Requirements for Exit Sign Illumination
NFPA 101 defines the methods of illumination for exit signs:
Externally illuminated - the light source is contained outside of the device or legend that is to be illuminated. The light source is typically a dedicated incandescent or fluorescent source;
Internally illuminated - the light source is contained inside the device or legend that is illuminated. The light source is typically incandescent, fluorescent, electro luminescent, light-emitting diodes, or photoluminescent;
Photoluminescent Exit Sing - the sign is illuminated by self-contained power sources and operates independently of external power sources. (Batteries do not qualify as a self-contained power source.)
Photoluminescent Exit Sign - The face of the photoluminescent exit sign sign must be continually illuminated while the building is occupied. The face of the photoluminescent exit sign shall be illuminated according to its listing from the face of the sign. The illumination has to be a reliable source as determined by the Authority Having Jurisdiction, AHJ. The AHJ is the ultimate arbiter concerning safety practices and safety equipment for a particular locality. The charging light must be of the same type that is specified on the sign.
Photoluminescent Exit Signs need a specific type of light and a minimum level of light on the face to assure that the sign will be able to provide adequate illumination in an emergency situation. During illumination the sign shall not be connected to an automatic timer.
