regulatory and health information.
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER

General
Description
The TYCO Series TY-FRB 2.8, 4.2, 5.6,
and 8.0 K-factor Upright, Pendent,
and Recessed Pendent Sprinklers
described in herein are quick response,
standard coverage, decorative 3 mm
glass bulb-type spray sprinklers. They
are designed for use in light or ordinary
hazard, commercial occupancies such
as banks, hotels, and shopping malls.
The sprinkler, where applicable, is
intended for use in areas with a finished

ceiling. This recessed pendent sprin-
kler uses one of the following recessed
escutcheons:
• Two-piece Style 10 (1/2 in. NPT)
or Style 40 (3/4 in. NPT) Recessed
Escutcheon with 1/2 in. (12,7 mm) of
recessed adjustment or up to 3/4 in.
(19,1 mm) of total adjustment from
the flush pendent position.
• Two-piece Style 20 (1/2 in. NPT)
or Style 30 (3/4 in. NPT) Recessed
Escutcheon with 1/4 in. (6,4 mm) of
recessed adjustment or up to 1/2 in.
(12,7 mm) of total adjustment from
the flush pendent position.
The adjustment provided by the
recessed escutcheon reduces the
accuracy to which the fixed pipe drops
to the sprinklers must be cut.
Corrosion-resistant coatings, where
applicable, are utilized to extend the
life of copper alloy sprinklers beyond
what would be obtained when exposed
to corrosive atmospheres. Although
corrosion-resistant coated sprinklers
have passed the standard corrosion
tests of the applicable approval agen-
cies, the testing is not representative
of all possible corrosive atmospheres.
Consequently, it is recommended that
the end user be consulted with respect
to the suitability of these coatings for
any given corrosive environment. The
effects of ambient temperature, con-
centration of chemicals, and gas/
chemical velocity, should be consid-
ered, as a minimum, along with the cor-
rosive nature of the chemical to which
the sprinklers will be exposed.
An intermediate level version of the
Series TY-FRB Pendent Sprinklers
is detailed in technical data sheet
TFP356. Sprinkler guards are detailed
in technical data sheet TFP780.
