J&R JREX-HSA Explosion-Proof Loudspeaker

The J&R JREX-HSA Explosion-Proof Loudspeaker is a heavy-duty horn speaker engineered to deliver clear public address, paging, and emergency alarms in hazardous industrial environments. Certified under ATEX and IECEx for Zone 1, 2, 21, and 22, this loudspeaker is ideal for high-risk oil and gas, chemical, and offshore operations where explosive gas or dust atmospheres are present. It features an advanced stainless steel wire mesh explosion-proof acoustic mesh that ensures maximum sound output with minimal attenuation while maintaining extreme mechanical strength.

Built for extreme field endurance, the JREX-HSA operates reliably in severe temperatures ranging from -40°C up to +65°C. It is housed in anti-static ABS with a rugged stainless steel mounting bracket and achieves an IP66 ingress rating to withstand heavy washdowns, dust, and corrosive sea spray. Available in SIP/VoIP (PoE/12V DC), constant voltage (70V/110V), and constant impedance (8Ω) configurations up to 35W, it seamlessly integrates into modern IP intercoms, traditional PA systems, and fire broadcast networks.
