Set Up and Connect the ADT Smoke Alarm

Whether you’re in your bedroom fast asleep or out of town, ease the fear of experiencing a house fire when you set up your ADT Smoke Alarm. It alerts you of smoke and extreme temperatures so you can take swift action.

Smoke Alarm

Get your ADT Smoke Alarm set up so you can start protecting your home in case of fire. We'll tell you everything you need to know.

Before we start, just a few things to keep in mind:
• Make sure you are within 350 feet from the ADT Security Hub. Exact range depends on your home’s construction, the environment, the position of your ADT Security Hub, and the position and number of other connected devices.
• Make sure your ADT Security Hub is disarmed before connecting a new device.
• Make sure that you only set up one new device at a time.
• Do not remove the battery tab until you are ready to set up the detector.

  1. Take the ADT Smoke Alarm where you intend to mount it after setup.

  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 alarm and then follow the on-screen instructions to complete setup.

  4. Remove the tab on the smoke alarm marked Pull This Tab. The yellow LED will blink once, followed by a single blink of the red LED.

  5. Remove the QR code from the front of the alarm and attach it inside the ADT Security Hub User Guide for future reference.

  6. To mount the smoke alarm to the ceiling, install the mounting base using the two screws and anchors provided.

    If ceiling mounting is impractical, smoke alarms may be mounted on a wall (if local ordinances permit) provided that:
    • The top of the detection element is between 6 and 12 inches below the ceiling.
    • The bottom of the detection element is above the level of any door openings.

  7. Fit the alarm inside the base by aligning it over the base, and then turn the alarm in a clockwise direction until it clicks into place.

  8. Test the alarm after completing the installation.
