This column indicates the severity level of the alarms for this site/location as a bar graph. The graph color codes each severity type.

Select a color on this bar graph to filter and view the alarms of the selected severity. The filtered alarms are displayed in Alarm Details screen. |

Site Health |
This column indicates a calculated value that indicates the site's health and displayed on a graph. Site health is calculated using the threat index of each alarm raised in the site and includes the alarms from all the floors in the site. When calculating Site Health, the threat index of the topmost alarms in the site are used. For example, for a site where alarms of the categories Severe, Critical, Minor are present, only the threat indexes of all alarms of Severe category are considered for calculating the Site Health. Other alarms are ignored. When you acknowledge an alarm, the threat index of that alarm is not included when calculating the Site Health in the next iteration of Site Health calculation. |
