Installing a carbon monoxide alarm could save your life.

Regular inspection and maintenance of appliances, vents, flues and chimneys are the best ways to protect you and your family from the hidden danger of carbon monoxide. For added protection install an audible carbon monoxide alarm.

Carbon Monoxide alarms are available from many hardware and DIY stores.

There are some points you need to be aware of to make sure your alarm effectively protects you.

Where to locate Carbon Monoxide Alarms

View this short video for advice on the best place to locate carbon monoxide alarms in your home including what rooms to install alarms and where to locate them. Video produced by Ei Electronics.

What type should I use?

Many different alarms are available but we recommend that the alarm;

  • Complies with European Standard EN 50291 - This should be marked on the box
  • Carries the CE Mark
  • Has an 'end of life' indicator - This indicator should not be confused with any 'fault' indicator
  • Carries an independent certification mark – For example a kite mark, this indicates that the alarm has been approved by an accredited testing and certification organisation.

We recommend that you do not use 'black spot' type passive indicators that change colour when carbon monoxide is present – these will not wake you up if carbon monoxide is present whilst you are asleep.

One alarm may not be sufficient

If all your fuel-burning appliances (including their exhaust flues and air supplies) are in the one room, then one alarm in that room may suffice. If the appliances/flues are located in more than one room, then an alarm should be fitted in each of those rooms.

Always follow the manufacturer's guidelines when installing alarms or have a qualified installer fit it for you.

Make sure the alarm can be heard

If the alarm(s) cannot be heard in any living rooms and in all bedrooms, more advanced alarms that include the provision for interconnecting them can be used. In this case, if one interconnected alarm detects CO, it will trigger the other units to also sound an alarm. This allows you to position extra alarms close to the living rooms and bedrooms, where they will be audible.

You should test the alarm regularly and replace it when it reaches the end of its life.

Carbon Monoxide alarms have a limited lifetime, and the manufacturer will specify when it should be replaced. We recommend alarms that incorporate an end-of-life indicator. Never hold on to a Carbon Monoxide alarm after its useful date has expired.

While Carbon Monoxide alarms may provide an extra measure of warning remember these are no substitute for regular inspection and maintenance of appliances, vents, flues and chimneys.

Always follow the alarm manufacturer's instructions and if any aspects are unclear, contact them directly for further guidance.
