Carbon Monoxide Alarms
As an extra safeguard, you can buy carbon monoxide (CO) alarms. Battery operated alarms are also available for travelling, or using in caravans, boats and tents. CO alarms can be purchased for about £20 from most DIY stores, some supermarkets or from professional merchants, engineers and energy companies.
The approval standard which now applies in the UK (and across Europe) is the
European Standard EN 50291.
Note For recreational vehicle usage (caravans, motorhomes, boats) a new member of the standard family has some additional tests, this is EN 50291-2. Camping in tents was not considered by the standards writers, as this was not a known hazard at the time of writing.
Combined CO and smoke alarms
There are now three fully compliant combined smoke and CO alarms on the market, Kitemarked by BSI to both EN 50291 for the CO function and EN 14604 for the smoke function. CoGDEM is the Council of Gas Detection & Environmental Monitoring, i.e. a club of manufacturers that make CO alarms etc. Reputable manufacturers such as Kidde and Sprue have models which CoGDEM has checked, and also Nest (not a CoGDEM member so not checked by CoGDEM). Up to a few years ago, it was impossible to design one combined unit that would meet both standards, but innovation has helped to change this situation.
The optimum siting for a CO alarm and a smoke alarm might not always be identical. For example, in a good many homes the correct location for the CO alarm would be the kitchen if the boiler and gas cooker are both in that room. But it might not be appropriate to fit the smoke alarm there in case of multiple triggering during normal cooking processes. However, newer generations of smoke alarm use optical sensors which manufacturers claim are ‘toast-proof’.
CoGDEM is still cautious about recommending combined smoke and CO alarms unless the application is for a smaller home such as a bedsit, studio apartment, open-plan home where the locations for both the smoke and CO alarm can be fitted together and usually on the ceiling.
Innovations such as these are what the alarm industry does all the time, and the standards and test labs evolve to meet the innovation. Soon there will be a combined heat detector and CO alarm so that use in kitchens doesn’t cause false triggering of the fire detector (heat sensor).

All units benefit from a number of new features including:-
“Ventilate*” pre alarm function, low level monitoring mode,
memory function, upgradable to wireless connectivity and
completely sealed and tamperproof (IP44 rated)..
*The “Ventilate” pre alarm function, if required, needs to be manually activated by the user when they first turn the unit on (see manual) and then will flash the blue ventilate light once 25% of the full alarm requirement is reached (time and concentration). Eg, if 43ppm CO is present the blue ventilate light will flash after 15-23 minutes. This is effectively advising people to open doors and windows to “ventilate” the area as the level of CO is higher than it should be but not enough to trigger the full alarm.
The XC100 and XC100D also benefit from the new and unique “Action Text” feature which gives a clear indication to the customer of what to do/who to call in the event of a full alarm.

CoGDEM www.cogdem.org.UK CoGDEM is a trade association – this is the professional organisation that CO alarm manufacturers are members of, so that the industry can speak with one voice and standards can be maintained. CoGDEM also represents manufacturers of other gas measuring instruments such as flue gas analysers and workplace monitors.
We do NOT recommend cheap black spot detectors because they do NOT have an audible alarm. There is no British or European Standard for black spot detectors, they only last a few months, and they have been found to be unreliable. An audible alarm could rouse you from a CO stupor and save your life. At around £20, an audible alarm will save you money over its lifetime (5-7 years) compared with the black spot detectors that have to be replaced every few months.
Also, Ann Brennan aged 19, a Durham student, had a black spot detector and it didn’t save here from dying from CO. An audible alarm could rouse you from a CO induced stupor and save your life, or that of a loved one!

Due to the type of sensor that is required for flammable gas detection, currently there seem to be no approved flammable gas alarms on the market that can run effectively from only internal batteries because the sensor uses too much power and would drain these batteries relatively quickly. The unit does therefore need to be mains powered or in some cases can be run from a 12VDC power supply (such as a car battery). Recently (Jan. 2015) we have been given more reasons for the lack of a plug in natural gas alarm. From a technical perspective, natural gas is lighter than air so will fill a room from the ceiling downwards. Therefore if a detector plugged straight into a socket this would be in completely the wrong place to detect this gas as plug sockets will either be at floor level in most rooms or perhaps at chest height such as in a kitchen.
A natural gas alarm needs to be installed within 12 inches from the ceiling to provide the correct protection and the EN50194 standard also indicates this.
