ADT Carbon Monoxide Alarm

The ADT Carbon Monoxide Alarm monitors for carbon monoxide in your home. When Carbon Monoxide is detected, the alarm sounds and a notification is sent to your ADT Security Hub. With SmartThings, your ADT Security Hub can send an alert to your smartphone, or initiate optional ADT professional monitoring services (additional fees apply).

Note: The ADT Carbon Monoxide Alarm requires the ADT Security Hub.

How to connect the ADT Carbon Monoxide Alarm to the ADT Security Hub

Take the Carbon Monoxide Alarm to where you intend to mount it after setup. Make sure you are within 350 feet from the ADT Security Hub. (Exact range depends on your home’s construction, the environment, and the position of the ADT Security Hub.) Also make sure your ADT Security Hub is disarmed before connecting a new device.

In the SmartThings mobile app:

  1. Tap My Home
  2. Under Things, tap Add a Thing at the bottom of your Things list
  3. Tap the plus icon at the bottom of the screen
  4. Tap Install Code
  5. Scan the QR code on the front of the device
    • If scanning the QR code doesn’t work, enter the 16-digit Installation code manually
  6. Take off the back cover and remove the battery tab from the device
    • If the battery tab has already been removed or the device LED is not blinking, see the “How to reset the ADT Carbon Monoxide Alarm” section below
  7. When the device is discovered, it will be listed at the top of the screen
  8. Tap the device to rename it and tap Done
  9. When finished, tap Save
  10. Tap Ok to confirm

 

Remove the QR code from the front of the alarm and attach it inside the included Setup Guide for future reference.

Note: If you have an ADT professional monitoring service activated, additional testing is required whenever you connect a new device. Follow the in-app steps when prompted.

 

How to reset the ADT Carbon Monoxide Alarm

If the ADT Carbon Monoxide Alarm didn't connect successfully when you removed the battery pull-tab and scanned the QR Code, reset the device before you try connecting it again.

  1. Remove the back cover
  2. Press and release the button on the circuit board twice
  3. Press and hold the button for approximately 5 seconds until the LED on the front turns solid
  4. After a few seconds, the LED will start to blink slowly, indicating it is in pairing mode for 3 minutes

Next, follow the steps above in “How to connect the ADT Carbon Monoxide Alarm to the ADT Security Hub.” After scanning the QR code, the ADT Security Hub should discover your device within a couple of minutes.

 

How to place the ADT Carbon Monoxide Alarm

Install the ADT Carbon Monoxide Alarm in a place where the alarm can be heard easily. Ideally, a carbon monoxide alarm should be installed in:

  • Every room containing a fuel burning appliance
  • Within 10 feet of a sleeping area
  • On every floor of the building

Note: The ADT Carbon Monoxide Alarm is intended for use in ordinary indoor locations of family living units. It is not designed to measure compliance with Occupational Safety and Health Administration (OSHA) commercial or industrial standards. Do not place the ADT Carbon Monoxide Alarm in any of the following areas:

  • In the immediate vicinity of a cooking appliance (keep it at least 5 feet away from it)
  • Outside the building
  • In an enclosed space, e.g. in or below a cupboard
  • In a damp or humid area
  • Directly above a sink or cooker
  • Next to a door, window, air vent, or anywhere it could be affected by drafts
  • Next to an extractor fan
  • Over heat sources such as radiators or hot air vents
  • Where it would be obstructed, e.g. by curtains or furniture
  • In an area where the temperature could drop below -50°F or above 104°F
  • Where it could be easily knocked or damaged, or accidentally turned off or removed
  • Near paint, thinners, solvent fumes, or air fresheners
  • Where dirt or dust could block the detector
  • In a bathroom or other areas where it may be exposed to water splashes, dripping or condensation, e.g. above an electric kettle

 

How to mount the ADT Carbon Monoxide Alarm

Once you've found an acceptable location, mount the ADT Carbon Monoxide Alarm:

  1. Install the mounting base using the two screws and anchors provided
  2. Fit the alarm inside the base by aligning it over the base, then turn the alarm in a clockwise direction until it clicks into place. The three LEDs will flash while the alarm powers up
  3. Test the alarm after completing installation

Note: See the Setup Guide that came packaged with your ADT Carbon Monoxide Alarm for safety tips.

  3. Tap the gear icon
  4. Select the ADT Carbon Monoxide Alarm

How to replace the ADT Carbon Monoxide Alarm's batteries

The alarm regularly checks for low batteries and will alert you if a low battery is detected. The alarm will also beep and the yellow LED will flash to warn you that the batteries must be replaced.

Note: Use only batteries specified. Use of different batteries may have a detrimental effect on the carbon monoxide alarm. Removal of the batteries will render this alarm inoperative.

  1. Remove the alarm from its mounting base by twisting it counterclockwise, and then remove the battery cover
  2. Remove the old batteries and install two new AAA batteries. Be sure to install the batteries correctly
  3. Attach the alarm to the mounting base by matching up the alignment marks and then turning the alarm clockwise until it clicks into place
