Set Up and Connect the ADT Door and Window Detector

For everybody, safety is the number-one priority. So thankfully you've got the tools you need to protect your loved ones with the ADT Door and Window detectors. Give potential intruders the boot and guard your home by setting up door and window detectors. 

Door and Window Detectors

Is that a shadowy figure lurking near your door? No need to panic, you have your door and window detectors set up. We’ll walk you through it right here.

There are two ADT Door and Window Detectors in the ADT Home Security System Starter Kit and each one consists of two parts. Set up the detectors one at a time and do not remove the tabs marked “Pull This Tab” until instructed below.

  1. Take the first ADT Door and Window Detector to the door or window where you intend to mount it.

    Make sure you are within 350 feet of the ADT Security Hub. Exact range depends on your home’s construction, the environment, the position of the ADT Security Hub, and the position and number of other connected devices.

  2. Use the SmartThings app on your phone to select My Home and then touch Add a thing.

  3. Use the SmartThings app to scan the QR code on the front of the detector and then follow the on-screen instructions to complete setup.

    You can also enter the code manually.

  4. Remove the tab on the detector marked Pull This Tab.

  5. Place both parts of the detector on your door or window as shown. For double doors, place the smaller part of the detector on the most-used door and the larger part on the least-used door.

  6. Make sure that the alignment marks on both parts of the detector are aligned and facing each other, and that both parts of the detector are less than 0.5 inches apart when the door or window is closed.

  7. Make sure the detector is placed at the top of door or window frames to avoid accidental damage to the detector.

  8. Use the pre-applied adhesive tape to attach both parts of the detector to your door or window.

    Make sure all surfaces are clean and dry, and make sure to place both parts of the detector correctly as the adhesive tape will be difficult to remove.

  9. If it’s difficult to align both parts of the detector properly, you may want to adjust the height of the magnet by squeezing the tabs on the side or by adding the supplied spacer.

    To add the spacer:

    • Insert the spacer pin into the magnet base slot.

    • Slide the spacer forward to lock it onto the magnet.
