3: PRODUCT DESCRIPTION
The Viking Model M Quick Response
Dry Upright Sprinkler is an assembly
consisting of a thermo-sensitive glass
bulb spray sprinkler permanently se-
cured to a special supply nipple.
The Upright Sprinkler frame and deflec-
tor are of the Model M design, equipped
with a rugged 3 mm glass bulb that
meets the response criteria for Quick
Response sprinklers. The sprinkler is
available in several temperature ratings
to meet design requirements.
The special supply nipple is designed to
prevent water from entering the nipple
before the sprinkler operates. This fea-
ture makes the Dry Upright Sprinkler
suitable for use in unheated spaces
above ceilings of heated rooms
equipped with wet sprinkler systems.
Model M Quick Response Dry Upright
Sprinklers may be installed on wet sys-
tems, dry systems, or preaction sys-
tems.
A chrome escutcheon is provided with
each sprinkler, to cover the ceiling pene-
tration (see Figure 1). Model M Dry Up-
right Sprinklers feature a sealed brass
inlet and a durable threaded steel barrel
with an Electrodeposited Epoxy Base
coating.
The seal at the threaded end of the
assembly is held in place by force trans-
mitted from the compression screw,
through the glass bulb and internal parts,
onto a special sealing spring. During fire
conditions, the heat sensitive liquid in
the glass bulb expands, causing the
glass to shatter, releasing the internal
parts to open the waterway. Water flowing
through the sprinkler orifice strikes the
sprinkler deflector forming a uniform spray
pattern to extinguish or control the fire.
Viking Dry Upright Sprinklers may be or-
dered, in 1/2" (12,7mm) increments, in
lengths ("B" dimension) from 4-1/2"
(114,3mm) to 49-1/2" (1257,3mm) long
