Fully compliant with Resolution MSC.128(75) and BSH (Germany) Type Approved, the Navitron NT990BNWAS requires regular acknowledgement (Reset) by the duty watch personnel at time intervals between 3 and 12 minutes which can be specified and set by the master or OOW as required.
The chosen time interval (3 - 12 mins) is security protected by means of key switch selection as is the operating mode which may be set: -
Permanently ON
Permanently OFF
AUTO mode (automatically activated by power up of other equipment such as Autopilot / Track Control system etc)
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.
