3. PRODUCT DESCRIPTION
Viking Horizon®Mirage®Quick Re-
sponse Extended Coverage Concealed
PendentSprinklersaresmall,solderlink
and lever spray sprinklers designed for
installation on concealed pipe systems.
Equipped with a special deflector, the
sprinkler is designed to meet Light-Haz-
arddensityrequirementsforspecificex-
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 allows
foreasyinstallationofthecoverplate,with
up to 1/2" (12,7 mm) of vertical adjust-
ment.The“thread-off”featureis designed
to prevent unwanted disengagement of
the cover assembly. The cover assembly
can be removed and reinstalled to permit
temporary removal of ceiling panels with-
out taking the sprinkler system out of ser-
vice and removing the sprinkler .
Inside the body of the Horizon®Mirage®
Quick Response Extended Coverage
Concealed Sprinkler, the deflector and
sealing assembly are held in position by
a fast-acting heat-sensitive fusible link.
The sprinklers are listed as quick re-
sponse sprinklers when installed ac-
cordingtothelisted16ft.x16ft.(4,9mx
4,9 m) or 18 ft. x 18 ft. (5,5 m x 5,5 m)
spacing. (Refer to the approval chart on
page 58 d for additional listing.)
Duringfireconditions,when the temper-
ature around the sprinkler approaches
its operating temperature, the cover
plate detaches. Continued heating of
theexposedsprinklercausesthe fusible
link to disengage, releasing the deflec-
torand sealing assembly. Water flowing
through the sprinkler orifice strikes the
deflector, forming a uniform spray pat-
tern to extinguish or control the fire.

7. INSTALLATION
WARNING: Viking sprinklersaremanu-
factured and tested to meet the rigid re-
quirements of the approving agency.
The sprinklers are designed to be in-
stalled in accordance with recognized
installation standards. Deviation from
the standards or any alteration to the
sprinkler or cover plate assembly after it
leaves the factory including, but not lim-
itedto: painting, plating, coating or mod-
ification, may render the sprinkler inop-
erative and will automatically nullify the
approval and any guarantee made by
The Viking Corporation.
A. Sprinklers must be installed in accor-
dance with the latest published stan-
dards of the National Fire Protection
Association, Factory Mutual, Loss Pre-
vention Council, Assemblee Pleniere,
Verband der Sachversicherer or other
similar organizations, and also with the
provisions of governmental codes, ordi-
nances, and standards whenever appli-
cable. Concealedsprinklers are decora-
tive sprinklers and may be considered
special purpose. Refer to the Authority
Having Jurisdiction prior to installation .
NOTE: Previous Model B-1 Cover Plate
Assembly Part Number 08310 may still be
used for ULC/UL installations .
B. Sprinklers must be handled with care.
Concealedsprinklers areprotected witha
plasticshell,whichshouldremaininplace
overthe sprinkler body during installation,
testing, and any time the sprinkler is han-
dled or shipped. The plastic protective
shellmustberemovedprior toplacing the
systeminservice. Seesection“I”belo w.
Prior to installation, sprinklers must be
stored in a cool, dry place in their origi-
nal shipping container. Never install
sprinklers that have been dropped,
damaged in any way, or exposed to
temperatures in excess of maximum
ambient temperature allowed. Such
sprinklers should be destroyed immedi-
ately .
C. Horizon®Mirage®Quick Response
ConcealedSprinklersmustbeinstalled
in neutral or negative pressure ple-
nums only.
D. U se care when locating sprinklers near
fixtures that can generate heat. Do not
installsprinklerswheretheywouldbeex-
posed to temperatures that exceed the
maximum recommended ambient tem-
peratureforthetemperatureratingused .
E. Horizon®Mirage ®Concealed Sprin-
klers are not intended for use in corro-
sive environments. Use only sprinklers
listed for corrosive environments when
subject to corrosive atmospheres.
F. Adequate heat must be provided when
Horizon ®Mirage®QuickResponse Ex-
tended Coverage Concealed Sprin-
klersare installedon wetpipe systems.
When installing sprinklers on dry sys-
tems, refer to appropriate installation
guides and the Authority Having
Jurisdiction.
G. Sprinklers must be installed after the
piping is in place to preventme chanical
damage. Before installation, be sure to
have the appropriate sprinkler model
and style, with the correct orifice size,
temperature rating, and response char-
acteristics. Install the sprinklers accord-
ing to the following steps :
1. Installallpipingand cutthe sprinkler
drop nipple to position the 1/2" or
3/4" (depending on the sprinkler)
NPT outlet of the reducing coupling
at the desired elevation. The drop
nipple must be perpendicular to the
ceilingand centeredin a2" (50mm)
diameter opening in the ceiling.
2. With the sprinkler in the plastic pro-
tectiveshell,applyasmallamountof
pipe-joint compound or tape to the
external threads of the sprinkler
only, taking care not to allow a
build-up inside the sprinkler inlet .
3. Use only the special wrenches de-
signed for installing Horizon ®Mirage ®
Concealed Sprinklers. With the sprin-
kler in the plastic protective shell,
place the unit into the wrench .
4. Turn the unit clockwise to thread the
sprinkler into the 1/2" or 3/4" (de-
pending on the sprinkler used) NPT
outlet of the coupling. DO NOT use
the fusible link to start or thread the
sprinkler into a fitting.
H.Afterinstallation,theentiresystemmust
be tested in accordance with recog-
nizedinstallationstandards.Thetestis
appliedaftersprinklerinstallationtoen-
sure that no damage has occurred to
thesprinklerduringshippingandinstal-
lation, and to make sure the unit has
beenproperlytightened.Ifathreadleak
occurs, normally the unit must be re-
moved, new pipe-joint compound or
tape applied, and then reinstalled. This
is due to the fact that when the joint seal
leaks, the sealing compound or tape is
washed out of the joint .
I. After testing, repairing of all leaks, and
installation and painting of the ceiling,
the cover plate assembly may be at-
tached.
