1. The Man Down Alarm is a critical and potentially lifesaving safety. The Man Down Alarm is based on the premise that if the instrument is motionless when it is not supposed to be, something is wrong or may be happening to its user. The monitor not only goes into alarm locally on the instrument, to notify the people in the vicinity, but also remotely, over Wireless Network,  as well as remote safety officers at a command center, that a person is down, so that help can be dispatched quickly.
2. When the Man Down feature is on and there is no gas alarm, the Equipments senses that it is motionless for the amount of time set in the "Motionless Time" parameter. If the instrument has not moved during that time, then a pre-alarm is activated to alert the user, and shows the "Are You OK?" on the screen. Pressing [Y/+] clears the alarm and returns the Equipments monitor 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 via software. If neither key is pressed, after the countdown, it goes into Man Down Alarm again sending a message to remote observers (if wireless enabled).
