Fire detection and alarm systems for buildings - Specification for optical beam smoke detectors Ingestion-build-239834 Contents of BS EN 55024Summary BS 5839 5: 1988, a part of the BS 5839 series, specifies requirements, test methods and performance criteria for fire detectors utilizing attenuation of an optical beam for the detection of smoke aerosols. An optical beam detector may or may not include an external reflector but is distinct from a point detector in that there is no integral mechanical connection to define or adjust the optical path length. This specification covers beam
