Nosaukums<p>This document specifies requirements, test methods and performance criteria for line-type smoke detectors for use in fire detection systems installed in buildings. The detectors consist of at least a transmitter and a receiver and can include reflector(s) for the detection of smoke by the attenuation and/or changes in attenuation of an optical beam.</p> <p>This document is not applicable to:</p> <p>—    line-type smoke detectors designed to operate with separations between opposed components of less than 1 m;</p> <p>—    line-type smoke detectors whose optical path length is defined or adjusted by an integral mechanical connection;</p> <p>—    line-type smoke detectors with special characteristics, which cannot be assessed by the test methods in this document.</p> <p>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.</p>
