In certain situations, you may want an audible indication of a change in alarm state. The Alarms List page has the optional ability to generate a sound either when new alarms are created, or on each change to an alarm event count on the page.
The alarm sound feature is disabled by default. A system administrator must activate the sound feature, and can define default sound settings for all users. Users can modify the default sound settings for the duration of their session via a drop-down list with the following options:
Sound Off: No sounds will be generated from the page.
Sound On New Alarm: Sounds will be generated for every new alarm on the page.
Sound On New Alarm Count: Sounds will be generated for every increase in the alarm event count for alarms on the page. This may result in many sounds being played.
By default, the Alarms List page displays acknowledged and unacknowledged alarms in separate search tabs. In your operational environment, however, it may be useful to see all alarms on the same page, with unacknowledged alarms flashing to indicate that a team member has not yet acknowledged them. This lets everyone see the real-time status of all alarms, and highlights those that still need attention.
Unacknowledged alarms flash steadily. Alarms that have been acknowledged do not flash, and have a small tick beside their ID numbers. You can select multiple alarms to escalate, clear, acknowledge, or unacknowledge by checking the associated Ack boxes.
