This British Standard specifies general requirements for the construction, testing and performance of electrically operated gas detection apparatus, designed for continuous use in domestic premises, to give a warning alarm in the event of a hazardous accumulation of carbon monoxide (CO). Such apparatus is aimed at enabling a room occupant to react before being exposed to significant risk, but without creating false alarms (see annex A).
NOTE 1. Conformity to this standard does not imply that the apparatus is suitable for non-domestic installations.
NOTE 2. Apparatus conforming to this standard may not protect people who are at special risk from CO exposure, by reason of age or medical condition for example.
