Description
The Tyco ® Model ELOC, 11.2 K-factor, Model ELOC, 11.2 K-factor,
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 architecturally
sensitive areas such as hotel lobbies,
office buildings, churches,
restaurants.
They are intended for use in automatic
sprinkler systems designed
accordance with standard installation
rules (e.g., NFPA 13). The fast response
thermal sensitivity rating of the Model
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
Assembly that conceals the sprinkler
operating components
ceiling. The separable
design of the Cover Plate and Support
Cup Assemblies allows installation
of the sprinklers 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 suspended ceiling panels
IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the "INSTALLER
WARNING" that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and in-
stallation can permanently damage
a sprinkler system or its components
and cause the sprinkler to fail to
operate in a fire situation or cause it
to operate prematurely.

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 3/4
inch (19,1 mm) of vertical adjustment
to provide a measure of flexibility with
regard to which the length of fixed pipe
drops to the sprinklers must be cut.
The Model
shipped with a Disposable Protective
Cap. The Protective Cap is temporarily
removed for installation, and it can be
and
replaced to help protect the sprinkler
while the ceiling is being installed
or finished. The tip of the Protective
in
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 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 Pendent
Sprinklers may be fitted with a silicone
above the
Air and Dust Seal (Ref. Fig. 4). The Air
two-piece
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.
