EN 54-7 is the standard for point smoke detectors, the group to which the Tyndall light-scattering chamber belongs. EN 54-17 covers short-circuit isolators, here the isolator housed inside the detector.<\/p>\n<h3>Optical 41RFU100B versus heat detector 41RCS100B<\/h3>\n<p>Detector 41RCS100B: a black addressable heat detector of the same series, reacting to a fixed temperature threshold or a rapid rise. The optical detector reacts to smoke and has no heat element. Operating classes A1\/R, A2\/S and B\/S are programmed on the heat detector, which is certified to EN 54-5 instead of EN 54-7.<\/p>\n<p class=\"nj-rel\">Product code: 41RFU100B.
