FAQs (14)
Q. Where should I install carbon monoxide detectors?

CO detectors should be installed near boilers and other potential sources of carbon monoxide. Keep a 1 to 3 meter distance to the boiler etc to avoid small start-up CO discharges to cause false alarms.

As you are likely to be most affected by CO in areas of your home that you spend the most time in it is advisable to install detectors in those areas as well, such as the living room and bedrooms.

It is also worth noting that while one detector is better than no detectors at all, larger homes may require several detectors to cover the property fully.

Which areas to avoid?

Do not install CO alarms above or below windows.

Although most kitchens contain fuel burning appliances it is not recommended to install your detector there. Kitchens can be quite steamy while you are cooking and this may affect the sensor in the CO detector. Similarly it is not recommended to install detectors in dusty areas such as workshops or garages.

For more information please watch our video guide

Q. Is this CO Detector compliant with all relevant standards to allow me to place it in a tenanted property as I am a landlord?

Yes, this CO alarm has been Kitemarked to EN 50291-1: 2010 and has been awarded a CE mark. It should be installed in line with the manufacturers guidance.

Q. What smoke alarm should I use in a bedroom with an en suite bathroom?

It is usually recommended to install an optical smoke alarm in a bedroom. This is because optical smoke alarms are slightly quicker at detecting slow smouldering fires that can originate from upholstery type materials and over-heated wiring. Also, an optical smoke alarm would be less likely to sound a false alarm than an ionisation would, if steam/water droplets were present from the bathroom. Detectors should be installed as central to the room as possible; however for your application I would also consider the position of the en suite to make sure that the detector is not in the direct path of the joining door. This is just to try and avoid the chances of a false alarm. No detector is designed for use in bathroom areas.

Q. What does it mean when the red alarm on the CO alarm bleeps every thirty seconds even after the batteries have been changed?

This would indicate that the CO alarm has come to the end of its life (about 7 years). If the CO alarm is not as old as this, this would indicate an error. In the case of the unit being less than 5 years old, we would recommend that you take it back to where you purchased it from for replacement. If you purchased it from us we will be happy to replace it for you.

Q. How do I safely dispose of my old smoke alarms?

Private households can therefore drop off their electronic and electrical fire safety waste at their municipal recycling centre when they are purchasing new products from us.

Value for money The fire angel carbon monoxide alarm has elaborate instructions for testing on a regular basis involving lighting a match to see if it goes off. The Honeywell alarm which i also purchased doesn't advise this you just test it each week by pressing a button. I doubt many people will follow the fire angel instructions. if id known about them i would have purchased 2 of the Honeywell alarms instead of going for the value bundle of a smoke alarm and co alarm. That is why I've given 3 stars ok - the fire angel smoke alarm is good.
