ADET
The Optical smoke detector OC05Ex analyzes an atmosphere by reflection of a light on the particles of smoke according to TYNDALL effect.
It detects especially the cold and visible smoke particles (0,3µm to 2µm) produced in the early stages of a fire. The threshold of response of alarm is regulated to obtain the value m=0, 180db/m ± 0, 03 according to standard EN54-7. OC05Ex includes a developed technology (microprocessors, smd components) which means precision and high reliability.
OC05Ex is a conventional Atex detector and it can work in a intrisically safe area.
