Intent 1:

To exempt certain conductors from the requirements of Sentence, on the basis that:

  • emergency lighting units within the same storey need not operate for extended periods of time as it is assumed that occupants will rapidly vacate the floor of fire origin, and
  • it is assumed that a fire within the same storey will render emergency lighting units inoperative as they are not tested nor designed to operate continually under fire conditions.
