This European Standard specifies requirements, test methods and performance criteria for point-type multi-sensor fire detectors for use in fire detection systems installed in and around buildings (see EN 54 1:2011), incorporating in one mechanical enclosure at least one carbon monoxide sensor and at least one heat sensor and where the overall fire detection performance is determined utilizing the combination of the detected phenomena.
This European Standard provides for the assessment and verification of consistency of performance (AVCP) of multi-sensor fire detectors using a combination of carbon monoxide and heat sensors to this EN.
Multi-sensor fire detectors using carbon monoxide and heat sensors having special characteristics suitable for the detection of specific fire risks are not covered by this European Standard. The performance requirements for any additional functions are beyond the scope of this standard (e.g. additional features or enhanced functionality for which this European Standard does not define a test or assessment method).
