Abstract
A packaged residential fire pump system for sprinkler protection of one- and two-family dwellings. The system independently provides sufficient water pressure, and volume, for a two sprinkler flow for a period of time. An existing domestic water supply is supplemented with a dead water storage tank. The system can be combined with hydraulically sized, or scheduled, system piping and sprinkler heads.
Claims17
A packaged residential fire sprinkler pump system, comprising:
- a fire sprinkler controller assembly operably coupled to an existing water and electrical supply;
- a fire sprinkler pump/motor assembly operably coupled to existing water and electrical supplies;
- a system control piping assembly for operation and maintenance of the fire sprinkler pipe system;
- and
- a welded support frame assembly supporting the pump/motor assembly, the controller assembly, and the control piping assembly, the support frame being constructed for wall mounting using an interlock assembly,
- wherein the fire sprinkler controller assembly further comprises
- a system three pole rotary disconnect;
- a motor disconnect;
- and
- an external control circuit breaker whose position is electrically supervised using a plurality of contacts and relays configured to supervise system critical functions, including
- to output a first trouble signal when said external control circuit breaker is in an off position,
- to output a second trouble signal upon loss of power in any phase, and
- to output a third trouble signal upon high or low water level thresholds being exceeded, and
- wherein each said trouble signal is operably coupled to a red Light Emitting Diode LED and a kitchen lighting circuit such that output of an of said trouble signals causes the red LED to be illuminated and de-energizes the kitchen lighting circuit.

A packaged residential fire sprinkler pump system, comprising:
- a fire sprinkler controller assembly operably coupled to an existing water and electrical supply;
- a fire sprinkler pump/motor assembly operably coupled to existing water and electrical supplies;
- a system control piping assembly for operation and maintenance of the fire sprinkler pipe system;
- and
- a welded support frame assembly supporting the pump/motor assembly, the controller assembly, and the control piping assembly, the support frame being constructed for wall mounting using an interlock assembly,
- wherein the control piping assembly further comprises
- a one-inch piping outlet supplying water to a sprinkler system;
- a drain/test assembly for testing system readiness and constructed to allow water flow through a slow closing gate valve to an open sprinkler having its operating element retaining screw removed, the open sprinkler being threaded into a single outlet half-inch white rectangular cluster cover mounted on an exterior of a dwelling using brick insert screws or a small plastic siding box;
- and
- a one-quarter inch circulation line constructed to allow a cooling water flow through the test/drain assembly when the pump is operating against a closed system.

- a fire sprinkler pump/motor assembly operably coupled to existing water and electrical supplies;
- a system control piping assembly for operation and maintenance of the fire sprinkler pipe system;
- and
- a welded support frame assembly supporting the pump/motor assembly, the controller assembly, and the control piping assembly, the support frame being constructed for wall mounting using an interlock assembly,
- wherein the support frame assembly further comprises
- a mounting frame assembly connecting the pump/motor, controller assembly, and system control piping assembly to a welded frame constructed from minimum fourteen gauge slotted angle stock having dimensions of two and one-half inch by one and one-half inch and primed and painted red to resist corrosion;
- and
- an interlocking wall mounting system constructed of two pieces of thirteen-sixteenth inch steel strut and configured for mounting the frame on a wall,
- wherein the mounting frame assembly is designed to allow for installation of an R-13 insulation barrier and a thermal barrier between a mounting surface and wetted components of the packaged residential fire sprinkler system to prevent freezing of the control piping assembly and to provide insulation values required by energy codes on exterior walls.
