Skip monthly manual pushes and annual stopwatches—self-diagnostic emergency lights run tests automatically and flag issues before inspections.
Last updated: October 2025
How self-testing works
Onboard controllers run periodic quick checks and a scheduled 90-minute annual discharge. They verify charger and transfer, confirm LED output, and log results automatically—then surface any faults on the status LED. New to emergency lighting overall? See the Emergency Lighting guide for UL 924 basics, testing rules, and selection tips.
Monthly & annual tests
- Monthly: a 30-second functional check runs on schedule (no clipboard run-around).
- Annual: a full 90-minute discharge validates runtime and transfer performance.
- Evidence: the unit stores pass/fail and often timestamped results for your log.
Status codes & logs
The status LED communicates pass/fail—and on many models, the likely cause (battery, charger, transfer). Keep a simple log and attach it to your inspection packet.
ROI & staffing
Automating the monthly and annual tests saves technician time, reduces missed checks, and keeps more units inspection-ready. For cost modeling, pair this page with the Self-Testing vs Manual ROI calculator.
FAQ
Do I still need any manual tests?
Verify local requirements; most teams still do quick visual rounds and keep logs, even with self-diagnostics.
Are self-testing lights UL 924 listed?
Yes—choose UL 924 listed models and install per the manufacturer’s instructions.
Do they support remote heads?
Many do. Confirm the base unit’s voltage (6V/12V) and watt budget for any remote heads.
