Mains powered CO alarm with electrochemical sensor, part of the same interlinked system as your smoke and heat alarms.

The Ei3018 detects carbon monoxide from boilers, gas fires, cookers and solid fuel stoves and can be interconnected with the rest of an Ei3000 fire system, so a CO event in the boiler cupboard sounds every alarm in the property. It meets BS EN 50291-1:2018 and the requirements of the Smoke and Carbon Monoxide Alarm Regulations for rented homes.
