Product Datasheets |
There is no legal or BSI requirement to test the CO detectors with a test gas. A weekly check with the test button is fully sufficient if you choose a quality CO detector. The test gas is offered as a 'belts and braces' option.
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.
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.
