Note the minimum distance between sprinklers changes
by the angle of the slope. Verify the Listed flows and
pressures for “maximum” and “
1
⁄
2
maximum” distances.
Dimensions “A” and “B” are measured along the slope. For
angles greater than 60
°
, verify with Central's Technical
Services Department.
A — NFPA minimum of 4" (verify “G” dimension minimum of
4"), maximum
1
⁄
2
of the Listed spacing that the sprinkler
was calculated for. (i.e., 18' x 18' spacing is maximum
of 9'-0" from a wall).
B — For angles 0
°
to 39
°
minimum B = 8'-0".
For angles 40
°
to 45
°
minimum B = 9'-0".
For angles 46
°
to 60
°
minimum B = 9'-6".
Maximum Listed spacing that the sprinkler was calcu-
lated for.
C — Maximum of 3'-0" vertically from the peak.
F — Acceptable for angles 0
°
to 60
°
.
G — Minimum of 4", for maximum, refer to “A” and measure
along slope.
The minimum distance between sprinklers on opposing
slopes is measured horizontally, some difficult conditions
can be solved by staggering the sprinklers, thus increasing
the horizontal distance. Remember to measure along the
slope for “A” and “B”. For angles greater than 60
°
, verify
with Central's Technical Services Department.
A — NFPA minimum of 4", maximum
1
⁄
2
of the Listed
spacing that the sprinkler was calculated for.
B — See “E” for minimum spacing. Maximum Listed
spacing that the sprinkler was calculated for.
C — Maximum 3'-0" vertically from the peak.
E — NFPA minimum of 8'-0" (when minimum of 8'-0"
cannot be obtained due to “B”, a baffle must be
installed between these sprinklers to obstruct the
discharge and prevent cold-solder). See “B” for
maximum.
F — Acceptable for angles 0
°
to 60
°
.
* For unequal spacing down from peak, see Figure 4.
