# GroupAlarm - PNA-11

GroupAlarm PNA-11 allows your staff to trigger an SOS alarm at the touch of a button in the GroupAlarm PNA-11 app. This alarm is then immediately forwarded to the designated alarm groups. PNA-11 is an extension that you can add via `Admin` → `Extensions`. The free basic version already allows you to trigger SOS and voluntary alarms. Additional features such as inactivity alarms, fall detection and indoor tracking are part of PNA-11 Pro, which you can add via `Admin` → `PNA-11`.

|| ⚠️ You can configure which alarm templates are to be triggered by the PNA apps in GroupAlarm Things under Admin → Things. Information on `Things` is available [here](https://docs.groupalarm.com/en/article/groupalarm-things-11bxzmd/).

In the `Licences` section, you can manage your PNA-Pro licences. You can increase or reduce the number of licences at any time. You can also allocate licences to your participants.  

| 💡 Here, you can also reallocate licences using the tick boxes. This allows you, for example, to allocate licences individually depending on the shift.

In the `Indoor positioning` section, you define the access points in your Wi-Fi network to enable location tracking within the building. To do this, enter the relevant MAC address of the access point and specify its location. Whenever the PNA app is triggered, it always includes the MAC address of the access point to which the mobile phone is currently connected, as well as the corresponding coordinates.
