If the appliance is equipped with the "Roundsman" function (which is optional), a list of names can be preprogrammed
using the COM 2100 software and it can be consulted manually via the keypad.

validate another name, as follows:
- Current location / name,
- Enter,
- Scrolling through preprogrammed list downwards or upwards with keys:

7.1 "Gas" alarms
Depending on the programming used and the type of gas, the "gas alarms" can be triggered on exceeding a preset value:
•
2 instantaneous thresholds per channel for Explo, Tox or Oxygen,
•
High and low thresholds on Oxygen channel (2 low thresholds on option),
•
1 instantaneous threshold on the katharometric channel,
•
Exposure limit (STEL) corresponding to a sliding average over 15 minutes (depending on the country) for
each channel equipped with a toxic gas cell,
•
Mean exposure (TWA) corresponding to a sliding average over eight hours for each channel equipped with
a toxic gas cell.
In this way, as soon as the predefined alarm thresholds are exceeded on at least one channel, the MX 2100 triggers an
audio and light signal. The alarm message or messages (FAULT, ALARM, TWA, STEL, min., etc.) and the
measurement value in the corresponding field appear on the display unit.
