Man Down Alarm
The Man Down Alarm is a critical and potentially lifesaving safety feature of every
ToxiRAE Pro CO2. 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 ToxiRAE Pro CO2 not only goes into alarm locally on the
instrument, but also remotely, over the RAE Systems Dedicated 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.
Whenever the Man Down feature is on, the main screen displays a Man Down icon along the
top to indicate it is active:
When the Man Down feature is on and there is no gas alarm, the ToxiRAE Pro CO2 senses that
it is motionless for the amount of time set in the “Motionless Time” parameter. If the
instrument is not moved during that time, then a pre-alarm is activated to alert the user, and
shows the “Are You OK?” screen. Pressing [Y/+] clears the alarm and returns the ToxiRAE
Pro CO

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
•
Motionless Time (time the instrument is motionless before initiating a pre-alarm)
•
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)
