Carbon Monoxide Alarms

Carbon monoxide is a silent threat. It’s a deadly gas with no smell, taste or colour, and it’s produced when fuels like gas, wood, or coal burn incompletely. Without a carbon monoxide alarm, it can go completely undetected.

Installing an alarm in any room with a fuel-burning appliance—such as a boiler, cooker, or open fire—can quite literally save your life. Our range of CO alarms is designed to provide an early warning, giving you peace of mind and vital protection around the clock.
