* If the Falldown Time value is set to “0,” the Man Down algorithm focuses only on motionless
behavior. If the Falldown Time value is not set to zero, the algorithm uses acceleration to trigger
its function.
If acceleration is sensed, and motion does not resume, then the Warning Time starts. During
this period, the instrument waits for motion. If no motion occurs by the end of the Warning
Time, the Window period is entered. During that time, the display shows the “Are You OK?”
message. The buzzer sounds and LEDs flash continuously, and a countdown begins.
l
If the MultiRAE’s user presses [Y/+] for “Yes” in response to the “Are You OK?” question
on the screen before the countdown reaches zero, the Man Down alarm stops and the
main reading screen is displayed.
l
If the person does not press [Y/+] for “Yes” in response to the “Are You OK?” question on
the screen before the countdown reaches zero, the Man Down alarm is sounded and
LEDs flash continuously.
l
If the person presses [MODE] for “No” during the countdown, the Man Down alarm
starts.
