Lifesaver A loud 85 decibel alarm and a flashing red LED effectively provide an instant alarm signal when dangerous amounts of carbon monoxide gas are detected. AA batteries included. Equipped with batteries, there is no need to buy additional batteries, just install batteries, test carbon monoxide detector, and then mount it on the desired wall or ceiling.
KEEP YOUR SAFETY Place the carbon monoxide detector near the boiler, gas fire and room to prevent carbon monoxide leaks. The display shows you not only whether carbon monoxide leaks, but at what speed. Every house with wood, coal, gas or oil fires should have one.
International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
Carbon monoxide monitor Continuous monitoring for CO. Digital display of CO values from 20 ppm. Detector alarms from 50 ppm. The alarm time depends on the level of carbon monoxide concentration and the screen of the carbon monoxide alarm accurately measures the concentration of carbon monoxide and its concentration data. The carbon monoxide detector notifies you immediately when the concentration reaches a certain level, minimising false alarms.
