Alarms

Alarms are notifications that you create, signaling when conditions have gone outside defined operating guidelines.  You can create alarms to signal when tank volumes are too low, pressures are too high, motor rpm are too fast, etc.

When an alarm condition occurs, that fact will be recorded. The alarm itself can be acknowledged or silenced, but the history of the alarm’s occurrence will remain.

Alarm notifications are primarily displayed in the upper right corner of the screen.  A flashing red bar and an audible two-tone warning are the first indications that an alarm has occurred.  In addition, you can create visible indicators that will display within the page to indicate where in the system an alarm is occurring.  Pop-ups can be created to force operators to acknowledge critical alarms.

Also, the alarm history can be displayed within any page, showing the details of any alarms that occur.  VTS also provides an alarm dial-out feature that allows the system to send a pre-recorded voice message to the telephone of an off-site operator.

Alarms are managed with the Alarm Page – a standard page in any VTS application.  On this page, any operator (possessing sufficient security rights) may review, acknowledge or silence alarms.
