# Viewing Alarm History

You can view the alarm history for a site on the Site Summary screen Alarms tab. By default the history bar chart shows the alarm count for the previous 24 hours but you can change the period in the alarm history filter.

# Trending Alarm History

To show the alarm history as a trend either:

- On the Alarm List (main list or site-specific list), choose the **Show in Site History** option from the alarm item menu. This shows the alarm history on the same chart as the important site trends.
- On the Alarm History Count panel, click the **Trend All** icon. This shows the alarm history on its own trend chart.
