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 1111 R -102 or PIRANHA Regulated Actuators.

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.

Normally electrostatic precipitators do not require protection but FIGURE 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.

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 internal 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 nozzle(s) will be required. Refer to the mul- tiple nozzle requirements. Example: A flyer 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.

SECTION IV — SYSTEM DESIGN UL EX. 3470 ULC CEx747 Page 4 -54 REV.2 3 -1-04 DETECTION SYSTEM REQUIREMENTS Once the fire suppression system design has been determined, a Detector Placement Requirements detection system design must be completed. This section contains EXHAUST DUCTS guidelines and limitations for detection system installation. Each exhaust duct must have at least one detector installed in the Detector Identification duct entrance, located in the airstream of the cooking vapors, or at The two types of detectors are distinguished from each other by a maximum of 20 fL (6.1 m) into the duct opening. See Figure 99. 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 _ '' `Fi` 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 I detector located in -line between the regulated release mech- anism and the terminal detector. 20 FT.
