SECTION IV - SYSTEM DESIGN UL EX. 3470 ULC CEx747 Page 4-40 REV. 2 10-1-02 TANK AND CARTRIDGE REQUIREMENTS Once the hazard analysis is eompleted 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 flow rates can be determined. For cartridges used in the regulated release mechanism, flow capacities, tank quantities and sizes, and regulated release cartridge options are given in the table below. Total Quantity and Flow Size of Numbers* Thnk(s} .. 1 - 5 (1) 1.5 Gallon 6 -11 (1) 3.0 Gallon 11 -16 (1) 1.5 Gallon (1) 3.0 Gallon .. 16 - 22 (2) 3.0 Gallon Double 101-30** When one or more regulated actuators are used, the following tank and cartridge combinations apply for each regulated actuator: Regulated Actuator Regulated Actuator Tank(s) Cartridge (1) 1.5 Gallon LT-20-R or 101-10 (1) 3.0 Gallon LT-3O-R or 101.20 (1) 1.5 Gallon and LT-A-101-3O or 101-30** or .. (1) 3.0 Gallon double tank (2) 3.0 Gallon LT-A-101-3O or 101-30** or .. double tank Regulated Release Cartridge Options Nitrooen Carbon Dioxide LT-20-R 101-10 LT-3O-R 101-20 Double 101-30 . For exceptions to maxItrom flow numbers, see Distribution Piping Requirements for 1.5 gal- lon and 3.0 gallon systems in this Section. .. .. The 101-30 cartridge can not be used when (2) two 3.0 gallOn tanks are manifolded together.) For higher total flow numbers (23 to 110), multiple cartridges and regulated actuators are required as shown in the System Selection Guide in Section IX - Appendix. .. .. ACTUATION AND EXPELLANT GAS LINE REQUIREMENTS This section contains the guidelines for installing the actuation and expellant gas lines between the regulated release mechanism reg- ulator, each regulated actuator regulator, and each agent tank. These limitations should be considered when selecting the com- ponent mounting locations. Aetuatlon Gas Line - 6 to 8* Tanks Maximum . 8 Tank maximum reflects the utilization of 3 tank regulated actuators. 1. Use only 1/4 in. Schedule 40 black iron, hot-dipped galva- nized, chrome-plated, or stainless steel pipe and fittings. 2. The actuation gas line piping is installed from the regulated release mechanism to each regulated actuator connected within the system. The total leng1h of the actuation gas line from the regulated release assembly to the regulated actuator assembly(ies) must not exceed 20 ft. (6 m) when using an L T-2Q-R, an LT-3Q-R nitrogen cartridge, or a 101-10 or a 101- 20 carbon dioxide cartridge. See Figure 71. ..
