Abstract

In a remote controlled door lock system, a door lock apparatus transmits a confirm signal wirelessly upon controlling a door lock device thereof to operate in a selected one of the armed and disarmed states. A remote controller has a receiver circuit for receiving the confirm signal transmitted by the door lock apparatus, and an indicator unit for generating an indicator signal when the remote controller receives the confirm signal from the door lock apparatus.

Claims

1. A remote controlled door lock system, comprising:

a remote controller including a controller circuit and a first transmitter circuit coupled electrically to and controlled by said controller circuit so as to transmit a control signal wirelessly; and

a door lock apparatus including a first receiver circuit for receiving the control signal transmitted by said first transmitter circuit, a lock control circuit coupled electrically to said first receiver circuit so as to receive the control signal therefrom, a door lock device coupled electrically to and controlled by said lock control circuit to operate in a selected one of armed and disarmed states in response to the control signal from said first receiver circuit, and a second transmitter circuit coupled electrically to and controlled by said lock control circuit to transmit a confirm signal wirelessly upon controlling said door lock device to operate in the selected one of the armed and disarmed states;

said remote controller further including a second receiver circuit for receiving the confirm signal transmitted by said second transmitter circuit, said controller circuit being coupled electrically to said second receiver circuit so as to receive the confirm signal therefrom;

said remote controller further including an indicator unit coupled electrically to and controlled by said controller circuit to generate an indicator signal in response to the confirm signal from said second receiver circuit.

2. The remote controlled door lock system of claim 1, wherein said indicator unit includes a lamp indicator.

3. The remote controlled door lock system of claim 2, wherein said lamp indicator is a light emitting diode.

4. The remote controlled door lock system of claim 1, wherein said indicator unit includes a sound generating unit.

5. The remote controlled door lock system of claim 4, wherein said sound generating unit is a buzzer.
