A residential dwelling unit fire protection system for a residential dwelling unit. The fire protection system includes a pressurized liquid supply, a pressurized gas supply, a control valve coupled to the liquid and gas supplies, a network of pipes coupled to the control valve and the pressurized gas supply, a pressure sensor, an alarm, a fire detection device, a releasing control panel, and a quantity of residential fire sprinklers to protect the residential dwelling unit. The control valve is normally in a closed position and can be single interlocked with other devices to prevent liquid flow through the control valve. Each of the quantity of residential fire sprinklers is coupled to the at least one pipe so that the control valve can be pre-actuated by the releasing control panel based on at least one of the pressure sensor or the fire detection device.
