1. DESCRIPTION
Viking QR COIN
®
Sprinklers are quick response specific application sprinklers
for combustible interstitial (concealed) spaces (i.e., between floors, as well
as low pitch attics that meet the criteria shown in the figures in this data
page). These upright sprinklers are designed for use in specific light hazard
combustible, as well as non-combustible, concealed spaces requiring sprinkler
protection. The orifice design of the Viking QR COIN
®
Sprinkler, with a nominal
K-factor of 5.6 (80 metric*), allows efficient use of available water supplies for
hydraulically designed fire protection systems. The glass bulb operating element
and special deflector combine speed of operation and area of coverage to meet
the crucial fire protection requirement for shallow space combustible concealed
spaces. The Electroless Nickel PTFE (ENT) coating has been investigated for
installation in corrosive environments and is listed/approved as indicated in the
Approval Charts.
FEATURES
• In some cases COIN
®
Sprinklers can allow the use of CPVC piping within the
concealed spaces of applications requiring sprinkler protection in open truss
construction of both wood and steel trusses (see Figure 3) and solid wood or
composite wood joist with upper deck filled with non-combustible insulation
(see Figure 5).
• COIN
®
Sprinklers can also be installed with steel pipe in protected areas
constructed of solid wood joists (see Figure 7), and solid wood or composite
wood joist with upper deck filled with non-combustible insulation (see Figure 8),
and in unobstructed open truss construction of both wood and steel trusses
(see Figures 9 and 10) as well as obstructed wood truss construction (see
Figure 11).
• When using steel pipe, COIN
®
Sprinklers can be applied as a dry system
using air or gas as a supervisory medium (see Figures 7–11).
• In certain scenarios, draft curtains are
NOT
required when sprinkler spacing
meets either of the following criteria (also refer to Design Criteria):
-
14' X 14' (4,3 m X 4,3 m) for solid wood joists or trusses on edge
-
16' X 16' (4,9 m X 4,9 m) for truss construction on face (not on edge)
For examples of trusses on face or edge see Figures 13A and 13B.
2. LISTINGS AND APPROVALS
cULus Listed:
Category VNIV
Refer to the Approval Chart and Design Criteria in this technical data sheet for cULus Listing requirements that must be followed.
The COIN
®
Sprinkler has been tested to address the proper application density for shallow concealed combustible space fire
protection when installed in accordance with this technical data page. The COIN
®
Sprinkler must be installed in the upright position
as specified in the appropriate application described in Figures 3–12. The clearance from the sprinkler deflector to the roof is critical
to operation of the sprinkler (refer to Figures 3–12). The clearances from pipe to lower ceiling for CPVC pipe is critical for protection
of CPVC pipe.
For open truss and joist spaces, the maximum detection area is important for proper installation.
In certain installations, draft curtains or heat collection baffles or solid walls are
required
using wood or other product that
will not allow heat to escape. In these installations, the maximum detection space shall be
limited
to 1000 ft
2
(93 m
2
) or
2000 ft
2
(185 m
2
) for solid wood joists. The draft curtain is required to protrude down from the top deck surface as specified herein.
Additionally, draft curtains are
not
required and the maximum detection space shall be
unlimited
for open truss construction with
the top chord member on their face (not on edge) when sprinkler spacing is up to 16' X 16' (4,9 m X 4,9 m) and for solid wood
joists or trusses on edge when sprinkler spacing is up to 14' X 14' (4,3 m X 4,3 m). In these cases, draft curtains are
not required
.
