The IS IR3 Flame Detector is designed for harsh environments in either indoor or outdoor ap- plications. It is sensitive to low frequnency ickering IR radiation emitted from ames during combustion. The sensor operates even through a layer of oil, dust, water vapour or ice. These detectors have been approved by Baseefa to standards EN50014, EN50020 and EN50284. The requirements of Directive 94/9/EC, the Atmosphere Explosives ATEX directive have also been met.
