E2S has introduced a new option for its BEx range of explosion proof horns. A new design of output horn turns the sound 90 degrees into a radial, omni-directional pattern without reducing the unit’s sound output levels. This is especially suited to combined horn/strobe units that are ordinarily installed with the strobe at the top and the horn facing downwards so that the sound output is pointing directly at the floor, limiting its range and impact. The radial horn offers a smaller footprint than the directional one, allowing the units to be installed in locations where space is restricted.
The new “-R” version can be specified for all existing BExhorns and combination units. The Four-stage, 45 tone BEx range is available in both EEx d and EEx de ratings, and is approved for use in gas Zones 1 and 2 and dust Zones 21 and 22. The family consists of 117 dB at 1m and 123 dB at 1m horns, the Hootronic versions that faithfully mimic the traditional electromechanical siren, buzzer and bell, 15 and 25 Watt loudspeakers and 5, 10, 15 and 21 Joule strobes.
