Description
The Tyco®RAVEN™ Institutional Pen-
dent and Horizontal Sidewall Sprin-
klers are quick response spray sprin-
klers designed for use in areas such
as correctional, detention, and mental
health care facilities, as well as other
commercial buildings. Both the pen-
dent and horizontal sidewall styles
are available for standard or extended
coverage applications.
Features:
The RAVEN assembly increases•
the difficulty of tampering with the
sprinkler that may cause a false
activation.
The tamper resistant nature of the•
RAVEN helps reduce the opportu-
nity for individuals to injure them-
selves or others with components of
a fire sprinkler.
The RAVEN optimizes an aestheti-•
cally appealing flush design that
conceals all of the operating parts.

IMPORTANT
Always refer to Technical Data
Sheet TFP700 for the “INSTALLER
WARNING” that provides cautions
with respect to handling and instal-
lation of sprinkler systems and com-
ponents. Improper handling and in-
stallation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

Design
Criteria
Standard Coverage Criteria:
The RAVEN™, Standard Coverage,
Institutional Pendent and Horizon-
tal Sidewall Sprinklers (TY3281 and
TY3381) are intended for use with fire
protection systems designed in ac-
cordance with the standard instal-
lation rules recognized by the ap-
plicable Listing or Approval agency
(e.g., UL Listing is based on NFPA 13
requirements).
The RAVEN Horizontal Sidewall Sprin-
kler (TY3381) must be installed with
a deflector to ceiling distance of 4 to
12 inches (100 to 300 mm). To meet
this requirement, the centerline of the
sprinkler waterway must be located
4-7/16 to 12-7/16 inches (112,7 to 315,9
mm) below the ceiling (Ref. Figure 7).
Extended Coverage Criteria:
The RAVEN™, Extended Coverage,
Institutional Pendent and Horizon-
tal Sidewall Sprinklers (TY3282 and
TY3382) must be installed in accor-
dance with the flow rate criteria pro-
vided in Table A and they must be
installed and utilized in light hazard
occupancies, under smooth, flat, hori-
zontal ceilings as outlined in the appli-
cable installation standard recognized
by the Listing or Approval agency
(e.g., UL Listing is based on NFPA 13
requirements).
The RAVEN, Extended Coverage, Hor-
izontal Sidewall Sprinkler (TY3382)
must be installed with a deflector to
ceiling distance of 4 to 12 inches (100
to 300 mm). To meet this requirement,
the centerline of the sprinkler water-
way must be located 4-7/16 to 12-7/16
inches (112,7 to 315,9 mm) below the
ceiling (Ref. Figure 7).
General Criteria:
Only the Escutcheons shown in Fig-
ures 5 and 6 can be utilized with the
RAVEN Institutional Sprinklers. A max-
imum of two Spacers can be used for
adjustment of the Escutcheons.
NOTICE
Use of more than two Spacers may
result in disabling the tamper resis-
tant design of the RAVEN Sprinklers
and its principle function of helping
to avoid false sprinkler operations and
the opportunity for individuals to in-
jure themselves or others with compo-
nents of the sprinkler.
Integrity of the tamper resistant de-
sign of the RAVEN Escutcheons is
dependent on the piping installation
design. When installed properly, the
Escutcheon is held fast (i.e., tight with
no movement or gap) to the mounting
surface (ceiling or wall, as applicable)
by the tightening of the sprinkler as-
sembly into the sprinkler fitting. In or-
der to accomplish a proper installation,
the sprinkler fitting must be properly
located with respect to distance from
the face of the sprinkler fitting to the
face of the mounting surface (Ref. Fig-
ures 5 and 6); the sprinkler fitting be-
ing rigidly secured and held immobile;
and, the centerline of the sprinkler fit-
ting being perpendicular to the mount-
ing surface to assure that the escutch-
eon sits squarely against the mounting
surface around the entire perimeter of
the Institutional Escutcheon.
Figure 7 illustrates a technique that
can be used to help adjust the loca-
tion of the sprinkler fitting; to help as-
sure immobility of the sprinkler fitting;
and, to help maintain perpendicularity
of the sprinkler fitting to the mounting
surface. Figure 7 illustrates a horizon-
tal installation; however, it can be ap-
plied to a pendent installation as well.
When applied, the technique shown
in Figure 7 allows the sprinkler/sup-
ply pipe to be pulled back into the
mounting surface from behind the wall
or above the ceiling before tightening
the retaining flange set screw, which
will help overcome problems with as-
suring that the escutcheon is held fast
(i.e., tight with no movement or gap) to
the mounting surface. Also, this meth-
od of installation allows for easy re-
moval of the sprinkler/supply pipe for
installations where there is access be-
hind the wall or above the ceiling.

NOTES
Requirement is based on minimum flow in GPM from each sprinkler.1.
The indicated residual pressures are based on the nominal K-factor.2.
The centerline of the sprinkler waterway is located 7/16 inch (11,1 mm) below the deflector (Ref. Figure 7).3.
Minimum spacing is for lateral distance between sprinklers located along a single wall. Otherwise adjacent sprinklers (i.e., sidewall sprin-4.
klers on an adjacent wall, on an opposite wall, or pendent sprinklers) must be located outside of the maximum listed protection area of the
extended coverage sidewall sprinkler being utilized.

Operation
In the standby condition, the unique
features of the RAVEN provide a tam-
per resistant sprinkler design that
helps reduce the opportunity for indi-
viduals to injure themselves or others
with components of a fire sprinkler.
The RAVEN has been specifically de-
signed to minimize components, as
well as holes or shapes that could
provide a point for securing an exter-
nal non-sprinkler associated object.
Also, when properly installed, the es-
cutcheon is held fast to the ceiling or
wall to deter its removal. The shape of
the sprinkler and escutcheon cannot
be grasped easily, which further de-
ters tampering.
A link assembly covers the sealing as-
sembly. The link is soldered with an
eutectic solder that melts when ex-
posed to heat. When the link reaches
its rated temperature, the link sepa-
rates and releases the sealing assem-
bly, allowing the deflector assembly
to extend from the body and water to
flow.
Installation
The Tyco®RAVEN™ Institutional
Sprinklers must be installed in accor-
dance with the following instructions:
NOTICE
Refer to the Design Criteria section for
important information regarding the
piping installation design and its ef-
fect on maintaining the integrity of the
tamper resistant design of the Institu-
tional Escutcheons.
A 1/2 inch NPT sprinkler joint should
be obtained with a minimum to max-
imum torque of 7 to 14 ft.lbs. (9,5 to
19,0 Nm). Higher levels of torque may
damage the sprinkler with consequent
leakage or impairment of the sprinkler.
Do not attempt to compensate for
improper location of the sprinkler fit-
ting by under-or over-tightening the
sprinkler.
After the installation is complete,
make certain that the RAVEN Es-
cutcheon is held fast (i.e., tight with
no movement or gap) to the mounting
surface and that the Escutcheon sits
squarely against the mounting sur-
face around the entire perimeter of the
Escutcheon.
PENDENT SPRINKLERS
Step 1. The RAVEN Pendent Sprinkler
must be installed pendent and with
the centerline of the waterway perpen-
dicular to the ceiling.
Step 2. With the Escutcheon in place
and with pipe thread sealant applied
to the pipe threads, hand tighten the
sprinkler into the sprinkler fitting using
the W-type 25 Sprinkler Wrench.
Note: The sprinkler has intention-
ally been designed to be difficult to
grasp by hand; therefore, the use of
the W-type 25 Sprinkler Wrench for
hand tightening will assist in thread-
ing the sprinkler. Also use of the W-
type 25 Sprinkler Wrench will help
avoid damage to the Sprinkler during
installation.
Step 3. Wrench tighten the Sprinkler
using only the W-Type 25 Sprinkler
Wrench (Ref. Fig. 3) with the wrench
prongs fully engaged with the Sprin-
kler Wrenching Notches. The wrench
prongs are designed to engage with
the wrenching notches in the sprin-
kler body. The wrench prongs are
also uniquely spaced to align with the
sprinkler wrenching notches in one
position.
Note: To help prevent slippage of the
Sprinkler Wrench and while using a 1/2
inch ratchet drive, place one hand over
the Sprinkler Wrench while tightening
with the other hand.
Step 4. After the installation is com-
plete, make certain that the RAVEN
Escutcheon is held fast to the mount-
ing surface and that it sits squarely
against the ceiling around its entire
perimeter. When using the technique
shown in Figure 7, the Escutcheon can
be pulled up onto the ceiling by pulling
up on the sprinkler/supply pipe and
then tighten the Retaining Flange Set
Screw. See Figure 3 inset for post in-
stallation identification.
Note: If the Escutcheon is NOT held
fast (i.e., tight with no movement or
gap) to the mounting surface and as
an option to relocating the sprinkler
pipe fitting (i.e., increasing the “face of
fitting” to “face of mounting surface”
distance) up to two Adjustment Spac-
er Rings as shown in Figure 3 may be
utilized. Each Adjustment Spacer Ring
can account for 0.075 inches of gap
between the Escutcheon and mount-
ing surface. Therefore, if the gap is
greater than 0.150 inches, the sprin-
kler fitting will need to be relocated
to assure proper installation of the
RAVEN Sprinkler and Escutcheon.
HORIZONTAL SIDEWALL
SPRINKLERS
Step 1. The RAVEN Horizontal Side-
wall Sprinkler must be installed with
the centerline of their waterway paral-
lel with the ceiling and perpendicular
to the back wall.
Step 2. With the Escutcheon in place
and with pipe thread sealant applied
to the pipe threads, hand tighten the
sprinkler into the sprinkler fitting using
the W-type 25 Sprinkler Wrench.
Note: The sprinkler has intention-
ally been designed to be difficult to
grasp by hand; therefore, the use of
the W-type 25 Sprinkler Wrench for
hand tightening will assist in thread-
ing the sprinkler. Also use of the W-
type 25 Sprinkler Wrench will help
avoid damage to the Sprinkler during
installation.
Step 3. Wrench tighten the Sprinkler
using only the W-Type 25 Sprinkler
Wrench (Ref. Fig. 4) with the wrench
prongs fully engaged with the Sprin-
kler Wrenching Notches. The wrench
prongs are designed to engage with
the wrenching notches in the sprin-
kler body. The wrench prongs are
also uniquely spaced to align with the
sprinkler wrenching notches in one
position so as to assure that the sprin-
kler defector is properly positioned
with respect to the ceiling.
Note: To help prevent slippage of the
Sprinkler Wrench and while using a 1/2
inch ratchet drive, place one hand over
the Sprinkler Wrench while tightening
with the other hand.
Note: Upon completion of tighten-
ing the sprinkler, the word “UP” on the
wrench must be positioned towards
the ceiling. The use of a level applied
the flat of the wrench below the word
“UP” is recommended to help as-
sure that the sprinkler deflector is po-
sitioned correctly with respect to the
ceiling.
Step 4. After the installation is com-
plete, make certain that the Escutch-
eon is held fast to the mounting sur-
face and that it sits squarely against
the wall around its entire perimeter.
When using the technique shown
in Figure 7, the Escutcheon can be
pulled back onto the wall by pulling
back on the sprinkler/supply pipe and
then tighten the Retaining Flange Set
Screw.
Note: If the Escutcheon is NOT held
fast (i.e., tight with no movement or
gap) to the mounting surface and as
an option to relocating the sprinkler
pipe fitting (i.e., increasing the “face of
fitting” to ”face of mounting surface”
distance) up to two Adjustment Spac-
er Rings as shown in Figure 4 may be
utilized. Each Adjustment Spacer Ring
can account for 0.075 inches of gap
between the Escutcheon and mount-
ing surface. Therefore, if the gap is
greater than 0.150 inches, the sprinkler
fitting will need to be relocated to as-
sure proper installation of the RAVEN
Sprinkler and Escutcheon.
Step 5. After all the horizontal sidewall
sprinklers are installed, use the W-
type 25 Sprinkler Wrench to verify that
the each sprinkler defector is proper-
ly aligned with respect to the ceiling.
See Step 3. See Figure 4 inset for post
installation identification.

Care and
Maintenance
The Tyco®RAVEN™ Institutional
Sprinklers must be maintained and
serviced in accordance with the fol-
lowing instructions:
NOTICE
Service inspections should be made
on a regular basis to detect possible
damage or alterations to the sprinkler
and escutcheon. Inspections should
include making certain that the Insti-
tutional Escutcheon is held fast to the
mounting surface. Damaged or altered
sprinklers are to be replaced immedi-
ately to avoid personal injury and to
prevent use for causing personal inju-
ry, as well as to maintain the sprinkler
system in an operative condition.
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-
tems must be obtained from the prop-
er authorities and all personnel who
may be affected by this action must be
notified.
Sprinklers which are found to be leak-
ing or exhibiting visible signs of corro-
sion must be replaced.
Automatic sprinklers must never be
painted, plated, coated, or otherwise
altered after leaving the factory. Modi-
fied or over-heated sprinklers must be
replaced.
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.
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.
Automatic sprinkler systems should
be inspected, tested, and maintained
by a qualified Inspection Service in
accordance with local requirements
and/or national codes.
