Wet Location Exit Signs

Wet location exit signs are engineered to perform in environments exposed to rain, high humidity, and direct water spray. Also called weatherproof exit signs or outdoor exit signs, these fully sealed fixtures maintain visibility and code compliance in the harshest conditions. Watertight gaskets and corrosion-resistant housings protect internal components from moisture, dust, and impact—ensuring uninterrupted operation and long-term reliability.

UL 924 Listed IP66 or NEMA 4X LED Illumination 90-Min Battery Backup

All wet location exit signs are UL 924 compliant and meet NFPA 101 and OSHA life safety codes. They deliver a minimum of 90 minutes of emergency lighting during power outages. Housing materials range from thermoplastic to die-cast aluminum and fiberglass—resistant to impact, UV exposure, and water intrusion.

Models are available with tamper-resistant fasteners, universal mounting kits (ceiling, wall, or end), and field-selectable chevrons. For added convenience, consider options with self-testing diagnostics to automate monthly and annual test cycles.

Common use cases include parking garages, loading docks, food prep areas, car washes, outdoor stair towers, and mechanical rooms. If your installation area is continuously exposed to moisture, these outdoor-rated exit signs ensure code compliance and long-term performance.

💡 What is a wet location exit sign?
A wet location exit sign is a sealed, weather-resistant fixture certified to NEMA 4X or IP66 standards. It’s designed to operate safely in environments with rain, hose-downs, condensation, and high humidity.

Wet Location Exit Signs – Spec Guide

  • Ingress protection: Require IP66 or NEMA 4X for direct rain, hose-down, and spray; gasketed enclosure, sealed conduit entries, and corrosion-resistant hardware.
  • Egress compliance & runtime: UL 924 listed with verified 90-minute emergency operation; coordinate illuminance/spacing with NFPA 101 (per AHJ).
  • Legend visibility: Uniform LED illumination (red/green); confirm character height and viewing distance (e.g., 6″ letters commonly specified to ~100 ft, model-dependent).
  • Faces & chevrons: Single/double-face configurations with field-selectable chevrons set on site to match actual egress direction and reduce SKU count.
  • Materials & durability: Thermoplastic, fiberglass (FRP), or powder-coated aluminum; UV stabilization, impact-resistant lens, stainless fasteners for coastal/industrial exposure.
  • Temperature range: Verify min/max ambient; specify cold-weather heater kits for freezer docks/winter climates and high-temp options near boilers/mechanical rooms.
  • Power & safeguards: Dual 120/277 VAC input, solid-state charger, automatic transfer, brownout protection, low-voltage disconnect, surge suppression.
  • Battery chemistry: Maintenance-free Ni-Cd or lithium sized for ambient/recharge time; document expected service life and PM intervals.
  • Diagnostics: Self-testing availability for automated monthly 30-sec and annual 90-min tests with floor-visible status/fault indication to speed inspections.
  • Mounting & sealing: Universal wall/ceiling/end hardware; verify canopy projection, gasket compression, drip-edge orientation, weep-hole placement, and conduit sealing during install.

FAQs About Wet Location Exit Signs

What is a wet location exit sign?

It's an exit sign designed to operate in outdoor or hose-down environments where direct water exposure is expected. These fixtures are UL 924 listed and sealed against moisture ingress for reliable emergency lighting in wet conditions.

Where are wet-location rated exit signs required?

They’re required in outdoor stairwells, parking garages, commercial kitchens, food prep areas, and other spaces exposed to rain, splashing, or wash-down procedures.

How are they different from damp location signs?

Wet-location exit signs are rated for direct water contact, while damp-location signs are limited to indirect moisture or humidity. Always verify the IP66 or NEMA 4X rating before selecting a fixture for your environment.

Do they include battery backup?

Yes. All models feature a sealed internal battery that provides at least 90 minutes of runtime during outages. View our full battery backup exit signs collection for related products.

Are self-testing models available?

Many self-testing exit signs are rated for wet locations and automate code-required testing—saving time on monthly and annual inspections.

Can they withstand extreme temperatures?

Yes. Select models are built for hot, cold, or freezing outdoor conditions. Look for wide operating temperature ranges and optional internal heaters for cold-weather use.
