Abstract: A system for transmitting and receiving communication messages in a wireless security system is provided. The security system comprises one or more security sensor devices and a receiving device. Each security sensor device is capable of monitoring a status change in an area and is capable of generating and transmitting a communication message at a first frequency and a communication message at a second frequency based on a change in status of the area being monitored. The receiving device capable of receiving the communication messages from the one or more security sensor devices and in response thereto is capable of generating one or more instruction signals based on the communication messages. A security sensor device of the one or more security sensor devices transmits the communication message at least one time at the first frequency and the communication message at least one time at the second frequency.

Abstract: A system that provides security communication processes in a security system is provided. The system has a digital signal processor (“DSP”), a memory portion and a coder/decoder (“CODEC”). The DSP implements a plurality of different communication processes. The memory portion has a plurality of communication algorithms that implement a corresponding communication process within the DSP. The CODEC is connected to the DSP to convert analog signals into digital signals prior to being sent to the DSP and to convert digital signals sent from the DSP into analog signals. The DSP is connected to the memory portion to enable retrieval of the at least one communication algorithm for use in implementing the corresponding communication process.
