General
Description
The TYCO Series TY-B, 5.6 K-fac-
tor, Conventional Sprinklers (TY365)
described in this data sheet are stan-
dard response -standard coverage,
decorative 5 mm glass bulb type
spray sprinklers. These sprinklers are
intended to be installed either pendent
or upright, and in either position, they
produce a spherical water discharge
pattern with approximately 50% of
the discharge directed upwards and
approximately 50% of the discharge
directed downwards.
Conventional sprinklers are generally
used with Ordinary and Extra High
Hazard Class Systems, as defined by
the automatic sprinkler system installa-
tion rules of the country and authority
having jurisdiction. The NFPA permits
the use of “Old Style Sprinklers” where
special construction features require a
unique water distribution; for the pro-
tection of fur vaults; or, the replace-
ment of similar sprinklers that had been
installed prior to 1955.

dition. Contact the installing contrac-

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.
