System Design
f(4 oô((
This section will cover the proper design of the Pyro Chem Res-
taurant Fire Suppression System. It is divided into four (4) sections:
Nozzle Coverage and Placement.
Cylinder Sizing.
Piping Limitations.
Detector Requirements.
Each of these sections must be completed before
attempting any installation.
SECTION 1
Nozzle Coverage and Placement
This section will provide guidelines for determining nozzle
type, positioning, and quantity for duct, plenum, and
appliance protection.
A. Duct Protection
The following three (3) nozzles have been developed for
the protection of exhaust ducts:
Model NL-R
Model NL-D2.
Model NL-D3.
Each nozzle is approved for use with the exhaust fan dampered,
undampered with -tfie fan on, or undampered with the fan off. It
is not required that the fan be shut down or the exhaust duct be
dampered for the system to operate properly. Each nozzle is
approved to protect exhaust ducts of unlimited length.
1. Model NL-P.
The Model NL-P nozzle is a one (1) flow point nozzle
designed for the protection of exhaust ducts. One (1) or
two (2) Model NL-P nozzles can be used on a single duct
branch.
A single Model NL-P exhaust duct nozzle can protect a square
or rectangular duct with a maximum perimeter of 50 inches
and a maximum one-side length of 17 inches. It can also
protect a round duct with a maximum circumference of 50
inches and a maximum diameter of 16 inches (see Figure 3-1).
The nozzle must be installed on the centerline of the duct and
aimed directly into the duct opening (see Figure 3-2).
Two (2) Model NL-P exhaust duct nozzles can protect a
square or rectangular duct with a maximum perimeter of
84 inches and a maximum one-side length of 34 inches.
They can also protect a round duct with a maximum
circumference of 84 inches and a maximum diameter of
26.5 inches. When two (2) Model NL-P nozzles are used to
protect a single duct, the cross sectional area of the duct
must be divided into two equal symmetrical areas. The
nozzle must then be installed on the center line of the area
it protects and aimed directly into the duct opening (see
Figure 3-2.1).
Model NL-D2.
The Model NL-D2 nozzle is a two (2) flow point nozzle
designed for the protection of exhaust ducts. Only one (1)
Model NL-D2 nozzle can be used on a single duct branch.
A single Model NL-D2 exhaust duct nozzle can protect a
square or rectangular duct with a maximum perimeter of
75.5 inches and a maximum one-side length of 25 inches.
It can also protect a round duct with a maximum circum-
ference of 75.5 inches and a maximum diameter of 24
inches (see Figure 3-1). The nozzle must be installed on
the centerline of the duct and aimed directly into the duct
opening (see Figure 3-2).
Model NL-D3.
The Model NL-D3 nozzle is a three (3) flow point nozzle
designed for the protection of exhaust ducts. One (1) or two
(2) Model NL-D3 nozzles can be used on a single duct branch.
A single Model NL-D3 exhaust duct nozzle can protect a
square or rectangular duct with a maximum perimeter of
100 inches and a maximum one-side length of 33 inches.
It can also protect a round duct with a maximum circum-
ference of 100 inches and a maximum diameter of 31.75
inches (see Figure 3-1)
The nozzle must be installed on the centerline of the duct
and aimed directly into the duct opening (see Figure 3-2).
Two (2) Model NL-D3 exhaust duct nozzles can protect a
square or rectangular duct with a maximum perimeter of 150
inches and a maximum one-side length of 66 inches. They
can also protect a round duct with a maximum circumference
of 150 inches and a maximum diameter of 47.5 inches. When
two (2) Model NL-D3 nozzles are used to protect a single duct,
the cross sectional area of the duct must be divided into two
equal symmetrical areas. The nozzle must then be installed
on the centerline of the area it protects and aimed directly
into the duct opening (see Figure 3-2.1).

B. Plenum Protection
The Model NL-A nozzle is a one (1) flow point nozzle that 61 MAX
XX' MAX has been developed to protect the plenum section of the
exhaust hood. Only one (1) Model NL-A nozzle can be
used on a single plenum branch. A single Model NL-A can
protect a plenum (with single or V-Bank filters) with
rectangular dimensions of 8 x 4' or less. Larger plenums
can be protected by dividing the hazard area so that each
nozzle protects an area of 8' x 4 or less (see Figure 3-3).
The nozzle(s) must be located at the center of the V-Bank
width or centered between the filter width when used with
a single bank filter plenum. It must be within 4 of the wall
it is mounted against (see Figure 3-4), or within 4" of the
edge of the protected zone.

Pyro Chem has developed two new nozzles for protecting range tops. They may be
used in addition to the range top' protection currently q.iaIified for the PCL-Series
systems.
A. The Model NL-RH2 is a two (2) flow point nozzle that can be used for range top
protection. The maximum range top area that can be protected by a single NL-RH2
nozzle is 28" by 28. The nozzle must be located within 5 of the center of the
protected zone and aimed at the center of the protected zone. The nozzle must be
mounted 32 to 45 above the cooking surface.

Enclosed with this bulletin is Revision 2 of Page 3-4a and Page 3-4b of the Technical
Manual which illustrates this coverage. This new page can be inserted in the Technical
Manual for easy reference by removing and discarding Revision 1 of Page 3-4a. All
other system parameters and limitations are listed in the Technical Manual.
Nqte: Any branch that utilizes the NL-RH2 for range top protection must comply with
the limitations listed in the Technical Manual for an Appliance Branch of the appropriate
number of nozzles on the branch (one; two, or three). Four nozzle range branch piping

Two types of chain broilers are commonly used; open and

a. Closed Top Chain Broiler Coverage.
The Model NL-UB nozzle is a one-half (V2) flow point
nozzle that is used for closed top chain broiler protection.
Two (2) Model NL-UB nozzles are commonly used for this
application. The purpose of using two nozzles is to
distribute the chemical evenly between the cooking
surface (on top) and the drip pan (below). For closed top
chain broilers that have no drip pan, a single Model NL-
UB nozzle can be used. The maximum area that can be
protected by a pair of NL-UB nozzles (or a single NL-UB
nozzle when no drip pan is present) is 30" x 34".
One nozzle must be positioned in the front entrance of the
broiling chamber and aimed at the diagonal corner. The
nozzle will be positioned above the cooking surface. The
