plete, the Protection Cap is removed
and the Cover Plate Assembly installed.
Operation: When exposed to heat from
a fire, the Cover Plate, which is
soldered to the Retainer Assembly at
three points, falls away to expose the
Sprinkler Assembly. At this point the
Deflector supported by the Arms drops
down to its operational position.
The fusible link assembly is comprised
of two link halves which are joined by a
thin layer of solder. When the rated
temperature is reached, the solder
melts and the two link halves separate,
which then allows the sprinkler to
activate and flow water.

General
Description
The Central Model ELOC, 11.2
K-factor, Quick Response, Extended
Coverage Light Hazard (ECLH)
Concealed Pendent Sprinklers are
decorative fusible link sprinklers
designed for use in light hazard
occupancies such as churches,
hospitals, offices, and restaurants.
They are intended for use in automatic
sprinkler systems designed in accor-
dance with standard installation rules
(e.g., NFPA 13) for the protection of
light hazards up to a maximum cover-
age area of 324 ft
2
(30,1 m
2
), as
compared to the maximum coverage
area of 225 ft
2
(20,9 m
2
) for standard
coverage sprinklers.
Each unit includes a Cover Plate
Assembly which conceals the sprinkler
operating components above the
ceiling. The separable two-piece design
of the Cover Plate and Support Cup
Assemblies allows installation of the
sprinklers and pressure testing of the
fire protection system prior to istallation
of a suspended ceiling or application of
the finish coating to a fixed ceiling.
They also permit 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 sprinkler provides for 7/8" (22,2 mm)
of vertical adjustment, to reduce the
accuracy to which the length of fixed
pipe drops to the sprinkler must be cut.
The ELOC ECLH Concealed Pendent
Sprinkler is shipped with a Disposable
Protection Cap. The Protective Cap is
temporarily removed to install the
ELOC, and then replaced to protect the
ELOC while the ceiling is being installed
and finished. The tip of the Protection
Cap can be used to mark the center of
the ceiling hole into plaster board,
ceiling tiles, ect. by pushing the ceiling
product against the Protection Cap.
