What is the difference between Panic and Alert?

Panic
The Panic button provides an instant way for staff members to call for help from their safety team. Staff members can individually notify their safety administrators about localized issues (e.g. Medical Attention, Threatening Altercations, Substance Abuse, and Unwanted Contact). 

Alert
The Alert tool provides an organization-wide or school-wide notification with an audible tone. An Alert is used to warn your entire organization or building of a serious threat or safety issue. Depending on permission settings, both staff and administrators can send an alert (e.g. School Lockdown Events, Fires, and Severe Weather).
