Buyers Guide Tips

What to Look for in Damp-Location Exit Sign Combos

  • Damp rating: Certified for humidity/condensation; not intended for direct spray or wash-down.
  • Sealed construction: Gasketed housing, covered test switch, and moisture-resistant electronics.
  • UL 924 runtime: Verified 90-minute operation with compliant egress illumination.
  • Legend & faces: Even LED legend, field-selectable chevrons, single/double-face options.
  • Lamp heads & optics: Adjustable heads sized for corridor spacing and coverage needs.
  • Power & charging: Dual 120/277 VAC input with solid-state charger and automatic transfer.
  • Diagnostics: Availability of self-testing to automate monthly/annual checks.
What does “damp-location rated” mean?
The fixture is designed to operate safely in environments with humidity or light moisture/condensation but not direct water spray. For direct exposure or wash-down, choose wet-location exit sign and emergency light combos or NEMA-rated enclosures.

Common applications include stairwells, vestibules, locker rooms, and covered outdoor corridors—areas where standard fixtures can fail from moisture exposure. Each combo provides a minimum of 90 minutes of emergency illumination to maintain code-compliant egress during a power outage.

Features typically include universal mounting brackets for wall, ceiling, or end-mount installations, field-selectable chevrons, push-to-test switches, charge/status indicators, and optional self-testing diagnostics to automate monthly and annual checks. Sealed housings and gasketed lenses help resist moisture ingress for long-term reliability.

FAQs About Damp Location Exit Sign & Light Combos

What qualifies as a “damp location”?

An area exposed to humidity, condensation, or occasional moisture but not direct water spray or wash-down—e.g., stairwells, vestibules, locker rooms, and covered outdoor corridors.

Are these combos code compliant?

Yes. Damp-rated combos are UL 924 listed and support NFPA 101 life-safety requirements, providing a minimum 90 minutes of emergency illumination.

Can I use them outdoors?

Only in covered locations without direct rain or hose spray. For direct exposure or wash-down, specify wet-location or NEMA/IP-rated units instead.

Do they include battery backup?

Yes. Maintenance-free batteries (Ni-Cd or lithium, model dependent) power both the EXIT legend and lamp heads for at least 90 minutes during outages.

Are self-testing models available?

Many versions offer self-diagnostics that automate the required monthly 30-second and annual 90-minute tests and indicate faults via a status LED.

What mounting options do they support?

Universal hardware typically supports wall, ceiling, or end-mount installations; field-selectable chevrons simplify directional wayfinding.

What about legend colors and faces?

Most models offer red or green LED legends and single- or double-face configurations; verify local preferences with your AHJ if needed.
