Operation
The glass bulb contains a fluid which
expands when exposed to heat. When
the rated temperature is reached, the
fluid expands sufficiently to shatter the
glass bulb, allowing the sprinkler to
activate and water to flow.
Design
Criteria
The TYCO Series TY-B and TY-FRB
Sprinklers are intended for fire protec-
tion systems designed in accordance
with the standard installation rules
recognized by the applicable Listing or
Approval agency - for example, the UL
Listing is based on the requirements
of NFPA 13. Only the Style 10 or 40
Recessed Escutcheon, as applicable,
is to be used for recessed installation.
