At OTC, the largest US oil and gas show, E2S Warning Signals are launching three major new families added to its portfolio of more than 250 different explosion proof and intrinsically safe warning devices for use in hazardous locations. The new ‘D1x’ range of alarm horns, PA loudspeakers and integrated alarm horn/Xenon strobe warning units employ the latest electronic technology and acoustic engineering in robust, marine grade, LM6 aluminium enclosures. Designed to create the most effective warning signals available for use in Class I/II Division 1, Zone 1 & Zone 20 environments, the UL/cULs approved alarm horns and combined units are available with traditional directional flare horns or omni-directional radial horns that generate a uniform 360° sound dispersion.
