3. PRODUCT DESCRIPTION
The Viking Extended Coverage Hori-
zon®Mirage®Concealed Sprinkler is a
small, solder link and lever spray sprin-
kler designed for installation on con-
cealed pipe systems.
Equipped with a special deflector, the
sprinkler is designed to meet light haz-
ard density requirements for specific ex-
tended areas of coverage when the re-
quired minimum water supply is pro-
vided at the sprinkler.
After the sprinkler system has been
tested and the ceiling finish applied, the
sprinkler is hidden from view by a low
profile, small diameter cover plate, in-
stalled flush to the ceiling. The cover
plate is available in several decorative
finishes to meet design requirements.
The "push on", "thread off" design al-
lows for easy installation of the cover
plate,with up to 1/2" (12,7 mm) adjust-
ment. The "thread off" feature is de-
signed to prevent unwanted disengage-
mentofthecoverassembly,whileallow-
ing it to be removed and reinstalled to
permit temporaryremovalof ceilingpan-
els without taking the sprinkler system
out of service and removing the sprinkler.
Inside the body of the sprinkler, the de-
flector and sealing assembly are held in
position by a heat sensitive fusible link.
The sprinkler is listed as a standard

During fire conditions, when the tem-
perature around the sprinkler ap-
proaches it’s operating temperature,the
cover plate detaches. Continued heat-
ing of the exposed sprinkler causes the
fusible link to disengage, releasing the
deflector and sealing assembly. Water
flowing through the sprinkler orifice
strikes the deflector, forming a uniform
spray pattern to extinguish or control the
fire.

installed in neutral or negative pres-
sure plenums only.
D. Use care when locating sprinklers
near fixtures that can generate heat.
Do not install sprinklers where they
will be exposed to temperatures that
exceed the maximum recommended
ambient temperature for the tem-
perature rating used.
E. Viking Horizon®Mirage®Concealed
Sprinklers are not intended for use in
corrosive environments. Use only
sprinklerslistedforcorrosiveenviron-
ments when subject to corrosive at-
mospheres.
F. Adequate heat must be provided
whenVikingExtendedCoverageHo-
rizon®Mirage®ConcealedSprinklers
are installed on wet pipe systems.
When installing Viking Extended
Coverage Horizon®Mirage®Con-
cealed Sprinklers ondry systems, re-
fer to appropriate installation guides.
G. The sprinklers must be installed after
the piping is in place to prevent me-
chanical damage. Before installing,
make sure the appropriate model,
style, orifice size, and temperature
rating with the desired response
characteristic is used. Install the
sprinklers according to the following
steps:
1: Install all piping and cut the sprin-
kler drop nipple to position the
1/2" (15 mm) NPT outlet of the
reducing coupling at the desired
elevation. The drop nipple must
be perpendicular to the ceiling
and centered in a 2" (50 mm)
diameter opening in the ceiling.
2: With the sprinkler in the plastic
protective shell, apply a small
amount of pipe joint compound or
tape to the external threads of the
sprinkler only.
3: Use only the special wrenches
designed for installing Viking Ho-
rizon®Mirage®Concealed Sprin-
klers. With the sprinkler in the
plastic protective shell, place the
unit into the wrench.
4: Turn the unit clockwise to thread
thesprinkler intothe1/2"(15 mm)
NPT outlet of the coupling. DO
NOTuse the fusiblelinktostartor
thread the sprinkler into a fitting.
H. After installation, the entire system
must be tested in accordance with
the recognized installation stand-
ards. The test is applied after the
sprinkler installation to ensure no
damagehasoccurred tothesprinkler
during shipping and installation, and
to make sure the unit has beenprop-
erly tightened. If athreadleak should
occur, normally the unit must be re-
moved, new pipe joint compound or
tape applied, and reinstalled. This is
duetothefactthatwhenthejointseal
leaks, the sealing compound or tape
is washed out of the joint.
I. After testing, repairing all leaks, and
installationandpaintingoftheceiling,
the cover plate assembly may be at-
tached.
1: Remove the cover from the pro-
tective box, taking care not to
damage the cover plate assem-
bly.
2: Remove and discard the plastic
protectiveshellfrom thesprinkler.
It is recommended to retain a pro-
tective shell in the spare sprinkler
cabinet. The internal diameter of
the special Horizon®Mirage®
Concealed Sprinkler Installation
Wrenches are designed for use
with the sprinkler contained in a
protective shell.
3: From below the ceiling, gently
place the base of the cover plate
assembly over the threaded body
ofthesprinklerprotrudingthrough
the 2" (50 mm) diameter hole in
the ceiling.
4: Push the cover plate assembly
onto the sprinkler until the unfin-
ished brass flange of the cover
plate base touches the ceiling.
The maximum adjustmentavailable is
1/2" (12,7 mm). DO NOT MODIFY
THE UNIT. If necessary, re-cut the
sprinkler drop nipple.
J. DISASSEMBLY: The "thread off" de-
sign of the cover plate assembly al-
lows the cover plate assembly to be
removed and reinstalled to permit
temporary removal of ceiling panels
without taking the sprinkler system
outofserviceandremovingthesprin-
kler. To remove the cover plate as-
sembly:
1: From below the ceiling, grasp the
cover plate and gently turn it
counterclockwise.
If it is necessary to remove the entire
sprinkler, the system must be removed
from service. See Maintenance instruc-
tionsandfollow allwarningsandinstruc-
tions.
K. RE-ASSEMBLY: The push-on fea-
ture of the cover plate assembly al-
lows easy installation of the cover
plate.
1: From below the ceiling, gently
place the base of the cover plate
assembly over the threaded body
of the sprinkler.
2: Push the cover plate assembly
onto the sprinkler until the unfin-
ished brass flange of the cover
plate base touches the ceiling.

8. MAINTENANCE
NOTICE: The owner is responsible for
maintaining the fire protection system
and devices in proper operating condi-
tion. For minimum maintenance and in-
spection requirements, refer to the ap-
propriate National Fire Protection Asso-
ciation Pamphlet that describes care
and maintenance of sprinkler systems.
In addition, the Authority Having Juris-
diction may have additional mainte-
nance requirements which must be fol-
lowed.
A. The sprinklers must be inspected on
a regular basis for corrosion, me-
chanical damage, obstructions,
paint, etc. The frequency of the in-
spections may vary due to corrosive
atmospheres, water supplies, and
activity around the device.
B. Sprinklers or cover plate assemblies
that have been field painted or me-
chanically damaged must be re-
placed immediately. Sprinklers
showing signs of corrosion shall be
tested and/or replaced immediately
as required. Installation standards
require sprinklers to be tested and, if
necessary, replaced immediately af-
ter a specified term of service. For
Viking Extended Coverage Horizon®
Mirage®Concealed sprinklers, refer
to the Installation Standards and the
Authority Having Jurisdiction for the
specified period of time after which
testing and/or replacement is re-
quired. Sprinklers and cover plate
assemblies that have operated can-
not be reassembled or re-used, but
must be replaced. When replace-
ment is necessary, use only new
sprinklers and cover plate assem-
blies.
C. The sprinkler discharge pattern is
critical for proper fire protection.
Nothing should be hung from, at-
tached to, or otherwise obstruct the
discharge pattern. All obstructions
must be immediately removed or, if
necessary, additional sprinklers in-
stalled.
D. When replacing existing sprinklers,
the system must be removed from
service. Refer totheappropriatesys-
tem description and/or valve instruc-
tions. Prior to removing the system
from service, notify all Authorities
Having Jurisdiction. Consideration
