3-15.2.1 Nozzle Placement
There are certain coverage and height limitations which must be observed with each nozzle
configuration to ensure proper Agent distribution.
Figure 3-5. Nozzle Placement and Coverage
• Orientation-Nozzles must be mounted perpendicular to the ceiling or subfloor surface and
oriented with the orifices radiating outward from the pipe network. Pendant or upright
mounting of the nozzle is acceptable.
Figure 3-6. Nozzle Orientation
• Ceiling Clearance-Nozzles must be installed so that the orifices are located 6 to 12 in (152
to 305 mm) below the ceiling. In enclosures using the minimum ceiling height (1 ft), the
nozzles must be installed so that the orifices are located 6 in +/- 2 in (152 +/- 51 mm)
below the ceiling.
• Maximum Height-The maximum protected height for a single row of nozzles is 16.0 ft
(4.88m). Nozzles may be tiered to accommodate enclosures with ceiling heights greater
than 16.4 feet (5 m), but no greater than 32 ft (9.8 m).
• Minimum Ceiling Height-The minimum ceiling height is 1 ft or 12 in (0.3 m).
• 180° Nozzles-180° nozzles must be located 6 +/- 2 inches (0.15 +/- 0.05 m) from
a wall, with the orifices directed away from the wall. The nozzle shall be located as
close to the center of the wall as possible, but at least 1/3 of the way along the wall.
180° nozzles have a maximum coverage area defined as a square that can be inscribed in
a semicircle of distance 39.8 ft (12.1 m, diagonal of a rectangle 17.8 ft x 35.6 ft). Refer to
Figure 3-5 for further information. 180° nozzles may be used in a back-to-back configura-
tion. The nozzles should be placed 1 to 2 ft (0.3 m to 0.6 m) apart.
