2. In no case shall a control switch for emergency lighting in a theater or notion picture theater be placed in a motion picture projection booth of on a stage, except that where multiple switches are provided, one such switch may be installed in such location when so arranged that it can energize, but not disconnect, the circuit (see section 700-27).
700-46. Other Switches.
1. Exterior Lights. Those lights on the exterior of the building which are not required for illumination when there is sufficient daylight may be controlled by an automatic light-actuated device approved for the purpose (see section 700-27).
2. Existing Building Corridors. Switching arrangements to transfer corridor lighting in patient areas of health care occupancies from overhead fixtures to fixtures designed to provide night lighting may be permitted, provided the switching system is so designed that switches can only select between two sets of fixtures and cannot extinguish both sets at the same time (see section 700-27).
