A Comfort Beep is a single beep of the audible alarm at 60-second intervals that reminds the

person using the QRAE 3 that it is functioning. It can be turned on or off.

8.3.3.9. Man Down Alarm

The Man Down Alarm is a critical and potentially lifesaving safety feature of every QRAE 3. 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 QRAE 3

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.

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:
