The ACR OLAS Exposure Series N2K serves as a comprehensive safety solution for recreational and commercial boating, functioning as a man overboard alarm, wireless engine kill switch, or both. It connects directly to NMEA 2000 networks on motor and sail vessels, broadcasting alerts that trigger compatible chart plotters, multifunction displays, and MOB devices. This ensures the crew receives simultaneous visual, audible, and positional data during a man overboard event, with the MOB location automatically marked for quick return.

Installation involves a simple NMEA 2000 drop cable and engine connection, compatible with a wide range of marine electronics. Operators can equip multiple crew with T2 tags in Crew Tag Mode for alerts without engine cutoff, ideal for rescue operations, or use Helm Tag Mode on smaller motorboats under 35 feet as a proximity-based kill cord. The system restarts the engine after 5 seconds for passenger safety, and the included stainless steel control switch simplifies setup.

For solo boaters, the OLAS app's Solo Mode sends automatic distress SMS with vessel details to emergency contacts when offshore connectivity is available. TrackBack features generate arrows and distances to the last seen MOB position, while pre-formatted VHF scripts streamline mayday calls, enhancing coordination with rescue services in marine safety scenarios.
