FLUID CONTROL ASSEMBLIES FOR SPRINKLER SYSTEMS
Automatic fluid control assemblies and methods for fire protection include an arrangement of electrically operated control points, a valve body and a controller to operate the fluid control assembly. The automatic fluid control assembly has an inlet, an outlet and a valve body to control flow between the inlet and the outlet. An electric latch includes a first electrically operated control point and a second electrically operated control point in fluid communication with a control line to control the flow of fluid from the inlet to the valve body and outlet. The methods of fluid control includes controlling a plurality of electrically operated control points to perform any one of: a leak test, a trip test, a flow test, a water delivery test, and a validation test of a non-trip condition and a trip condition.
1 - 78 . (canceled)
79 . A fire protection control system, comprising:
a first valve coupled with a fluid supply;
a sensor to detect a pressure on an outlet side of the first valve;
a second valve coupled with a port of the first valve;
a third valve coupled with a vent and with the second valve; and
a controller comprising one or more processors to:
determine, based on the pressure detected by the sensor corresponding to a fire condition, to cause operation of the first valve; and
provide a control signal to cause the second valve to open to allow for fluid from the fluid supply to flow through the first valve to one or more sprinklers.
80 . The fire protection control system of claim 79 , comprising:
the second valve to open into an open state to allow for fluid from the fluid supply to flow through the first valve to the one or more sprinklers; and
a diaphragm chamber, the diaphragm chamber in a depressurized state with the second valve in the open state.
81 . The fire protection control system of claim 79 , comprising:
a diaphragm chamber; and
at least one of the first valve or the second valve including a latch configured to prevent fluid from pressurizing the diaphragm chamber.
82 . The fire protection control system of claim 79 , wherein the fire protection control system includes a dry pipe fire protection system.
83 . The fire protection control system of claim 79 , wherein the fire protection control system includes a preaction fire protection system.
84 . The fire protection control system of claim 79 , comprising:
the first valve including a solenoid valve.
85 . The fire protection control system of claim 79 , comprising:
the second valve including a solenoid valve.
86 . The fire protection control system of claim 79 , comprising:
the controller to transmit an electrical signal to control fluid flow through at least one of the first valve or the second valve.
87 . The fire protection control system of claim 79 , comprising:
a reset detector to detect heat corresponding to the fire condition; and
the reset detector coupled with the controller.
88 . The fire protection control system of claim 79 , comprising:
a fluid detector to detect fluid flow through an outlet of the fire protection control system.
89 . A fire protection control method, comprising:
coupling a first valve with a fluid supply;
coupling a second valve with a port of the first valve;
coupling a third valve with the second valve;
detecting, with a sensor, a pressure on an outlet side of the first valve;
determining, with a controller comprising one or more processors, based on the pressure detected by the sensor corresponding to a fire condition;
providing a control signal to cause the second valve to open to allow for fluid from the fluid supply to flow through the first valve to one or more sprinklers.
90 . The method of claim 89 , comprising:
opening the second valve into an open state to allow for fluid from the fluid supply to flow through the first valve to the one or more sprinklers, wherein a diaphragm chamber is in a depressurized state with the second valve in the open state.
91 . The method of claim 89 , comprising:
a diaphragm chamber;
at least one of the first valve or the second valve including a latch; and
preventing, via the latch, fluid from pressurizing the diaphragm chamber.
92 . The method of claim 89 , wherein the first valve is part of a dry pipe fire protection system.
93 . The method of claim 89 , wherein the first valve is part of a preaction fire protection system.
94 . The method of claim 89 , comprising:
the first valve including a solenoid valve.
95 . The method of claim 89 , comprising:
the second valve including a solenoid valve.
96 . The method of claim 89 , comprising:
transmitting, via the controller, an electrical signal to control fluid flow through at least one of the first valve or the second valve.
97 . The method of claim 89 , comprising:
detecting, with a reset detector, heat corresponding to the fire condition; and
the reset detector coupled with the controller.
98 . The method of claim 89 , comprising:
detecting, with a fluid detector, fluid flow through an outlet.
