Abstract: Methods and devices for a wireless security controller that is able to receive data transmissions over multiple frequency channels and decode security messages that use different data protocols is provided. The security controller monitors an incoming security message transmission from a security sensor. As the transmission is received, the security controller analyzes the data, and determines whether is encoded using one of two or more different transmission protocols. The security controller then completes reception and error-checking of the received security message, and processes the security message.
