Intrinsically safe loudspeakers and hazardous area EX-rated audio solutions are designed to deliver clear, reliable sound where safety is critical. Built to withstand extreme conditions, these explosion-proof horn speakers and aluminium ceiling speakers are chemical-resistant, corrosion-proof, fireproof, and highly durable against water, salt, and chlorine.

Engineered with ATEX and IECEx certifications for Zone 1, Zone 2, Zone 21, and Zone 22 environments, intrinsically safe loudspeakers prevent ignition risks from sparks or heat in atmospheres containing flammable gases or combustible dust.

Available for use on 100-volt line systems with power ratings from 6W to 25W, they ensure high intelligibility for voice announcements while maintaining full system integrity during emergencies.

These robust speakers are ideal for life safety and public address applications in petrochemical plants, oil and gas refineries, pharmaceutical facilities, marine vessels, offshore platforms, and other high-risk industrial or onshore/offshore locations.

Whether you need compact marine horns, long-flare explosion-proof horns, or discreet ceiling speakers, our range provides dependable performance in the most demanding hazardous environments.

When ordinary speakers simply aren't safe enough, choose certified intrinsically safe loudspeakers that protect both people and property while delivering crystal-clear audio. Explore our full selection of ATEX-rated, flameproof, and MED-compliant* hazardous area loudspeakers today.
