Extra Large Orifice Concealed Pendent Sprinklers
Quick and Standard Response, Extended Coverage
General
Description
The TYCO Model ELOC, 11.2 K-fac-
tor, Extended Coverage, Light Hazard,
Extra Large Orifice Concealed (ELOC)
Pendent Sprinklers are decorative,
fast response solder type sprinklers
featuring a flat cover plate designed
to conceal the sprinkler. When limited
water pressure is available, the ELOC
is the best choice for architectural-
ly sensitive areas such as hotel lob-
bies, office buildings, churches, and
restaurants.
They are intended for use in automatic
sprinkler systems designed in accor-
dance with standard installation rules
(e.g., NFPA 13). The fast response
thermal sensitivity rating of the Mod-
el ELOC (TY5522) provides for a quick
response extended coverage (QREC)
rating up to an 18 ft. x 18 ft. coverage
area.
Each unit includes a Cover Plate As-
sembly that conceals the sprinkler op-
erating components above the ceiling.
The separable two-piece design of the
Cover Plate and Support Cup Assem-
blies allows installation of the sprin-
klers and pressure testing of the fire
protection system prior to installation
of a suspended ceiling or application
of the finish coating to a fixed ceiling.
They also permit removal of suspend-
ed ceiling panels for access to build-
ing service equipment without having
to first shut down the fire protection
system and remove sprinklers.
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cau-
tions with respect to handling
and installation of sprinkler sys-
tems and components. Improp-
er handling and installation can
permanently damage
kler system or its components
and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

Also, the separable two-piece design
of the Sprinkler provides for 3/4 inch
(19,1 mm) of vertical adjustment to
provide a measure of flexibility with re-
gard to which the length of fixed pipe
drops to the sprinklers must be cut.
The Model ELOC Sprinklers are
shipped with a Disposable Protec-
tive Cap. The Protective Cap is tem-
porarily removed for installation, and
it can be replaced to help protect the
sprinkler while the ceiling is being in-
stalled or finished. The tip of the Pro-
tective Cap can also be used to mark
the center of the ceiling hole into plas-
ter board, ceiling tiles, etc. by gently
pushing the ceiling product against
the Protective Cap. When the ceiling
installation is complete the Protective
Cap is removed and the Cover Plate
Assembly installed.
As an option, the Model ELOC Pen-
dent Sprinklers may be fitted with a
silicone Air and Dust Seal (Ref. Fig. 4).
The Air and Dust Seal is intended for
sensitive areas where it is desirable
to stop air and dust travel through the
cover plate from the area above the
ceiling.
