The First Alert CO500CNA-3ST Wireless Interconnected Carbon Monoxide detects elevated carbon monoxide levels and can work with compatible models to create a wireless alert system throughout your home. This wireless-enabled battery-operated detector alerts you by using a loud 85-decibel siren and that studies have shown to wake up children better than standard alarms. Wireless Interconnected technology allows other compatible First Alert wireless-enabled alarms located in separate areas of your home to communicate with each other, alerting you to a problem even when it’s on another floor. The carbon monoxide alarm features a sensor for increased accuracy.

Can Be Connected with Compatible Alarms for Enhanced Safety

The First Alert CO500CNA-3ST Carbon Monoxide Detector can be connected with multiple alarms around your home or office to create a safety network of detection (additional alarms sold separately). Compatible wireless alarms can communicate with each other through a radio frequency, so when one alarm sounds, all of them sound. Earlier notification of danger means you can avoid dangerous CO levels sooner.

Battery-Operated Alarm Installs Easily

The battery-operated wireless interconnected carbon monoxide detector requires no wiring to install. Simply put two AA batteries into the detector and mount it on any wall or ceiling. A low-battery light and chirp will let you know when the batteries need to be replaced. A one-touch button silences false alarms and allows you to test the CO detector for functionality.

Accurate Detection Technology

This carbon monoxide alarm uses an advanced electrochemical sensor to detect carbon monoxide leaks from multiple sources, including faulty fuel-burning appliances, blocked chimneys, and generators running inside or too close to homes.
