Setup

• Make sure that your ADT Security Hub is disarmed

before connecting a new device.

Take the ADT Carbon Monoxide Alarm to where you

intend to mount it after setup.

2. Use the SmartThings app on your smartphone to

select the “My Home” tab. Select "Things", and then

“Add a Thing".

• 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 the ADT Security Hub, and the position

and number of other connected devices.)

• Make sure that you only setup one new device

at a time.

• Do not remove the tab until you are ready to

setup the detector.
