Frequently asked questions

Red or green letters: which does code require?

It depends on your jurisdiction. National model codes allow either color, but some cities and states require a specific one. Check with your local authority having jurisdiction (AHJ), or match the signs already in the building.

What is the difference between AC only, battery backup and 2-circuit?

Battery backup signs carry their own battery for 90 minutes of operation. AC-only signs have no battery and must be on an emergency-backed circuit. 2-circuit signs take a normal and an emergency feed. The NX-504-LED is 2-circuit.

Where can the NX-504-LED be installed?

It is damp-location listed. Use a Nora vandal-resistant enclosure where one is linked for wet locations.

What are the dimensions of the NX-504-LED?

Nora lists it at 12.125" × 1.75" × 8.75" (L × W × H), weighing 2.5 lb. The spec sheet linked above has the full drawing.
