Emergency & Exit Lighting Standards Flashcards

Under NFPA 101, what is the minimum illumination level required at the floor along the path of egress during emergency lighting operation?

Answer: 1.0 foot-candle

NFPA 101 requires a minimum of 1.0 foot-candle (10.8 lux) at the floor level along the egress path.

What is the maximum uniformity ratio (maximum to minimum illuminance) permitted along an egress path under NFPA 101?

Answer: 40:1

NFPA 101 allows a maximum uniformity ratio of 40:1 (maximum to minimum) along egress paths.

Which IES standard specifically addresses emergency and exit lighting design recommendations?

Answer: IES RP-29

IES RP-29 provides recommended practices specifically for lighting for egress and emergency situations.

A remote self-contained emergency luminaire uses an internal battery. What does 'self-contained' specifically refer to?

Answer: The battery, charger, and lamp are all within the same housing

A self-contained unit integrates the battery, charger, and lamp all within a single housing.

In a central battery emergency lighting system, what device typically monitors the health of each individual luminaire?

Answer: An addressable monitoring module

Addressable monitoring modules in central battery systems track the status of each connected luminaire for fault detection.

Exit signs using LED light sources compared to incandescent exit signs primarily offer what advantage?

Answer: Significantly longer lamp life and lower energy consumption

LED exit signs consume far less energy and have much longer service life than incandescent versions.

When an exit sign is located at a door, where must the sign be positioned relative to the door according to NFPA 101?

Answer: Centered above the door opening

NFPA 101 requires exit signs at doors to be placed directly above or adjacent to the door in the path of egress travel.
