NYC Self‑Testing Exit Signs — Self‑Diagnostic Indicators, Runtime & Inspection

What “self‑testing” means (and what it doesn’t)

Self‑testing (a.k.a. self‑diagnostic) exit signs run scheduled checks, exercise the battery, and report status with indicator LEDs (and sometimes audible alerts). They don’t remove the requirement to be testable under UL 924—they automate it and make failures obvious, which speeds repairs and reduces manual rounds. For the national baseline that NYC builds on, see the Fire Code Guide: UL 924 Compliance Guide.

For NYC fundamentals (legend size/color, placement, runtime) start with the NYC Exit Sign Requirements (Pillar), then apply the testing and documentation notes here to align with NYC emergency lighting testing requirements.

NYC self‑testing exit signs requirements

• Legend & housing: NYC typically expects 8" red letters (1" stroke) and durable housings (often metal/architectural). Self‑diagnostics are an added capability, not a substitute for these fundamentals.
• Runtime & listing: UL 924 with 90‑minute emergency lighting operation; pass/fail states must be clear from the indicator logic.
• Arrows: Correct chevrons for the actual path (no field tape‑overs). This is a frequent inspection fail unrelated to the diagnostic feature.

Indicators & access (readability, service)

NYC reviewers stand at normal height and expect to read the indicator and reach the test interface without removing trims or canopies. Keep windows unobstructed; on recessed or architectural units, verify the trim does not cover the LED or test switch. If glare from glossy finishes hides the indicator, offset slightly or use diffusing lenses.

Self‑testing inspection checklist (NYC walk‑through)

1. Correct legend: 8" red “EXIT,” high contrast, arrows aligned to the path.
2. Construction & mounting: Tight trims; no sagging canopies; durable housings appropriate to the space.
3. UL 924 & runtime: Demonstrate the 90‑minute mode and show normal/charging/fault states.
4. Self‑diagnostics enabled: Confirm the periodic tests are active and provide the cut sheet with indicator code meanings.
5. Records: Bring a simple log (pass/fail/date/initials); note and close out faults before inspection.

Maintenance & logs (making self‑diagnostics count)

Self‑diagnostics automate monthly quick checks and the annual discharge, but you still keep the records. Standardize a one‑page log (device ID, location, pass/fail, note) and place a small QR label at each sign pointing to the shared sheet. Pair self‑testing with sensible spec choices so the indicator can be read and serviced quickly.

Where self‑diagnostic exit signs NYC help most

• Large portfolios: Automating tests reduces clip‑board time and surfaces faults early.
• Hard‑to‑access locations: Lifts or ceiling removals are expensive; self‑testing keeps routine checks quick.
• Harsh/wet areas: Use gasketed housings and sealed electronics; selection notes in the NYC wet‑location exit sign guide.

Combos, wet‑locations & recessed installs

If you need EXIT + heads on one unit above doors, compare the options in NYC exit sign + emergency light combos. For clean ceilings and corridors, ensure recessed trims don’t block indicators or test access—see recessed NYC exit signs & emergency lights for coordination tips.

FAQs

Does self‑testing replace manual testing in NYC?

No. It automates the checks and makes outcomes obvious; you still keep a simple log and correct faults promptly.

Are self‑diagnostic signs approved everywhere in NYC?

Yes—provided the unit is UL 924 listed, uses the required legend/color/housing, and diagnostics don’t block normal access or visibility.

Can I use self‑testing combos (EXIT + heads) above doors?

Yes—ensure the EXIT legend meets NYC building code exit signs expectations and the heads provide code‑required egress illumination.
