# Alarms

In this subsection, a table is presented that showcases all active alarms and/or alarms that have occurred within the selected time period.

Using the time bar, a precise time interval can be set in terms of the start and end of alarm activation.

Activating the "active alarms" option displays only active alarms in *real time*.

Using the appropriate filters, it is possible to view the list of specific alarms by, for example, program type, machine type, recipe type, etc. Applying filters allows to investigate at a first glance any recurring conditions associated with certain alarms: one alarm code may be more frequent during a specific program, another during a certain operator's shift, and so on.

If provided, it is possible, for each alarm recorded, to access the [Black Box](https://40factory.gitbook.io/mat-webapp-1/2.14.1/basic-mat-modules/machine-recorder) section by clicking on the "expand" icon in the last column on the right of the dashboard: in this way it is possible to observe the behavior of process variables and machine events that occurred in the time frame of alarm activation.
