Systems and methods for providing frequency diversity in security transmitters

A method of transmitting communication messages by a security sensor device in a wireless security system, the method comprising:

• providing a security sensor device having a sensor capable of generating a status signal, a microcontroller coupled to the sensor and capable of generating a communication message for transmission at a first frequency and a communication message for transmission at a second frequency, and a multiple frequency transmitter coupled to the microcontroller that can transmit the communication message at the first frequency and the communication message at the second frequency;
• monitoring an area to be secured for a status change with the sensor;
• generating the communication message for transmission at the first frequency and the communication message for transmission at the second frequency based on the status change with the microcontroller;
• transmitting the communication message at the first frequency and the communication message at the second frequency with the multiple frequency transmitter.

A method of receiving communication messages by a receiving device in a wireless security system, the method comprising:

• providing a receiving device having a receiver module capable of receiving a communication message transmitted at a first frequency and a communication message transmitted at a second frequency, and a controller module coupled to the receiver module and having a system controller for generating one or more instruction signals,
• receiving the communication message at the first frequency or at the second frequency;
• validating the received communication message with the receiver module;
• processing the received communication message with the controller module;
• creating and sending one or more instruction signals based on the received communication message.
