FIRE DETECTION AND FIRE ALARM SYSTEMS - PART 12: SMOKE DETECTORS - LINE DETECTORS USING AN OPTICAL LIGHT BEAM
This Malaysian 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 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 integral mechanical connection;
- Line smoke detectors with special characteristics, which cannot be assessed by the test methods in this Malaysian Standard.
