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-B, 5.6 K-factor,
Upright (TY315) and Pendent (TY325)
Sprinklers are intended for fire protec-
tion systems designed in accordance
with the standard installation rules
recognized by the applicable Listing
or Approval agency (e.g., UL Listing
is based on the requirements of NFPA
13, and FM Approval is based on the
requirements of the FM Loss Preven-
tion Data Sheets). Only the Style 15
or Style 20 Recessed Escutcheon, as
applicable, is to be used for recessed
pendent installations.
Installation
The TYCO Series TY-B, 5.6 K-factor,
Upright (TY315) and Pendent (TY325)
Sprinklers must be installed in accor-
dance 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 360°F (182°C)
temperature ratings.
A leak-tight 1/2 inch NPT sprinkler
joint should be obtained by applying a
minimum-to-maximum torque of 7 to 14
ft.-lbs. (9,5 to 19,0 Nm). Higher levels
of torque may distort the sprinkler inlet
and cause leakage or impairment of the
sprinkler.
Do not attempt to compensate for
insufficient adjustment in the escutch-
eon plate by under- or over-tightening
the sprinkler. Readjust the position of
the sprinkler fitting to suit.
Upright and Pendent Sprinklers
The Series TY-B Upright and Pendent
Sprinklers must be installed in accor-
dance with the following instructions.
Step 1.
Install pendent sprinklers in
the pendent position; install upright
sprinklers in the upright position.
Step 2.
With pipe-thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
fitting.
