Plug-in Carbon Monoxide Alarm With Battery Backup
SKU: CO3-P01-T
Product Overview
Alerts you to CO threats
Carbon monoxide is an invisible, odorless, and deadly gas. Having working carbon monoxide alarms in your home is the only way to detect it. When carbon monoxide is detected, the alarm sounds a loud warning to alert you to the threat.
Reliable dual-power detection
The First Alert® CO3‑P01 Plug-In Carbon Monoxide Detector requires minimal installation. Simply plug the alarm into any standard electrical outlet on every level and in each bedroom for whole-home detection. In the event of a power outage, the battery backup powers the CO detector so it can continue to monitor your home for dangerous levels of carbon monoxide.
Simple and easy to use
Once the alarm has been installed, remember to test it regularly using the test button and change the batteries at least twice a year. A low‑battery alert will remind you when the batteries need to be replaced, and an end‑of‑life signal will alert you when the carbon monoxide detector has reached the end of its life and it's time to replace it. It’s important to replace your carbon monoxide alarm at least every seven years to help ensure continued detection.
Recommended placement
Install carbon monoxide alarms on every level and in every bedroom for whole-home detection.
Home CO sources
Carbon monoxide gas can be produced by any fuel-burning device such as furnaces, stoves, boilers, and dryers.
