The battery-operated intelligent alarm offers a fast response to real fires including slow smoldering and fast flaming while at the same time protecting against carbon monoxide and dramatically reduce the chance of nuisance alarms. With voice warning that clearly states the present danger: smoke or carbon monoxide. Combines the detection capabilities of an ionization smoke alarm sensor, which is more likely to detect smaller, less visible fire particles, with that an electrochemical sensor which is used to detect carbon monoxide. Both detection chambers work together in 1 alarm. When either sensor notices a potential hazard, it will communicate with the other.
