Navitron NT990 BNWAS is type Approved by GL, RMRS & CCS for full compliance with IMO Resolution MSC. 128(75) & IEC 62616 (GL), the Navitron NT990BNWAS is available as a basic system to operate proprietary alarm units etc. (if appropriate) or, as an expanded system complete with selector units, remote resets including movement detectors and individual cabin and /or
crew call audible alarms. The resultant alarm system provides a regulation safety monitor requiring regular acknowledgement (Reset) by the duty watch personnel at selectable time intervals between 3 and 12 minutes.
Once activated, completion of the specified timeout period (3-12 mins) will automatically generate a Bridge visual alarm (15 secs) followed by a Bridge audible alarm (15 secs) which is tone and volume adjustable during installation. Alarm cancellation and commencement of a new timing period will occur whenever the BNWAS ‘Reset’ button is operated on the main unit or other Wheelhouse/Bridge located Reset units. These can include those available from proprietary equipment workstations (Radar / ECDIS etc. ) and the Central Alarm Panel.
Failure to ‘Reset’ the system during the 30 second Bridge visual/audible alarm period will result in automatic ‘Officer Call’ alarm activation which, if not acknowledged within a maximum period of 3 minutes, will automatically be followed by the generation of ‘Crew Call’ alarms. In the event of a sudden crisis situation requiring immediate Officer assistance, the NT990BNWAS also features an ‘Emergency Call’ facility which may be operated at any stage of the timing cycles.
