Go with CO
Wall mount, using the two small screws provided, or leave portable to be positioned where required or taken on holiday.
The electrochemical sensor in the FireAngel CO-9D Carbon Monoxide alarm provides instant alerts to dangerous levels of the CO. It's been rigorously tested and approved by BSI Kitemark to ensure the highest level of safety for your home.

The unit comes with a sealed, tamper proof battery that will last the lifetime of the alarm. The sensor within the unit will deteriorate after 7 years, so to ensure you're protected we recommend you replace the unit after this time.

The CO-9D alarm has been designed to conform to the EU standards - EN 50291-1: 2010 + A1:2012 and EN 50291-2: 2010. The alarm is also suitable for installation in caravans, motor caravans and boats, following advice from BS EN 50292-2013.

FAQ's
A Carbon Monoxide (CO) alarm is the only way to alert residents to the presence of Carbon Monoxide within a property. A CO alarm via an audible alert
CO also known as ‘the silent killer’ is a gas which cannot be seen, tasted or smelt but can result in CO poisoning and illness or in some cases death. CO forms when the fuel in products, such as boilers, fires and ovens does not burn completely. Regular servicing of these products can reduce the risk of CO being present but it cannot completely remove the risk.
Our FireAngel Carbon Monoxide (CO) detectors are designed so that alarms can be wall-mounted or left freestanding within a property. Ideally, a CO alarm should be installed in every room with a fuel-burning appliance e.g gas hob, open fire, boiler. Additional alarms may be installed to provide adequate warning for occupants in other rooms, by placing alarms in rooms in which they spend considerable time whilst awake e.g living rooms, bedrooms, kitchens.

The common sources of Carbon Monoxide (CO) are cookers, fires, boilers, oil and gas boilers, portable generators, oil or solid fuel cookers, gas or paraffin heaters, barbecues (BBQs), clogged chimneys, wood or gas fireplaces, cigarette smoke or any fossil fuel-burning appliances.
Using a gas safe engineer to regularly service these items will help reduce the risk of CO in a home but it will not completely remove the risk. The only way to detect CO in your home is to install a Carbon Monoxide detector with an audible alarm. Gas safe engineers can be found via the ‘Gas Safe Register’ – this is an official list of businesses that are legally permitted to carry out gas work.
