2 Graph 1 Pressure Limiting Driver PLDTM Summary for Discharge Pressure Control The Clarke PLD for Discharge Pressure Limiting Control is a UL/FM certified diesel engine fire pump driver which reduces pump speed to limit the maximum pump discharge pressure to prevent over-pressurization of the sprinkler system. See Graph 1 Certain Clarke PLD equipped engines (-P1 Models) are available with one of three different factory settings: 100 psi (maximum pressure held between psi), 170 psi (maximum pressure held between psi) and 240 psi (maximum pressure held between psi). Refer to Table 1 for Discharge Pressure Limiting Control values. Certain Clarke PLD equipped engines (-D and DS Models) can be Factory Set at any specific pressure between 100 PSI and 350 psi. The value must be factory set and is not field adjustable, refer to Table 1. The Clarke PLD senses sprinkler system water pressure via a sensing line connected to the pump discharge pipe (between the pump flange and the discharge check valve), and adjusts engine speed to manage discharge pressure, see Graph 1. NOTE: -P1 models require a drainline, -D and DS models do not. A Clarke PLD requires a controller equipped with visible and audible alarms to comply with NFPA 20 Per (8). When using a Clarke PLD for Discharge Pressure Liming Control, NFPA 20 requires the installation of a pressure relief valve. During commissioning, the PLD device is turned off in order to verify the performance of the pump to the factory test curve. Therefore fittings and pipe with the appropriate higher pressure rating need to be used from the pump discharge flange to and including the gate or butterfly discharge isolating valve. Page 2 of 20

A speed control -D Models: 100/350 psi Factory Set Point (not field system used to limit the total discharge pressure by reducing adjustable) the pump driver speed from rated speed Variable speed pressure limiting control drivers, as defined in this standard, shall be acceptable to limit system pressure. Features The set pressure plus maximum pressure variance of the Controls System Over-Pressure while meeting NFPA 20. Controls System Over-Pressure without any device in the main supply line, where a failure condition of a device in the main supply line could interrupt the water supply. Saves design time by eliminating multiple engine/pump combinations as previously necessary. A simple calculation using the Clarke online PLD-D calculator verifies the Clarke PLD equipped engine will keep the sprinkler grid from exceeding the system pressure limit. it Reduces the quantity of the pressure control valves on high rise applications by limiting the maximum pressure applied to the sprinkler system. Enables the use of pumps with steeper rise to shut off pressure curves. Steeper pump curves typically require less horsepower which can reduce the total cost of fire protection. Eliminates the discharge of water from the pressure relief valve during the weekly pump test. No valve in-line with discharge. Allows smaller pipe diameter. Eliminates pressure reducing valves in ESFR systems. variable speed pressure limiting controlled systems during variable speed operation and adjusted for elevation shall not exceed the pressure rating of any system component Pressure relief valves and pressure regulating devices in the fire pump installation shall not be used as a means to meet the requirements of Where a diesel engine fire pump is installed and where a total of 121 percent of the net rated shutoff (churn) pressure plus the maximum static suction pressure, adjusted for elevation, exceeds the pressure for which the system components are rated, a pressure relief valve shall be installed. Each engine has a minimum RPM it can operate down to. In order to determine if the Clarke PLD engine can reduce enough pressure for an installation, each job will need to be reviewed either using the PLD-D Calculator, found on our website, or by filling out the PLD-D application Form and faxing to Donna Penter at or by ing dpenter@clarkefire.com for review. Clarke must receive a copy of the completed PLD-D Application Form or a copy of the PLD-D Calculator or the PLD-D Log Number form with the order. Page 3 of 20

4 Graph 1 Pressure Limiting Driver PLDTM Summary for Suction Pressure Control The Clarke PLD engine for Suction Pressure Limiting Control is a UL/FM certified diesel engine fire pump driver which reduces engine speed to maintain a minimum suction pressure value to prevent under-pressurization of the sprinkler water supply, see Graph 1. The Clarke PLD can be factory set at any specific minimum suction pressure between 5 psi and 30 psi. Note this set point is not field adjustable. The Clarke PLD senses the fire pump suction pressure via a sensing line connected to the pump supply pipe (between the pump flange and the suction isolating valve), and reduces engine speed to manage suction pressure, see Graph 2. Page 4 of 20

5 Suction Pressure Control 5-30 psi Factory Set Point (not field adjustable) Features Controls minimum suction pressure while meeting NFPA 20 Reduces water flow to maintain minimum suction pressure by reducing engine speed. Typically will not shut off pump during operation. No valve in-line with supply water. Substitutes for break tank. If minimum suction pressure cannot be maintained, engine will signal controller. Designed to protect water supply when number of open sprinkler heads exceeds design criteria. NFPA 20 (2010) Language for Use and Acceptability of Variable Speed Suction Limiting Control Variable Speed Suction Limiting Control. A speed control system used to maintain a minimum positive suction pressure at the pump inlet by reducing the pump driver speed while monitoring pressure in the suction piping through a sensing line Low Suction Pressure Controls Low suction throttling valves or variable speed suction limiting controls for pump driver that are listed for fire pump service and that are suction pressure sensitive shall be permitted where the authority having jurisdiction requires positive pressure to be maintained on the suction piping Where the authority having jurisdiction requires positive pressure to be maintained on the suction piping, a pressure-sensing line for a low suction pressure control, specifically listed for fire pump service, shall be permitted to be connected to the suction piping. Each engine has a minimum RPM it can operate down to. In order to graphically see how a Clarke PLD engine will perform for a specific application, each job will need to be reviewed either using the PLD-S Calculator, found on our website, or by filling out the PLD-S Application Form and faxing to Donna Penter at ; or by ing dpenter@clarkefire.com for review. Clarke must receive a copy of the completed PLD-S Application Form or a copy of the PLD-S Calculator l Form or the PLD-S log number with the order. Page 5 of 20

16 Graph 1 Pressure Limiting Driver PLDTM Summary for Discharge Pressure Control The Clarke PLD for Discharge Pressure Limiting Control is a UL/FM certified diesel engine fire pump driver which reduces pump speed to limit the maximum pump discharge pressure to prevent over-pressurization of the sprinkler system. See Graph 1 Certain Clarke PLD equipped engines (-P1 Models) are available with one of three different factory settings: 100 psi (maximum pressure held between psi), 170 psi (maximum pressure held between psi) and 240 psi (maximum pressure held between psi). Refer to Table 1 for Discharge Pressure Limiting Control values. Certain Clarke PLD equipped engines (-D and DS Models) can be Factory Set at any specific pressure between 100 PSI and 350 psi. The value must be factory set and is not field adjustable, refer to Table 1. The Clarke PLD senses sprinkler system water pressure via a sensing line connected to the pump discharge pipe (between the pump flange and the discharge check valve), and adjusts engine speed to manage discharge pressure, see Graph 1. NOTE: -P1 models require a drainline, -D and DS models do not. A Clarke PLD requires a controller equipped with visible and audible alarms to comply with NFPA 20 Per (8). When using a Clarke PLD for Discharge Pressure Liming Control, NFPA 20 requires the installation of a pressure relief valve. During commissioning, the PLD device is turned off in order to verify the performance of the pump to the factory test curve. Therefore fittings and pipe with the appropriate higher pressure rating need to be used from the pump discharge flange to and including the gate or butterfly discharge isolating valve. Page 16 of 20

Features The set pressure plus maximum pressure variance of the Controls System Over-Pressure while meeting NFPA 20. Controls System Over-Pressure without any device in the main supply line, where a failure condition of a device in the main supply line could interrupt the water supply. Saves design time by eliminating multiple engine/pump combinations as previously necessary. A simple calculation using the Clarke online PLD-D calculator verifies the Clarke PLD equipped engine will keep the sprinkler grid from exceeding the system pressure limit. it Reduces the quantity of the pressure control valves on high rise applications by limiting the maximum pressure applied to the sprinkler system. Enables the use of pumps with steeper rise to shut off pressure curves. Steeper pump curves typically require less horsepower which can reduce the total cost of fire protection. Eliminates the discharge of water from the pressure relief valve during the weekly pump test. No valve in-line with discharge. Allows smaller pipe diameter. Eliminates pressure reducing valves in ESFR systems. variable speed pressure limiting controlled systems during variable speed operation and adjusted for elevation shall not exceed the pressure rating of any system component Pressure relief valves and pressure regulating devices in the fire pump installation shall not be used as a means to meet the requirements of Where a diesel engine fire pump is installed and where a total of 121 percent of the net rated shutoff (churn) pressure plus the maximum static suction pressure, adjusted for elevation, exceeds the pressure for which the system components are rated, a pressure relief valve shall be installed. Each engine has a minimum RPM it can operate down to. In order to determine if the Clarke PLD engine can reduce enough pressure for an installation, each job will need to be reviewed either using the PLD-D Calculator, found on our website, or by filling out the PLD-D application Form and faxing to Donna Penter at or by ing dpenter@clarkefire.com for review.

18 Graph 1 Pressure Limiting Driver PLDTM Summary for Suction Pressure Control The Clarke PLD engine for Suction Pressure Limiting Control is a UL/FM certified diesel engine fire pump driver which reduces engine speed to maintain a minimum suction pressure value to prevent under-pressurization of the sprinkler water supply, see Graph 1. The Clarke PLD can be factory set at any specific minimum suction pressure between 5 psi and 30 psi. Note this set point is not field adjustable. The Clarke PLD senses the fire pump suction pressure via a sensing line connected to the pump supply pipe (between the pump flange and the suction isolating valve), and reduces engine speed to manage suction pressure, see Graph 2. Page 18 of 20

19 Suction Pressure Control 5-30 psi Factory Set Point (not field adjustable) Features Controls minimum suction pressure while meeting NFPA 20 Reduces water flow to maintain minimum suction pressure by reducing engine speed. Typically will not shut off pump during operation. No valve in-line with supply water. Substitutes for break tank. If minimum suction pressure cannot be maintained, engine will signal controller. Designed to protect water supply when number of open sprinkler heads exceeds design criteria. NFPA 20 (2010) Language for Use and Acceptability of Variable Speed Suction Limiting Control Variable Speed Suction Limiting Control.
