TYCO, PENDANT FOAM BRONZE/BRASS WATER SPRINKLER (1/2" M.NPT)
Sprinkler Spec. Sheet
TYCO Model B-1 Upright and Pendent
Foam-Water Sprinklers are air-aspirating 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 sprinkler pattern is necessary as in the case
of NFPA 16, “Standard for the Installation of Foam-Water Sprinkler and
Foam-Water Spray Systems.”
TYCO 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 openings 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 predetermined discharge pattern, as well
as to discharge water similar to standard spray sprinklers. To meet the
intent of NFPA 16, foam-water sprinklers must be able to sufficiently distribute water after depletion of the foam
concentrate.
