NEMA Rated Exit Sign & Emergency Light Combos – Waterproof, Sealed, Industrial-Grade

NEMA-rated exit sign and emergency light combos combine an illuminated EXIT legend with integrated LED lamp heads inside a fully sealed enclosure. Built for industrial wash-down zones, chemical storage, food processing areas, and outdoor utility spaces, these fixtures protect against water, dust, corrosion, and physical abuse while remaining UL 924 listed for code-compliant egress lighting.

Buyers Guide Tips

What to Look for in NEMA Rated Exit Sign & Emergency Light Combos

  • NEMA type & use: Match 4X (wash-down/corrosion), 12 (dust/drips), or 3R (rain/ice) to site conditions and cleaning practices.
  • Compliance & runtime: UL 924 listing with a minimum 90-minute operation; align with NFPA 101/OSHA and your AHJ.
  • Enclosure & sealing: Gasketed, fully sealed housing with continuous gaskets, tight fasteners, and sealed conduit hubs for hose/spray exposure.
  • Materials & corrosion: Fiberglass/polycarbonate or coated metal with stainless hardware for chemicals, cleaners, and salt-mist resistance.
  • Legend & faces: Standard 6 in letters (red/green) with typical viewing up to 100 ft; choose single or double-face as required by approach directions.
  • Directional chevrons: Prefer field-selectable arrows to match egress paths and reduce SKU complexity across layouts/facilities.
  • Lamp heads & optics: Adjustable LED (or MR16 on select models); size output/beam to achieve ≈ ≥1 fc average and ≥0.1 fc minimum at 90 minutes along paths of egress.
  • Power & electronics: Universal 120/277 VAC, solid-state charger/automatic transfer, low-voltage disconnect, status indicator, and test switch; brownout/surge protection recommended.
  • Battery & ambient: Maintenance-free Ni-Cd or lithium with 90-minute runtime; verify recharge time and ambient range; add heaters for cold rooms if needed.
  • Mounting & entries: Wall/ceiling/end mounting with sealed hubs; confirm hub size, J-box pattern, projection, and clearances near doors/equipment and traffic lanes.
  • Impact & durability: Impact-rated lenses/windows; consider guards in forklift/cart areas and verify UV/chemical resistance where applicable.
  • Diagnostics & upkeep: Self-testing electronics to automate monthly/annual checks and simplify inspection recordkeeping.

Housings are molded from sealed polycarbonate, fiberglass-reinforced composites, or powder-coated steel with gasketed seams and corrosion-resistant hardware. Internal battery systems (Ni-Cd or lithium-ion) supply at least 90 minutes of power to the EXIT legend and heads during an outage, helping meet NFPA 101 and OSHA life-safety requirements. Many models add self-testing exit sign combos for automated diagnostics.

Typical specs include dual-voltage 120/277 VAC, adjustable LED heads, field-selectable chevrons, and optional high-output optics (including MR16 on select models). For environments with persistent moisture, compare wet-location exit sign combos and damp-location exit sign combos.

💡 What is a NEMA-rated combo unit?
A sealed exit sign & emergency light combo with a NEMA enclosure (e.g., 4X/12) that guards against water, dust, corrosion, and impact—ideal for sanitary, industrial, and outdoor sites.

NEMA Rated Exit Sign & Emergency Light Combos – Spec Guide

  • NEMA type & application: Match 4X (wash-down/corrosion), 12 (dust/drips), or 3R (rain/ice) to sanitation, spray, and outdoor conditions on site.
  • Compliance & runtime: UL 924 listing; battery system provides a minimum 90-minute operation and aligns with NFPA 101/OSHA (verify with your AHJ).
  • Enclosure & sealing: Gasketed, fully sealed housings with continuous gaskets, tight fasteners, and sealed conduit hubs for hose/spray exposure; protected vents/drains if specified by the manufacturer.
  • Materials & corrosion: Fiberglass/polycarbonate or coated metal plus stainless hardware to resist chemicals, cleaners, and salt-mist environments.
  • Legend spec & faces: Standard 6-in letters with typical viewing up to 100 ft; choose red/green and single/double-face per approach directions and contrast needs.
  • Chevrons & configuration: Field-selectable arrows to align with egress paths and reduce SKU complexity across layouts/facilities.
  • Lamp heads & photometrics: Adjustable LED (or MR16 on select models); design to achieve ≈ ≥1 fc average and ≥0.1 fc minimum along egress paths for 90 minutes.
  • Power & electronics: Universal 120/277 VAC, solid-state charger/automatic transfer, low-voltage disconnect, Status LED, and test switch; brownout/surge protection recommended for industrial sites.
  • Battery & ambient: Maintenance-free Ni-Cd or lithium packs delivering ≥90 min runtime; verify recharge time and ambient temperature range; add heaters for cold rooms if required.
  • Mounting & entries: Wall/ceiling/end mounting with sealed hubs; confirm hub size/locations, J-box pattern, projection, and clearances near doors/equipment and traffic lanes.
  • Impact & durability: Impact-rated lenses/windows; consider guards in forklift/cart areas; ensure UV/chemical resistance where applicable.
  • Nameplate & markings: Label should list NEMA rating, UL file, input voltage, ambient range, and any special conditions of use for inspection readiness.

Frequently Asked Questions

What does a NEMA 4X or NEMA 12 rating mean?

NEMA 4X and NEMA 12 indicate the enclosure is sealed against dust, water spray, and moisture. NEMA 4X also adds corrosion protection for outdoor or washdown use, while NEMA 12 is intended for indoor industrial areas with non-corrosive liquids or airborne contaminants.

Can these combo units be used outdoors?

Yes. NEMA 4X–rated exit sign combos are built for outdoor and wet environments, including hose-down zones, rain exposure, and humid conditions.

Are the LED light heads adjustable?

Most models include fully adjustable LED or MR16 lamp heads so you can aim light along hallways, corridors, and stairwells for better coverage.

How do I know if my combo unit is functioning properly?

Units with self-testing diagnostics automatically run monthly and annual checks. A status LED signals normal operation or alerts you to battery/lamp issues.

Where are NEMA-rated combos typically installed?

They’re ideal for food processing plants, wastewater facilities, industrial washdown rooms, outdoor exits, and chemical storage areas—anywhere standard fixtures would degrade or fail.
