Explosion Proof Emergency & Exit Lighting (Class 1 Div 1 & Div 2 Certified)

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.

When to Choose Explosion Proof Emergency and Exit Lighting, C1D1, C1D2, UL924

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.

Explosion Proof Emergency & Exit Lighting FAQs

What is the battery backup runtime and typical recharge time?

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.

Can I choose red or green exit letters, and add arrow directions?

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.

What mounting configurations are supported?

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.

How does the unit handle harsh or marine environments?

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.

What’s the warranty and recommended maintenance?

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.
