Quick Response, Std. Coverage
Flush Pendent Sprinklers
Celeste™ S140, K=5.6
GENERAL DESCRIPTION
The Star Celeste S140, 5.6 K-Factor, Quick Response,
Standard Coverage, Flush Pendent Sprinklers are decora-
tive fusible solder type sprinklers designed for use in com-
mercial occupancies such as offices and restaurants.
When aesthetics is the major consideration, the Celeste
S140 should be your first choice.
The Celeste S140 features a separable escutcheon pro-
viding 3/8 inch (9,5 mm) vertical adjustment. This adjust-
ment reduces the accuracy to which the fixed pipe drops
to the sprinklers must be cut to help assure a perfect fit in-
stallation.
WARNINGS
The Celeste S140 Sprinklers described herein must be in-
stalled and maintained in compliance with this document,
as well as with the applicable standards of the National
Fire Protection Association, in addition to the standards
of any other authorities having jurisdiction. Failure to do
so may impair the integrity of these devices.
The owner is responsible for maintaining their fire protec-
tion system and devices in proper operating condition.
The installing contractor or sprinkler manufacturer should
be contacted relative to any questions.
OPERATION
The sprinkler assembly contains a small fusible solder
element. When exposed to sufficient heat from a fire, the
solder melts and enables the internal components of the
sprinkler to fall away. At this point the sprinkler activates
with the deflector dropping into its operated position (Ref-
erence Figure 1C), permitting water to flow.

DESIGN CRITERIA
The Celeste S140 (SIN S4971) Quick Response, Stand-
ard Coverage, Flush Pendent 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).
INSTALLATION
The Celeste S140 must be installed in accordance with
the following instructions:
NOTES
The Protective Cap is to remain on the sprinkler during in-
stallation and until the ceiling installation is complete. The
Protective Cap must be removed to place the sprinkler in
service.
A leak tight 1/2 inch NPT sprinkler joint should be ob-
tained with a torque of 7 to 14 ft.lbs. (9,5 to 14,0 Nm). A
maximum of 21 ft.lbs. (28,5 Nm) of torque is to be used to
install sprinklers. Higher levels of torque may distort the
sprinkler inlet with consequent leakage or impairment of
the sprinkler.
Do not attempt to compensate for insufficient adjustment
in an Escutcheon Plate by under- or over-tightening the
Sprinkler. Readjust the position of the sprinkler fitting to
suit.
1. The Sprinkler must be installed only in the pendent posi-
tion and with the Sprinkler waterway centerline perpen-
dicular to the mounting surface.
2. Install the sprinkler fitting so that the distance from the
face of the fitting to the mounting surface will be nomi-
nally 29/32 inches (23,0 mm) as shown in Figure 1A.
3. With pipe thread sealant applied to the pipe threads,
hand tighten the Sprinkler into the sprinkler fitting.
4. Wrench tighten the Sprinkler using only the #4947
Sprinkler Socket or #4948 Wrench & Socket Combina-
tion (Ref. Figure 2). The wrench recess of the #4947 is
to be applied to the sprinkler wrenching area (Ref. Fig-
ure 1A).
5. Use the “ceiling level tolerance limit” indicator on the
Protective Cap to check for proper installation height.
Relocate the sprinkler fitting as necessary.
6. After the ceiling has been completed with the 2 inch (50
mm) diameter clearance hole, push on the Escutcheon
until its flange just comes in contact with the ceiling. Do
not continue to push on the Escutcheon such that it lifts
a ceiling panel out of its normal position. If the Escutch-
eon cannot be engaged with the Sprinkler, or the the Es-
cutcheon cannot be engaged sufficiently to contact the
ceiling, relocate the sprinkler fitting as necessary.
7. Use the Protective Cap Removal Tool (Ref. Figure 3) to
remove the Protective Cap.
