FAQs About NYC‑Approved Exit Signs
What makes an exit sign NYC approved?
NYC regulations require 8″ red letter EXIT signs with 1″ stroke, steel or aluminum housing, UL 924 listing, and 90-minute battery backup. Many also need weatherproof ratings.
Are metal housings required?
Yes—FDNY and NYC codes mandate sturdy steel or aluminum housings for durability in public buildings and high-rise structures.
Do they need battery backup?
Absolutely—UL 924 certified signs include Ni‑Cd or Li‑ion batteries that deliver 90 minutes of emergency illumination during outages.
Can they be used outside?
Yes—wet- or damp-location rated models (NEMA 4X or IP65+) are ideal for stairways, tunnels, building entrances, and transit facilities.
Is self-testing necessary?
Not mandatory, but self-test diagnostics are highly recommended to simplify NYC’s monthly and annual inspection requirements.
What mounting options are offered?
Most models support wall, ceiling, pendant, or recessed installations to meet the diverse mounting needs across NYC buildings.
Do they work with photoluminescent systems?
Yes—some signs are Local Law 26–compatible and integrate with photoluminescent path lighting systems for layered egress safety.
