Residential
Concealed Pendent Sprinklers
Stealth™ S240, K=4.2

GENERAL DESCRIPTION

The Star Stealth S240 Residential Concealed Pendent
Sprinklers are decorative sprinklers featuring a flat cover
plate designed for use in residential occupancies such as
homes, apartments, dormitories, and hotels.
They are to be used in wet pipe residential sprinkler sys-
tems for one- and two-family dwellings and mobile homes
per NFPA 13D; wet pipe residential sprinkler systems for
residential occupancies up to and including four stories in
height per NFPA 13R; or, wet pipe sprinkler systems for
the residential portions of any occupancy per NFPA 13.
Each unit includes a Cover Plate Assembly which con-
ceals the sprinkler operating components above the ceil-
ing. The separable two-piece design of the Cover Plate
and Mounting Cup Assemblies allows installation of the
sprinklers and pressure testing of the fire protection sys-
tem prior to installation of a suspended ceiling or applica-
tion of the finish coating to a fixed ceiling. They also per-
mit removal of suspended ceiling panels for access to
building service equipment without having to first shut
down the fire protection system and remove sprinklers.
Also, the separable two-piece design of the the Sprinkler
provides for 1/2 inch (12,7 mm) of vertical adjustment, to
reduce the accuracy to which the length of fixed pipe
drops to the sprinklers must be cut.
The Stealth Residential is shipped with a Disposable Pro-
tective Cap as shown in Figure 1. The Protective Cap is
temporarily removed to install the S240, and then re-
placed to protect the S240 while the ceiling is being in-
stalled and finished. The tip of the Cap can also be used
to mark the center of the ceiling hole into plaster board,
ceiling tiles, etc. by pushing the ceiling product against
the Cap. When the ceiling installation is complete, the
Cap is removed and the Cover Plate Assembly installed.
The Stealth Residential has been designed with heat sen-
sitivity and water distribution characteristics proven to
help in the control of residential fires to improve the
chance for occupants to escape or be evacuated. How-
ever, residential fire sprinkler systems are not a substitute
for intelligent fire safety awareness or fire safety construc-
tion required by building codes.

klers described herein must be installed and main-
tained in compliance with this document, as well as

be some compartment designs which cannot be fully
sprinklered in accordance with the recommendations
of NFPA 13, 13D, or 13R. In the event of this condi-
tion, consult the authorities having jurisdiction for
guidance and approval.
It is the responsibility of the installing contractor to
provide a copy of this document to the owner or their
representative, and in turn, it is the obligation of the
owner to provide a copy of this document to a suc-
ceeding owner.
The owner is responsible for maintaining their fire
protection system and devices in proper operating
condition. The installing contractor or sprinkler manu-
facturer should be contacted relative to any ques-
tions.

OPERATION

When exposed to heat from a fire, the Cover Plate, which
is soldered to the Enclosure at three points, falls away to
expose the Sprinkler Assembly. At this point the Deflector
supported by the Arms drops down to its operational posi-
tion.
The glass bulb contains a fluid which expands when ex-
posed to heat. When the rated temperature is reached,
the fluid expands sufficiently to shatter the glass bulb,
which then allows the sprinkler to activate and water to
flow.
