Alarm.com ADC-200M-EV-E-DONG

The Alarm.com ADC-200M-EV-E-DONG is a replacement ethernet dongle for Alarm.com dual-path communicators. Any Alarm.com dual-path compatible module comes with an ethernet dongle included. Compatible modules include any dual-path SEM as well as the dual-path Interlogix modules. The dongle allows the installer to connect a wired ethernet cable to the communicator. This provides a dual-path configuration, allowing both IP and Cellular communication to be used. In the event that the original ethernet dongle is lost or damaged, this is the replacement.

Alarm.com dual-path communication works a bit differently to some other services. When dual-paths are available, Alarm.com communication modules send all signals via both paths simultaneously. Whichever signal reaches the Alarm.com server first, that signal is processed by the server. The signal received second is discarded. The server can tell when a signal is a duplicate of a signal already received, or a brand new signal. By handling communication this way, Alarm.com ensures that the fastest available communication path is always used. When a system is installed in a location with an internet connection available, it is always best practice to use that connection whenever possible.
