Operation
A copper tube sealed by two stainless
steel balls holds a fusible alloy. When
the rated temperature is reached, the
alloy melts and the balls are forced
toward each other. This releases the
tension mechanism and allows 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, such as the UL Listing based
on the requirements of NFPA 13 and
FM Approval based on the require-
ments of FM Loss Prevention Data
Sheets. Use only the Style 20 or 30
Recessed Escutcheon, as applicable,
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.
General Instructions
A leak tight 1/2 in. NPT sprinkler joint
should be obtained with a torque of
7 to 14 ft-lb (9,5 to 19,0 Nm). A
leak- tight 3/4 in. NPT sprinkler joint
should be obtained with a torque of
10 to 20 ft-lb (13,4 to 26,8 Nm). Higher
levels of torque may distort the sprin-
kler inlet and cause leakage or impair-
ment of the sprinkler.
Do not attempt to compensate for
insufficient adjustment in the escutch-
eon plate by under- or over-tightening
the sprinkler. Re-adjust the position of
the sprinkler fitting to suit.
Series TY-L Upright and Pendent
Sprinklers Installation
The Series TY-L Pendent and Upright
Sprinklers must be installed in accor-
dance with the following instructions:
Step 1.
Install pendent sprinklers in the
pendent position. Install upright sprin-
klers in the upright position.
Step 2.
With pipe thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
fitting.
Step 3.
Tighten the sprinkler into the
sprinkler fitting using only the W-Type
9 Sprinkler Wrench, see Figure 7. For
wax coated sprinklers, use an 8 or 10
Series TY-L Recessed Pendent
Sprinklers Installation
The Series TY-L Recessed Pendent
Sprinkler must be installed in accor-
dance with the following instructions:
Step 1.
After installing the Style 20
or 30 Mounting Plate, as applicable,
over the sprinkler threads and 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
10 Recessed Sprinkler Wrench, see
Figure 8. With reference to Figure 1, 2,
or 3, apply the W-Type 10 Recessed
Sprinkler Wrench to the sprinkler
wrenching flanges.
Step 3.
After the ceiling has been
installed or the finish coat has been
applied, slide on the Style 20 or 30
Closure over the Series TY-L Recessed
Pendent Sprinkler and push the Closure
over the Mounting Plate until its flange
comes in contact with the ceiling.
Care and
Maintenance
The TYCO Series TY-L 5.6 and
8.0 K-factor Upright, Pendent, and
Recessed Pendent Sprinklers must be
maintained and serviced in accordance
with this section.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
Absence of an escutcheon, which is
used to cover a clearance hole, may
delay the time to sprinkler operation in
a fire situation.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated or otherwise
altered after leaving the factory. Modi-
fied or over-heated sprinklers must be
replaced. Care must be exercised to
avoid damage to the sprinklers before,
during, and after installation. Sprin-
klers damaged by dropping, striking,
wrench twist/slippage, or the like, must
be replaced.
Frequent visual inspections are rec-
ommended to be initially performed
for corrosion resistant coated sprin-
klers, after the installation has been
in. adjustable Crescent wrench. With
reference to Figures 1, 2, and 3, apply
the W-Type 9 Sprinkler Wrench to the
wrench area, or as applicable, apply
the adjustable Crescent wrench to the
wrenching flanges.
Wax Coated Sprinklers
When installing wax-coated sprinklers
with the adjustable Crescent wrench,
take care to prevent damage to the
wax coating on the sprinkler wrench
flats or frame arms and, consequently,
exposure of bare metal to the corrosive
environment:
• Open the jaws of the wrench suffi-
ciently wide to pass over the wrench
flats without damaging the wax
coating.
• Before wrench tightening the sprin-
kler, adjust the jaws of the wrench to
just contact the sprinkler flats.
• After wrench tightening the sprin-
kler, loosen the wrench jaws before
removing the wrench.
After Installation
After installation, complete the
following:
• Inspect the sprinkler wrench flats
and frame arms and retouch (repair)
the wax coating whenever the coat-
ing has been damaged and bare
metal is exposed.
• Retouch the wax coating on the
wrench flats by gently applying a
heated 1/8 in. diameter steel rod
to the damaged areas of the wax,
to smooth it back over areas where
bare metal is exposed.
NOTICE
Only retouching of the wax coating
applied to the wrench flats and frame
arms is permitted, and the retouching
is to be performed only at the time of
the initial sprinkler installation.
The steel rod should be heated only to
the point it can begin to melt the wax,
and appropriate precautions need to be
taken when handling the heated rod to
prevent the installer from being burned.
If attempts to retouch the wax coating
with complete coverage are unsuc-
cessful, additional wax can be ordered
in the form of a wax stick, the end of
which is color coded. Only the correct
color coded wax is to be used, and
retouching of wrench flats and frame
arms is only permitted at the time of
initial sprinkler installation.
With the steel rod heated as previ-
ously described, touch the rod to the
area requiring additional wax with the
rod angled downward, and then touch
the wax stick to the rod approximately
1/2 in. (12,7 mm) away from the area
requiring retouching. The wax will melt
and run down onto the sprinkler.
