This battery operated Carbon Monoxide Alarm can prevent you for the effects of a gas that is one of the most deadly gases known. Carbon Monoxide is poisonous, odourless, invisible and you can neither smell or feel the gas.It is most common around inefficient burning devices such as boilers, and fires(whether it is gas, wood, coal or oil burning).We suggested you install a CO alarm in every room, including basements and attics.When the unit detects CO leakage, it will provide a loud 85db sound and a steady red light indicator will be visible.In normal conditions, the red indicator will flash every 30 seconds.
