DESIGN CRITERI
A - STEEL PIPE
(See Figures 7
–
12)
(Also refer to the Approval Chart on page 3)
The Viking COIN
®
Sprinkler MUST be installed in the upright position.
APPLICATION
For installation in horizontal concealed spaces of solid wood joist construction with a roof pitch of up to 2/12 maximum. The upper joist is constructed
of solid wood or composite wood with a maximum depth of 12” (300 mm) and 16” (400 mm) on center minimum spacing. Also, steel pipe may be ap-
plied in truss construction and solid filled non-combustible insulation in upper deck and wood or composite joist construction similar to that shown in
Figures 3-5 with the exception of extra sprinklers are not required over obstructions. Also, there is no minimum clearance for supply pipe to upper joists.
With the COIN
®
Sprinkler applied using steel pipe, the system may be wet, dry, or preaction type for wood truss or steel construction; solid wood or
composite with non-combustible solid fill insulation (see Paragraph J on page 9).
NOTE:
In order to be considered “non-combustible insulation filled solid wood or composite wood joist construction”, the insulation (including insulation
provided with a combustible vapor barrier), must completely fill the pockets between the joists to the bottom of the joists, and the insulation must be
secured in place with metal wire netting. The metal wire netting is intended to hold the insulation in place should the insulation become wetted by the
operation of the COIN
®
Sprinklers in the event of a fire.
A. Concealed Space Limitations
The total concealed space is not limited; however, the following must be observed:
•
Blocking between joists and upper deck must be constructed of material that will not allow heat to escape through or above the blocking.
•
The blocking must be constructed to the full depth of the upper joist, and must be constructed using a non-combustible material or a material that
is the same as that of the joist construction. A maximum channel space for blocking is 32 ft (10 m) intervals.
•
Solid wall construction or draft curtains (heat collection baffles) must protrude below the joist a minimum of 6” (150 mm) or 1/3 the space, whichever
is greatest, and run laterally with the joist spaced at 31 ft (9.4 m) width maximum to limit the heat detection space to a maximum of 1,000 ft
2
(93 m
2
)
or with the truss spaced at 62 ft (19 m) width maximum to limit the heat detection space for open wood truss construction to 2000 ft
2
(185 m
2
) with
their top chord members on face (not on edge) and 2000 ft
2
(185 m
2
) for solid wood joists.
•
Insulated top chord spaces (on edge) confine heat localized detection area to 2000 ft
2
(185 m
2
), non-insulated top chord spaces on edge confine
heat localized area to 1,000 ft
2
(93 m
2
).
•
The draft curtain may be constructed of ¼” (6 mm) thick plywood to prevent heat from escaping beyond.
•
When non-combustible solid filled insulation is used, the wood blocking and draft curtains are not required for solid wood or composite wood joist
construction.
•
Draft curtains are NOT required when sprinkler spacing is up to 14' X 14' (4,3 m X 4,3 m) for solid wood joists or trusses on edge for wet systems
only; see Figure 13B.
•
Draft curtains are NOT required when sprinkler spacing is up to 16' X 16' (4,9 m X 4,9 m) for truss construction on face (not on edge) for wet or dry
systems; see Figure 13A.
•
Draft curtains are NOT required when using wood truss construction with chords on face and non-combustible insulation is provided to the bottom of
the trusses (Figure 12).
B. Concealed Space Height
Solid Wood or Composite Wood Joist Construction (See Figures 7 and 8):
•
Maximum depth or height of concealed space: 60” (1500 mm) from bottom of upper deck joist to top of ceiling joist.
•
Maximum space from bottom of upper deck to ceiling surface (bottom of joist): 84” (2100 mm). See Figure 7.
•
Minimum depth or height of concealed space: 6” (150 mm) from bottom of upper deck joist to top of ceiling frame joist.
Open Wood Truss or Open Web Steel Joist (See Figure 10):
•
Maximum height from inside ceiling to inside deck of concealed space: 60” (1500 mm).
•
Minimum height from bottom of upper chords to top of lower chords: 6” (150 mm)
•
The top and bottom chord members of these types of wood joists must be on face (not on edge).
Obstructed Wood Truss (See Figure 11):
•
Maximum depth of concealed space: 84” (2100 mm) from bottom of upper deck to top of ceiling.
•
Minimum depth of concealed space: 6” (150 mm) from bottom of upper chord to top of lower chord.
C. System Type
•
Light hazard, wet pipe system or dry pipe system supervised with air or gas when using steel pipe only.
D. Minimum Density

Sprinkler Deflector Position
The COIN
®
Sprinkler shall be installed in the upright position. The frame arms must be installed parallel with the pipe.
•
1-1/2” to 2” (40 - 50 mm) below solid wood joist or top chord of obstructed wood truss construction. See Figures 7 and 11.
•
1-1/2” to 4” (40 - 100 mm) below upper deck for unobstructed open wood truss construction or concealed spaces of non-combustible open steel joist
construction. See Figures 8 and 9.
•
1-1/2” to 4” (40 - 100 mm) below non-combustible insulation-filled solid wood joists or composite wood joists. See Figure 8.
