R-102 Restaurant Fire Suppression Manual SECTION 1 -GENERAL INFORMATION UL EX3470 ULC EX3470 2014-SEP-01 REV. 11 PAGE 1-3 DEFINITION OF TERMS (Continued) Pulley Elbow:A device used to change the direction of the wire rope which runs between: the regulated release mechanism and the detectors, the regulated release mechanism and the mechanical gas valve, and/or the regulated release mechanism and the remote manual pull station. Pulley Tee: A device used to change the direction of two wire ropes which run from a regulated release or a regulated actu- ator to two remote manual pull stations, or from two regulated releases or regulated actuators to a single mechanical gas valve or from one regulated release or regulated actuator to two gas valves. Regulated Actuator Assembly: An assembly which contains the regulator,pneumatic actuator,agent tank, and expellant gas hose within a metal enclosure.This assembly is used to pressur- ize additional agent tanks in a multiple tank system. Regulated Release Mechanism: An enclosed device within the AUTOMAN regulated release assembly which releases the expellant gas, activates alarms, and/or shuts off other devices when signaled automatically by a detector or manually with a remote pull station. Regulator: A device used to regulate the pressure from the nitrogen cartridge into the agent tank(s) when the system is actuated. Remote Manual Pull Station:A device which provides manual actuation of the system from a remote location. P.Remote Mechanical Release: A device that provides actua- tion gas, activates alarms, and/or shuts off other devices when signaled automatically by a detector, or manually with a remote pull station. Salamander Broiler: A broiler very similar in design to the upright broiler. A salamander broiler is used for general broiling of meats and fish, toasting, and holding/warming foods. Most contain a removable grease drip tray. Series Detector:Any detector located in-line between the regu- lated release assembly and the terminal detector. Silicone Lubricant: A heat-resistant organic compound used to lubricate 0-rings,rubber and mechanical components. Supply Line: The agent distribution piping which extends from the agent tank outlet and serves as a manifold for the branch lines. Terminal Detector: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."There is only one terminal detector per detection system. Transition:An extension of the hood or canopy which allows for the smooth transmission of gases, air, and vapors between the hood opening and the base of the ventilation duct. Vent Plug: A device used to prevent pressure build-up within the agent tank or agent distribution lines due to temperature fluctuations.

Each design requires several factors: correct nozzle choice, correct nozzle height above hazard,correct nozzle location and correct aiming 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 maximum 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 exceeded, an additional nozzle(s)will be required. Refer to the multiple nozzle requirements. Example: A fryer with a dripboard. The inside of the frypot without the dripboard measures 78 in.in depth x 78 in. in length (457 mm x 457 mm) and the inside of the overall area includ- ing the dripboard measures 18 in. in depth x 24 in. in length (457 mm x 610 mm). From the Table 'Maximum Cooking Area Dimension - Single Nozzle Fryer Protection,'either the 3N or the 290 nozzle should be selected to protect the fryer, depend- ing on the maximum nozzle height above the fryer and the positioning requirements allowed.
