Reference Figure 2
Area Of Use:
Flat concealed spaces of solid wood
joist construction. The upper deck
and ceiling joists may have a maxi-
mum depth of 12 inches (300 mm)
and typical on center joist spacing of
minimum 16 inches (400 mm).
Concealed Space Area:
The area of the concealed space is
not limited, however blocking must
be provided in each upper deck and
ceiling joist channel at a maximum
32 feet (9.75 m) intervals. This block-
ing shall be installed to the full depth
of the joists and be constructed us-
ing a material which will not allow
heat to escape through or above the
blocking.
Concealed Space Size:
The minimum and maximum con-
cealed space depth is as follows:
The maximum depth of the con-
cealed space is 54 inches (1372
mm) from bottom of upper deck to
top of ceiling, and the minimum
depth is 6 inches (150 mm) from the
bottom of the upper deck joists to
the top of the ceiling joists.
System Type:
Light hazard, wet pipe system.
Minimum Distance Between CC1
Sprinklers:
6 feet (3.1 m).
Maximum Distance Between CC1
Sprinklers:
10 feet (3.1 m).
Maximum Coverage Area:
100 ft

(9.3 m2)
Deflector Position:
Upright and 1-1/2 to 2 inches (38 to
51 mm) below joists.
Remote Area:
1000 ft
