General
Description

The TYCO Series TY-FRB, 5.6 and

8.0 K-factor, Conventional Sprinklers
described in this technical 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,
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 instal­lation rules of the country and author­ity having jurisdiction. The National Fire
Protection Association (NFPA) permits
the use of “Old Style Sprinklers” where
special construction features require a
unique water distribution, for the pro­tection of fur vaults, or to replace 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 obtained
when exposed to corrosive atmo­spheres. Although corrosion-resistant
coated sprinklers have passed the
standard corrosion tests of the appli­cable Approval agencies, the testing is
not representative of all possible cor­rosive atmospheres. Consequently,

IMPORTANT

Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal­lation of sprinkler systems and com­ponents. Improper handling and
installation can permanently damage
a sprinkler system or its compo­nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

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, 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.

NOTICE

The TYCO Series TY-FRB Sprinklers
described herein must be installed
and maintained in compliance with this
document, as well as with the applica­ble standards of the NFPA, in addition
to the standards of any other authori­ties having jurisdiction. Failure to do so
may impair the performance of these
devices.

The owner is responsible for main­taining their fire protection system
and devices in proper operating con­dition. Contact the installing contrac­tor or product manufacturer with 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, allowing the sprinkler to
activate and water to flow.

Design
Criteria

The TYCO Series TY-FRB Conventional
Sprinklers are intended for fire protec­tion systems designed in accordance
with the standard installation rules
recognized by the applicable Listing
or Approval agency (e.g., UL Listing is
based on NFPA 13 requirements). The
Series TY-FRB Conventional Sprinklers
are only for non-recessed applications.

QUICK RESPONSE CONVENTIONAL SPRINKLERS

Installation

The Series TY-FRB Sprinklers must
be installed in accordance with this
section.

General Instructions

Do not install any bulb type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin­kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1/16 inch
(1,6 mm) for the 135°F (57°C) to 3/32
inch (2,4 mm) for the 286°F (141°C)
temperature ratings.

A leak-tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7 to
14 ft.-lbs. (9,5 to 19,0 Nm). A maximum
of 21 ft.-lbs. (28,5 Nm) of torque may be
used to install sprinklers with 1/2 NPT
connections. A leak-tight 3/4 inch NPT
sprinkler joint should be obtained with
a torque of 10 to 20 ft.-lbs. (13,4 to 26,8
Nm). A maximum of 30 ft.-lbs. (40,7
Nm) of torque is to be used to install
sprinklers with 3/4 NPT connections.
Higher levels of torque may distort the
sprinkler inlet and cause leakage or
impairment of the sprinkler.

Step 1. With pipe thread sealant
applied to the pipe threads, hand­tighten the sprinkler into the sprinkler
fitting.

Step 2. Tighten the sprinkler into the
sprinkler fitting using only the W-Type
6 Sprinkler Wrench (Ref. Figure 2).
With reference to Figure 1, the W-Type
6 Sprinkler Wrench is to be applied to
the Wrench Flats.
