Scope

This European Standard specifies requirements, test methods and performance criteria for line detectors using an optical beam that detect smoke by utilizing the attenuation and/or changes in attenuation of an optical beam, for use in fire detection and fire alarm systems installed in buildings (see EN 54 1:2011).
This European Standard provides for the assessment and verification of constancy of performance (AVCP) of line detectors using an optical beam to this EN.
This European Standard does not cover:
- line detectors using an optical beam designed to operate with separations between opposed components of less than 1 m;
- line detectors using an optical beam whose optical path length is defined or adjusted by an integral mechanical connection;
- line detectors using an optical beam with special characteristics, which cannot be assessed by the test methods in this European Standard.
NOTE – The term "optical" is used to describe that part of the electromagnetic spectrum produced by the transmitter to which the receiver is responsive; this is not restricted to visible wavelengths.
