Tyco ELOC User manual

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.
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.
NOTICE
The Model ELOC Pendent Sprinklers
described herein must be installed
and maintained in compliance with
this document and with the applica-
ble standards of the National Fire Pro-
tection Association, in addition to the
standards of any authorities having ju-
risdiction. Failure to do so may impair
the performance of these devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

Operation
When exposed to heat from a fire, the
Cover Plate, normally soldered to the
Retainer at three points, falls away to
expose the Sprinkler Assembly. At this
point the Deflector supported by the
Guide Pins drops down to its opera-
tional position.
When the rated temperature of the
Solder Link Element is reached, the
Link Element separates, allowing the
sprinkler to activate and flow water.

HYDRAULIC DESIGN CRITERIA

Design
Criteria
The Model ELOC (TY5522) Pendent
Sprinklers are UL and C-UL Listed for
use in light hazard occupancies, using
the design criteria in Table A, in addi-
tion to the requirements specified in
the current NFPA 13 for extended cov-
erage pendent sprinklers.
The ELOC Pendent Sprinklers are only
listed and approved with the ELOC
Concealed Cover Plates having a fac-
tory applied finish.
The ELOC must not be used in appli-
cations where the air pressure above
the ceiling is greater than that below.
Down drafts through the Support Cup
could delay sprinkler operation in a
fire situation.
Installation
The TYCO Model ELOC must be in-
stalled in accordance with this
section.
General Instructions
A leak tight 3/4 inch NPT sprinkler
joint should be obtained with a mini-
mum to maximum torque of 10 to 20
ft.-lbs. (13,4 to 26,8 Nm). Higher levels
of torque may distort the sprinkler in-
let with consequent leakage or impair-
ment of the sprinkler.
Do not attempt to compensate for in-
sufficient adjustment in the Sprinkler
Assembly by under-or over-tightening
the Sprinkler/Support Cup Assembly.
Readjust the position of the sprinkler
fitting to suit.
Step 1. The sprinkler must only be in-
stalled in the pendent position and
with the centerline of the sprinkler per-
pendicular to the mounting surface.
Step 2. Remove the Protective Cap.
Step 3. With pipe thread sealant ap-
plied to the pipe threads, hand tighten
the sprinkler into the sprinkler fitting.
Step 4. Wrench tighten the sprinkler
using only the W-Type 18 Sprinkler
Wrench (Ref. Figure 3). The W-Type
18 Sprinkler Wrench is to be applied
to the Sprinkler as shown in Figure 3.
Step 5. Replace the Protective Cap
(Ref. Figure 2) by pushing it upwards
until it bottoms out against the Sup-
port Cup. The Protective Cap helps
prevent damage 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 hole

by gently pushing the ceiling material
against the center point of the Protec-
tive Cap.
NOTICE
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 (63,5
mm) diameter clearance hole and in
preparation for installing the Cover
Plate 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 Sprin-
kler assembly. Do not attempt to mod-
ify or repair a damaged sprinkler.
Step 7. When installing an Air and
Dust Seal, refer to Figure 4, otherwise
proceed to Step 8. To attach the Air
and Dust Seal, verify the angle of the
outside edge of the seal is oriented
according to Figure 4. Start the edge
of the Retainer in the grooved slot of
the Air and Dust Seal and continue
around the retainer until the entire Air
and Dust Seal is engaged.
Step 8. Screw on the Cover Plate/
Retainer Assembly until the Retainer
(Figure 2) or Air and Dust Seal (Fig-
ure 4) contacts 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 with the Support
Cup or the Cover Plate/Retainer As-
sembly cannot be engaged sufficient-
ly to contact the ceiling, the Sprinkler
Fitting must be repositioned.
Care and
Maintenance
The TYCO Model ELOC must be
maintained and serviced in accor-
dance with this section.
Before closing a fire protection sys-
tem main control valve for mainte-
nance work on the fire protection sys-
tem that it controls, permission to shut
down the affected fire protection sys-
tem must be obtained from the prop-
er authorities and all personnel who
may be affected by this action must
be notified.
Absence of the Cover Plate Assem-
bly may delay sprinkler 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 Cov-
er Plate and the ceiling, as shown in
Figure 2. This air gap is necessary for
proper operation of the sprinkler. If the
ceiling is to be repainted after the in-
stallation 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 re-
placed, if necessary, by factory paint-
ed units. Non-factory applied paint
may adversely delay or prevent sprin-
kler operation in the event of a fire.
Do not pull the Cover Plate relative to
the Enclosure. Separation may result.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or other-
wise altered after leaving the factory.
Modified sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid dam-
age to the sprinklers before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be
replaced. Also, replace any sprinkler
that has a cracked bulb or that has
lost liquid from its bulb. (Ref. Installa-
tion Section.)
The owner is responsible for the in-
spection, testing, and maintenance of
their fire protection system and devic-
es in compliance with this document,
as well as with the applicable stan-
dards of the National Fire Protection
Association (e.g., NFPA 25), in addi-
tion to the standards of any other au-
thorities having jurisdiction. Contact
the installing contractor or product
manufacturer with any questions.
Automatic sprinkler systems should
be inspected, tested, and maintained
by a qualified Inspection Service in
accordance with local requirements
and/or national codes.
