     BACKGROUND 
     1. Field of Invention 
     The present invention relates generally to fire control, and, more particularly, to systems and methods for residential fire sprinkler systems. 
     2. General Background 
     The National Fire Protection Association, Standard for the Installation of Sprinkler Systems in One- and Two-family Dwellings and Manufactured Homes (NFPA 13D) 2007 edition, establishes standards for fire sprinkler protection of residential dwellings, including water supply requirements. In some cases the existing water supply can provide a sufficient volume of water but not at a pressure necessary to meet the sprinkler demand required by NFPA 13D. In these cases the existing water supply for the residential fire sprinkler system can utilize pressure elevation through the use of a pump. In other cases, the existing water supply can be deficient in both the volume and pressure required by NFPA 13D. In these cases, the packaged residential fire sprinkler pump system can include the addition of a water storage tank.

     SUMMARY 
     Embodiments of the present invention relate to a packaged residential fire pump system designed to supplement or replace existing water supplies for fire sprinkler protection of one- and two-family dwellings. According to various embodiments, the system can contain all features required for an automatic operation after sprinkler activation, or during a system test. Prior systems have been designed and constructed in a manner that could easily be disabled, either deliberately or inadvertently. Such prior systems also lack other features such as operational supervision of critical mechanical and electrical functions, and are difficult to functionally test. Embodiments of the present invention overcome these deficiencies by eliminating water control valves, and integral motor thermal overload devices, and adding supervision of electrical controls, and providing a simple means for flow testing. In various embodiments, a pre-engineered system design can eliminate most calculations previously required to hydraulically design a residential sprinkler system including: Water supply, system elevation, meters, backflow devices, piping, and fitting friction loss calculations, and sprinkler operating pressure. In various embodiments, these calculations can be replaced with a scheduled piping layout using sixteen (16) foot fire sprinkler head spacing.

A pressure gauge  16  can be installed to monitor static and residual system pressures. A pressure switch  15  can be installed to initiate pump  11  operation upon a drop in system pressure, or opening of the system test valve  18 . A one-quarter inch circulation line  14  can provide for pump cooling when running in a no-flow condition. Circulation line  14  can also function to automatically prime the pump  11  during system start-up. Test Valve  18  can be a three-quarter inch gate valve designed to allow the simulation of single sprinkler head activation for test purposes. Test valve  18  can be designed to be slow opening/closing thereby eliminating water hammer during testing. 
       FIG. 4  is a partial left side view of the packaged residential fire pump system showing the alignment of drain and test assemblies, in accordance with various embodiments. As shown in  FIG. 4 , an electrically operated solenoid valve  12  can be provided as an automatic tank fill device. To avoid the passing of debris that could affect the operation of solenoid  12 , a strainer assembly  17  can be installed upstream of the solenoid  12 . The system test assembly discharge line  20  can be piped to the exterior at an elevation above the top of the tank  3 . This discharge line  20  can terminate at an open test sprinkler  21 . The open test sprinkler  21  can have an operating element retaining screw removed to assist in keeping the test water discharge away from the house. In various embodiments, the test sprinkler  21  can be threaded into a single outlet half-inch white rectangular cluster cover  22  to restrain the test sprinkler  21  from movement and provide a finished appearance. 
     The discharge pipe  20  can also function as a drain for system maintenance or repair. In various embodiments, control piping assembly  4  can be constructed of copper to reduce corrosion. A one inch pipe stub  19  can be designed for connection to the sprinkler system piping. A one-inch pipe stub  25  can be provided for connection to the domestic supply. A one and one-quarter inch pipe stub  6  can be provided for connection to the tank  3 . A tank drain valve  48  can be installed in the tank connection  6  to allow for draining the tank  3  for maintenance. The tank drain valve  48  can also include a hose bib to provide access to the tank water for sanitation use during a time of prolonged utility outages. 
     Packaged Residential Fire Pump System—Controller Assembly 
       FIG. 2  is a front view of the packaged residential fire pump system  100  showing electrical components of the controller assembly  2  in accordance with various embodiments. As shown in  FIG. 2 , the controller assembly  2  electrical control components can be mounted in a National Electrical Manufacturers Association (NEMA) minimum type two enclosure powder coated red texture finish. In  FIG. 2 , the support frame assembly, controller assembly door, and tank assembly have been removed for clarity. Controller assembly  2  components can be installed in the enclosure or other moisture resistant box, and control wiring to the pressure switch and the pump can be installed in moisture resistant conduit. Mounted in the controller assembly  2  is, in various embodiments, a three pole rotary disconnect switch  35  with a yellow/red handle  32 . Disconnect  35  can be configured to switch power for the motor, system controls, and the supervisory light circuit. Additional features mounted on the controller assembly enclosure  41  cover can include: A green Light Emitting Diode (LED) indicator  31  can be configured to illuminate only when the disconnect switch  35  is in the “on” position and powered in all phases with no system trouble, a momentarily closed motor stop switch  30 , and a red LED  33  configured to illuminate when system trouble exists. 
     Typically, system operation is initiated by a drop in water pressure caused by the fire sprinkler activation. This drop in pressure is sensed by the pressure switch  15 , closing the system supervision contactor  42  and motor contactor  43 , starting pump/motor assembly  1 . The system  100  can employ a minimum run timer  36  that assures upon activation, ten minutes of operation without interruption as required by NFPA  13 D. This timer can also be provided with a parallel circuit to assure system operation if the timer  36  fails or is removed. Power for the control circuit comes directly from the power distribution block  50 . The pump driver motor  10  and external equipment can be protected by circuit breakers  38  and  39 . The controller assembly  2  can be protected from voltage surges with an inline surge suppressor  24 . For safety the external control circuit, supplying the tank floats assembly  26  is reduced to 24VAC by transformer  40 . Relays  44  through  47  can provide supervision of system disconnects and other critical functions. Terminal blocks  34  can be provided to facilitate interface with external power and control circuits. An interface module  49  can be provided to allow an alarm interface with an existing smoke detection system. 
     The controller assembly  2  can be designed to start the pump/motor assembly  1  upon activation a single valve or the opening of the system test valve (for example, using a factory set pressure switch 5/70 psi). Pump  11  activation can utilize a NEMA rated magnetic contactor. To prevent the switch from remaining turned off, the disconnect switch can be configured to disable a kitchen lighting circuit anytime it is in the “off” position. A separate 15 amp breaker can be installed on the inside of the controller assembly  2  outer door to allow the kitchen lighting circuit to be disconnected if required for maintenance. According to various embodiments, a one minute minimum run timer can be activated anytime the pump  11  runs to avoid the potential short cycling that could occur with fluctuations in the supply or discharge pressures. This timer can allow the system to serve a function similar to a “jockey” or pressure maintenance pump in commercial sprinkler systems. After the initial one minute the controller can again check the pressure switch, and if the pressure is below seventy psi and over five psi the run timer can cycle for ten minutes and activate the system alarm. After the ten minute run, the controller can again check the system pressure, and if the pressure is below seventy psi or over five psi, the ten minute run timer again recycles. The low/high pressure shut down does not override the timers, ensuring that once the system is activated it will run for at least one minute. The system can contain a low/high pressure shutdown intended to protect the pump from burning up if the water supply is exhausted. This feature can also shut down the alarm circuit automatically. 
     The controller can be supplied with green/red LED pilot lamps. Other indicators can also be used. The green lamp can be lit anytime the system disconnect is in the closed position, powered, and the system is ready to activate. The red lamp can be lit, for example, when the control valve is closed or a low-pressure condition exists. A pump running alarm-closed contact can be installed in the controller to activate anytime the controller switches from the sixty second to ten minute timer. This contact can activate a smoke detector alarm circuit, for example. A red trouble light and audible signal similar to smoke detector low battery can be mounted on the controller assembly  2  and be activated anytime the system shut-off valve is in the closed position, the system discharge pressure is below five psi or below, or any other functions necessary for system operation. Activation of the trouble signal can cause the green light to turn off. 
     In various embodiments, the controller assembly  2  can comprise a processor such as, for example, a microprocessor, microcontroller, or microcomputer executing a sequence of programmed instructions. The instructions can be compiled from source code instructions provided in accordance with a high level programming language such as C++. The instructions can also comprise code and data objects provided in accordance with the Visual Basic™ language, for example. In alternative embodiments, the controller can comprise discrete electrical and/or electronic components, and may include an Application Specific Integrated Circuit (ASIC) including hard-wired circuitry designed to perform the mode control operations described herein. The controller can be coupled to subsystems using an interface for transferring digital information. The interface can comprise, for example, a parallel data/command bus, or may include one or more discrete inputs and outputs. Additional functions that can be controlled by a processor include: Alarm signaling, wiring supervision, electrical supply supervision, water supply supervision, tank high/low water level supervision, testing data storage, or integration with existing fire/smoke/carbon monoxide and security systems.  FIG. 3  is an electrical schematic diagram of operational logic of the packaged residential fire pump system  100  in accordance with various embodiments.

     The pump/motor assembly  1 , control piping assembly  4 , and controller assembly  2  can be attached to the support frame assembly  5  using corrosion resistant bolts and nylon lock-nuts.  FIGS. 5   a  through  5   c  are a front, left side, and detail views, respectively, of a support frame assembly, insulation package, and mounting assembly for the residential fire pump system in accordance with various embodiments. The frame  25  can be of welded construction with minimum fourteen gauge slotted angle stock two and one-half by one and one-half inch, primed and painted red to resist corrosion. The entire support frame assembly  5  can be designed to be attached to a wall using interlocking brackets constructed of thirteen-sixteenth inch fourteen gauge steel strut  23 . The entire frame assembly can be mounted a minimum of twelve inches above the floor making the electrical components less susceptible to water damage, and below the tank  3  maximum water level for the self priming function. The support frame assembly  5  can be designed to allow for the installation of an R-13 rigid insulation barrier  29  between the mounting surface, and the wetted components of the packaged residential fire sprinkler system to provide compliance with energy efficiency requirements, and preventing system damage due to freezing. The insulation barrier  29  can be provided with a thermal barrier  28  consisting of a one-quarter inch thermal barrier  28  to protect the rigid insulation  29  from fire. 
     Packaged Residential Fire Pump System—Water Storage Tank Assembly 
     As shown in  FIG. 1 , the system can be configured to use a storage tank  3  as a water supply (supply volume is typically designed to equal the sprinkler system demand×ten minutes). Tank  3  can be sized to fit through a standard thirty-six inch exterior residential door and constructed of translucent polyethylene or polypropylene allowing a visible indication of the tank water level. If necessary, the water storage requirements can be supplied by multiple tanks installed in parallel. The tank  3  can be configured to automatically refill through the tank supply line  6  using a connection to the domestic water supply  25 . An air vent sufficiently sized to relieve pressure during refill can be provided in the top of the tank (one inch diameter hole). The controller assembly  2  can provide power to an electrically operated solenoid  12  that will allow water flow when the float  26  in is the down (closed) position. The float  26  can employ multiple contacts to provide low/high water level alarms in addition to the automatic fill feature. The float circuit can be wired to the controller assembly  2  through the junction box  27 . The tank discharge line  6  can be constructed of one and one-quarter inch copper pipe and can contain a capped half-inch tank drain valve  48  for system maintenance or access to emergency sanitation water. The pump  11  inlet can be located below the full water level of the tank (one foot minimum off floor) assuring self priming of the pump  11 . The tank  51  can be sized to completely provide the required water volume or can be used as a break-tank assembly. In a break-tank design, the required water volume is met by the existing water supply automatically supplementing the stored water supply volume. 
     In various embodiments, the tank  3  can be, for example, 32″×86″ tall, cylindrical in shape, and supply a discharge capacity of 270 gallons. The tank can have a 12″ Diameter vented threaded top and a bulkhead fitting for the auto fill. A ¾″ CPVC fill line can be piped to the top of the tank from the domestic supply and terminate with a Hudson automatic fill valve installed just inside the tank. This line can be configured to have no separate shutoff. This configuration can provide an automatic means to keep the tank full of water. A 1.25″ bulkhead fitting installed at the bottom on the side of the tank using two rubber washers (on inside and outside) and terminating at the 1.25″ CPVC female adapter supplied with the pump assembly. A 0.5″ tee and drain valve can be installed at the point where the bulkhead exits the side on the pump suction line for maintenance. This design eliminates the shut-off valve currently installed in the suction line eliminating the possibility of catastrophic failure caused by a suction isolation valve is left in the closed position. The position of the pump suction below the water level means that the pump will always have the positive static head that is required for the proper operation of a centrifugal pump. The vent plug installed in the top of the pump casing is intended for manual priming of the system. A ¼″×10′ SS vent hose shall be connected from that port and discharge to the top of the tank with a ⅛″ nipple this line will perform the dual function of automatic priming the pump and provide circulation to keep the pump from overheating. 
     Alternatively, embodiments can be designed to take advantage of an existing municipal water supply or well system of unknown residual flow capacity. In cases where the house has a connection to the municipal water supply that meets the system  100  water supply requirements, a tank-less system may be used. However, the inventor of the present invention has found that a pump/break tank can provide consistent water supply for system  100  demand.

Additionally, the loss of power in any phase, and high/low water level can also provide a trouble signal. In at least one embodiment, all trouble signals will concurrently operate the red LED  33  and de-energize a kitchen lighting circuit. This is intended to provide supervision of all system critical functions. A transformer can provide a safe low voltage control for the tank float  26  control circuit. A momentarily closed motor stop switch  30  can be provided which is designed to return the system the fully automatic mode after testing.
