Common sources of CO include: \n• Oil and gas boilers \n• Portable generators \n• Oil or solid fuel cookers \n• Gas or paraffin heaters \n• Barbecues \n• Clogged chimneys \n\n\n\n\n\n\n• Wood or gas fireplaces \n• Cigarette smoke \n• Gas appliances \n• Any fossil fuel-burning appliance FireAngel are proud to support the carbon monoxide awareness campaign - Project SHOUT.\n\nThe Fireangel FA6813 is a 10 year Carbon Monoxide Alarm that''s supplied with replaceable batteries. The advanced electrochemical sensor has been designed to accurately measure low levels of carbon monoxide within your home. \n\nThe unit has been designed to either be wall mounted, using the two small screws provided, or left portable to be positioned where required. When left portable you''re able to take away with you on holiday, ensuring you''re protected at all times. The test button on the FireAngel FA6813 carbon monoxide detector has been designed to be easily located and pressed to make testing simple.\n\nThe FA6813 detector is suitable for private and rented homes in England, Wales and Ireland. Unfortunately as the batteries are replaceable it is not compliant with the new Scottish Fire & CO laws from February 2022. Carbon Monoxide is an incredibly poisonous gas which is emitted when fuel burning appliances burn incompletely. Carbon monoxide cannot be smelt, tasted or seen, and can be deadly - the only way to be alerted to CO is with an audible CO alarm.

It was just what I needed. I installed it with just 2 screws and sometimes you don't even need to screw it. It can be placed in the proximity of gas appliance. Ideal for a replacement.

Always use these

Use them in various places, reliable and easy to test. Like the function that they expire after a certain number of years. You then know it’s time to replace them.

Good value for a good alarm, bought to replace an earlier one that had come to the end of its stated life (although I bet it would still work).

I always use fire angel products, last alarm was over 10 years old and still working but as it was close to boiler and gas hob was looking a little tired.
Bought a new one and had it up and running in just a few minutes. I like the occasional flash as I can easily see it is working fine.

Keep safe and well
