dear all i have aquestion below paragraphs
NFPA 13 (2010 edition)
8.15.4.4 Large Openings. Closely spaced sprinklers and draft
stops are not required around large openings such as those
found in shopping malls, atrium buildings, and similar structures where all adjoining levels and spaces are protected by
automatic sprinklers in accordance with this standard and
where the openings have all horizontal dimensions between
opposite edges of 20 ft (6 m) or greater and an area of 1000 ft2
(93 m2) or greater
NFPA (101)
3.3.28* Atrium. A large-volume space created by a floor open‐
ing or series of floor openings connecting two or more stories
that is covered at the top of the series of openings and is used
for purposes other than an enclosed stairway; an elevator hoist‐
way; an escalator opening; or as a utility shaft used for plumb‐
ing, electrical, air-conditioning, or communications facilities.
(SAF-FIR)
does it mean that opening which commnly used in malls as many floors share the same central opening does not require fire sprinklers ?
thanks in advance
