The Hazardous Location Exit Sign HLWLEZU is a heavy-duty, safety-certified emergency lighting solution engineered for extreme and high-risk environments. Designed for industrial applications where flammable gases, vapors, or moisture may be present, this unit delivers maximum reliability, durability, and compliance in the most demanding conditions.

Constructed with a fiberglass-reinforced polycarbonate housing, the HLWLEZU offers exceptional impact resistance and corrosion protection. The UV-stabilized high-impact lens and integrated molded gasket system ensure long-lasting performance while maintaining a fully sealed enclosure with stainless steel hardware for enhanced durability.

This exit sign features ultra-bright, energy-efficient LED technology with field-selectable red or green illumination, ensuring clear visibility and code compliance across various facility requirements. The EZ snap-out chevron directional indicators allow quick configuration for directional guidance.

Engineered for hazardous environments, the HLWLEZU is rated for Class I, Division 2, Groups A, B, C & D, making it suitable for locations with potentially explosive atmospheres. It is also IP66 rated, providing superior protection against dust and powerful water jets, and is additionally UL listed for wet locations.

For emergency operation (EM models), the unit includes a 4.8V maintenance-free NiCd battery that provides a minimum of 90 minutes of emergency illumination. A solid-state transfer switch ensures immediate activation during power failure, while the automatic two-rate charger fully recharges the battery within 24 hours.

A bi-color LED indicator displays system status (green for normal operation, red for battery check), while a push-to-test switch enables quick compliance testing.

Installation is flexible and secure with a polycarbonate mounting canopy for top or end mounting, along with a gasketed universal knockout backplate designed for watertight wall installation. Conduit knockouts are also provided for sealed electrical entry.

This model is fully certified for demanding industrial safety requirements and complies with CEC Title 20 energy regulations, making it a reliable choice for hazardous environments requiring strict safety standards.
