The ALARM INTERFACE from Doug Fleenor Design allows an emergency system to trigger a pre-recorded emergency DMX512 backup look. In normal operation, the ALARM INTERFACE passes DMX512 signals untouched. While triggered, the incoming DMX signal is disconnected and the ALARM INTERFACE sends the emergency backup look. The emergency backup look can be set to any lighting levels required by the installer.
