SYSTEM DESIGN
The ANSUL R-102 Restaurant Fire Suppression System may be
used on a number of different types of restaurant cooking appli-
ances and hood and duct configurations. The design information
listed in this section deals with the limitations and parameters of
this pre-engineered system. Those individuals responsible for the
design of the R-102 system must be trained and hold a. current
ANSUL certificate in an R-102 training. program.
The R-102 and the PIRANHA systems use compatible agents and
components, therefore, they may be used together for cooking
appliance, hood, and duct protection. The primary ANSUL
AUTOMAN Release can be either. an R-102 or a PIRANHA ANSUL AUTOMAN Release and can actuate up to two additional
R-102 or. PIRANHA Regulated Actuators. In systems utilizing a
101 remote release, any combination of the maximum number of
regulated actuators can be used.
Both systems must actuate simultaneously.
Each system must be designed and installed per its apprOpri-
ate manual.
Adjacent appliances requiring protection must be protected
With the same type of system, either R-102 or PIRANHA,
unless the center-to-center spacing between the adjacent
R-102 and PIRANHA flozzles is no less than 36 inches.
When appliances are protected with R-102 nozzles, the hood
and connecting duct above those appliances cannot be pro-
tected with PIRANHA nozzles.
Mixing systems in a common plenum IS not allowed.
One of the key elements for restaurant fire protection is a correct
system design. This section is divided into ten sub-sections: Noz-
zle Placement Requirements, Tank Quantity Requirements, Actu-
ation and Expellant Gas Line Requirements, Distribution Piping
Requirements, Detection System Requirements, Manual Pull Sta-
tion Requirements, Mechanical Gas Valve Requirements, Electri-
cal Gas Valve Requirements, Electrical Switch Requirements, and
Pressure Switch Requirementè. Each of these sections must be
completed before attempting any installation. System design
sketches should be made of all aspects of design for reference
during installation.
NOZZLE PLACEMENT REQUIREMENTS
This section gives guidelines for nozzle type, positioning, and
quantity for duct, plenum, and individual appliance protection. This
section must be completed before determining tank quantity and
piping requirements.
Duct Protection - Single Nozzle
All duct protection is UL listed without limitation of maximum duct
length (unlimited length). This includes all varieties of ductworks
both horizontal and vertical including ducts that run at angles. to
the horizontal and ducts with directional. bends.
The R-102 system uses different duct nozzles depending On the
size of duct being protected.
GENERAL INFORMATION
1. Nozzles must be located 2-8 in. (5-20 cm) into the center of the
duct opening, discharging up. See Figure 1.
2-8 IN. (5-20 cm)
FIGURE 1
00cm In installatiOns where a UL. listed damper assembly is
employed, the duct nozzle can be installed beyond the 8 in.
(20 cm) maximum, to a point just beyond the damper assem-
bly that will not interfere with the damper. Exceeding the maxi-
mum of 8 in. (20 cm) in this way will not void the UL listing of
the system.
.Previously listed 3 flow number and 5 flow number duct pro-
tection detailed in earlier published manual, Part No. 418087-
06, can also still by utilized.

is limited to a maximum of 75 in. (190 cm) perimeter or a maxi-

Plenum Protection.
The R-102 system uses the 1W Nozzle (Part No. 419336) or the
IN Nozzle (Part No. 419335) for plenum protection. The 1W noz-
zle tip is stamped with 1W and the I nozzle tip is stamped with
iN, indicating they are one-flow nozzles and must be counted as
one flow number each. When protecting a plenum chamber, the
entire chamber must be protected regardless of filter length.
VERTICAL PROTECTION - GENERAL
One 1W nozzle will protect 4 linear feet (1.2 m) of plenum. The
maximum distance from the end of the hood to the first and last
nozzle must be no more than 2 ft. (.6 m). After the first nozzle, any
additional nozzles must be positioned at a:maximum of 4 ft. (1.2 m)
apart down the entire length of the plenum. The plenum width must
not exceed 4 ft. (1.2 m). (The 1W nozzle can be used on single or
V-bank filter arrangements.) See Figure 6.
Option 2: The 1W nozzle must be placed perpendicular, 8-12 in.
(20-30 cm) from the face of the filter and angled to the
center of the filter. The nozzle tip must be within 2 in.
(5 cm) from the perpendicular center line of the filter.

Gas-Radiant/Electric Char-Broiler Protection
The R-102 system uses the 1 N nozzle, (Part No. 419335) for gas-
' radiant/electric char-broiler protection.
The nozzle tip on the 1 nozzle is stamped with a IN, indicating
that this is a one-flow nozzle and must be counted as one flow
number.
One IN nozzle will proteât a hazard with a maximum length of
36 in. (91 cm) and a total cooking area which does not exceed
864 sq. in. (5574 sq. cm). The nozzle tip must be located 15 to
40 in. (38 to 102 cm) above the hazard surface. When using this
o. nozzle for gas-radiant/electric char-broiler protection, the nozzle
must be positioned anywhere along or within the perimeter of the
maximum cooking area and shall be aimed at the center of the
cooking surface. See Figure 51.

DISTRIBUTION PIPING REQUIREMENTS (Continued)
Distribution Piping Requirements —1.5 Gallon System
DUCT, PLENUM, AND APPLIANCE PROTECTION
This option allows for duct protection, plenum protection,
appliance protection, or any combination.
When using a combination of plenum and duct protection only, only one duct nozzle, either a 1W, or a 2W, may be used.
The previous Option 2 (using 2WH nozzle for plenum and duct
protection) still can be utilized. For detailed design information,
see previous version of this manual, Part No. 418087-06.
Note: When using this option, all design parameters must:be
followed as listed in manual version -06.
All distribution piping, supply and branch, must be 3/8 in.
Schedule 40 black iron, chrome-plated, or stainless steel.
Each 1.5 gallon tank allows a maximum of five flow numbers.* a.
The pipe length between the start of the first branch line and the start of the last branch line must not exceed 8 ft. (2.4 m).
When the supply line is split, the combined length of both
legs of the supply line (start of first branch line to start of last branch line) must not exceed 8 ft. (2.4 m). See Figure 91.
The combined length of all branch lines must not exceed 22 ft..
(6.7 m). See Figure 92.

DISTRIBUTION PIPINGREQUIREMENTS (Continued)
Distribution Piping Requirements -9.0 Gallon System
This optional configuration consists only of three 3-gallon tanks, all pressurized from a single double-tank nitrogen cartridge with expellant gas hoses connected as shown in Figure 97. Tanks No. 1 and No.2 must be connected directly to the regulator with sepa-rate expellant gas hoses and Tank No. 3 must be connected to 'Tank No.2 with a third expellant gas hose as shown in Figure 97. Each tank must be connected to an independent distribution pip-
sing network as shown in Figure 97. Distribution piping require-
ments for each network must be as follows:
The maximum length between the start of the first branch line and the start of the last branch line must not exceed 24 ft. (7.3 m). When the supply line is split the combined total of
both legs of the supply line (from the start of the first branch line to the start of the last branch tine) must not exceed 24 ft.
' (7.3 m). See Figure 93.
The total length of all branch lines must not exceed 36 ft.
' (10.9 m). See-Figure 93.
Use a 3/8 in. union to connect the tank adaptor to the 3/8 in. supply line.
A maximum of two nozzles are allowed per duct branch line.
When using this 9.0 gallon system configuration, no nianl-
folding of distribution piping is allowed.
When an ANSUL AUTOMAN RégulatedRelease is utilized in
this configuration, additional regulator actuators cannot be
used.
Only 3 gallon tanks can be utilized In- this configuration.
The requirements of the following table must not be exceeded.
