A remotely-actuated residential water supply cut-off system is disclosed. A remotely-actuated cut-off valve interposed in a residential water line downstream of a pressure-reducing valve. An electronic actuator is mounted on the cut-off valve and is remotely actuated to drive a DC motor in a clockwise or counterclockwise direction to open or close the cut-off valve in response to a received signal. The electronic actuator includes a transceiver, a microcontroller and a motor. The microcontroller drives the motor to open or close the valve in response to a wireless signal received by the transceiver. A handheld transceiver unit sends a signal to the actuator to open or close the cut-off valve, or operate in automatic mode.

What is claimed: 1. A remotely-actuated residential water supply cut-off system for integration with a home security system comprising: a remotely-actuated cut-off valve interposed in a residential water line downstream of a pressure-reducing valve; an actuator including a transceiver and mounted on the cut-off valve and remotely actuated to open or close the cut-off valve in response to a wireless signal received by the actuator transceiver; and a wireless adapter unit, including a transceiver and microcontroller, integrated with the home security system and located remotely from the actuator for sending a signal to the actuator to close the cut-off valve when the home security system is armed, and a signal to return the cut-off valve to an initial position when the security system is disarmed. 2. The remotely-actuated residential water supply cut-off system of claim 1 further comprising a handheld unit including a radio frequency (RF) transceiver for transmitting an open or close signal to the actuator to control a position of the cut-off valve when the home security system is disarmed. 3. The remotely-actuated residential water supply cut-off system of claim 2 wherein the handheld unit further includes a microcontroller to generate the open or close signal, an LCD panel and an oscillator to provide a frequency of operation to the microcontroller. 4. The remotely-actuated residential water supply cut-off system of claim 3 wherein the LCD panel provides an indication of a current position of the cut-off valve. 5. The remotely-actuated residential water supply cut-off system of claim 1 wherein the actuator comprises, a microcontroller, a DC motor, a motor control and a power supply converter circuit. 6. The remotely-actuated residential water supply cut-off system of claim 5 wherein the actuator microcontroller sends a signal to the motor control to control a movement of the DC motor to open or close the cut-of valve. 7. The remotely-actuated residential water supply cut-off system of claim 1 wherein the cut-off valve is interposed downstream of both the pressure reducing valve and a water line connected to a residential sprinkler system. 8. The remotely-actuated residential water supply cut-off system of claim 5 wherein the actuator includes a switch that controls manual and remote operation of the cut-off valve. 9. An electronically controlled apparatus for use in a remotely-actuated residential water supply cut-off system, comprising: a valve interposed in a residential water line in a location that is downstream of a pressure-reducing valve; an electronic actuator mounted on the valve and including a transceiver, a microcontroller and a motor, wherein the microcontroller drives the motor to open or close the valve in response to a remotely transmitted wireless signal received by the transceiver; and a wireless adapter, including a transceiver and microcontroller, integrated with a home security system and located remotely from the electronic actuator for transmitting a signal to the actuator to remotely control the position of the valve both when the home security system is activated and deactivated. 10. The electronically controlled apparatus of claim 9 wherein the valve is inserted in the residential water line downstream of a water line connected to a residential sprinkler. 11. The electronically controlled apparatus of claim 9 wherein the remotely transmitted wireless signal received by the transceiver is a radio frequency (RF) signal transmitted by a handheld remote control device to open or close the valve. 12. The electronically controlled apparatus of claim 9 wherein the electronic actuator further comprises a motor control to control a movement of the motor to open or close the valve. 13. The electronically controlled apparatus of claim 9 wherein the electronic actuator further comprises a switch that controls a manual and remote operation of the valve. 14. The electronically controlled apparatus of claim 9 wherein the electronic actuator further comprises a power supply converter circuit. 15. The electronically controlled apparatus of claim 9 wherein the valve comprises a ball valve. 16. The electronically controlled apparatus of claim 9 wherein the electronic actuator further comprises a valve travel limit switch. 17. The electronically controlled apparatus of claim 12 wherein the motor control sends a signal to the microcontroller when the motor is overheating. 18. The electronically controlled apparatus of claim 9 wherein a residential flood free zone is provided by the valve when the valve is in a fully-closed position.
