most injuries are minor, some are severe or even fatal.particularly among children. Modern crush prevention systems are designed to prevent these tragedies. Understanding how these systems work and ensuring they're properly maintained is essential for every homeowner.
The Importance of Garage Door Safety
Your garage door is likely the largest, heaviest moving object in your home. A typical residential garage door weighs between 150 and 400 pounds. Combined with the powerful springs and motor required to move it, an improperly functioning garage door poses serious risks:
- Crush injuries: The most serious risk, particularly to children and pets - Pinch injuries: Fingers or hands caught between panels - Falling door injuries: From broken springs or cables - Impact injuries: From doors reversing unexpectedly
Federal regulations now require all garage door openers to include specific safety features, but understanding and maintaining these systems is your responsibility.
Understanding Photo-Eye Sensors
Photo-eye sensors are the primary crush prevention system on modern garage doors. Here's how they work:
How Photo-Eyes Function
Two small sensors are mounted on either side of the garage door opening, typically 6 inches from the floor. One sensor transmits an invisible infrared beam to the other. When anything breaks this beam while the door is closing, the opener immediately reverses the door.
Key Features
- Instant Response: The system reacts immediately when the beam is broken - No Contact Required: The door reverses before contacting the obstruction - Always Active: Sensors work every time the door closes - LED Indicators: Lights show when sensors are aligned and functioning
Testing Your Photo-Eyes
Test your photo-eye sensors monthly:
1. Start closing the garage door 2. Wave a broom handle or similar object through the beam 3. The door should immediately stop and reverse 4. If it doesn't, do not use the door until repairs are made
Troubleshooting Photo-Eyes
Common issues and solutions:
Sensors won't align: Check for physical damage, clean lenses, adjust alignment Intermittent operation: Look for sunlight interference, vibration, or dirty lenses LEDs blinking: Usually indicates alignment issues or wiring problems Complete failure: May need sensor replacement
Auto-Reverse Mechanism
The auto-reverse mechanism is a secondary safety feature that activates when the door contacts an obstruction.
How Auto-Reverse Works
Modern garage door openers include force sensors that detect when the door meets unexpected resistance. When the closing force exceeds a preset level, the opener reverses the door direction.
Testing Auto-Reverse
Test the auto-reverse monthly:
1. Place a 2x4 flat on the ground in the door's path 2. Close the door 3. When the door contacts the board, it should reverse within 2 seconds 4. Adjust the force settings if necessary
Adjusting Sensitivity
If the auto-reverse is too sensitive or not sensitive enough, the force settings can be adjusted. However, we recommend having a professional make these adjustments to ensure optimal safety.
Additional Safety Features
Manual Release
Every garage door opener includes a manual release that allows you to operate the door if the power goes out or the opener fails:
- Usually a red cord hanging from the opener track, Pulling the cord disconnects the door from the opener, The door can then be operated manually, Reconnect before using the opener again
Rolling Code Technology
Modern openers use rolling codes that change with each use:
- Prevents "code grabbing" by thieves, Each time you press your remote, a new code is used, Old codes cannot be reused to open the door
Timer-to-Close
Some openers offer a timer-to-close feature:
- Automatically closes the door after a preset time, Useful if you forget to close the door, Includes warning lights and beeps before closing, Can be disabled when needed
Battery Backup
Battery backup systems provide:
- Operation during power outages, Peace of mind during storms, Ability to close and secure your garage
Child Safety Best Practices
Children are particularly vulnerable to garage door injuries. Follow these guidelines:
Education, Teach children that garage doors are not toys, Explain the dangers of playing near or under the door, Demonstrate the remote controls and keypads, Never let children operate the door unsupervised
Physical Safeguards, Mount wall controls at least 5 feet high, Keep remotes out of children's reach, Ensure photo-eyes are clean and aligned, Test safety features monthly
Supervision, Watch children in the garage, Ensure the door is fully closed or open before allowing play, Never allow children to race the closing door
When to Upgrade Your Safety Systems
Consider upgrading if:
- Your opener was manufactured before 1993 (lacks photo-eyes) - Safety features are unreliable or frequently fail, The opener is more than 15 years old, You're experiencing frequent false reversals, The door makes unusual sounds
