Those who Install, operate, recharge, or maintain these fire sup-
pression systems shouid read this entire manual. Specific sec-
tions will be ot particular Interest depending upon one's
responsibiiities.. . ' '
Design, Installation, recharge, and maliitenance of the system
musi conform to the limitations detaHed In this manual and per-,
formed by an individual who attendee an -ANSUL training pro-
gram and became trained to instaH, recharge, design, and main-'
taln theANSUl system.
Fire suppression systems are mechanical devfces. They need
periodic care. Maintenance is a vital step In the performance of
your fire suppression system. As such It must be performed In
accordanCe with NFPA 96 (Standard for the Installation of
Equipment for the Removal of Smoke and GreasecLaden Vapors
from Commerciai' Cooking Equlpmant) and NFPA 17 A (Standard
on Wet Chemical Extinguishing Systems) by an authorized
ANSUL distributor. To provide maximum assurance that the fire
suppression system wlH operate affectivaly and safely, mainte-
nance must be conducted at stx-month intervals, or earlier if the
situation dictates. Twelve-year maintenance must include agent
tank hydrostatic testing.

DESIGN AND APPLICATION
The ANSUL R-102 Restaurant Fire Suppression System is
designed to provide fire protection lor restauraol cooking apple
aneas, hoods, and ducts. tt is a pre-engineered group of mechan.
ical and electrical componenlS tor instaJiation by an authorized
ANSUL distributor. The basic system consists of an ANSUL
AUTOMAN regulated release assembly which includes a regulat.
ed release mechanism and a liquid agent storage tank housed
within ,a single endosure. Nozzles, detectors, cartridges, liquid
agen~ fusible links, pulley tees, and puliey elbows are supplied in
separate packages in the quantities needed for each fire suppres.
sion system arrangement.
The system provides automatic actuation; or tt can be actuated
manually through a remote manual pull s'.allon. The system is also
capable of shutting down appliances at system actuation. For
appliance shutdown requirements, refer to the current version of
NFPA 17 A, "Standard For Wet Chemical Extinguishing Systems:
and NFPA 96, "Standard For Ventilation Control and Fire
Protection of Commercial Cooking Operations.D
Additional equipment includes: remote manual pull station,
. > mechanical' and electrical gas valves, and electrical switches tor
automatic equipment and gas line shut-off. Accessories can be
added, such as alarms, wenning lights, etc., to installations where
required. . .
The R-102 system suppresses fire by spraying the plenum area,
the fitters, oooldng surfaces, and the exhaust due! system with a
predetermined flow rate of ANSULEX Low pH Uquid Fire
Suppressant. When the liquid ageol is discharged onto a cooking
appliance fire, tt cools the grease surface, and reacts with the hot
grease (saponification) Ionming a layer of soap-like foam on the
surface of the fat. This layer acts as Insulation . between the hot
grease and the atmosphere, thus helping to prevent the escape of
combustible vapors.
Exhaust fans In the ventilating system should be left on. The forced
draft of these fans assists the mCMlment of the liquid agent
through the ventilating system, thus aiding In the fire suppression
process. These fans aiso provide a cooling effect in the plenum
and duct after the fire suppression system has been discharged.
The system is UL listed with or without fan operalion.
Make up or supply alr fans, integral to the exhaust hood(s) being
protected, shall be shut down upon system actuation.
Along with the fire suppression system, the t.ot~ sy~tem design
must include hand portabie fire extinguisher(s) located within the
cookinglrestaurant area that can be used to manually suppress a
fire that may be. burning in an unprotected area GJass K extin-
guisher(s) must be provided for hazards where there Is a potential
for fires involving combustible cooking media {vegetable or animal
oils and fats). Refer'to NFPA 10. 'Standard For POr".able Fire
Extinguisher," for additional information.
UL LISTING
Tne R-102 Restauraol Fire Suppression System has been' tested
and is listed by Underwriters Laboratories, Inc. as a pre-engi-
neered system. The' system is in compliance with - UL Test
Standard 300, These tests require extinguishment of frres which
are initiated In deep fat fryers, ranges, griddles, char-broilers,
woks, upright broilers, chain-broilers, fliters, plenum chambers,
hoods, and ducts ailer pre-loading each appliance with a pre-
scribed amount. of cooking grease. Each fire 15 allowed to progress
to maximum Intensity before the fire suppression system is
actuated.

SYSTEM DESIGN "
The ANSUL R-102 Restauran! Fire Suppression System may be
used on a number of different types of restaurant cooking appl~
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 responsibie for the
design of the R-1 02 system must be lrajned 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 releasel any combination of the maximum number of
regulated actuators can be used,
. Both systems must actUate simultaneousiY:-"
. Each system must be designed and installed per Its appropri-
ate manual.
. Adjacent' appliances requiring protection must be protected
with the same type of syslam, either R-102 or PIRANHA,
unless the center-to-oenter spacing between the edjacent
R-102 and PIRANHA nozzles Is no less than 36 In. (91.4 cm).-
. 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 protecllon is a correel
system design. This section Is dMded into ten sub-sections: Noz-
zle Placement Requirements. Tank Quantity Requirements, Actu-
ation and ExpeIlarrt Gas Une Requirements, Distribution Piping
Requirements, Detection System Requirements, Manual Pull Sta-
tion Requirements, Mechanical Gas Valve Requirements, Ele~
ow Gas Valve Requirements, Electrical sWitch Requirements, and
Pressure Switch Requirements. Eech of these sections must be
completed before attempting any Ins'.allation.' System design
sketches should be made of ali aspeels of design for reference
during instwlation.
.
NOZZLE PLACEMENT REQUIREMENTI;
This section gives guidelines tor nozzle 'type,. positioning, and

. When determining number 01 nozz\es requiredl it is sometimes
an advantage to check the chart using the shortest side as Side

comparison may reveal a need for a lesser quantity of. nozzles
one way versus the other way,
When working with Chart t, the quantity of nozzles determined
must be equaily dIVided within tlie duct area. '
When working wtth Chart 2, one haH of the quantity of nozzles
determined must be equaily positioned in the top half of the area
of tlie dud and the remaining half of the nozzles must be posi-
tioned in the botiom half of the duct area.
Example: The duct to be protected has a Side .'A" of 40 in.
. (101.6 em) and a Side "8" of 60 in. (152.4 em). Referring to the

design requires several factors: correct: nozzle choice, correct noz-
zle height above hazard, correct nozzle location and correct aim"
ing point.
Fryer - Single Nezzle Protection
1. Design requirements for fryers are broken down into two
types.
A FRYERS WITHOUT DRIPBOARDS
If the fryer does not include a dripboard, 'measure the
internai depth (horizontal dimensien lrom front to back)
and length of the frype\.
B. FRYERS WITH DRJPBOARDS
If the fryer includes any dripboard .areas, measure both,
the internal depth (herizo.ntal dimension lrom front to
back) and length of the frypot portion, and then' meesure
the internal depth and length of the overall hazard area
including any dripboard areas,
2. Using Table, "Maximum Cooking Area Dimension - Single
Nozzle Fryer Protection; determine wihich nozzle is needed
to protect the fryer based on the maximum dimensions listed,
A. ff the fryer does not include a dripboard, use the maxi-
mum dimensions listed in the first column of the table to
select the correct nozzle.
B. If the fryer includes any dripboard areas, use both the '
maximum frypot dimensions in the first "column of lhe
table, and the maximum overall dimensions in the second
column of the table to. select the correct nozzle. None of
the maximum dimensions in eTther colurrln may be'
exceeded.
3. ff either the maximum trypot or the overall sizes are exceed-
ed, an additional nozzle(s) will be required. Refer to. the mul-
tiple nozzle requirements.
Example: A fryer with a dripboard. The Inside of the trypot 'Withotit " '
the dripboard measures 18 in. in depth x 18 in. in length (46 em x

Fryer'- Multiple Nozzle Protection
Design Requirements:
Fryers exceeding the coverage of a single nozzle can be dMded
into modules. Each module must not exceed the maximum area
alh;med lor a single nozzle. However, when-utilizing multiple nozzle
protection. the longest side allowed for a fryer with dripboard can
be used, regardless of whether the fryer has a dripboard or not
,.. The ..maximum size fryer that can be modularized is 864 in,2
. (5574 cm2) or in terms of ft, 6 fi2 (0.6 m2).
1. Design requirements tor 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 fhe frypot Then, multiply the depth and length to
obtain the area of the frypot in square in~es.
B. FRYERS WITH DRIPBOARD(S)
It 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.
Detennlne the area of both the frypot and the area of the
overall vat by mu~lpiying corresponding depth and length
dimensions.
2. Divide the frypot or overall vat into modules, each of which can
be protected by a - single nozzler based on the maximum
dimension and area coverage of the nozzle as specified In
Table, "Maximum Cooking Area Dimension - Muttipie Nozzie
Protection.R
A If the module considered does not include any portion of
the dripboard, use only the maximum trypot area and max-
imum dimension listed in the first column of the table to
s~lec::t 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 posslbiiity of an additional nozzle. "='" '
Options For Modularizing Fryers
The following Figure 20 shows approved methods of dMding (mod-
ularizing) fryers so that each section can be properly protected.
EACH MODULAR Ml€A, INCLUDING DAIPBOAFlC,
MUST NOT EXCEED J,97 1N.2 {32D7 cm~

Example: A fryer with a drfpbaard. The inside ""t without the drf,r
board measures 18 in. in depth x 30 in. in length (48 em. x 76 em)
and the inside of the overall vat including the dripboard measures
24 in. in depth x 30 in. in length (61 em x 76 em). Because the fryer
is 30 in. (76 em) in length, ft exceeds the coverage of a singie
noiz:le.
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 em). From
the Table, -Maximum Cooking AfBa Dimension - Multiple Nozzle
Fryer Protection, D either the 3N or the 290 nozzle should be seled-
ed to protect each fryer module, depending on the maximum noz-
zle height above the fryer and the, posffioning requirements
allowed. Refer to appropriate Figures, 15 through 19.

Multiple Nozzle Fryer Protection - Tilt Skillet / Braising Pan-.
Protection for tilt skillets or braising pans is to be based upon the
coverage limitations provided tor deep fa! tryer protection. Refer to
Section IV, DESIGN, starting on Page 4-10, lor maximum fryer
nozzle coverages and maximum tryer nozzle height limitations.
. Although the maximum 6 ft2 (0.6 m2) total surface cooking area
requirement applies to fryer protection, it does not apply to lih skii-
lets or braising pans.
Each tilt skilletlbraising pan protecied module must not exceed the
fryer Iim~ations for "MAXIMUM SIZE MODULE OVE~ WITH
DRIPSOAIRD" coverage per nozzle as described in Table on Page
4-11,
Tih skillets and braising pans generally utilize a hinged cover, Fryer
protection nozzles are to be placed toward the front of the appli-
ance to minimize the potential lor the tilt skillet or braising 'parr - -'-'-'-';

. Griddle Protection 1 N (1-Fiow) Nozzle - High.Proximity. -
Application .
The R.1 02 system uses four different nozzles for the protection of
griddles. One of the applicafions requires a 1-fiow nozzle and
three at the applications require a 2-flow nozzle.
High Proximity Application: 35 in. to 40 in. (89 to 102 ern) above
the cook'lng surface.
This high prOximity applicafion uses the 1 N nozzle, Part No..
419335.
The nozzle fip is stamped with 1 N indicating this is a one-flow noz-
zle and must be counted as one flow number.

Chain' Broi~er Protecfion ,. ".- .~-- .-' - '-
. The following listed proteclion guidelines can be applied to any
manufacturer's chain broilers, if the chain broiler meets the S!pecl-
tied parameters. Chain broilers utilizing cataiytic converters can
be protecteq tram overhead using model specific protection iden-
tified in the "Specific Application by Model" section in System
Design. Or, they can be protected with standard 1 N nozzle hori-
zontal chain broiler protection with the nozz}es positioned at either
end of the chain broiler openings. Refer to the Horizontal Chain
BroHer Protection section for specific design information.
Horizontal Chain Broiler Protection
The R.1 02 system can use twc 1 N Nozzles (Pari No. 419335) for
. horizontal 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 (tota of two flow numbers for each chain broiler
being protected). ------.
Two 1 N nozzles are aiways needed for chain broiler protection
when the hazard area to be protected does not meet the
"Overhead Broiler PratectionD requirements. The maximum interw
nal size of the broiler is 43 x 31 in. (109 em x 79 em). The nozzles
must be posfiioned at each end of the enclosed cooking chamber
1 to 3 in. (2.5 to 7.5 em) above thesurlace 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 comer as long as they are at
opposite ends of the chain broiier and positioned to discharge
. diagonally across the top of the chain. See Figures 53 and 54.

OVerhead Chain Broiler Protection

overhead chain broiler protection. The nozzl~ 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
internai broiler length and not less than 60% of the internal broiler
width, to a minimum size of 12 in. x 12 in. (30.5 x 30.5 'em). Internal
broiler size can not be larger than 32 in. x 34 in. (81 X 66 em).
When overhead protection is used, the nozzles must be centered
above the exhaust opening w~hin 4 to 8 in. (10 to 20 em) of each
other and they must be located 10 to 26 in. (25 to 88 em) above
: the top of the broiler ~rIace. See Figure 55..

To determine minimum opening size, multiply internal

Minimum allow!mle opening for overhead protection
would be 18 in.:x 14.4 in. (45.7 x 36.6 em).
&eause lhis brbiler 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 em) and therefore

SPECIFIC APPLICATION BY MODEL (Continued)
Nieco Broiler Model 940,962 or 960 With Catalytic Converter
Protection .
Note: Nieco broUers w~hout catalytic converters use stardard
chain broiler protection options.
Certain models of the Nieco broiler (Modeis 940, 962. and 960)
are equipped with a Catalytic converter to comply with new clean
air laws. Because of the converter, it is necessary to protect these
broilers in a special way. The guidelines for protecting these broil-
ers are ,as follows:
- The maximum internal brofiing area is 29 in. x 23.5 in. (74 em
x 60 em).
- An R--102 3-gailon system wiIl1 e maximum of 6 fiow numbers,
'. _...:'~ must be used for protec:tian of..eacl:t broiler, including -plenum,.
and duct
- Each Individual broiler must be protected w~ a minimum of (2)
. two, 1 N nozzles, Part No. 419335. The nozzies must be iocat~
~ ed as shown in Figure 80. .
- The brolier must be fitted with two 1 in. (2.5 em) high .gent bar-
riers on the angled suriace of the brol~er. If these have not been
completed by the equipment supplier, they must be .added in
the field.

OVERLAPPING NOZZLE COVERAGE
. Overlapping Coverage - Option 1
For each group 01 protected appliances under a common hood(s),
the overiapping nozzles must be located from right to left so that
each end nozzle is located a maximum of 6 In, (15,2 em) inside the
outside edge of the cooking hazard of each end appliance", and the
inside overlapping nozzies must be located between the two end
nozzles at a maximum spacing of 12 in, (30.5 em).
Hazard Zone
The hazard zone is defined as a theoretical, flat and level, rectan-
gular surtace, that includes all of the cooking hazards of the prer
tected appliances under a cammon hood(s),The purpose of the
hazard zone is to provide a means of locating the appliances and
the overlapping nozzles, as well as air:ning the overlapping noz-
zles. The hazard zone measures 2B in. (71,1 em) deep by the
length of the cooking hazan:J{s). The centerline of the hazard zone
must bisect the 2B In. (71,1 em) depth (from front to back) and run
from right-to-Ieft for the full width at the hazard zone.
Overlapping Nozzle Appliance Protection
Overlapping Nozzle Appliance Proteoffon is defined as protection
of cooking appliances by nozzles spaced uniformly at uniform ele-
vations under a common hOod(s), Overiapping proteoffon of appli-
anoes is continuous for the full length of the hood or divided when
group(s) of protected applianoes are separated by oounters or
appliances not requiring proteoffon,
Full hood continuous protection is defined as overlapping noz-
zie appliance protection' that .covers the appliance line-up located
under the tata hood length. All appliances requiring protection are
the appliances under the hood that can be an ignition source of
grease in the hood, grease removal device or the duct..
Group proteotion is defined as overlapping nozzle applianCe prer
tection that protects individual hazard zones located under a com-
mon hood. These "groups" of appliances may be separated by
appliances not requiring pratectlon1 such as steam equipment or
work tablesl or by dedicated appliance protection, such as saJa.

. Overlapping Coverage - Option 2
For each group of protacted appliances under a common hood(s),
the overlapping nozzles must be located from right to left so that
each end nozzle is located a maximum of 11.5 in. (29.2 em) inside
the outside edge of the cooking hazard of each end. appliance, and
the inside overlapping nozzles must be iocated betWeen the two
. end nozzles at a maximum spacing of 25.5 in. (64.6 em).
Hazard Zone
The hazard lone is defined as a theoretical, fiat and level, rectan-
gular surface, thai includes all of the cooking hazards of the pro-
tected appliances under a common hood(s). The purpose of the
hazard zone is to provide a means of locating the appliances and
the overlapping nozzles, as well as aiming the overlapping noz-
zles. The hazard zone measures 28 In. (711 mm) deep by the
length of the cooking hazard(s). The centerline of the hazard zone
must bisect the 26 in. (711 mm) depth (from front to back) and run
from rlght-to-Ieft for the fuil width of the hazard zone.. .
Overlapping Nozzle Appliance Proteellon
Overiapping Nozzle Appliance Protection is defmed as protection
of cooking appliances by nozzles spaced un~ormly at uniform ele-
vations under a common hood(s). Overlapping protection of appli-
ances is continuous for the fuil iength of the hood or divided when
group(s) of pnoIected appliances are separated by counters or
appliances not requiring protection. .
Full hood continuous proteellon Is detined as overlapping noz-
zle appliance protection that covers the appliance line-up located
under the total hood length. All appliances reqUiring protection are
the appliances under the hood that can be an ignition source of
grease in the hood, grease removal device or the duct,
Group protection is defined as overlapping nozzle appliance pro-
tection that protects individual hazard zones located under a com-
. man hood. These "groups' of appliances may be separated by
appliances not requiring protection, such as steam equipment or
work tables, or by dedicated appliance proteclion, such as sala-
mander broilers.
. See Figure 95 (full hood continuous protection) and Figure 96
(muttiple group protection).
Dedrcated Nozzj~ Appliance Protection
Appliance protection using dedicated nozzle coverage is defined
as protection of cooking appliances with enclosed cooking haz.
ards, such as upright broilers. which cannot be protected with
overlapping nozzles and therefore must be protected with nozzles
dedicated to the appliance.

General Design Limitations
. If overiapping appliance protection is mixed with dedicated appl~
ance protection on the same pipe system, THE OVERLAPPING
APPliANCE PROTECTION PIPING REQUIREMENTS MUST
BE FOLLOWED.
.. Overlapping protection requires the use of 3.0 gal (11.4 L)
tank(s) and a maximum of six (6) flows per tank
In installalions using tanks only intended tor overlapping protec-
lion, a single Double Tank nitrogen expellant gas carlridge can
be ulillzed with up to three (3) 3.0 gal (11.4 L) tanks.
In installations using both overlapping protection and conver).
tionai non-overlapping protection (ex. hood/duct or dedicated
appliance protection), a single Double Tank nitrogen expellant
gas cartridge can be utilized wfth up to three (3) 3.0 gal (11.4 L)
tanks, as long as none of the 3_0 gal (11.4 L) tanks exceed a
total fiow output of more than six (6) flows. .
If more than six (6) flows will be used in a conventional non-
overtapping tank, tt cannot share the same cartridge as tanks
intended for overlapping protection. In this case, an additional
Regulirted Actuator Assembly with another expellant gas car-
. tridge will be required.
. The 245 nozzie, Part No. 419340, must be used for "end of zone"
protection.
. The 260 nozzle, Part No. 419341, must be used for zone pro-
tection.
. . Maximum depth of zone is 26 In. (71.1 'cm).
. Refer to overlapping system piping requirements listed in Table 2.
. . Nozzle must be iocated 0 in. to 12 in. (0 cm to 30.5 em) forward
of zone centerline, aimed back at the zone centerline.
. . Nozzles must be speced e maximum of 11.5 in. (29.2 cm) from
. each end of hazard and then a maxjmum of 25.5 in. (64.8 em)
on center for the remaining' overtapping nozzles until the com-
plete hazard is covered.
. For appliance hazard surtaces with listed protection exceed-
ing the standard hazard zone of 26 in. (71 cm) in depth, the haz-
ard surface(s) must be aligned wfth the back edge of the hazard
zone, with the Iront edge overhanging the front edge of the zone.
See Appliance Chart, Table 1. .
. For appliance hazard surfaces that exceed the listed protec-
tion sizes, multiple zones must be. utiHzed. Align entire hazard
surface area within the multiple zones.
. AI! hood, duct, and individual appliance protection are as speci-
fied in the' R-1 02 Design, Installation, Recharge and Malnterr-
ance Manual, Part No. 418087.
. . All appliance protection currently listed in the R-1 02 Design
Manual, Part No. 416067, is also approved protection. Zone pro-

Detection Requirements For Overlapping Appliance
Protection
When utllizin9 overlapping appliance piotection, fusible link detec-
tors must be instalied on a maximum of 2 ft (0.61 m) cenillrs,
starting with detectors located in (under) the, duct opening(s).
Starting from the det.ctor under the duct opening, add detectors
on 2 ft (0,01 m) maximum spacing until the complete length of the
plenum area is covered, from one end to the other. The location ot
the last detector on each end of the plenum must not exceed
2 ft (0.01 m) from end of pienum.
Note: Standard defector piacement can also be utilized wilen
using overlapping protection. However, the overlapping detector
option cannot be used when utilizing standard R-102 protection,
. Refer to Pages 4-57 and 4-58 for detector placement.
TANK AND CARTRIDGE REQUIREMENTS----
Once the hazard analysis is compieted and the total nozzle flow
numbers are established, the quantity and size of agent tanks and.
cartridges needed to supply the nozzles with the proper volumes
of agent at the proper flaw rates can be determined. For cartridges
used "in the regulated release mechanism, flow capaclties, tank
quantities and stzes, and regulated release cartridge options are
given In the tabie below.

ACTUATION AND EXPELLA.NT GAS LINE REQUIREMENTS
This section contains the guidelines for installing the actuation and
expellant gas lines between the regulated release mechanism reg-
ulator, each reguiated actuator regulator, and each agent tank.
These limitations should be considered when selecting the com-
ponent mounting locations.
The actuation gas line is the length of pipe and/or hose that is run
from e~her the AUTDMAN Regulated Reiease Assembly or the
. Remote Release Assembly that directs high pressure from the
cartridge in the release to actuate one or more additional
Regulated Actuator Assemblies. The actuation gas line can consist
01114 In. Schedule 40 black iron, chrome-plated, stainless steel, or
gaJivanized steel pipe and fittings, andlor factory supplied stainless
steel braided actuation hose.
The expellant gas tine is the length of pipe that is run from the
regulator in e~her the AUTDMAN Regulated Release Assembly or
a Regulated Actuator Assembly that directs reguiated pressure to
the agent storage tanks to pressurize the tank and discharge the
agent The e><pellant gas line shall consist of 1/4 In. Schedule 40
black Iran, chrome-plated, stainless steel, or gaivanlzed steel pipe
and fittings. -

7. All threaded connections located in and abOve the protected
area must be seaied with pipe tape. Tape shouid be appiled to
male threads only. Make certain tape does not extend over the
end of the thread, as this could cause possible blockage of the
agent dlStribufion.
8. Belona installing blow-off caps on nozzles, apply a smail
amount of Dow Coming No. 111 silicone grease across the
opening in the nozzle tip and also B small amount coating the
exterior of the blow-oft cap. This will help keep cooking grease
from buildIng up on the cap.

DETECTION SYSTEM REaUIREMENTS
Once the fire suppression system design has been determined, a
detection system design must be completed. Thi!3 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.
. i. The Tenminal Detector (Part No. 417368) is the last ina senes
of detectorsl or the ant)' detector used in a single-detector sys-
tem. 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.4 i 7369) is any detector iocated in-
line between the regulated release mechanism and the termi-
nal detector. - -- ... '-. -. "
. Detector~ulley ElbowlConduft Off-Set Design Umitations
. i. Conduit nuns, pulley elbows, and number of detectOrs per sys-
tem must be within the approved system guidelines. The f0l-

. Remote Releases (Part No. 433485) can be used lor system
actuation. Each "/01 remote release allows the use of a mfOO-
mum of 15 'scissor" style detectors (14 series and 1 tenminal)
for a total of 75 detectors ~ needed.

NOTICE
When gas" appliances are used and the flue
gases from the burner are exhausted into the
due, 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 additionat detectors. ..
ELECTROSTATIC PRECiPITATOR
If an electrostatic precipitator "is located ai or near the base of the.
exhaust duct, it is necessary to locate a detector beiow the pre-
cip~ator, at the bese of the duct, and also locate one In the duct,
... just above the precipitator. See Figure 119.
When installing. the detector bracket and system conduit, make
certain they do not interiere with the operation 'of the precipltat?!'.
Note: On secondary filtration units utmzing multiple filter

COOKING APPUANCES
\j the cooI<ing appliance is located under an exhaust duct where a
detector has been mounted, it is normally not necessary to utilize
another detector tor that cooking appliance, provided the detector
. is not more than 12 in. (30 em) Into the'duct and the appliance has
no larger cooking surface than 48 in. x 48 in. (121.9 cm x 129.1 .

Note:. If two (2) appliances are iocated under a duct opening
where a detector has been mounted and both appliances togeth-
er do not exceed a cooking surface of 48 in. x 48 in. (121.9 em x
121.9 em) and the detector is iocated above both the protected
appliances, It is not necessary to utilize an additional detector pro-

imum of one detector. Cooking appliances with a continuous cook-
ing surface exceeding 48 in. x 48 in. must be protected by at least
one detector per 48 in. x 48 in. cooking area. Detectors used for
cooI<ing appliances must be located above the protected appli-
ance toward the exhaust duct side of the appliance. The detector
should be located in the air stream of the appliance to enhance
system response time.
.. Note: For overlapping detector coverage, see Page 445 for
design requirements.
Detection Line Requirements
CONDUIT
Rigid conduit ar 1/2 inch EMT thin-wall condult'"may be used.
Standard steel conduit fittings (compression type are recommend-
ed) 'must be employed to praperly install the detection system. All
conduit or pipe must be firmly supported. When using pipe, make
certain that all ends are caretully reamed, deburred 'and blown
clear of chips and scale before assembly.
.
NOTICE
The conduit offset can be used at the tap or bot-
tom of the regulated release to. change direction
of the conduit The canduit offset cannot be.

MANUAL PULL STATION REQUIREMENTS
A remote manual pull station allows the R-1 02 system to be man-
ually operated at some point distant from the regulated release
assembly. The pull station should be installed at a height of 42-48
In. (107-122 cm), in accordance wrth the requirements of the
American Dlsalbiirties Act (ADA) and the Authority having Jurisdic-
tion. and iocated in the path of egress. The pull station is the only
source of manllal actuation of the regulated release assembly.
The !etallength of the cable used tor each manual pull station wrth-
in a system must not exceed 150 it (46 m).
The maximum number of pulley elbows that may be used per pull
station is 20.
. One pulley tee, Part No. 427929, is allowed per oaIble system.
The maximum length ot cable from the AUTOMAN to a pull station
is 150 ft (45.7 m) with a maximum of 20 pulley elbows used per
side of the tee. As the tee is located farther from the AUTOMAN,
the 150 ft (45.7 m) maximum must be observed but as pulley
elbows are placed between the AUTOMAN and the tee, they must
be deducted from the available pulley elbows (20) allowed on each
side.
Example: If 10 pulley elbows are placed between the AUTOMAN
and the pulley tee, the maximum available pulley elbows left for
. use on each side 01 the tee is 1 0 per side. See Figure 123 for three
different examples. (Nole: Both must be gas valves or both must
be pull stations. Mixing Is not allowed.)

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
bath mechanically and pneumatically by use of an air cylinder
located inside the regulated release assembly. Upon actuation of
the fire suppression system, a pneumatically-operated air cylinder
assembly will mechanically close the gas shut-off valve.
The total length of the oaIble for each mechanical gas valve must
not exceed 150 ft (46 m). The maximum number of pulley elbows
that may be used is 20 for each valve. .
. One pulley tee (Par! No. 427929) is allowed per cable system.
The maximum length of cable from .the AUlDMAN to a gas valve is
150 ft (45.7 m) with a maximum of 20 pulley elbows used per side
01 the tee. As the tee is located. farther from the AUTOMAN, the
150 ft (45.7 m) maximum must be observed but as pulley elbows are
placed between the AUTOMAN and the tee, they must be deducted .
from the available pulley elbows (20) allowed on each side.
Example: H 10 pulley elbows are placed between lhe AUlDMAN' .
and lhe pulley tee, the maximum available pulley elbows left for
~ Use on each side of the tee is 1 0 per side. See Figure 123 for three
different examples. ._'.

MECHANICAL GAS VALVE REQUIREMENTS (Continued) .. -- .
All valves above are UL listed and approved. They may be mount-
ed in ary position. Pipe threads are type NPT. Ambient operating
temperature range of all valves is 32 OF to 120 OF (0 OC to 49 oc).
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-1 02 system to provide an electrical means of
shutting off the gas line at a predelenmined point If an electric gas
shut-off valve is used in the system ~ must be attached with both
an electric (snap-action) SlNitch and a manual reset relay. For more
Infonmatton on the types of electric (snap-action) switches, refer to
the Electrical Switch, Field Installatton section. The menuel reset
relay is reviewed in this section.
All electrical connections should be perfonmed by a QUALIAED
ELECTRICIAN ard in accordanoe with authority having
jurisdiction. .
The following is a brief explaraiion of how the R-1 02 system oper-
ates with ar Electrio 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 curr"erit to'
flow to the manual reset relay. Wrfh the relay coil energized, nor-
mally open contacts in the reset relay close, allowing the solenoid
in the gas valve to be energized. . .
Once the R-102 system is actllvated, the normallY closed contacts
In the snap-action sW~ch will open, de-energizing the reset relay.
This will, in turn, Dpen the contacts in the relay which will cause the
gas valve to become de-energized and dose.
The system must be re-anmed and the 'push to reset' button on
the reset relay must be operated to reopen the gas valve.
tt is important to note that a power tailure or an electrical power
interruption will cause the gas valve to close even though the sys-
tem was not fired. .
In either case, whether in a fired condition or when a power failure
has occurred, the manual reset relay and electric gas shut-off
valve must be reset to resume a normal operating condition, For
resetting, refer to the "Recharge and Resetting Procedures"
section in this manual.
Approvals
ANSUL gas valves listed in this sectton are UL listed and approved
for 110 VAG. If more information is required, refer to the Gas and
Oil Equipment List of Underwriters Laboratories, inc. under
"Electrically Operated Valves Guide No. 440 AS' or consu~ Ansul
Incorporated, Marinette, Wisconsin 54143~2542.
If other gas valves are used, thay shall be "UL listed electrically-
operated safety vaIIves for natural or LP gas as required, of appro-
priate pressure and temperature rating, 110 VAC/SO Hz."The infor-
metion on temperature ard type of gas that the valves are suitable
for may be found in the Gas and 011 Equipment List of
Underwriters Laboratories, Inc. under "Electrically Operated
