In buildings with multiple spaces containing fixed seats, the classification of the Emergency system shall be based on the total number of seats in the building. The aisle lighting requirement shall be based on the number of seats in each space.
9 Where System III is required, a System I or II may be installed. Where System II is required, a System I may be installed.
10 It is impossible to list each specific type of use and therefore some of the classifications are general. If there is any doubt concerning a particular building or use, consult the authority having jurisdiction.
700.6 Illumination Required.
(A) General. In general, every portion of a building devoted to the use or accommodation of occupants, including all assembly rooms, all means of egress leading to the streets, open courts, corridors, stairways, exits, emergency exit stairways, or any other part of the building used by occupants, shall be well illuminated in accordance with requirements for general illumination.
(B) Emergency. In addition, there shall be emergency illumination as required by 700.11 to enable occupants to evacuate the building without difficulty upon failure of the general illumination system. The emergency illumination shall be available within the time required for the application but not to exceed 10 seconds.
The required emergency lighting and exit lighting systems shall be functional whenever the building is occupied.
Emergency lighting systems shall be designed and installed so that the failure of any individual lighting element, such as the burning out of a light bulb, cannot leave in total darkness any space that requires emergency illumination.
Exception: Except as allowed in 700.66(C)(6).
Where high-intensity discharge lighting such as high- and low-pressure sodium, mercury vapor, and metal halide is used as the sole source of normal illumination, the emergency lighting system shall be required to operate until normal illumination has been restored.
Exception No. 1: In residential buildings, emergency fixtures which illuminate areas of a building with unobstructed natural illumination shall be permitted to be controlled by photocell(s). The photocell shall be permitted to control multiple fixtures as long as the photocell and the fixtures are located in the area with the natural illumination insuring that the illumination required in 700.11 is present in the space at all times.
Exception No. 2: In buildings with not more than 12 dwelling units and not greater than 4 stories above grade, with open exterior means of egress, emergency illumination shall not be required on the exterior portion of the means of egress, where sufficient general illumination is present. Similar buildings with more than 12 dwelling units or greater than four stories above grade may only omit exterior emergency illumination with special permission.
(C) Source. All buildings requiring emergency illumination as stated in 700.5 shall not rely solely upon electric utility power as a source.
Such buildings shall have an emergency system as called for in Table 700.5. In addition, if the auxiliary source is one of the sources listed in 700.33(A) through (G), an additional on-site source of power for the emergency lighting and exit lighting systems shall be required.
