The Furuno BR-500 BNWAS is a Bridge Navigational Watch Alarm System designed to improve marine safety by monitoring the officer on watch (OOW) on the ship’s bridge.
The BR-500 ensures that the watch officer remains alert and active while the vessel is underway.
It detects:
- Lack of movement on the bridge
- No interaction with navigation equipment
- Possible officer incapacitation (fatigue, illness, etc.)
If no response is detected, it triggers alarms to prevent accidents.
