SYSTEM DESIGN
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 nozzles 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.
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.
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 Requirements. 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 plenum, duct, and individual appliance protection. This
section must be completed before determining tank quantity and
piping requirements.
Duct Protection
All duct protection is UL approved without limitation of maximum
duct length (unlimited length). This includes all varieties of duct-
works both horizontal and vertical including ducts that run at
angles to the horizontal and ducts with directional bends.
The R-102 system uses several different duct nozzles depending
on the size of duct being protected.
1. 1 W Nozzle (Part No. 419336) — 1.5 Gallon and 3.0 Gallon
Systems:
The R-102 systems, both 1.5 gallon and 3.0 gallon, use the
1 W nozzle (Part No. 419336) for duct protection of 27 in.
68.6 cm) perimeter or less or 8.5 in. (21.6 cm) diameter or
less. The nozzle tip is stamped with 1 W, indicating that this is
a one -flow nozzle and is to be counted as one flow number.

9. Multiple -Nozzle Duct Protection:
For ducts larger than 150 in. (254 cm) perimeter, the total
perimeter of the duct must be divided by 75. If the answer con-
tains a decimal (or fraction), it must be rounded -up to the near-
est whole number. This answer signifies the number of equal-
ly -sized modules in which the duct must be divided. The diag-
onal dimension of each module must not exceed 35.5 in.
90.2 cm). If diagonal dimension is exceeded, additional mod-
ule divisions must be added until the diagonal dimension is not
exceeded. A nozzle must then be centered in each module.
Example: Figure 20 shows a duct opening of 270 in.
686 cm) perimeter. By dividing 270 in. (686 cm) by
75, it is determined that the duct must be divided
into 4 equally -sized modules. Because the diago-
nal dimension of each module is 33.54 in.
85.2 cm), it is within the maximum limit of 35.5 in.
90.2 cm) and therefore acceptable as shown in
Figure 21. One nozzle is then centered in each
module as shown in Figure 22.

Electrostatic Precipitator Protection
Some restaurant ventilating ducts have an electrostatic precipita-
tor installed at or near the base. These precipitators are used to
aid in the cleaning of exhaust air.
Normally electrostatic precipitators do not require protection but
should the "authority having jurisdiction" require protection, use
the following guidelines.
Ducts with precipitators located at or near the base can be pro-
tected using duct nozzle(s) above the precipitator and 1/2N noz-
zle(s) (Part No. 419334) for the precipitator. One 1/2N nozzle must
be used for each cell being protected. This nozzle tip is stamped
with 1/2N, indicating that it is a 1/2-flow nozzle and must be count-
ed as 1/2 flow number.
When protecting ducts equipped with precipitators, the duct noz-
zle(s) must be installed above the precipitator and aimed to dis-
charge downstream. If the area above the precipitator is a duct:
the nozzle(s) must be positioned according to duct protection
guidelines. If the area above the precipitator is a transition, the
transition guidelines must be followed. See Figure 20.

Fryer — Multiple Nozzle Protection
Design Requirements:
Fryers exceeding the coverage of a single nozzle can be divided
into modules. Each module must not exceed the maximum area
allowed for a single nozzle. However, when utilizing multiple
nozzle protection, the longest side allowed for a fryer with drip -
board can be used, regardless of whether the fryer has a drip -
board or not.
The maximum size fryer that can be modularized is 864 sq. in.
5574 sq. cm) or in terms of ft.. 6 sq. ft. (1.8 m).
1. Design requirements for multiple nozzle fryers are broken
down into two types:
A. FRYERS WITHOUT DRIPBOARD(S)
If the fryer does not include a dripboard, measure the inter-
nal depth (horizontal dimension from front to back) and
length of the frypot. Then, multiply the depth and length to
obtain the area of the frypot in square inches.
B. FRYERS WITH DRIPBOARD(S)
If the fryer includes any dripboard areas, measure both the
internal depth and length of the frypot portion, and then
measure the internal depth and length of the overall hazard
area including any dripboard areas.
Determine the area of both the frypot and the area of the
overall vat by multiplying corresponding depth and length
dimensions.
2. Divide the frypot or overall vat into modules, each of which
can be protected by a single nozzle, based on the maximum
dimension and area coverage of the nozzle as specified in
Table, "Maximum Cooking Area Dimension — Multiple Nozzle
Protection."
A. If the module considered does not include any portion of
the dripboard, use only the maximum frypot area and max-
imum dimension listed in the first column of the table to
select the correct nozzle.
B. If the module considered includes any dripboard areas, use
both the maximum frypot area and dimension listed in the
first column of the table, and the maximum overall area and
dimensions listed in the second column of the table to
select the correct nozzle.
3. None of the maximum dimensions in either column may be
exceeded. If either the maximum frypot or the overall sizes are
exceeded, the area divided into modules will need to be rede-
fined with the possibility of an additional nozzle.
Options For Modularizing Fryers
The following Figure 36 shows approved methods of dividing
modularizing) fryers so that each section can be properly protect-
ed.

Example: A fryer with a dripboard. The inside vat without the drip -
board measures 18 in, in depth x 30 in. in length (46 cm. x 76 cm)
and the inside of the overall vat including the dripboard measures
24 in. in depth x 30 in. in length (61 cm x 76 cm). Because the fryer
is 30 in. (76 cm) in length, it exceeds the coverage of a single.
nozzle.
Dividing the length in half, each module now has an overall vat
dimension of 24 in. in depth x 15 in. in length (61 x 38 cm). From
the Table, "Maximum Cooking Area Dimension — Multiple Nozzle
Fryer Protection, " either the 3N or the 290 nozzle should be select-
ed to protect each fryer module, depending on the maximum noz-
zle height above the fryer and the positioning requirements
allowed. Refer to appropriate Figures, 31 through 35,

Multiple Nozzle Fryer Protection — Tilt Skillet / Braising Pan
Protection for tilt skillets or braising pans is to be based upon the
coverage limitations provided for deep fat fryer protection. Refer to
Section IV, DESIGN, starting on Page 4-9, for maximum fryer noz-
zle coverages and maximum fryer nozzle height limitations.
Although the maximum 6 sq. ft. total surface cooking area require-
ment applies to fryer protection, it does not apply to tilt skillets or
braising pans.
Each tilt skillet/braising pan protected module must not exceed the
fryer limitations for "MAXIMUM SIZE MODULE OVERALL WITH
DRIPBOARD" coverage per nozzle as described in Table on Page
4-13.
Tilt skillets and braising pans generally utilize a hinged cover.
Fryer protection nozzles are to be placed toward the front of the
appliance to minimize the potential for the tilt skillet or braising pan
cover to interfere with the nozzle discharge. See Figure 41.
THE NOZZLE IS TO BE PLACED TOWARD THE FRONT OF THE APPLIANCE TO MINIMIZE

Chain Broiler Protection
The R-102 system uses two 1N Nozzles (Part No. 419335) for
chain broiler protection. The nozzle tip is stamped 1 N, indicating
that this is a one -flow nozzle and must be counted as one flow
number (total of two flow numbers for each chain broiler being pro-
tected).
Two 1 N nozzles are always needed for chain broiler protection
when the hazard area to be protected does not meet the
Overhead Broiler Protection" requirements. The maximum inter-
nal size of the broiler is 43 x 31 in. (109 cm x 79 cm). The nozzles
must be positioned at each end of the enclosed cooking chamber
1 to 3 in. (2.5 to 7.5 cm) above the surface of the chain and a max-
imum distance of 4 in. (10 cm) away from the broiler opening. The
nozzles may be mounted at either corner as long as they are at
opposite ends of the chain broiler and positioned to disch#lrge
diagonally across the top of the chain. See Figures 58 and A

Overhead Chain Broiler Protection
The R-102 system uses two 1 W Nozzles (Part No. 419336) for
overhead chain broiler protection. The nozzle tip is stamped with
1 W, indicating that this is a one -flow nozzle and must be counted
as one flow number.
Overhead protection is only available for chain broilers with
exhaust opening dimensions that are not less than 60% of the
internal broiler length and not less than 60% of the internal broiler
width, to a minimum size of 12 in. z 12 in. (30.5 x 30.5 cm). Internal
broiler size can not be larger than 32 in. x 34 in. (81 x 86 cm).
When overhead protection is used, the nozzles must be centered
above the exhaust opening within 4 to 8 in. (10 to 20 cm) of each
other and they must be located 10 to 26 in. (25 to 66 cm) above
the top of the broiler surface. See Figure 60,

Overhead Chain Broiler Protection (Continued)
Example No. 1 - Internal broiler size is 24 in. long x 20 in. wide
61 x 51 cm), with an opening of 16 in. x 16 in.
40.6 x 40.6 cm).
To determine minimum opening size, multiply the
internal length and the internal width by 0.6:
Length of opening - 24 in. x 0.6 = 14.4 in.
61 cm x 0.6 = 36.6 cm)
Width of opening - 20 in. x 0.6 = 12.0 in.
51 cm x 0.6 = 30.5 cm)
The minimum allowable opening for overhead protec-
tion would be 14.4 in. x 12.0 in. (36.6 x 30.5 cm).
This example would be acceptable for overhead pro-
tection.
Example No. 2 - Internal broiler size is 30 in. long x 24 in. wide
76 x 61 cm) with an opening of 22 in. x 12 in.
56 x 30 cm).
To determine minimum opening size, multiply internal
length and internal width by 0.6:
Length of opening - 30 in. x 0.6 = 18.0 in.
76 cm x 0.6 = 45.7 cm)
Width of opening - 24 in. x 0.6 = 14.4 in.
61 cm x 0.6 = 36.6 cm)
Minimum allowable opening for overhead protection
would be 18 in. x 14.4 in. (45.7 x 36.6 cm).
Because this broiler has an opening of 22 in. x 12 in.,
the 12 in. width is below the minimum allowable cal-
culated dimension of 14.4 in. (36.6 cm) and therefore
would not be acceptable for overhead protection.
Upright/Salamander Broiler Protection
The R-102 system uses two 1/2N Nozzles (Part No. 419334) for
all upright/salamander broiler protection. The nozzle tip is stamped
1/2N, indicating that this is a half -flow nozzle. A pair of these noz-
zles will equal one flow number.
N. Two 1/2N nozzles will protect a maximum hazard area (internal
broiler chamber) of 30 in. x 32.5 in. (76 cm x 82.5 cm). These noz-
zles must always be used in pairs on an upright/salamander broil-
er. One nozzle must be positioned above the grate and pointed at
the back opposite corner of the broiler chamber. The second noz-
zle must be pointed down into the center of the drip pan through
the open slot. See Figure 62.

DETECTION SYSTEM REQUIREMENTS
Once the fire suppression system design has been determined, a
detection system design must be completed. This section contains
guidelines and limitations for detection system installation.
Detector Identification
The two types of detectors are distinguished from each other by
their location in the detection system.
1 The Terminal Detector (Part No. 56838, 15375, or 417368) is
the last in a series of detectors, or the only detector used in a
single -detector system. This detector is thus named because
it is at the point at which the wire rope ends, or "terminates."
2. A Series Detector (Part No. 56837, 15373, or 417369) is any
detector located in -line between the regulated release mech-
anism and the terminal detector.
Detector/Pulley Elbow Quantity
The quantity of detectors used in the system will vary depending
on the style of detector used.
1. Conduit runs, pulley elbows, and number of detectors per sys-
tem must be within the approved system guidelines. The fol-
lowing requirements must not be exceeded:
Maximum Maximum Maximum
Number of Number of Length of 1/2
Detectors Elbows in. Conduit
per System per System per System
Clip on Style 12 18 125 ft. (38.1 m)
Detector
Hinge Style 5 8 103 ft. (31.3 m)
Detector
Scissors Style 15 20 150 ft. (45.7 m)
Detector
2. If hinge style detectors are mixed in a system with either clip -
on or scissor style, 4 series and 1 terminal is the maximum
number allowed. If clip -on style are mixed with scissor style,
the maximum allowed is 11 series and 1 terminal.
NOTICE
When using the "clip -on" style detector, the ter-
minal detector may use the "hinged" style
mounting bracket with the "clip -on" style linkage.
This is only allowed with the terminal detector.
When using this option, the total number of "clip -
on" style detectors (11 series and 1 terminal) is
still allowed.
3 If hinge style detectors are mixed in a system with either clip -
on or scissor style, the maximum length of wire rope must not
exceed 103 ft. (31.4 m) and the maximum number of pulley
elbows must not exceed 8. If clip -on style are mixed with scis-
sor style, the maximum length of wire rope must not exceed
125 ft. (3.81 m) and the maximum number of pulley elbows
must not exceed 18.
4. If the hazard requires more than 15 detectors, up to five 101
Remote Releases (Part No. 12029) can be used for system
actuation. Each 101 remote release allows the use of a maxi-
mum of 15 "scissor" style detectors (14 series and 1 terminal)
for a total of 75 detectors if needed.
SECTION IV — SYSTEM DESIGN
UL EX, 3470 ULC CEx747 Page 4-45

Detector Placement Requirements
EXHAUST DUCTS
Each exhaust duct must have at least one detector installed in the
duct entrance, located in the airstream of the cooking vapors, or at
a maximum of 20 ft. (6.1 m) into the duct opening. See Figure 93.
FIGURE 93
0002).
NOTICE
When gas appliances are used and the flue
gases from the burner are exhausted into the
duct, the detector must be kept out of the air
stream of these exhaust gases. These gases
can be very hot and could actuate the system
unnecessarily.
Duct openings that are long and narrow or large
enough to require multiple duct nozzles may
require additional detectors.
ELECTROSTATIC PRECIPITATOR
If an electrostatic precipitator is located at or near the base of the
exhaust duct, it is necessary to locate a detector below the pre-
cipitator, at the base of the duct, and also locate one in the duct.
just above the precipitator. See Figure 94.
When installing the detector bracket and system conduit, make
certain they do not interfere with the operation of the precipitator.

DETECTOR SYSTEM REQUIREMENTS (Continued)
Detector Replacement Requirements (Continued)
COOKING APPLIANCES
If the cooking appliance is located under an exhaust duct where a
detector has been mounted, it is normally not necessary to utilize
another detector for that cooking appliance, provided the detector
is not more than 12 in. (30 cm) into the duct. See Figure 95.

FIGURE 95
000269
Detectors used for cooking appliances must be located above the
surface and within the perimeter of the cooking appliance. They
must be positioned toward the exhaust duct side of the appliance
and high enough to prevent accidental actuation of the system.
The cooking appliance detectors must be located in the air stream
of the cooking fumes for quick fire detection. It is normally neces-
sary to use one detector per area of single nozzle coverage, even
though more than one appliance may be covered with a single
nozzle.
Detection Line Requirements
CONDUIT
Rigid conduit, 112 inch Schedule 40 galvanized pipe, or 1/2 inch
EMT thin -wall conduit may be used. Standard steel conduit fittings
compression type are recommended) must be employed to prop-
erly install the detection system. All conduit or pipe must be firmly
supported. When using pipe, make certain that all ends are care-
fully reamed, deburred and blown clear of chips and scale before
assembly.
NOTICE
The conduit offset can be used at the top or bot-
tom of the regulated release to change direction
of the conduit. The conduit offset cannot be
used with pulley tees. All other changes in direc-
tion must be made by using Ansul approved pul-
ley elbows, Part No. 423254 or 415670. See
Figure 96.
FIGURE 96

Fusible Link Selection
When possible, temperature readings should be taken at each
detector location to determine correct fusible link temperature rat-
ing. Temperature can be recorded using either a maximum regis-
tering thermometer, Part No. 15240, temperature tape or any other
accurate thermometer.

MANUAL PULL STATION REQUIREMENTS
A remote manual pull station allows the R-102 system to be man-
ually operated at some point distant from the regulated release
assembly. The pull station should be installed at a maximum
height of 60 in. (152 cm) and located in the path of exit. The pull
station is the only source of manual actuation of the regulated
release assembly.
Two styles of remote pull stations are available: metal stamped
and plastic molded.
The total length of the cable used for each manual pull station
within a system must not exceed 150 ft. (46 m).
The maximum number of pulley elbows that may be used per sys-
tem is 20.
One pulley tee, Part No. 15342, is allowed per system
Exception: When using a pulley tee, Part No. 15342, in the pull
station line, the maximum length of wire rope to each pull station
must not exceed 125 ft. (38 m) and the maximum number of
elbows must not exceed 18.

MECHANICAL GAS VALVE REQUIREMENTS
An Ansul or Ansul approved mechanical gas shut-off valve system
can be attached to the R-102 system. The system works both
mechanically and pneumatically by use of an air cylinder located
inside the regulated release assembly. Upon actuation of the fire

All valves above are UL listed and approved. They may be mount-
ed in any position. Pipe threads are type NPT. Ambient operating
temperature range of all valves is 32 °F to 120 °F (0 C to 49 'C).
The valves are not weatherproof and must be located indoors in
areas approved by the "authority having jurisdiction."
ELECTRICAL GAS VALVE REQUIREMENTS
A UL Listed electrically -operated gas shut-off valve can be
attached to the R-102 system to provide an electrical means of
shutting off the gas line at a predetermined point. If an electric gas
shut-off valve is used in the system it must be attached with both
an electric (snap -action) switch and a manual reset relay. For
more information on the types of electric (snap -action) switches,
refer to the Electrical Switch, Field Installation section. The manu
al reset relay is reviewed in this section.
All electrical connections should be performed by a QUALIFIED
ELECTRICIAN and in accordance with authority having
jurisdiction.
The following is a brief explanation of how the R-102 system oper-
ates with an Electric Gas Shut-off Valve attached:
With the regulated release cocked in the ready condition, the nor-
mally closed contacts in the snap -action switch allow current to
flow to the manual reset relay. With the relay coil energized, nor-
mally open contacts in the reset relay close, allowing the solenoid
in the gas valve to be energized.
