INTRODUCTION
KW810 BNWAS is designed and made by AMI Marine conforming to the requirements of IMO resolution MSC.128 (75) Performance Standards.
It automatically monitors bridge activity via motion sensor and alarms can go to different stages up to activate SSAS distress system.
A BNWAS is a device which triggers an alarm if an Officer on Watch (OOW) becomes incapable of performing the OOW’s duties.
IMO had adopted resolution MSC. 128 (75) on performance stan- dards for a BNWAS.
Currently, there are two types of BNWAS, one requires the OOW to press a button to set interval (failure to do so triggers alarm), and the other detects movements of the OOW via motion sensor tech- nology (as long as the sensor finds movements of the OOW the alarm will not go off).
The BNWAS should be operational whenever the ship's heading or track control system is engaged, unless inhibited by the Master.
