Line detectors using an optical light beam Ingestion-build-98192 It also includes requirements forBS EN 54 12: 2002 specifies requirements, test methods and performance criteria for line smoke detectorsutilising the attenuation and or changes in attenuation of an optical beam, for use in fire detection systems installed in buildings. This European Standard does not cover: line smoke detectors designed to operate with separations between opposed components of less than 1 m line smoke detectors whose optical path length is defined or adjusted by an
