SIA-2000协议构成了控制器和中央站接收器之间的通信。这种通信的基本形式传递报警、报警取消、故障和恢复等信息。这涉及将信息记录从控制传输到中心站，并从接收器接收每条记录的确认。为了支持远程面板编程和通过音频或视频方式进行报警验证等功能，该协议提供了扩展通信会话的条款。一旦扩展，接收器可以查询控件的信息或更改控件的配置。扩展会话也可用于验证。正是在这一点上，使用SIA-2000的通信结束，用于验证的适当通信形式开始。

The SIA-2000 protocol structures the communication between a control and a central station receiver. The basic form of this communication conveys information such as alarms, alarm cancels, troubles, and restorals. This involves tranfsferring information records from the control to the central station, and receiving acknowledgements from the receiver for each record.To support features such as remote panel programming and alarm verification through audio or video means, the protocol has provisions to extend the communication session. Once extended, the receiver can query the control for information or change the control's configuration. The extended session can also be used for verification. It is at this point, that communication using SIA-2000 ends and the appropriate form of communication for verification begins.
