The universal strobe light sirens fulfil the basic requirements of the ATEX Directive (94/9/EC) and have been approved for use in zones 1 and 2, as well as 21 and 22 explosion hazard zones. They are intended for operation in heavy-duty conditions on land and at sea. They are fixed to a robust, pre-drilled stainless steel plate coated with black epoxy paint or anti-corrosive glass reinforced plastic (GRP). Standard cabling has been solved such that the visual alarm and the loudspeaker are supplied at the same time from one input. The sound level of the loudspeaker reaches up to 115 dBA within the distance of 1 metre. The strobe light sirens are available with xenon, incandescent, fluorescent, or LED light sources.
