How to Install a Garage Door Opener Safety Beam

What You'll Need
Sensor kit
Wood lags

Installing a sensor on your garage door opener is a very important thing to do to ensure safety of your pets and family. This sensor uses a safety beam to detect if there is something in the path of a garage door. It contains an inferred device, as well as a receiver.\ These items are attached to both sides of the garage door frame. They send a safety beam to one another, so there is no gap or separation in the beam of light. When something disrupts the beam, the receiver gets the information and sends it to the garage door opener it self. The garaged door then stops closing and opens back up. This mechanism has been known to save lives. A garage door is heavy and if an animal or child is under it while closing there is a strong risk of injury or death. Read the steps below on how to install this great safety feature.

Step 1 - Unplug

The first thing to do is to ensure your safety. You will want to unplug the garage door opener unit from the plug in the wall. Make sure there is no power going to the unit before you start anything.

Step 2 - Attach the Brackets

Take one of the brackets out of the packaging and attach it to the door frame on either the left or right side. The brackets should be placed about 5 inches from the floor and out of the way of the door's track.  

Attach with wood lags. Then you can move on to the other side and repeat those same exact steps. You will want to make sure that the brackets are attached at the same level on each side. If the brackets aren't level with one another, then the devices won't be either, causing the safety feature to malfunction. 

Step 3 - Attach the Sensor

Now it is time to attach the sensors to the brackets. You will want to take your bolts, as well as the wing nuts and attach the sensors to the brackets.

Attach one device to each side, making the sensors face one another. This is where it makes a difference if you have stayed far enough way from the doors track. If it is to close to the track, the door will trigger the safety feature and create a false stop.

Most brackets have a couple different slots to bolt your sensor into. Make sure it is bolted securely before moving on.

Step 4 - Attach the Wire

There is also a wire contained in the kit you have. That wire needs to be connected to each sensor, as well as the opener. Wire according to the instructions, and then staple the wire to the wall. Using insulated staples is the best option.
