AtlasIED explosion-proof horn products are designed for voice and signal communication in classified hazardous locations. The line includes HLE and MLE compression drivers approved for specific Class I, Division 1 gas groups plus HLE/MLE projector horns.
Hazardous-location selection must match the exact area classification, gas group, listing and installation method. HLE and MLE drivers differ in power and approved groups, and only specified HLE/MLE horn projectors are listed for use with those drivers.
Do not select an explosion-proof loudspeaker from wattage alone; confirm the project's hazardous-location classification and authority requirements first.
