TIA 99-1 (Tentative Interim Ammendment) with an effective date
of May 22, 2000 states that the minimum required discharge from
each of the "design sprinklers" for systems designed to NFPA 13
must be calculated based on delivering a minimum design density
of 0.1 gpm/sq. ft. for each of the listed coverage areas shown in
Table 1, Table 2, Table 3, or Table 4. Consult the authority having
jurisdiction regarding the application of this TIA to the currently
adopted NFPA 13.
Model LF Residential Pendent and Recessed Pendent Sprinklers
must be installed using the obstruction criteria for extended
coverage sprinklers found in the current edition of NFPA 13.
NOTES
Residential Fire Sprinkler Systems should only be designed
and installed by those competent and completely familiar
with automatic sprinkler system design, installation
procedures, and techniques.
The sprinkler must be secured in position by firmly fastening
the sprinkler system piping to the structure. If the sprinkler is

not properly secured in position, reaction forces resulting
from sprinkler operation could alter its orientation and its
water distribution pattern. The sprinkler escutcheon cannot
be used to hold the sprinkler in position.
Several criteria may apply to the installation and usage of
each sprinkler. Consequently, it is recommended that the
sprinkler system designer review and develop a working
understanding of the complete list of criteria prior to initiating
the design of the sprinkler system.
Questions concerning sprinkler installation and usage
criteria, which are not covered by the following instructions,
should be submitted to Central Sprinkler. Include sketches
and technical details as appropriate.
In some instances, the requirements of this document may
concern specifications which are more stringent and which
take precedence over those specified in NFPA 13, NFPA 13D,
NFPA 13R, or by the authority having jurisdiction.
