translated to:
NFPA 13R does not require the breezeway to be protected and the IBC
does not impose additional requirements (since a breezeway is not a
rare feature and it is NOT a balcony, deck or patio).

13R-19 Log #19 AUT-RSS Final Action: Accept in Principle
(6.9.5)
Submitter: Phillip A. Brown, American Fire Sprinkler Association, Inc.
Comment on Proposal No: 13R-44
Recommendation: Add new text to read as follows:
A.6.9.5 An example of an open corridor or breezeway is one that
empties to
an outside stairway and has no doors attached to it. Another example
is an
exterior wraparound corridor that is typical in a two- to three-
story motel.
Substantiation: Guidance is needed to help explain what the word
"open"
means as used in 6.9.5. The comment found in the Handbook helps
explain
what "open" means and should be brought forward into the annex.
Committee Meeting Action: Accept in Principle
Revise proposal to read as follows:
A.6.9.5 An example of an open corridor or breezeway is one that is
exposed
to
the outside atmosphere (temperature) and empties to an unenclosed
stairway
and has no doors attached to it. Another example is an exterior
wraparound
corridor that is typical in a two- to three-story motel.
Committee Statement: Further clarifies the intent of the committee
and the
standard in defining an open corridor.
Number Eligible to Vote: 25
Ballot Results: Affirmative: 23 Negative: 1
Ballot Not Returned: 1 Schirmer, C.
Explanation of Negative:
HAAGENSEN, D.: In the Northeast, there are many situations where a
porch/
balcony may be almost entirely enclosed except for some small screened
windows, thereby creating a space where heated fire gases during a
fire will
build up and not allow for tenability in the space. The guidance
given in
the
new Annex will suggest that such a space is "open".
2009 IBC/IRC
[F] 903.3.1.2.1 Balconies and decks. Sprinkler protection shall be
provided
for exterior balconies, decks and ground floor patios of dwelling
units
where the
building is of Type V construction, provided there is a roof or deck
above.
Sidewall sprinklers that are used to protect such areas shall be
permitted
to be located such that their deflectors are within 1 inch (25 mm)
to 6
inches (152 mm) below the structural members and a maximum distance
of 14
inches (356 mm) below the deck of the exterior balconies and decks
that are
constructed of open wood joist construction.
102.1 General. Where there is a conflict between a general
requirement and a
specific requirement, the specific requirement shall be applicable.
Where,
in any specific case, different sections of this code specify
different
materials, methods of construction or other requirements, the most
restrictive shall govern.
102.4 Referenced codes and standards. The codes and standards
referenced in
this code shall be considered part of the requirements of this code
to the
prescribed extent of each such reference. Where differences occur
between
provisions of this code and referenced codes and standards, the
provisions
of this code shall apply.
104.1 General. The building official is hereby authorized and
directed to
enforce the provisions of this code. The building official shall
have the
authority to render interpretations of this code and to adopt
policies and
procedures in order to clarify the application of its provisions. Such
interpretations, policies and procedures shall be in compliance with
the
intent and purpose of this code. Such policies and procedures shall
not have
the effect of waiving requirements specifically provided for in this
code.
Hope this helps,
