<p>Garage doors are the largest moving objects in most homes, weighing 150 to 400 pounds or more. Without proper safety systems, they pose serious crush hazards to children, pets, and adults. Understanding modern safety technology helps you protect your family and ensure your door meets current safety standards.</p>
<h2>The Importance of Safety Systems</h2> <p>Before 1993, garage door injuries were disturbingly common. Federal regulations now require all automatic garage doors to have entrapment protection. However, older systems may not meet current standards, and all systems require regular testing to ensure proper function. A malfunctioning safety system provides false security.</p>
<h2>Photo-Eye Sensors</h2> <p>These sensors mount six inches above the ground on either side of the door opening. An invisible infrared beam crosses the opening; if anything breaks the beam while the door closes, it immediately reverses. Test monthly by waving an object through the beam during closing. Misaligned or dirty sensors are common causes of malfunction.</p>
<h2>Auto-Reverse Mechanism</h2> <p>This mechanical system detects resistance when the door contacts an object and reverses direction. Required by law since 1991, it serves as a backup to photo-eye sensors. Test by placing a 2x4 flat on the ground where the door closes. The door should reverse upon contact. If it doesn't, the sensitivity needs adjustment or the mechanism needs repair.</p>
<h2>Pinch-Resistant Panels</h2> <p>Traditional sectional doors create pinch points between panels as the door operates. Pinch-resistant panels are designed to minimize these gaps, protecting fingers from being caught. This feature is especially important for households with young children who may touch the door while it operates.</p>
<h2>Manual Release Safety</h2> <p>The emergency release cord allows manual operation during power outages but can be a security vulnerability if accessible from outside. Modern systems include locks that prevent outsiders from pulling the release through the top of the door. If your door lacks this feature, aftermarket locks are available.</p>
<h2>Regular Testing and Maintenance</h2> <p>Safety systems only work when properly maintained. Test photo-eyes and auto-reverse monthly. Replace photo-eye sensors every 5-7 years regardless of apparent function. During annual professional maintenance, we test all safety systems thoroughly. Never disable or bypass safety features.they exist to prevent tragedy.</p>
