Series TY-FRB Recessed
Horizontal Sidewall Sprinkler
Installation
The Series TY-FRB Recessed Hori-
zontal Sidewall Sprinklers must be
installed in accordance with this
section.
Step A. Recessed horizontal sidewall
sprinklers are to be installed in the
horizontal position with their center-
line of waterway perpendicular to the
back wall and parallel to the ceiling.
The word “TOP” on the Deflector is to
face towards the ceiling.
Step B. After installing the Style 10 or
20 Mounting Plate over the sprinkler
threads, hand tighten the sprinkler into
the sprinkler fitting.
Step C. Tighten the sprinkler into the
sprinkler fitting using only the W-Type
7 Recessed Sprinkler Wrench (Ref.
Figure 6). With reference to Figure
1, the W-Type 7 Recessed Sprinkler
Wrench is to be applied to the sprin-
kler wrench flats.
Step D. After the ceiling has been in-
stalled or the finish coat has been ap-
plied, slide on the Style 10 or 20 Clo-
sure over the Series TY-FRB Sprinkler
and push the Closure over the Mount-
ing Plate until its flange comes in con-
tact with the ceiling.
Care and
Maintenance
The Series TY-FRB, 5.6 K-factor, Hori-
zontal and Vertical Sidewall Sprinklers
must be maintained and serviced in
accordance 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 an escutcheon, which is
used to cover a clearance hole, may
delay the time to sprinkler operation in
a fire situation.
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 must assure that the sprin-
klers are not used for hanging any ob-
jects and that the sprinklers are only
cleaned by means of gently dusting
with a feather duster; otherwise, non-
operation in the event of a fire or inad-
vertent operation may result.
Frequent visual inspections are rec-
ommended to be initially performed
for corrosion resistant coated sprin-
klers, after the installation has been
completed, to verify the integrity of the
corrosion resistant coating. Thereaf-
ter, annual inspections per NFPA 25
should suffice; however, instead of in-
specting from the floor level, a random
sampling of close-up visual inspec-
tions should be made, so as to better
determine the exact sprinkler condi-
tion and the long term integrity of the
corrosion resistant coating, as it may
be affected by the corrosive condi-
tions present.
The owner is responsible for the in-
spection, testing, and maintenance
of their fire protection system and de-
vices in compliance with this docu-
ment, as well as with the applicable
standards of the National Fire Pro-
tection Association (e.g., NFPA 25), in
addition to the standards of any oth-
er authorities having jurisdiction. The
installing contractor or sprinkler man-
ufacturer should be contacted relative
to any questions.
It is recommended that automatic
sprinkler systems be inspected, test-
ed, and maintained by a qualified In-
spection Service in accordance with
local requirements and/or national
codes.
