Résumé

ISO 7240-12:2014 specifies requirements, test methods and performance criteria for line-type smoke detectors for use in fire detection systems installed in buildings. The detectors consist of at least a transmitter and a receiver and can include reflector(s), for the detection of smoke by the attenuation and/or changes in attenuation of an optical beam.

ISO 7240-12:2014 does not cover

  • line-type smoke detectors designed to operate with separations between opposed components of less than 1 m;
  • line-type smoke detectors whose optical path length is defined or adjusted by an integral mechanical connection;
  • line-type smoke detectors with special characteristics, which cannot be assessed by the test methods in this part of ISO 7240.
