• Hush Feature - Temporarily silences nuisance alarms for approximately 9 minutes and will not allow hush mode unless the unit is in alarm mode.
The 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. Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. 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.
