Description
Model B-1 Upright and Pendent Foam-Water Sprinklers are ait-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.” 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 effects of ambient temperature, concentration of chemicals, and gas/ chemical velocity, should be
considered, at a minimum, along with the corrosive nature to which the sprinklers may be exposed. The Model B-1 Foam-Water
Sprinkler is a re designation for the Gem Issue B-1 and Star Model B-1 Sprinklers
