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.

No. 2-7.0
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 ft2(30,1 m2), as
compared to the maximum coverage
area of 225 ft2(20,9 m2) 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.

orifice is sealed with a gasketed spring
plate (Belleville Seal) consisting of a
beryllium nickel disc spring that is sealed
on both its inside and outside edges with a
TeflonTM gasket. The arms and deflector
are bronze, and the support cup is steel.
The cover plate and retainer assembly are
brass.

Criteria
The Model ELOC ECLH Concealed Pendent Sprinklers are UL and C-UL listed and NYC Approved (MEA 7-95-E), for use in
light hazard occupancies, using the design criteria in Table 1 as well as any additional requirements specified in current
NFPA 13 Standards for Extended Coverage Pendent Sprinklers.
The Model ELOC ECLH Concealed Pendent Sprinklers are only listed with the Series ELOC Concealed Cover Plates. The
minimum lateral spacing between the ELOC ECLH Concealed Pendent Sprinkers, to prevent cold soldering, is 8 feet
(2,4 m).
The Model ELOC ECLH Concealed Pendent Sprinklers may be used with the "Clean Room Seal", see data sheet 28-4.0.
The use of this seal changes the thermal sensitivity from quick response to standard response.
The Support Cup of the Model ELOC ECLH Concealed Pendent Sprinkler has several slots in the base of the cup which
allows heat from a fire to flow past the thermal sensitive operating element accelerating sprinkler activation. Due to the
presence of these slots, the installation of these sprinklers in ceilings which have positive pressure in the space above, is
not permitted.

Table 1 - UL and C-UL Listing Criteria for the Installation of Model ELOC
Extended Coverage Light Hazard Concealed Pendent Sprinklers
Installation
The Model ELOC ECLH Concealed
Pendent Sprinklers must be installed
in accordance with the following
instructions.
NOTES
A leak tight 3/4 inch NPT sprinkler
joint should be obtained with a torque
of 10 to 20 ft.lbs. (13,4 to 26,8 Nm). A
maximum of 30 ft.lbs. (40,7 Nm) of
torque is to be used to install 3/4 inch
NPT sprinklers. Higher levels of
torque may distort the sprinkler inlet
with consequent leakage or impair-
ment of the sprinkler.
Do not attempt to make up for
insufficient adjustment in the escutch-
eon plate by under- or overtightening
the sprinkler. Readjust the position of
the sprinkler fitting to suit.
Step 1. The sprinkler must only be
installed only in the pendent position
and with the centerline of the sprinkler
perpendicular to the mounting
surface.
Step 2. Remove the Protective Cap.
Step 3. With pipe thread sealant
applied to the pipe threads, hand
tighten the sprinkler into the sprinkler
fitting.
Step 4. Wrench tighten the Sprinkler
using only the ELOC Sprinkler
Wrench (Ref. Figure 4). The ELOC
Sprinkler Wrench is to be applied to
the Sprinkler Wrench flats only.
Step 5. Replace the Protective Cap
by pushing it upwards until it bottoms
out against the Support Cup. The
Protective Cap helps prevent
dammage to the Deflector and Arms
during ceiling installation and/or
during application of the finish coating
of the ceiling. It may also be used to
locate the center of the clearance
holes by gently pushing the ceiling
material up against the center point of
the Protective Cap.
NOTE
As Long as the Protective Cap
remains in place, the system is
considered to be "Out of Service"
Step 6. After the ceiling has been
completed with the 2-1/2 inch
(66,7 mm) diameter clearance hole
and in preparation for installing the
Cover Assembly, remove and discard
the Protective Cap, and verify that the
Deflector moves up and down freely.
If the Sprinkler has been damaged
and the Deflector does not move up
and down freely, replace the entire
Sprinkler Assembly. Do not attempt
to modify or repair a damaged
sprinkler.
Step 7. Screw on the Cover Plate/
Retainer Assembly until its flange just
comes in contact with the ceiling. Do
not continue to screw on the Cover
Plate/Retainer Assembly such that it
lifts a ceiling panel out of its normal
position. If the Cover Plate/Retainer
Assembly cannot be engaged
sufficiently to contact the ceiling, the
sprinkler fitting must be repositioned.

The Model ELOC ECLH Concealed
Pendent Sprinklers must be maintained
and serviced in accordance with the
following instructions.
NOTES
Absence of the Cover Plates which is
used to cover a clearance hole, may
delay the time to operation in a fire
situation.
When properly installed, there is a
nominal 3/32 inch (2,4 mm) air gap
between the lip of the Cover Plate and
the ceiling. This air gap is necessary for
proper operation of the sprinkler. If the
ceiling is to be repainted after the
installation of the sprinkler, care must
be exercised to ensure that the new
paint does NOT seal off any of the air
gap.
Factory painted Cover Plates MUST
NOT be repainted. They should be
replaced, if necessary, by factory
painted units.
Do not pull the Cover Plates relative to
the Retainer Assembly. Separation may
result.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system it
controls, permission to shut down the
affected fire protection systems must be
obtained from the proper authorities. All
personnel who may be affected by this
action must be notified.
Sprinklers which are found to be leaking
or exibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
shipped or stored where their tempera-
tures will exceed 100°F/38°C and they
must never be painted, plated, coated
or otherwise altered after leaving the
factory. Modified or over-heated
sprinklers must be replaced.
Care must be exercised to avoid
damage - before, during, and after
installation. Sprinklers damaged by
dropping, striking, wrench twist/
slippage, or the like, must be replaced.
If a sprinkler must be removed for some
reason, do not reinstall it or a replace-
ment without reinstalling the Cover
Plate Assembly. If a Cover Plate
Assembly becomes dislodged during
service, replace it immediatly.
