Settings are available for:

Off/On (off by default)

Motionless Time: time the instrument is motionless before initiating a pre-alarm (30 seconds by
default)

Motion Sensitivity: set to low, medium, or high to compensate for ambient vibration or motion
(medium by default)

Warning Time: countdown, in seconds, from pre-alarm to Man Down alarm (30 seconds by default)
When the Man Down pre-alarm is activated, the buzzer sounds and LEDs flash twice per second, and a countdown
begins.

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.

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 triggered.

If the person presses [N/-] during the countdown, answering the “Are You OK?” question with “No,”
the Man Down alarm starts.
If wireless connectivity is enabled, a Man Down message is also sent to remote observers.
IMPORTANT!
When gas or radiation alarm conditions exist at the same time as the Man Down is activated, the pre-
alarm stage is skipped and the instrument goes straight into a Super Alarm (gas or radiation and Man
Down) with four beeps/flashes per second.
8.3.5 Datalog
The instrument displays a floppy disk icon to indicate that a datalog is being recorded. The instrument
stores the measured gas concentration for each sensor, date and time for each measurement, Site ID, User
ID, and other parameters. The MultiRAE memory is sufficient to record six months’ worth of data for
five sensors at one-minute intervals, 24/7. All data are retained (even after the unit is turned off) in non-
volatile memory so that they can be downloaded at a later time to a PC.
8.3.5.1 Clear Datalog
This operation erases all data stored in the datalog. Select “Clear Datalog,” and then “Yes.”
Note: Once the datalog is cleared, the data cannot be recovered.
