Alarms should adhere and carry British Standard BS EN 50291. There are two parts to this standard. Part 1 affects stationary use (e.g. in the home). Part 2 affects recreational vehicles such as caravans or boats.
Having more than one British Standard has created confusion for people trying to compare different models.
All the models we stock here at Co-Detect are CE approved and kitemarked to the appropriate version of the British Standard. We continuously monitor the quality and conformity of every single product we sell. You can be confident that buying from us you will have quality, branded and accredited alarms. You will be safe.
The Manufacturing Standards
The manufacturing standard covering carbon monoxide detectors is divided into two parts.
The previous standard BS 50291:2001 was superceded in April 2011 and split into two parts, part one covering domestic carbon monoxide detectors, and part two covering detectors for use in recreational vehicles (caravans, boats etc.)
The majority of carbon monoxide detectors bought are purchased for use within a standard domestic setting, and are intended to be stationary throughout their lifespan. Of course the home is not the only place where there is a risk of carbon monoxide poisoning, therefore there is also a range of ‘portable’ devices that are tested further to ensure they can withstand the conditions likely to be encountered if the product is used in a recreational vehicle.
Part 1 – Domestic
This part defines the test methods and performance requirements for ‘electrical apparatus for the detection of carbon monoxide in domestic premises’. It covers a wide range of performance and durability measures. It lays out the means and extent of testing for sensor reaction times, temperature resistance and minimum alarm volume levels.
This standard sets the base level for devices sold ‘for continuous operation in domestic premises’
You should ensure that a carbon monoxide detector purchased for the home conforms to either part one of BS EN 50291.
Part 2 – Recreational
This part defines additional testing required for carbon monoxide detectors, which are likely to be subject to movement or vibration during their lifespan. Therefore alarms conforming to this standard tend to be more robust than alarms simply carrying the part one f the British standard BS EN 50291.
With high publicity around carbon monoxide caused deaths in recreational settings (camping, caravanning, boating etc.) this standard is becoming more sought and common place. And now leisure users have a way of understanding quickly which carbon monoxide detectors will be suitable and keep them protected. You should always ensure that any carbon monoxide detectors for use outside of a standard domestic setting conform to part two of BS EN 50291.
The Manufacturing Standards
As well as the standards mapping out the required quality and performance levels of alarms for manufacturing purposes, there is also a standard, which defines best practice in terms of installation and maintenance.
