Residential
Flush Pendent Sprinklers
Model TFP1, K=4.2
GENERAL DESCRIPTION
The Model TFP1 Residential Flush Pendent Sprinklers
are decorative fusible solder sprinklers designed for use
in residential occupancies such as homes, apartments,
dormitories, and hotels. When aesthetics is the major con-
sideration, the Model TFP1 should be your first choice.
They are to be used in wet pipe residential sprinkler sys-
tems for one- and two-family dwellings and mobile homes
per NFPA 13D; wet pipe residential sprinkler systems for
residential occupancies up to and including four stories in
height per NFPA 13R; or, wet pipe sprinkler systems for
the residential portions of any occupancy per NFPA 13.
The Model TFP1 has a 4.2 (60,5) K-factor which provides
very low design flow rates at reduced residual pressures,
enabling smaller pipe sizes and water supply require-
ments.
The flush design of the Model TFP1 features a separable
escutcheon providing 3/8 inch (9,5 mm) vertical adjust-
ment. This adjustment reduces the accuracy to which the
fixed pipe drops to the sprinklers must be cut to help as-
sure a perfect fit installation.
The Model TFP1 has been designed with heat sensitivity
and water distribution characteristics proven to help in
the control of residential fires to improve the chance for
occupants to escape or be evacuated. However, residen-
tial fire sprinkler systems are not a substitute for intelli-
gent fire safety awareness or fire safety construction re-
quired by building codes.
WARNINGS
The Model TFP1 Residential Flush Pendent Sprinklers
described herein must be installed and maintained in
compliance with this document, as well as with the
applicable standards of the National Fire Protection
Association, in addition to the standards of any other
authorities having jurisdiction. Failure to do so may
impair the integrity of these devices.
Because of the above cited stipulations and the var-
ied 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 condi-
tion, consult the authorities having jurisdiction for
guidance and approval.
It is the responsibility of the installing 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 suc-
ceeding owner.
The owner is responsible for maintaining their fire
protection system and devices in proper operating
condition. The installing contractor or sprinkler manu-
facturer should be contacted relative to any ques-
tions.
OPERATION
The sprinkler assembly contains a small fusible solder
element. When exposed to sufficient heat from a fire, the
solder melts and enables the internal components of the
sprinkler to fall away. At this point the sprinkler activates
with the deflector dropping into its operated position (Ref-
erence Figure 1C), permitting water to flow.
