Self Testing Exit Signs – Auto Diagnostic

Self Testing Exit Signs (also written self-testing exit signs) automate the code-required checks in NFPA 101 and OSHA. These UL 924–listed LED fixtures run monthly 30-second tests and an annual 90-minute discharge—no manual push-button testing or paper logs. For a one-fixture solution with lamps, see self testing exit sign & light combos; for wet-prone areas, browse wet-location exit signs.

What to Look for in Self Testing Exit Signs

  • Compliance & tests: UL 924 listed with automated monthly 30-second and annual 90-minute tests to satisfy NFPA 101/OSHA (confirm with your AHJ).
  • Scheduler & controls: Verify factory test schedule, ability to defer/override during business hours, and manual test initiation without opening the housing.
  • Status indicators: Front-panel LED shows clear pass/fail and distinct fault codes (AC, charger, battery, LED/board); visible from floor level for fast inspections.
  • Error memory: Unit should retain last test results/fault history after power loss to simplify documentation and audits.
  • Legend & visibility: Choose letter color (red/green), single/double-face, and ensure sightlines and viewing distance meet plan requirements (often up to ~100 ft).
  • Field arrows: Prefer field-selectable chevrons to align with actual egress direction and reduce SKUs across floors/zones.
  • Batteries: Maintenance-free Ni-Cd, NiMH, or lithium; check recharge time, ambient range, and expected service life; cold-weather options if needed.
  • Electrical safeguards: Universal 120/277 VAC, brownout protection, low-voltage disconnect, and surge suppression for reliability.
  • Damp/wet & durability: Specify damp/wet-location ratings where required; consider vandal-resistant metal or edge-lit housings for public areas.
  • Mounting & service: Universal wall/ceiling/end mounts; ensure accessible test switch and tool-less entry or quick-connect battery for faster maintenance.
  • Documentation: Keep a simple log of auto-test results/faults and corrective actions to stay inspection-ready.

Each unit includes a built-in self-diagnostic system that continuously monitors AC input, charger status, battery health, and lamp operation. A front-panel LED indicates test results and faults at a glance—keeping you inspection-ready with minimal maintenance effort.

Choose thermoplastic, aluminum, or edge-lit housings to match your interior. Most models provide universal wall/ceiling/end-mount hardware, field-selectable chevrons, and maintenance-free batteries (Ni-Cd, NiMH, or lithium) for the required 90-minute runtime during outages.

💡 What is a self testing exit sign? A UL 924–listed fixture with integrated electronics that automatically runs functional and full-discharge tests on schedule—helping you maintain NFPA 101 and OSHA compliance without manual inspections.

For humid or exterior-adjacent spaces, use damp-location exit signs. Need signage and egress lighting in one unit? Explore self testing exit sign & light combos.

Self Testing Exit Signs – Spec Guide

  • Compliance & tests: UL 924 listed with automated monthly 30-second and annual 90-minute tests; align with NFPA 101 (verify with AHJ).
  • Scheduler & controls: Confirm factory schedule, ability to defer/override during business hours, and manual test initiation without opening the housing.
  • Status & fault codes: Front-panel indicator should differentiate AC, charger, battery, and LED/board faults; visibility from floor level preferred for quick checks.
  • Error memory & logs: Device retains last test results/fault history after power loss; helpful for inspections and PM records at large sites.
  • Legend & visibility: Choose red/green letters, confirm viewing distance (often up to ~100 ft) and clear sightlines along approach paths in plan layouts.
  • Faces & arrows: Specify single or double-face; use field-selectable chevrons to match actual egress direction and reduce SKUs across floors/zones.
  • Mounting: Universal wall/ceiling/end hardware; verify projection and clearances near doors, sprinklers, and other signage; ensure test switch access after install.
  • Batteries: Maintenance-free Ni-Cd, NiMH, or lithium; check recharge time, ambient range, service life, and cold-weather package availability if needed.
  • Electrical safeguards: Universal 120/277 VAC, brownout protection, low-voltage disconnect, and surge suppression for reliability over time.
  • Damp/wet & durability: Select damp/wet-location ratings where required; consider vandal-resistant metal or edge-lit designs for public/high-traffic areas.
  • Serviceability: Favor tool-less entry or quick-connect batteries; indicators and push-to-test should be accessible without removing from the mount.

FAQs About Self-Testing Emergency Lights

What does “self-testing” mean?

Self-testing emergency lights automatically perform required NFPA tests—monthly 30-second checks and annual 90-minute discharge tests—without manual inspection.

How do I know if the light passes or fails a test?

Most self-testing units include LED indicators that display green (pass), red (fail), or flashing sequences to indicate issues with the battery, lamp, or charger.

Are these lights code compliant?

Yes. Self-testing models that meet UL 924 and NFPA 101 are fully compliant with OSHA and life safety code requirements.

Do I still need to record test results?

While self-testing automates the test process, many facilities still log indicator status during routine safety walkthroughs. Some advanced models offer remote monitoring or logs.

Can I use these outdoors or in wet areas?

Yes — as long as the fixture is wet-location rated or damp-location certified. These models are sealed and corrosion-resistant.

What types of buildings use self-testing units?

They're common in healthcare, retail, schools, and warehouses—anywhere emergency lighting is required and routine inspections are time-consuming.
