Carbon monoxide is odorless, tasteless and invisible, so an alarm provides a way to detect it in your home. This Kidde unit is designed for household placement on each floor and near sleeping areas, with options for a wall outlet, tabletop or wall-mounted position.

How does the Kidde detector alert you to carbon monoxide?

Its patented Nighthawk electrochemical sensor detects CO, and the alarm sounds at 85 dB when levels reach a dangerous point. The digital readout displays levels between 30 and 999 parts per million, refreshing every 15 seconds. Peak Level Memory retains the highest CO reading since the last reset and records when CO was detected or when the unit was tested.

• LED status light indicators show the alarm’s status.
• The Smart-Hush button silences the unit for approximately 8 minutes.

How can I position and power this CO alarm?

Plug the detector into a standard 120V AC outlet, use the included 8-foot power cord for tabletop placement, or wall-mount it. The included 9V alkaline battery provides backup power during an electrical outage.

• Place at least one CO alarm on every floor and in sleeping areas.
• Keep it at least 15 feet from cooking or heating appliances to help prevent false alarms.
