APPROVALS AND STANDARDS
The Model TFP1 Residential Flush
Pendent Sprinklers are listed by Un-
derwriter’s Laboratories, Inc. (UL) and
by Underwriters Laboratories, Inc. for
use in Canada (C-UL) under the name
of Tyco Fire Products. With exception
to the sloped ceiling criteria, the ap-
provals only apply to the service con-
ditions indicated in the design Criteria
section.
WARNINGS
The Model TFP1 Residential
Flush Pendent Sprinklers de-
scribed herein must be installed
and maintained in compliance
with this document, as well as
with the applicable standards of
the National Fire Protection As-
sociation, in addition to the
standards of any other authori-
ties having jurisdiction. Failure
to do so may impair the integrity
of these devices.
Because of the above cited stipu-
lations and the varied nature of
residential type architecture,
there will be some compartment
designs which cannot be fully
sprinklered in accordance with
the recommendations of NFPA 13,
13D, or 13R. In the event of this
condition, consult the authorities
having jurisdiction for guidance
and approval.
It is the responsibility of the in-
stalling contractor to provide a
copy of this document to the
owner or his representative, and
in turn, it is the obligation of the
owner to provide a copy of this
document to a succeeding owner.
The owner is responsible for
maintaining their fire protection
system and devices in proper op-
erating condition. The installing
contractor or sprinkler manufac-
turer should be contacted relative
to any questions.

DESIGN CRITERIA
The Model TFP1 Residential Flush
Pendent Sprinklers must only be in-
stalled and utilized in accordance with
the following described criteria which
are provided by the manufacturer.
NOTES
Residential Fire Sprinkler Sys-
tems should only be designed and
installed by those competent and
completely familiar with auto-
matic sprinkler system design, in-
stallation procedures, and tech-
niques.
Several criteria may apply to the
installation and usage of each
sprinkler. Consequently, it is rec-
ommended that the sprinkler sys-
tem designer review and develop
a working understanding of the
complete list of criteria prior to
initiating the design of the sprin-
kler system.
Questions concerning sprinkler
installation and usage criteria
which are not covered by the fol-
lowing instructions should be
submitted to Tyco Fire Products
Include sketches and technical
details as appropriate.
In some instances, the require-
ments of this document may con-
cern specifications which are
more stringent and which take
precedence over those specified in
NFPA 13, NFPA 13D, NFPA 13R,
or by the authority having juris-
diction.
The spray from the sprinkler is
distributed radially outward and
downward from the sprinkler de-
flector. Consequently, the sprin-
klers must be located such that
there will not be any blind spaces
shielded from spray by partitions,
room dividers, overhangs or other
parts of the dwelling structure.
The number of sprinklers within
each compartment (as defined by
NFPA 13, 13D, or 13R), must be
kept as few as possible. Do NOT
use more sprinklers than neces-
sary to cover a particular space.
Use only the escutcheon provided
with the Model TFP1.
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, re-
action forces resulting from
sprinkler operation could alter
its orientation and its water dis-
tribution pattern. The sprinkler
escutcheon cannot be used to hold
the sprinkler in position.
General Service Conditions.
The
Model TFP1 must only be utilized in
wet pipe sprinkler systems.

TABLE A
NFPA 13D AND NFPA 13R HYDRAULIC DESIGN CRITERIA
(a) For coverage area dimensions less than or between those indicated, it is
necessary to use the minimum required flow for the next highest coverage area
for which hydraulic design criteria are stated.
(b) Requirement is based on minimum flow in GPM from each sprinkler. The
associated residual pressures are calculated using the nominal K-factor. Refer to
Hydraulic Design Criteria Section for details.
