HLD-BNWAS 600 Bridge Navigational Watch Alam System

The BNWAS works on the basis of the logic sequence stipulated in IMO resolution MSC.128(75) and IEC 62616 whereby the officer of the watch (OOW) needs to periodically press a button to reset a countdown sequence. At the end of that sequence,called the "dormant period", which is selectable from 3 to at almost 12 minutes, the BNWAS flashes ligths in the bridge wheelhouse. The OOW then has 15 seconds to pressure the reset button. If he fails to do so, an audible alarm is sounded, just in the wheelhouse. He then has 15 more seconds to press the reset button. If he still does not, a "2nd stage" alarm is triggered whereby loud alarms are emanated by small speaker devices fitted in the back up officer's and /or master's cabins. Finally there is a "3rd stage" alarm in which even more speaker devices, located in the cabins of additional crew members, sound off. 3rd stage alarming happends when the system is not reset during the first 90 seconds of the 2nd stage alarming.
