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 1
R -102 or PIRANHA Regulated Actuators. In systems utilizing a
101 remote release, any combination of the maximum number of I
regulated actuators can be used. (5 zo a„)

Example: Protection is required for a duct that has an "A" dimen-
sion of 8.0 in. (20 cm) wide and a "B" dimension of 55 in. (140 cm)
long.
Referring to the table in Figure 2, if the "A" dimension is 8.0 in. (20
cm), the "B" dimension must not exceed 58.5 in. (149 cm). In this
example, the "B" dimension is 55 in. (140 cm), therefore, this duct
can be protected with a three flow application.
Read over from the 8.0 in. (20 cm) line on the table to the 1100
Module column. At that point, the chart shows that the "B" module
length for the 1100 nozzle can be 22.0 in. (56 cm). Center the 1100
nozzle in that module. The 2W module can now be centered with-
. in the remaining module.

Appliance Protection
The following pages detail types of appliance protection. Each
design requires several factors: correct nozzle choice, correct noz-
zle height above hazard, correct nozzle location and correct aim-
ing point.
Fryer— Single Nozzle 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
internal depth (horizontal dimension from front to back)
and length of the frypot.
B. FRYERS WITH DRIPBOARDS
If the fryer includes any dripboard areas, measure both
the intemal depth (horizontal dimension from front to
back) and length of the frypot portion, and then measure
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 which nozzle is needed
to protect the fryer based on the maximum dimensions listed.
A. If 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 the
table, and the maximum overall dimensions in the second
column of the table to select the correct nozzle. None of
the maximum dimensions in either column may be
exceeded.
3. If either the maximum frypot or the overall sizes are exceed-
ed, an additional nozzles) will be required. Refer to the mul-
tiple nozzle requirements. -
Example: A fryer with a dripboard. The inside of the frypot without
the dripboard measures 18 in. in depth x 18 in. in length (46 cm x
46 cm) and the inside of the overall area including the dripboard
measures 18 in. in depth x 24 in. in length (46 cm x 61 cm). From
the Table Maximum Cooking Area Dimension — Single Nozzle
Fryer Protection,' either the 3N or the 290 nozzle should be select-
ed to protect the fryer, depending on the maximum nozzle height
above the fryer and the positioning requirements allowed. Refer to
appropriate Figures.

GENERAL BULLETIN NO. 4927
DATE: . February 18, 2005
TO: All Authorized R-102 Restaurant System Distnbutors and OEMs
FROM: Mark Neumann — Marketing Manager, Commercial Suppression
SUBJECT New Salamander Broiler Protection for R 102TM Restaurant Fire Suppression Systems
Salamander broilers are now standard appliances in most commercial restaurants. As such, we are
pleased to offer a convenient new protection design using the R -102 Restaurant Fire Suppression
System.
This new design is UL Listed under. UL EX 3470 and ULC CEx747 and will be added to the R -102
Design Manual (Part No. 418087) at next reprint.
Salamander Broiler Protection
The R -102 Restaurant Fire Suppression System uses one 1N Nozzle (Part No. 419335) for
salamander broiler protection. The nozzle tip is stamped with 1N indicating that this is a one -flow
nozzle.
One 1N nozzle will protect a maximum hazard area (internal broiler chamber) of 16 in. (41 cm) deep
x 29 in. (74 cm) wide.
The single 1N nozzle must be located directly in line with either vertical edge of the broiler opening,
6 in. (15 cm) to 12 in. (30 cm) in front of the broiler, and 0 in. to 12 in. (30 cm) above the top of the
broiler. The nozzle must be aimed at the center of the broiler opening. See Figure.

Previous Salamander Broiler protection using two 1/2N nozzles remains an approved method.
Salamander broilers are generally mounted above other types of appliances. See Installation manual
for detailed design information concerning these other appliances.
