Alarm transfer system

  28 The system should immediately warn the master and the appointed back-up navigator when a proper acknowledgement has not been made.

  29 Proper acknowledgement of any alarm in the alarm transfer system should automatically reset the interval checking system. The system should have a device to give the officer of the navigational watch advance warning of the expiry of the time interval.

  30 Acknowledgement of alarms should only be possible on the bridge.

  31 The alarm transfer system should be continuously powered and shall have an automatic change over to a stand-by power supply in case of loss of normal power supply.

  32 The requirements of paragraphs 18 to 32 are not intended to prevent Administrations from authorizing trials with any technical systems that adequately verify the alertness of the officer of the navigational watch at intervals up to 12 minutes.
