Design
Criteria
The TYCO Model TFP PH5, 5.6 K-fac-
tor (SIN TY3390) Institutional Horizon-
tal Sidewall Sprinklers are intended for
use in fire protection systems designed
in accordance with the standard instal-
lation rules recognized by the appli-
cable Listing or Approval agency (for
example, UL Listing is based on NFPA
13 requirements).
NOTICE
The Sprinkler Body must not extend
beyond the Institutional Escutcheon
(Ref. Figure 4). Otherwise, the tamper-
resistant design of the Model TFP PH5
will be compromised. Consequently,
Model 1752 Spacers, which are associ-
ated with other TFP institutional sprin-
klers, cannot to be utilized.
Integrity of the tamper-resistant design
of the Institutional Escutcheon is
dependent on the piping installation
design. When installed properly, the
Institutional Escutcheon is held fast to
the mounting surface by the tighten-
ing of the sprinkler assembly into the
sprinkler fitting. In order to accomplish
a proper installation, the sprinkler fitting
must be:
• properly located with respect to dis-
tance from the face of the sprinkler
fitting to the face of the mounting
surface (Ref. Figure 3);
• rigidly secured and held immobile;
and,
• installed with the center-line of the
sprinkler fitting perpendicular to the
mounting surface to assure that the
escutcheon sits squarely against
the mounting surface around the
entire perimeter of the Institutional
Escutcheon.
Figure 3 illustrates a typical installa-
tion that can be utilized to help adjust
the location of the sprinkler fitting; to
help assure immobility of the sprinkler
fitting; and, to help maintain perpen-
dicularity of the sprinkler fitting to the
mounting surface.
Installation
The TYCO Model TFP PH5 Sprinklers
must be installed in accordance with
this section.
NOTICE
R
efer to the Design Criteria section for
important information regarding the
piping installation design and its effect
on maintaining the integrity of the tam-
per-resistant design of the Institutional
Escutcheons.
Obtain a leak-tight 1/2 in. NPT sprin-
kler joint by applying a minimum-to-
maximum torque of 7 to 14 lb-ft (9,5
to 19,0 N
∙
m). Higher levels of torque
can distort the sprinkler inlet with con-
sequent leakage or impairment of the
sprinkler.
Do not attempt to compensate for
im proper location of the sprinkler fitting
by under- or over-tightening the sprin-
kler. Re-adjust the position of the sprin-
kler fitting to suit.
The Model TFP PH5 (SIN TY3390) must
be installed with a deflector-to-ceiling
distance of 4 in. to 6 in. (100 mm to
152,4 mm). To meet this requirement,
the center-line of the sprinkler water-
way must be located 4-1/2 in. to
6-1/2 in. (114,3 mm to 165,1 mm) below
the ceiling (Ref. Figure 3).
Only the Institutional Escutcheons
shown in Figure 2 can be utilized with
the Model TFP PH5.
