INTERMEDIATE LEVEL SPRINKLERS
MODEL F917
STANDARD RESPONSE, SOLDER TYPE, 8.0 K-FACTOR, 3/4" NPT**
GENERAL DESCRIPTION
The 8.0 K-Factor Model F917 Interme-
diate Level Sprinklers (Ref. Figure A)
are automatic sprinklers of the “stand-
ard response” fusible solder type.
They are intended for use in fire sprin-
kler systems designed in accordance
with the standard installation rules rec-
ognized by the applicable Listing or
Approval 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.

The 8.0 K-Factor Model F917 Inter-
mediate Level Sprinklers described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as applicable standards

TECHNICAL DATA
The 8.0 K-Factor Model F917 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:
where the nominal discharge coeffi-
cient “K” equals 8.0 (115,2) and “p”
equals the residual flowing pressure in
psi (bar).
The Model F917 Intermediate Level
Sprinklers are obtained by assembling
a 3 inch ( 76,2 mm) O.D. brass Shield
to the 8.0 K-Factor Model F916 Pen-
dent or Upright Sprinklers described in
Technical Data Sheet TD527H. In the
case of the pendent sprinkler, field as-
sembly of the shield is required, and in
the case of the upright sprinkler, the
shield is factory assembled to the
sprinkler.
