* '''Angle''' - this parameter defines the angle that needs to be exceeded for fall detection to start counting Alarm Delay. The zero point angle (zero vector) is updated every time the device goes from movement state 1 to 0. It is also updated just before going to sleep.

* '''Alarm Delay''' - this parameter sets time for how long the configured angle needs to be exceeded for the alarm event to trigger. The angle is checked every 1 second, so if during the alarm delay time the device is put back into vertical position (device angle is less than configured detection angle) the alarm delay resets.

* '''Active Time''' - amount of time that has to pass after movement goes from 1 to 0, before vector gets sstored and angle starts being checked.
* '''Active Time''' - amount of time that has to pass after movement goes from 1 to 0, before vector gets stored and angle starts being checked.
===Zero vector===
===Output Control===
It is an accelerometer vector, which is considered to represent a standing bike. . It gets stored as such when movement goes from 1 to 0 and stays 0 for the configured Active Time.
The feature allows to configure one of the digital outputs of the device for event alarm. This feature can be used together with buzzer to trigger sound alarm after the fall detection is triggered.
* '''DOUT ON Duration''' - sets time in milliseconds for how long DOUT should stay active after the fall is detected.
* '''DOUT OFF Duration''' - sets time in milliseconds for how long DOUT should stay inactive after the fall is detected.
===Zero Vector Explanation===
It is an accelerometer vector, which is considered to represent a standing bike. It gets stored as such when movement goes from 1 to 0 and stays 0 for the configured Active Time.
