Genie Safe-T-Beams Explained

Genie Safe-T-Beams Explained

The garage door safety sensors are designed to ensure maximum safety for your garage door opener operation. The Genie garage door safety sensor kit (Safe-T-Beams) uses an invisible infrared beam across the opening of the door, the system detects any object passing through the infrared beam of light and automatically reverses the closing garage door. The Genie Safe-T-Beam system is required by US Law as of 1993.

However, the Genie Safe-T-Beam kit is self-diagnostic. If there is an issue or obstruction there is a series of garage door opener light flashes or small lights on the safety sensors to let you know what the issue could be (see chart below). If you are experiencing a garage door that will not close and a blinking garage door opener light you may have an obstruction of the Safe-T-Beam infrared light. If there is no physical obstruction you may have light interference. If the sun or another bright source of light shines into the garage door safety sensor lens it can cause a false positive and reverse the garage door. This can be a nuisance but good news, there is an easy fix available.

The Genie Version 2, Safe-T-Beam system (Model GSTB-R) has a lens cover that protects from alternative light interference, as seen in the picture below. This updated version should eliminate any false positive safety sensor signals. This is a very easy upgrade to your existing Genie garage door opener that should only take a few minutes to install. You can reuse your existing wiring and mounting locations. You simply remove the wires from the current Safe-T-Beam sensors and unscrew them from the wall. Then reconnect the wires and remount to the wall. The garage door safety sensor beams should still be lined up. If not loosen the mounting to the wall slightly and realign them by hand until both the red and green lights are on both sensors (one each on the left and right sensors themselves).

You have just successfully upgraded your Genie Safe-T-Beam system!
