Dual-Power Design for Continuous Monitoring

The First Alert Dual-Power Carbon Monoxide Plug-In Detector is designed to work with any standard outlet, and it features battery backup to allow continuous monitoring of carbon monoxide levels in the event of a power outage. Simply place two AA batteries in the battery compartment, and if the power goes out, the backup will activate, monitoring carbon monoxide levels even during storms. A low-battery indicator light and alarm will sound when the batteries need to be replaced.

Advanced Electrochemical Sensor

The First Alert Dual-Power Carbon Monoxide Plug-In Alarm uses an advanced electrochemical sensor to detect elevated CO levels. This sensor offers increased sensitivity to carbon monoxide even at low levels. In the event of a false alarm, the silence/test button can be used to turn off the CO detector.

Backlit Digital Display is Easy to Read

The large backlit display on the carbon monoxide detector clearly shows the level of carbon monoxide in the room, as well as the power level of the backup batteries. The display is readable even in the dark and casts a calm blue light, making it ideal for use in a bedroom. The 6' power cord makes it easy to mount the CO monitor on a wall or position it on a shelf or nightstand.
