IMPORTANT! BUMP TEST THE MONITOR
BEFORE EACH DAY’S USE
Prior to each day’s use, every gas detection monitor should be bump tested to confirm the
response of all sensors and activation of all alarms by exposing the monitor to a concentration of
target gas that exceeds the low alarm set point. A bump test is also recommended if the monitor
has been subjected to physical impact, liquid immersion, an Over Limit alarm event, or custody
changes, or anytime the monitor’s performance is in doubt.
To ensure greatest accuracy and safety, only bump test and calibrate in a fresh air environment.
The monitor should be calibrated every time it does not pass a bump test, but no less frequently
than every six months, depending on use and exposure to gas and contamination, and its
operational mode.
• Calibration intervals and bump test procedures may vary due to national legislation.
• Honeywell recommends using calibration gas cylinders containing the gas that is
appropriate to the sensor you are using, and in the correct concentration.

any alarms are enabled but not functional, the instrument should not be used.
7.4. Glance Mode
Glance Mode allows you to get vital information without turning the MicroRAE on. You can check
information such as the instrument’s model number, installed sensor types, etc., which may help
when taking inventory of instruments and their sensors or when working with service or support
personnel. Glance Mode can be enabled/disabled via ProRAE Studio II.
7.4.1 Enter Glance Mode
Note: The instrument must be configured so that Glance Mode is turned on (the default mode is
“On”). This can be done in ProRAE Studio II.
With the MicroRAE turned off, press and hold [Y/+] to enter Glance Mode. The feature is latched,
meaning that it runs even after you release the [Y/+] key. If you see the message “GLANCE
DISABLED,” you must configure the instrument to use Glance Mode.
If Glance Mode is enabled, the first screen is displayed. After releasing [Y/+], other screens
release, other screens can be displayed by pressing the [Y/+] Key. In ProRAE Studio II, Glance
Mode can be enabled or disabled by checking or unchecking the box labeled “Enable Glance
Mode.”
23MicroRAE User’s Guide
7.4.2 Screens
Every screen displayed in sequence as configuration. Press [Y/+] to advance to the next screen.
Press [MODE] to exit Glance Mode and turn the instrument off. The screens are shown in
sequence.
7.4.3 Exit Glance Mode
MicroRAE exits Glance Mode and turns off when you press the [MODE] key. In addition, if you
do not press either key in 60 seconds, the MicroRAE automatically exits Glance Mode.
7.5. Comfort Beep
A Comfort Beep is a single beep of the audible alarm at 60-second intervals that provides a
reminder that the MicroRAE that it is functioning. It can be turned on or off.
7.6. Man Down Alarm
The Man Down Alarm is a critical and potentially lifesaving safety feature of every MicroRAE. The
Man Down Alarm is based on the premise that if the instrument is motionless when it is not
supposed to be, something wrong may be happening to its user. If that is the case, the MicroRAE
not only goes into alarm locally on the instrument, but also remotely, over a wireless network, to
notify people in the vicinity, as well as remote safety officers at a command center, that a person
is down, so that help can be dispatched quickly.
Note: Remote notification requires wireless connection to a network.
Whenever the Man Down feature is on, the main screen displays a Man Down icon along the top
to indicate it is active:
IMPORTANT!
When gas alarm conditions exist at the same time as the Man Down alarm is activated, the pre-alarm
stage is skipped, and the instrument goes straight into Super Alarm (gas and Man Down) with four
beeps/flashes per second.
When the Man Down feature is on and there is no gas alarm, the MicroRAE senses that it is
motionless for the amount of time set in the “Motionless Time” parameter via ProRAE Studio II. If the
instrument is not moved during that time, then a pre-alarm is activated to alert the user, and shows the “OK?”
screen. Pressing [Y/+] clears the alarm and returns the MicroRAE to its normal operation. Pressing [MODE]
sets it into Man Down Alarm (and if wireless connectivity is enabled, a Man Down message is sent in real time
to remote observers). If neither key is pressed, then after the countdown, it goes into Man Down Alarm (again
sending a message to remote observers if wirelessly enabled).
Settings for Man Down are available in ProRAE Studio II for:
• Off/On
• Motion Sensitivity (set to low, medium, high, or custom percentage)
• Falldown Sensitivity (set to low, medium, or high to compensate for ambient vibration or motion)
• Window (time the instrument is motionless before initiating a pre-alarm, in seconds)
• Warning Time (countdown, in seconds, from pre-alarm to Man Down alarm)
• Falldown Window (time after falling down is sensed, in seconds); Whenever the acceleration
speed is greater than the Falldown Sensitivity, the Man Down feature is invoked.
24MicroRAE User’s Guide
When the Man Down alarm is activated, the buzzer sounds and LEDs flash continuously, and a countdown
begins.
• If the MicroRAE’s user presses [Y/+] for “Yes” in response to the “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 “OK?” question on the screen
before the countdown reaches zero, the Man Down alarm is sounded and LEDs flash
continuously.
• If the person presses [MODE] during the countdown, answering the “OK?” question by pressing
[MODE] for “No,” the Man Down alarm starts.
If wireless connectivity is enabled, and the MicroRAE is connected to a network, a Man Down message is
also sent to remote observers.
IMPORTANT!
When using the Travel Charger or Truck Mount to charge a MicroRAE, the Man Down alarm is
automatically disabled so that the instrument does not go into Man Down alarm because of inactivity. This
requires no changes to the instrument’s settings.
Please note that Travel Chargers with a serial number lower than M0320001U5 and Truck Mounts with
serial numbers lower than M035000170 do not support this feature. It is also recommended that older
MicroRAE instruments have their firmware upgraded to version 1.10 or higher.
7.6.1 Parameter Settings And Sequence Of Events
When a fall is sensed, as determined by the Motion Sensitivity and Falldown Sensitivity settings,
the Falldown Window starts. If motion resumes, then the instrument resets itself and is ready for
the next fall or motionless period.
7.6.1.1. Parameters Configured By ProRAE Studio II
Index Parameter Default Value Range
1 Window time 30 seconds 30 to 90 seconds
2 Warning time 30 seconds 30 to 180 seconds
3 Falldown Window time 180 seconds 0* to approximately 1,000 seconds
4 Motion Sensitivity Medium Low (7%)
Medium (37%),
High (63%),
Custom
5 Fall Sensitivity Medium Low (33%),
Medium (67%),
High (100%),
Custom
* If the Falldown Window value is set to “0,” the Man Down algorithm focuses only on motionless
behavior. If the Falldown Window 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.
• If the MicroRAE’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.
25MicroRAE User’s Guide
• 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.
• If the person presses [MODE] for “No” during the countdown, the Man Down alarm starts.
If wireless connectivity is enabled, and the MicroRAE is connected to a network, a Man Down message is
also sent to remote observers.
7.6.1.2. Turn Man Down On Or Off
Turn on the Man Down feature, or turn it off, using ProRAE Studio II.
7.6.1.3. Set The Sensitivity
Individual sensitivity settings for Motion (acceleration) and Falldown allow for customization to
individuals or activities. Default values are set at the factory, but it can be helpful to try other
settings in order to customize an instrument’s response.
7.6.1.4. Set The Times
Once a trigger occurs, there is a time before a warning is displayed and when the Man Down
alarm is initiated.
7.6.1.5. Upload Settings To The MicroRAE
When any changes to Man Down (or any other) settings are made in ProRAE Studio II, you must
upload them to the instrument in order for them to be used. Click the “Upload all settings” button.
