The ADT carbon monoxide detector is a wireless sensor that warns of a gas you cannot see or smell and reports to the control panel, so it must be placed well and enrolled correctly. For placement, follow the manual and the general guidance: put a detector on each level of the home and outside sleeping areas, near bedrooms, and keep it away from fuel-burning appliances' exhaust, a bathroom's steam, a kitchen's cooking fumes and a window or vent that causes drafts, since these cause false alarms or delay detection.
The checks in more detail
Do not cover it with a curtain or paint, and do not mount it where a cabinet blocks air. Carbon monoxide mixes with air, so the height is less important than the clear airflow, and the manual states the preferred position. To enrol it, put the panel into sensor or zone programming, protected by the installer or master code, then trigger the detector's enrolment, which for many models means fitting the battery or pressing a learn or test button as the manual says.
The panel beeps or shows the new device, and you name the zone and set its type as a carbon monoxide zone, which tells the monitoring center what to do on an alarm. SafeWise's guide says the panel sequence varies by model. After enrolling, test it with its test button and the panel's test mode, with the monitoring company told so that they do not dispatch help.
A carbon monoxide detector has a limited life, typically about five to seven years, and the manual or the back of the unit states the date, so write the replacement date near the panel. If it will not enrol, check the battery, the distance to the panel and that a free zone exists. If the alarm sounds, get everyone into fresh air and call the emergency services; do not stay to investigate. Test monthly and replace the detector when it reaches the end of its life.

Model-specific
What is true of this model and not of its siblings
- End of life
- CO detectors expire.
- Emergency
- If it sounds, get out.
- Choosing the location
- A carbon monoxide detector should sit where it can sample the air people breathe: outside each sleeping area and on every floor, with the manufacturer's height guidance followed. Avoid placing it beside a fuel-burning appliance, a window, a vent or a bathroom, where spikes and humidity cause false alarms. Pair it near the panel first, then carry it to its place and check the signal in the app before you fix it down.
- After pairing
- Name the detector by room, test it with the test button and the system's test mode and write the date of installation on the back. Carbon monoxide detectors have a finite life, usually the number of years printed on the unit, so note when it must be replaced.
