Kidde 10-Year Worry Free Smoke & Carbon Monoxide Detector, Hardwired with 10 Year Battery Backup & Voice Alarm

he Kidde i12010SCO is a hardwired combination smoke and carbon monoxide alarm that contains a 10-year, sealed battery backup. This alarm uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you from carbon monoxide and dramatically reduce the chance of nuisance alarms. The Intelligent sensor technology combines the detection capabilities of an ionization smoke sensor - which is more likely to detect smaller, less visible fire particles, like those produced by flaming fires - with that of an electrochemical sensor, which is used to detect CO. When either sensor notices a potential hazard, it will communicate with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. This constant communication enhances the alarm's overall performance in all fires, and significantly reduces the potential for a nuisance alarm.The i12010SCO contains a 10-year tamper proof backup battery that eliminates the need for battery replacement, and ends worry over unauthorized battery removal. The alarm provides continuous protection from smoke, fire and carbon monoxide, even during power outages. At the end of alarm life, the unit will chirp, indicating the alarm is in need of replacement. The end of life chirp can be temporarily silenced, allowing for replacement at a more convenient time.|Hardwired 120-volt power source with 10-year, lithium battery back-up|Protection during power outages and no low battery chirps|Test/hush button: silences the unit for approximately 9 minutes|Voice warning alerts of "Fire!" when a smoke or fire hazard is present, "Warning!
