Central Alert Management
Central Alert Manager (CAM) Watchmode is supported by VMFT, if
available. This will be as either a configurable option within a TotalWatch
system, or as a single watchmode (CAM-only node). The alarm system is a
functional alert interface which enables the operator to silence,
acknowledge and cancel alerts, from all nodes, centrally.
CAM Watchmode is a clear method for viewing all alerts, either from the
bridge or others received from other external equipment. The system is
flexible and configurable according to specific requirements.
The CAM uses the VMFT alert output to forward unacknowledged alerts
(alarms, warnings and cautions) to all nodes on the system, and to other
locations of the ship as necessary. Additionally, VMFT alert data can be
sent to external systems, often known as CAMs - this has to be configured
using "CAM" in the config tool.
Alarms and warnings are, where possible, arranged in groups, except
emergency alarms. The following types of alerts are not grouped:

Faults requiring speed or power reduction

Automatic shutdown of machinery

Steering gear alerts.
A group of alerts may be acknowledged at the same time. Alert priorities
include Emergency Alarm, Alarm, Warning and Caution, as described in
List of Alarms, Warnings and Cautions. Alerts are sorted by these priorities
and by time within each priority group. The indication of Alert status
(unacknowledged or acknowledged) is the same as described previously in
Alert Status and Alert Display.
The CAM displays a warning when NAVTEX messages are received via a
serial connection on the client node.
The CAM includes Shutdown function buttons (Shutdown or Restart
System) at the bottom of the window.
