Operation
A copper tube sealed by two stainless
steel balls holds a fusible alloy. When
the rated temperature is reached, the
alloy melts, the balls are forced toward
each other releasing the tension mech-
anism, allowing the sprinkler to operate.
Design
Criteria
The TYCO Series TY-L, 5.6 and
8.0 K-factor, Upright, Pendent, and
Recessed Pendent Sprinklers are
intended for fire protection systems
designed in accordance with the stan-
dard installation rules recognized by the
applicable Listing or Approval agency
(e.g., UL Listing is based on the require-
ments of NFPA 13, and FM Approval
is based on the requirements of FM’s
Loss Prevention Data Sheets). Only
the Style 20 or 30 Recessed Escutch-
eon, as applicable, are to be used for
recessed pendent installations.
Installation
The TYCO Series TY-L, 5.6 and
8.0 K-factor, Upright, Pendent, and
Recessed Pendent Sprinklers must
be installed in accordance with this
section:
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 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). Higher levels
of torque may distort the sprinkler inlet
and cause leakage or impairment of the
sprinkler.
Do not attempt to make-up for insuf-
ficient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Readjust the position of the
sprinkler fitting to suit.
Series TY-L Pendent and Upright
Sprinkler Installation
The Series TY-L Pendent and Upright
Sprinklers must be installed in accor-
dance with this section.
Pendent sprinklers are to be installed
in the pendent position, and upright
sprinklers are to be installed in the
upright position.
Step 1. With pipe thread sealant
applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step 2. Tighten the sprinkler into the
sprinkler fitting using only the W-Type
9 Sprinkler Wrench (Ref. Figure 7),
except that an 8 or 10 inch adjust-
able Crescent wrench is to be used
for wax coated sprinklers. With refer-
ence to Figures 1, 2, and 3, the W-Type
9 Sprinkler Wrench is to be applied to
the wrench area, or as applicable, the
adjustable Crescent wrench is to be
applied to the wrenching flanges.
When installing wax coated sprinklers
with the adjustable Crescent wrench,
additional care needs to be exercised
to prevent damage to the wax coating
on the sprinkler wrench flats or frame
arms and, consequently, exposure of
bare metal to the corrosive environ-
ment. The jaws of the wrench should be
opened sufficiently wide to pass over
the wrench flats without damaging the
wax coating. Before wrench tightening
the sprinkler, the jaws of the wrench are
to be adjusted to just contact the sprin-
kler wrench flats. After wrench tight-
ening the sprinkler, loosen the wrench
jaws before removing the wrench.
