General
Description
The Central Model A Upright & Pendent
Automatic Sprinklers are standard
response - standard coverage, fusible
solder type spray sprinklers designed for
use in light, ordinary, or extra hazard,
commercial occupancies such as banks,
hotels, shopping malls, factories, refiner-
ies, chemical plants, etc.
These sprinklers are available with wax
and lead coatings that may be utilized to
extend the life of copper alloy sprinklers
beyond that which would otherwise be
obtained when exposed to corrosive
atmospheres.
Although wax and lead coated sprinklers
have passed the standard corrosion tests
of the applicable approval agencies, the
testing is not representative of all possible
corrosive atmospheres. Consequently, it is
recommended that the end user be
consulted with respect to the suitability of
these corrosion resistant coatings for any
given corrosive environment. The effects
of ambient temperature, concentration of
chemicals, and gas/chemical velocity,
should be considered, as a minimum,
along with the corrosive nature of the
chemical to which the sprinklers will be
exposed.
Operation: A fusible alloy is sealed into a
bronze actuating rod (center strut) by a
stainless steel ball. When the alloy melts
at its rated temperature, the ball is forced
upward into the center strut, releasing the
two ejectors and operating the sprinkler.
WARNING
The Model A Upright & Pendent Sprin-
klers described herein must be installed
and maintained in compliance with this
document, as well as with the applicable
standards of the National Fire Protection
Association, in addition to the standards of
any other authorities having jurisdiction.
Failure to do so may impair the integrity of
these devices.
The owner is responsible for maintaining
their fire protection system and devices in
proper operating condition. The installing

Design
Criteria
The Model A Upright & Pendent
Sprinklers are Standard Response,
Standard Coverage, Spray Sprinklers
intended for fire protection systems
designed in accordance with the standard
installation rules recognized by the
applicable Listing or Approval agency.
The 2.8, 4.2, 5.6 & 8.0 K-Factor, Model A
Sprinklers (Ref. Table 1-4) are UL, ULC
Listed and NYC Approved for use in
accordance with current NFPA standards.
The 2.8, 5.6 & 8.0 K-Factor, Model A
Sprinklers (Ref. Table 1-4) are FM
Approved for use in accordance with the
FM Loss Prevention Data Sheets.
The Model A Sprinklers can be used with
any metalic flush or extended escutcheon,
provided the maximum ceiling to top of
sprinkler deflector dimension specified in
NFPA 13 is maintained. For recessed
applications, see Data Sheet 1-2.0
The Model A Upright & Pendent
Sprinklers
must be installed in accor-
dance with the following instructions.
NOTES
A leak tight 1/2 inch NPT sprinkler joint
should be obtained with a torque of 7 to
14 ft.lbs. (9,5 to 19,0 Nm). A maximum
of 21 ft.lbs. (28,5 Nm) of torque is to be
used to install 1/2 inch NPT sprinklers.
Installation
(K=2.8,4.2 & 8.0) & 1-3.0 (K=5.6) for
details.
NOTE
Inquiries concerning the appropriateness
of wax or lead coated sprinklers for a
given corrosive environment should be
submitted to the attention of the Technical
Services Department. Wax or lead coated
sprinklers are not suitable ro use in open
sprinkler applications.
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 impairment of
the sprinkler.
Step 1. Upright sprinklers must be
installed only in the upright position and
pendent sprinklers must be installed
only in the pendent position. The
deflector is to be parallel to the ceiling,
roof, or mounting surface, as applicable.
Step 2. With pipe thread sealant applied
to the pipe threads, hand tighten the
sprinkler into the sprinkler fitting.
Step 3. Tighten the sprinkler into the
sprinkler fitting using only the Combina-
tion Wrench (Ref. Figure 4), except that
an 8 or 10 inch adjustable Crescent
wrench is to be used for wax coated

Installation
(Continued)
The Model A Upright & Pendent Sprin-
klers
must be maintained and serviced in
accordance with the following instructions.
NOTES
Absence of an escutcheon which is used
to cover a clearance hole, may delay the
time to operation in a fire situation.
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 exhibiting 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 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 damage
- before, during, and after installation.
Sprinklers damaged by dropping, striking,
wrench twist/slippage, or the like, must be
replaced.
Frequent visual inspections are recom-
mended to be initially performed for wax
and/or lead coated sprinklers, after the
installation has been completed, to verify
the integrity of the wax and/or lead
coating. Thereafter, annual inspections
per NFPA 25 should suffice; however,
instead of inspecting from the floor level, a
random sampling of close-up visual
inspections should be made, so as to
better determine the exact sprinkler
condition and the long term integrity of the
wax and/or lead coating, as it may be
affected by the corrosive conditions
present.
The owner is responsible for the inspec-
tion, testing, and maintenance of their fire
protection system and devices in
compliance with this document, as well as
with the applicable standards of the
National Fire Protection Association (e.g.,
NFPA 25), in addition to the standards of
any other authorities having jurisdiction.
The installing contractor or sprinkler
manufacturer should be contacted relative
to any questions.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspection
Service.
Care &
Maintenance
sprinklers. With reference to Figure 1 &
2, both the Combination Wrench and
the adjustable Crescent wrench are to
be applied to the wrench flats only.
When installing wax coated sprinklers
with the adjustable Crescent wrench,
additional care needs to be exercised to
prevent damage to the wax coating on
the sprinkler wrench flats or frame arms
and, consequently, exposure of bare
metal to the corrosive environment. The
jaws of the wrench should be opened
sufficiently wide to pass over the wrench
flats without damaging the wax coating.
Before wrench tightening the sprinkler,
the jaws of the wrench are to be
adjusted to just contact the sprinkler
wrench flats. After wrench tightening the
sprinkler, loosen the wrench jaws before
removing the wrench.
After installation, the sprinkler wrench
flats and frame arms must be inspected
and the wax coating retouched (re-
paired) whenever the coating has been
damaged and bare metal is exposed.
The wax coating on the wrench flats
can be retouched by gently applying a
heated 1/8 inch diameter steel rod to the
areas of wax that have been damaged,
to smooth it back over areas where bare
metal is exposed.
NOTES
Only retouching of the wax coating
applied to the wrench flats and frame
arms is permitted, and the retouching is
to be performed only at the time of the
initial sprinkler installation.
The steel rod should be heated only to
the point at which it can begin to melt
the wax, and appropriate precautions
need to be taken, when handling the
heated rod, in order to prevent the
installer from being burned.
If attempts to retouch the wax coating
with complete coverage are unsuccess-
ful, additional wax can be ordered in the
form of a wax block. Care should be
exercised to assure that the proper
rated temperature wax block is ordered.
Only the correct temperature wax is to
be used, and retouching of wrench flats
and frame arms is only permitted at the
time of initial sprinkler installation. With
the steel rod heated as previously
described, touch the rod to the area
requiring additional wax with the rod
angled downward, and then touch a
portion of the wax block to the rod
approximately one-half inch away from
the area requiring retouching. The wax
will melt and run down onto the
sprinkler.
