Smart carbon monoxide alarms can connect to a compatible security panel through wired or wireless communication, allowing the system to report alarms, tamper events, and low-battery conditions. Some models also work with smart home platforms or mobile apps to provide remote notifications, while built-in sounders, visual indicators, or interconnected alarms alert people onsite.

Choose battery-powered smart carbon monoxide alarms where wiring is limited or you need flexible placement, while hardwired alarms fit projects with existing electrical connections and may include battery backup. Choose wireless smart carbon monoxide alarms when the detector needs to communicate with a compatible security or automation panel, especially for monitored alerts, system status, and installations where running cable is difficult.

Smart carbon monoxide alarms typically use a built-in audible alarm and visual indicators, such as flashing lights or LEDs, to alert people onsite when CO is detected. When connected to a compatible security panel or smart home system, they can also send alarm signals to the panel, monitoring station, or mobile app, depending on the system setup.

Install smart carbon monoxide alarms on each residential level, outside sleeping areas, and near rooms with fuel-burning appliances, while keeping them away from vents, windows, and direct appliance exhaust. In commercial spaces, place alarms in occupied areas, sleeping rooms, and near fuel-burning equipment or mechanical rooms, following local codes and the manufacturer’s placement instructions.
