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.

Technical Data Approvals UL and ULC Listed Discharge outlets and foam concentrates are Listed for use together. Refer to the individual foam concentrate Listing for operating limitations and compatibility with the B-1 Foam-Water Sprinklers as provided in the UL Fire Protection Equipment Directory. The Model B-1 Upright and Pendent Foam-Water Sprinklers meet the requirements of: MIL-S-901C (for light-weight Grade A shock-proof equipment) MIL-H-24146.
