Series TY-B — 5.6 and 8.0 K-factor
Conventional (Old Style) Sprinklers
Standard Response
General
Description
The Series TY-B, 5.6 and 8.0 K-factor,
Conventional Sprinklers described in
this data sheet are standard 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 down-
wards.
Conventional sprinklers are generally
used with Ordinary and Extra High
Hazard Class Systems, as defined by
the automatic sprinkler system instal-
lation 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.
Corrosion resistant coatings, where
applicable, are utilized to extend the
life of copper alloy sprinklers beyond
that which would otherwise be ob-
tained when exposed to corrosive at-
mospheres. Although corrosion resis-
tant coated sprinklers have passed the
standard corrosion tests of the appli-
cable approval agencies, the testing is
not representative of all possible cor-
rosive atmospheres. Consequently, it
is recommended that the end user be
consulted with respect to the suitability
of these corrosion resistant coatings
for any given corrosive environment.
The effects of ambient temperature,
concentration of chemicals, and
gas/chemical velocity, should be con-
sidered, as a minimum, along with the
corrosive nature of the chemical to
which the sprinklers will be exposed.

WARNINGS
The Series TY-B Sprinklers described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Protec-
tion Association, in addition to the
standards of any other authorities hav-
ing jurisdiction. Failure to do so may
impair the integrity of these devices.
The owner is responsible for maintain-
ing their fire protection system and de-
vices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.

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, which then allows the
sprinkler to activate and water to flow.
