Buyers Guide Tips

What to Look for in Damp Location Exit Signs

  • Damp rating: Built for humidity/condensation; not intended for direct spray or wash-down.
  • Sealed construction: Gasketed housing, covered test switch, and moisture-resistant electronics.
  • Legend readability: Even LED illumination with high contrast; field-selectable red/green.
  • Faces & chevrons: Single or double face with field-selectable directional arrows.
  • UL 924 runtime: Integrated battery provides at least 90 minutes of egress visibility.
  • Mounting & power: Universal wall/ceiling/end mounts and dual-voltage 120/277 VAC.
  • Diagnostics: Self-testing option to automate monthly/annual checks.
  • Upgrade path: For direct spray/wash-down, move to wet-location or enclosure-rated units.

Featuring sealed, corrosion-resistant housings and gasketed lenses, damp-rated units maintain readability where standard indoor fixtures may degrade. All models include a 90-minute battery backup for code-compliant egress, with red or green legends and field-selectable chevrons for directional guidance. Many offer self-testing exit signs to automate monthly/annual checks and reduce maintenance.

Installation is flexible with universal brackets for wall, ceiling, or end-mount applications and dual-voltage 120/277 VAC inputs. For paired lighting in the same environment, see damp-location emergency lights or choose battery backup exit signs for general indoor use.

What does “damp-location rated” mean?
The sign is engineered for humid interiors or areas with light moisture/condensation—not for direct water spray or rain. For hose-down, snow, or driving rain, upgrade to wet-location exit signs or NEMA-rated enclosures.

FAQs About Damp Location Exit Signs

What is a damp location exit sign?

It’s a UL 924–listed EXIT sign designed for interiors with humidity or condensation—e.g., stairwells, locker rooms, and entry vestibules—without direct water spray.

How is a damp-location sign different from wet-location rated?

Damp-location signs resist moisture and humidity but aren’t intended for direct rain or hose-down. For exposure to spray or weather, use wet-location exit signs or consider NEMA-rated exit signs.

Are damp-rated exit signs code compliant?

Yes—when UL 924 certified and installed per NFPA 101 and local AHJ requirements, they’re compliant for marked egress in damp areas.

Do they include battery backup?

Yes. Damp-rated EXIT signs provide at least 90 minutes of emergency illumination. For more options, see battery backup exit signs.

Can I install them in covered outdoor locations?

Yes, if protected from direct rain or spray. Covered breezeways, parking decks, and semi-enclosed walkways are typical damp-location applications.

Are self-testing models available?

Absolutely. Many self-testing exit signs are damp-rated and automate monthly/annual diagnostics for easier compliance.

What legend colors and faces can I choose?

Most models offer red or green LED legends, single- or double-face configurations, and field-selectable chevrons for direction.

What if the space needs wash-down or harsher protection?

Step up to wet-location exit signs or NEMA-rated exit signs to get the enclosure ratings required for spray, snow, or frequent cleaning.
