1.1.6 Operation & Alarm Unit (OAU)
The Operation & Alarm Unit (OAU) provides a visible and audible alarm in the event of a VDR-100G2
error condition. Using an output connection to a vessel’s central bridge alarm system, the OAU alerts an
Integrated Bridge System (IBS) of any VDR-100G2 system failures or error conditions. The alarm unit is
also used to initiate an IMO required download operation on the VDR-100G2.
The OAU has three (3) primary functions:
Alert the ship’s officer on watch of any detected failure within the VDR-100G2.
Allow a user to secure recorded data. This action must be taken within 24 hours of any incident
to prevent the recording of the incident from being overwritten.
Allow a user to connect or disconnect, as well as copy secured data, to the optional RSM.
The unit has a simple menu interface which allows a user to secure the recorded data and enable or
disable the optional RSM. It is equipped with:
Audible and visual alarm indicators
A 12-button keypad
A 4 x 20 character LED
An output for monitoring in a central alarm system
