4. The self-configuring sensor of claim 1 , wherein the processor-executable instructions that cause the sensor to determine an installation configuration comprise instructions that causes the sensor to: determine that the sensor is in a first installation 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.
5. The self-configuring sensor of claim 1 , wherein the processor-executable instructions that cause the sensor to determine an installation configuration comprise instructions that causes the sensor to: determine that the 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.
6. The self-configuring sensor of claim 1 , wherein the processor-executable instructions further comprise instructions that causes the sensor to: determine that the sensor has been powered on; and in response to determining that the sensor has been powered on, determine the installation configuration.
7. The self-configuring sensor of claim 1 , wherein the processor-executable instructions further comprise instructions that causes the sensor to: transmit a signal to a central control panel indicative of the installation configuration after the sensor has determined the installation configuration.
