ALARM SYSTEM NETWORK OPERATION

Various embodiments are directed to network controllers coordinating operation of alarm panels, and to an alarm network incorporating multiple alarm panels that each incorporate such a network controller and aspects of the coupling and interactions of those alarm panel components enabled by interactions among those network controllers. An alarm panel includes an alarm controller configured to monitor one or more points for an indication of an alarm condition and a network controller. The network controller includes a proxy server configured to present multiple proxies on an internal network and to receive multiple unicast packets, each proxy of the multiple proxies associated with an alarm panel of multiple alarm panels and each unicast packet of the multiple unicast packets directed to one of the proxies of the multiple proxies; and a multicast component to combine the multiple unicast packets received within a specified interval of time into a multicast packet.
