8.0 K-FACTOR MODEL FR-1 (SIN G8172) PENDENT AND (SIN G8153) UPRIGHT
GENERAL DESCRIPTION
The 8.0 K-Factor Model FR-1 Interme-
diate Level Sprinklers (Ref. Figure A)
are automatic sprinklers of the "quick
response" fusible solder type. They
are intended for use in fire sprinkler
systems designed in accordance with
the standard installation rules recog-
nized by the applicable Listing or Ap-
proval agency (e.g., UL Listing is
based on NFPA requirements). Both
the Pendent and Upright Sprinklers
produce a hemispherical water distri-
bution pattern below the deflector.
Intermediate Level Sprinklers are pri-
marily designed for use in rack storage
sprinkler systems, where their ther-
mally sensitive elements must be
shielded from the water spray of higher
elevation sprinklers which could oper-
ate earlier during a fire. Intermediate
Level Sprinklers are also used in appli-
cations such as beneath open gridded
catwalks.

TECHNICAL DATA
The 8.0 K-Factor Model FR-1 Interme-
diate Level Sprinklers are rated for use
at a maximum service pressure of 175
psi (12,1 bar) and they are available in
the temperature ratings and finishes
indicated in Table A.
The flow "Q" in GPM (LPM) is deter-
mined by the following formula:
Q
=
K p
where the nominal discharge coeffi-
cient "K" equals 8.0 (115,2) and "p"
equals the residual flowing pressure in
psi (bar).
The Model FR-1 Intermediate Level
Sprinklers are obtained by assembling
a 4-1/8 inch ( 104,8 mm) O.D. brass
Shield to the 8.0 K-Factor Model FR-1
Pendent or Upright Sprinklers de-
scribed in Technical Data Sheet
TD526. In the case of the pendent
sprinkler, field assembly of the shield
is required, and in the case of the up-
right sprinkler, the shield is factory as-
sembled to the sprinkler.
