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 are available for:
•
Off/On
•
Window (time the instrument is motionless before initiating a pre-alarm, in seconds)
•
Sensitivity (set to low, medium, or high to compensate for ambient vibration or motion)
•
Warning Time (countdown, in seconds, from pre-alarm to Man Down alarm)
