13.1 Interfacing requirements for alert-related communication

  13.1.1 The communication protocol should allow the implementation of the functions described in these standards.

  13.1.2 The alert-related communication should follow a standardized concept to provide the following functions and operations:

  • .1 unique identification of an alert divided into cluster, function, alert code, time;

  • .2 distribution of alerts with its priority, state and text information;

  • .3 distribution of acknowledgement, silencing and other commands for alerts from different locations, including operator input and results of system processing;

  • .4 transmission of aggregated alerts with relevant information (e.g., number of alerts aggregated);

  • .5 proper reconnection after disconnection or power down at any time and in any alert condition with a result of a consistent alert presentation within recovery time; and

  • .6 standardized communication should be used. Individual subsystems may use an alternative internal concept.

13.2 Connection to the ship's power supply

  13.2.1 The CAM should be supplied from both the main and the emergency source of electrical power with automated changeover through a local distribution board with provision to preclude inadvertent shutdown.

  13.2.2 After an electrical power failure the system should restart automatically when the power is restored.
