5. Detection phases
Depending on the firmware version installed on the sensor, it is able to detect falls using different methods and functions.
Fall detection
Available function in all firmware versions of the sensor
The sensor goes through several detection phases to reliably detect and report a fall. Depending on the phase reached, a corresponding event is sent by the sensor. There are 2 phases and 3 events
Phases
After a person has fallen to the ground, it only takes a few seconds for the sensor to go into fall_detected.
If detection is complete after about 55 to 60 seconds and the fall has been confirmed, the sensor send the calling.
After the call has been made, the end of the detection phase is communicated and the detection process is ended as normal.
As soon as the person stands up or another person enters the room the fall detection stops with a normal event.
The entire detection process usually takes about 60 seconds (1 minute).

Fall test
The following procedure is possible to carry out a fall test:
- enter the detection area
- Walk around for 1-2 minutes
- go down slowly
- lay flat on your back
- Wait for the detection phases to pass
