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.
