Within the 'Groups' tab you can create multiple groups that can be alarmed separately. Click on 'Add' to create a group. Within the screen that follows you can enter the desired name for the group and, optionally, make it location specific. After entering a name, the group can be saved.

In the screen that follows you can appoint your users to one or more groups; you can always edit this later.

Existing groups can be edited by clicking the pen icon next to the group name. You can change the name, users and toggle the 'location specific' setting here.
