Safe egress in hazardous locations isn’t optional, it’s code. Our explosion proof emergency and exit LED solutions deliver clear, compliant wayfinding in Class 1 Division 1 & Division 2 environments, protecting people during outages, incidents, and evacuations.
Use explosion proof emergency and exit units wherever flammable gases, vapors, or combustible dusts may be present and life-safety egress must be maintained—oil & gas, chemical processing, marine/offshore, wastewater, and paint/finishing facilities. Look for fixtures with integral battery backup (for lights and exit legend), rugged NEMA/IP sealing, and hazardous-location listings such as UL844 and UL924 to ensure NEC/OSHA compliance in C1D1/C1D2 spaces.

Purpose-built for hazardous egress routes, EX-ES03 combines an LED exit legend with two high-lumen, fully adjustable emergency heads, so one unit handles both wayfinding and illumination under emergency power. Typical deployments include compressor rooms, tank farms, offshore platforms, stairwells, corridors, and pump galleries across oil & gas and chemical plants.
Hazardous-location listings: UL844 C1D1/C1D2 and dust classes; UL924 emergency lighting (select variants ETL listed)
Battery backup: 3-hour emergency duration; independent backup for the exit legend and for the twin spot heads (better redundancy during an event)
Adjustable beams: Two high-lumen spotlights adjust horizontally and vertically for targeted egress illumination
Ingress protection: NEMA 4X and IP66 enclosure; IK10 enclosure impact resistance (IK08 glass with metal guard) for harsh industrial and marine environments
Conduit-ready: Dual 3/4" NPT hubs to simplify hazardous routing and sealing
Legend options: Red or green EXIT legend; directional arrows/labels available; impact-resistant panel
Power & runtime: 5W per emergency head; 3–5W legend; typical input 100–277VAC (select DC options on combo variant)
Environment: Charge 0°–45°C; discharge –20°–60°C; sealed for wet locations; 50,000-hour LED life; 5-year limited warranty

The EX-ES03 provides 3 hours of emergency illumination. For best performance, charge for 24 hours before first use; thereafter the unit recharges automatically when AC power is restored.
Yes. Red or Green exit legends are available, with directional arrows/labels. The impact-resistant sign panel is designed for high visibility in industrial settings.
Standard installation is wall mount with expansion anchors and 3/4\" NPT conduit entry. Follow the hazardous-location instructions for sealing fittings and do not open the enclosure in an explosive atmosphere.
The enclosure is NEMA 4X/IP66 with IK10 impact resistance (IK08 glass with guard), suitable for wet/corrosive locations and offshore sites. Confirm corrosion-resistance requirements (e.g., salt-fog) with your MAES rep during specification.
The EX-ES03 carries a 5-year limited warranty. Use the push-test button to verify emergency function periodically. The LED boards/drivers are not field-replaceable, contact us regarding battery service and approved replacement packs.
