If ''Crash Detection'' is enabled, it monitors acceleration on each axis which helps detecting an accident. ''Threshold'' and ''Duration'' values are set depending on the impact that is required to be detected. {{{model|FMB1YX}}} can detect events ranging between a slight tapping on the device (Threshold = 100 mG, Duration = 1 ms) and a severe accident (Threshold = 4000 mG, Duration = 5 ms).<br/>If ''Crash Trace'' is disabled a crash detection event will be generated (included into the sent record) only when scenario starts and finishes.<br/> | If ''Crash Detection'' is enabled, it monitors acceleration on each axis which helps detecting an accident.
