Installation
The TYCO RAPID RESPONSE Series
LFII Residential Flush Pendent Sprin-
klers (TY2284) must be installed in
accordance with this section.
General Instructions
The Protective Cap is to remain on the
sprinkler during installation until the
ceiling installation is complete. The
Protective Cap must be removed to
place the sprinkler in service.
A leak-tight 1/2 in. NPT sprinkler joint
should be obtained by applying a min-
imum-to-maximum torque of 7 to 14
lb-ft (9,5 to 19,0 N∙m). Higher levels of
torque can distort the sprinkler Inlet
with consequent leakage or impairment
of the sprinkler.
Do not attempt to compensate for
insufficient adjustment in the sprinkler
by under- or over-tightening the Sprin-
kler/Support Cup Assembly. Re- adjust
the position of the sprinkler fitting to
suit.
Each sprinkler must be inspected
before installation. Do not use any
sprinkler that exhibits any deformations
or cracks, including cracks on the pro-
tective cap.
Step 1. The sprinkler must be installed
only in the pendent position and with
the sprinkler waterway centerline per-
pendicular to the mounting surface.
Step 2. Install the sprinkler tting so
that the distance from the face of the
tting to the mounting surface will be
nominally 29/32 in. (23,0 mm) as shown
in Figure 1A.
Step 3. With pipe thread sealant
applied to the pipe threads, hand-
tighten the sprinkler into the sprinkler
tting.
Step 4. Tighten the sprinkler using
only the Sprinkler Socket or Wrench
& Socket Combination (Figure 2). The
wrench recess of the socket is to be
applied to the sprinkler wrenching area
(Figure 1A).
Step 5. Use the “ceiling level toler-
ance limit” indicator on the Protective
Cap to check for proper installation
height. Relocate the sprinkler tting as
necessary. If desired, the Protective
Cap may also be used to locate the
center of the clearance hole by gently
pushing the ceiling material against the
center point of the Cap.
Step 6. After the ceiling has been com-
pleted with the 2 in. (50 mm diameter
clearance hole, use the Protective Cap
Removal Tool (Figure 3) to remove
the Protective Cap and then push on
the Escutcheon until its ange just
comes in contact with the ceiling. Do
not continue to push the Escutcheon
such that it lifts a ceiling panel out of
its normal position. If the Escutcheon
cannot be engaged with the sprinkler,
or the Escutcheon cannot be engaged
sufciently to contact the ceiling, relo-
cate the sprinkler fitting as necessary.
Care and
Maintenance
The TYCO RAPID RESPONSE Series
LFII Residential Flush Pendent Sprin-
klers (TY2284) 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, obtain permission to
shut down the affected fire protection
systems from the proper authorities
and notify all personnel who may be
affected by this action.
Absence of the outer piece of an
escutcheon, which is used to cover
a clearance hole, can delay sprinkler
operation in a fire situation.
The owner must assure that the sprin-
klers are not used for hanging any
objects and that the sprinklers are only
cleaned by means of gently dusting
with a feather duster; otherwise, non-
operation in the event of a fire or inad-
vertent operation may result.
Sprinklers which 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 overheated 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.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION (e.g., NFPA 25), in addi-
tion to the standards of any authorities
having jurisdiction. Contact the install-
ing contractor or product manufacturer
regarding any questions.
Automatic sprinkler systems are
recommended to be inspected,
tested, and maintained by a qualified
Inspection Service in accordance with
local requirements and/or national
codes.
