Fire detection and fire alarm system - Part 31: Multi-sensor fire detectors - Point detectors using a combination of smoke, carbon monoxide and optionally heat sensors
|Publication Date:||1 March 2012|
|ICS Code (Fire protection):||13.220.20|
This European Standard specifies requirements, test methods and performance criteria for point-type multisensor fire detectors for use in fire detection systems installed in buildings (see EN 54-1:1996), incorporating in one mechanical enclosure at least one optical or ionization smoke sensor and at least one carbon monoxide (CO) sensor and optionally one or more heat sensors. The overall fire detection performance is determined utilizing the combination of the detected phenomena.
This European standard specifies the evaluation of conformity (EoC) and the marking of the products concerned (i.e. multi-sensor fire detectors).
Multi-sensor fire detectors having special characteristics suitable for the detection of specific fire risks are not covered by this 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 standard does not define a test or assessment method).
NOTE Certain types of detector contain radioactive materials. The national requirements for radiation protection differ from country to country and they are not specified in this standard.
