Model B-1 — 3.0 K-factor
Upright and Pendent
Foam-Water Sprinklers
General
Description
The Model B-1 Upright and Pendent
Foam-Water Sprinklers are air-aspi-
rating foam discharge outlets de-
signed for use in foam-water deluge
systems. They are designed for flam-
mable liquid risks where it is desired to
apply foam from overhead sprinklers
(either upright or pendent) and where
follow-up with plain water in a standard
spray sprinkler pattern is necessary as
in the case of NFPA 16, "Standard for
the Installation of Foam-Water Sprin-
kler and Foam-Water Spray Systems".
It is recommended that the end user be
consulted with respect to the suitability
of the materials of construction for any
given corrosive environment. The ef-
fects of ambient temperature, concen-
tration of chemicals, and gas/chemical
velocity, should be considered, at a
minimum, along with the corrosive na-
ture to which the sprinklers may be
exposed.
The Model B-1 Foam-Water Sprinkler
is a redesignation for the Gem Issue
B-1 and Star Model B-1.
WARNINGS
The Model B-1 Foam-Water Sprinklers
described herein must be installed and
maintained in compliance with this
document, as well as with the applica-
ble standards of the National Fire Pro-
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and in-
stallation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

Operation
The Model B-1 Foam-Water Sprinklers
are designed with a unique venturi
style body. As foam solution (water
and foam concentrate mixture) flows
through the inlet of the body, air is
drawn into the body through the open-
ings adjacent to the wrenching area.
The foam solution and air mix is then
agitated to create an air-aspirated
foam.
The B-1 Foam-Water Sprinklers are
designed to discharge foam in a pre-
determined discharge pattern, as well
as to discharge water similar to stand-
ard spray sprinklers. To meet the in-
tent of NFPA 16, foam-water sprin-
klers must be able to sufficiently

distribute water after depletion of the
foam concentrate.
