I thought OpenCPN could trigger this 'alarm'. Douz wrote about 'AIS Alarm' so I assumed there is some sort of alarm.
What about the geofence node ( https://www.npmjs.com/package/node-red-node-geofence ). Haven't looked into it but this might be an option to check if an AIS target is in your 'alarm' area.
I guess you can calculate the CPA with node-red but it's not that simple
