Fire detection and fire alarm systems - Part 12: Smoke detectors - Line detectors using an optical light beam

Scope

This European Standard specifies requirements, test methods and performance criteria for line smoke detectors utilising 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:
¾ Line smoke detectors designed to operate with separations between opposed components of less than 1 m;

¾ Line smoke detectors whose optical path length is defined or adjusted by an integral mechanical connection;

Line smoke detectors with special characteristics, which cannot be assessed by the test methods in this European Standard.
