5. The self-configuring sensor of claim 1 , wherein the processor-executable instructions further cause the processor to determine that the self-configuring sensor is in a first installation configuration when the processor detects a state change in the first sub-sensor and that no state change has been detected in the second sub-sensor.
6. The self-configuring sensor of claim 1 , wherein the processor-executable instructions further cause the processor to determine that the self-configuring sensor is in a multi-sensor configuration when the processor detects a state change in the first sub-sensor and a state change in the second sub-sensor.
7. The self-configuring sensor of claim 1 , wherein the processor-executable instructions further comprise instructions that causes the self-configuring sensor to:
determine that the sensor has been powered on; and
in response to determining that the sensor has been powered on, determine whether the self-configuring sensor is installed on the door or the window the installation configuration.
8. The self-configuring sensor of claim 1 , wherein the processor-executable instructions further comprise instructions that causes the self-configuring sensor to transmit a signal to a central control panel indicative of the whether the self-configuring sensor is installed on the door or the window.
9. The self-configuring sensor of claim 1 , wherein the memory further stores a sensor identification code, and the processor-executable instructions further comprise instructions that causes the self-configuring sensor to modify the sensor identification code after the processor determines whether the self-configuring sensor is installed on the door or the window.
10. The self-configuring sensor of claim 9 , wherein the processor-executable instructions further comprise instructions that causes the self-configuring sensor to transmit the modified sensor identification code to a central control panel after the self-configuring sensor has determined whether the self-configuring sensor is installed on the door or the window.
11. A method, performed by a self-configuring sensor having a first sub-sensor, a second sub-sensor, and a processor in communication with the first sub-sensor and the second sub-sensor, comprising:
determining, by the processor, based on signals received from both the first sub-sensor and the second sub-sensor whether the self-configuring sensor is installed on a door or a window.
12. The method of claim 11 , further comprising monitoring, by the processor, the first and second sub-sensors for detecting changes in a first sub-sensor state and a second sub-sensor state, respectively.
13. The method of claim 11 , wherein the first sensor comprises a reed switch and the second sensor comprises a mechanical switch.
14. The method of claim 11 , further comprising, subsequent to the processor determining whether the self-configuring sensor is installed on the door or the window, selecting, by the processor, either the first sub-sensor or the second sub-sensor to determine an open/closed status of the door or window and transmitting, by a transmitter coupled to the processor, an alarm signal only if the selected sub-sensor changes state.
15. The method of claim 11 , further comprising determining, by the processor, that the self-configuring sensor is in a single sensor configuration when the processor detects a state change in the first sub-sensor and that no state change was detected in the second sub-sensor.
16. The method of claim 11 , further comprising determining, by the processor, that the self-configuring sensor is in a multi-sensor configuration when the processor detects a state change in the first sub-sensor and a state change in the second sub-sensor.
17. The method of claim 11 , further comprising determining, by the processor, that the self-configuring sensor has been powered on and, in response to determining that the self-configuring sensor has been powered on, determining by the processor whether the self-configuring sensor is installed on the door or the window.
18. The method of claim 11 , further comprising transmitting, by a transmitter coupled to the processor, a signal to a central control panel indicative of whether the self-configuring sensor is installed on the door or the window.
19. The method of claim 11 , further comprising storing a sensor identification code in a memory coupled to the processor and modifying the sensor identification code after the processor determines whether the self-configuring sensor is installed on the door or the window.
20. The method of claim 19 , further comprising transmitting, by a transmitter coupled to the processor, the modified sensor identification code to a central control panel after the processor has determined whether the self-configuring sensor is installed on the door or the window.
