2702.1.9 Unit Battery Systems

AMENDMENT
This section has been amended at the state or city level.
Unit storage battery systems shall be installed in accordance with this Chapter and these regulations. Where such systems utilize spotlight type of distribution, the projected light shall be directed toward means of egress doorways. Units shall be located to distribute light over the entire floor area, reducing glare and sharp shadows to a minimum.
