The Cabin Panel is installed in all navigation officers’ quarters and in public areas. The
Cabin Panel releases audible and visual alarms if the OOW did not confirm presence
on the bridge within the selected watch time interval. A total of 12 Cabin Panels can
be installed.
DUTY LED
The DUTY LED is illuminated (in green) when the BNWAS is active and according to
type of Cabin Panel:
• Cabin Panel set as Captain, Backup Officer or Public is illuminated in all phases of
the watch alarm.
Note: The LED is disabled when a 4-core cable (MPYC-4 or equivalent) connects
Cabin Panel(s) to the Processor Unit.
ALARM LED
The ALARM LED lights (in red) and the buzzer sounds in response to an alarm sent
to the 2nd and 3rd stages.

The TEST switch checks the LEDs and the buzzer for correct operation. The connec-
tion between the Cabin Panel and Processor Unit is also checked. (This check is not
available when those units are connected to each other with a 4-core cable.) See
