If Fall Detection is enabled, the device will use its onboard sensors to detect when a fall has occurred.

If a fall is detected, the device sensors will register it and wait 10 secs to detect further movement. Then, a voice will announce that a fall has been detected. You can cancel the alert by pressing both the SOS and power buttons together.

If, after 10 seconds, the alarm has not been cancelled, the device will raise an SOS alert.

See here for how to deal with a false alert.

Please get in touch with your organisation's Account Owner to find out if you have Fall Detection enabled.
