Q. Where should I install carbon monoxide detectors?
A. 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.
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?
A. 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. How do I safely dispose of my old smoke alarms?
A. Safelincs is signed up to Valpak's WEEE (Waste Electrical and Electronic Equipment) Distributor Take-Back Scheme (Registration ID: 7370). 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. To find your nearest recycling centre, please visit www.recycle-more.co.uk.
Q. How long do the batteries last in smoke alarms?
A.
The 9V alkaline batteries last 12-18 months. Lithium batteries will usually last 5x longer than their alkaline counterparts, achieving around 5 years lifetime. Some lithium cells are also rechargeable, and when used in a mains-powered alarm may last for the entire functional lifespan of the alarm. Newer alarm models may also feature a "sealed" lithium battery. These batteries are specialist components which are designed to not be removed or need replacing by the user, and have been tested by the alarm manufacturer to ensure they last for the lifetime of the alarm.
Please Note: the actual lifetime of your batteries depends on how often the alarms are tested or activated, as sounding the alarm draws more power than when the alarms are "waiting" to detect fire. You should also read your alarm's manual to make sure you only use the recommended types and brands of batteries, as failing to follow these instructions may cause the alarm to malfunction, not alerting you in the event of a fire, and might also invalidate the warranty.
Q. What is the best way to test my alarm?
A. We recommend testing alarms by pressing the test button built-in to the unit, as this is designed to simulate the detection of the target stimuli (usually smoke, heat, or CO) at the alarm sensor. You should test your alarms regularly to ensure they are protecting building occupants, preferably every week. For more detailed guidance, check the manual included with your alarm.
Q. What are the regulations to testing CO detectors? Do I need to use test gas?
A. 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.

Protecting my family and home
Every household should have a carbon monoxide detector . They can save lives . The First Alert detector is easy to set up , is small so it can fit on top of a cupboard or looks neat and tidy on a wall. Testing the alarm gives a loud beep so would be easy to hear if the alarm goes off . I am very pleased with the quality of my product
