Tyco B-1 Manual

Model B-1 — 3.0 K-factor
Upright and Pendent
Foam-Water Sprinklers
General
Description
TYCO Model B-1 Upright and Pendent
Foam-Water Sprinklers are air-aspirat-
ing foam discharge outlets designed
for use in foam-water deluge systems.
They are designed for flammable 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 sprin-
kler pattern is necessary as in the case
of NFPA 16, "Standard for the Instal-
lation of Foam-Water Sprinkler and
Foam-Water Spray Systems."
It is recommended that the end user
be consulted with respect to the suit-
ability of the materials of construction
for any given corrosive environment.
The effects of ambient temperature,
concentration of chemicals, and gas/
chemical velocity, should be consid-
ered, at a minimum, along with the cor-
rosive nature 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 Sprinklers.
NOTICE
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
PROTECTION ASSOCIATION (NFPA),

regulatory and health information.
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
installation 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
TYCO Model B-1 Foam-Water Sprin-
klers are designed with a unique ven-
turi-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 stan-
dard spray sprinklers. To meet the
intent of NFPA 16, foam-water sprin-
klers must be able to sufficiently dis-
½ )
tribute water after depletion of the foam
concentrate.
