Series TY-FRB — 5.6 and 8.0 K-factor
Conventional (Old Style) Sprinklers
Quick Response
General
Description
The Series TY-FRB, 5.6 and 8.0 K-fac-
tor, Conventional Sprinklers described
in this data sheet are quick response -
standard coverage, decorative 3 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-
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and in-
stallation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

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 coatings for any given corro-
sive environment. The effects of ambi-
ent temperature, concentration of
chemicals, and gas/chemical velocity,
should be considered, as a minimum,
along with the corrosive nature of the
chemical to which the sprinklers will be
exposed.
WARNINGS
The Series TY-FRB Sprinklers de-
scribed herein must be installed and
maintained in compliance with this
document, as well as with the applica-
ble standards of the National Fire Pro-
tection Association, in addition to the
standards of any other authorities hav-
ing jurisdiction. Failure to do so may
impair the performance of these de-
vices.
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
with any questions.
