• can cause an event, status, text, or a combination of status and text to result depending on
the configuration of the alarm
The following table provides a brief description of the various types of alarms available within
iControl.
Alarm Acknowledgement
Alarm acknowledgement is a feature that provides on-line live acknowledgement of alarms
from Web pages and the iControl Alarm Browser. Alarm acknowledgement provides a way of
communicating to operators who may not be located in the same location. When these
operators are viewing the same Web page, acknowledgement of an alarm is visible for all to
see.
When a channel within a group of channels has an alarm status that is not normal then the
group background turns red, and the affected individual channel button flashes red until the
alarm is acknowledged. When acknowledged the alarm changes to solid red.
If the affected individual channel clears before being acknowledged, the group background
changes to a color designated by your configuration team that represents normal status and
the individual channel button flashes green.
An alarm acknowledgement:
• causes the alarm to flash at all locations when the alarm status changes from normal status
to any other status
• causes the alarm to continue to flash until acknowledged
• can indicate that somebody is working on resolving specific issues that caused alarms
when acknowledgment occurs
• simultaneously acknowledges all sub-alarms associated with a virtual alarm that represent
channel paths or groups of channels when the virtual alarm is acknowledged
• also allows one-by-one acknowledgement of virtual alarm sub- alarms
