The Combination Smoke and Carbon Monoxide Alarm uses an advanced electrochemical sensor to detect carbon monoxide leaks from multiple sources, including faulty fuel-burning appliances. A one-touch button silences false alarms and allows you to test the wireless interconnected smoke and CO detector for functionality each month. A low battery light and chirp sound will let you know when the batteries need to be replaced. Simply put two AA batteries into the detector and mount it on any wall or ceiling.
The battery-powered Combination Smoke and Carbon Monoxide Alarm requires no wiring to install. Earlier notification of fire or CO danger means you can escape to safety sooner. The wireless alarms communicate with each other through a radio frequency, so when one alarm sounds, all of them sound. The First Alert Battery-Operated Combination Smoke and Carbon Monoxide Alarm makes it easy to install multiple alarms around your home or office to create a safety network of detection.
