5. Information
1. Detectors
This displays the main information on the detector (type, range, detected gas).
2. Events
Figure 40: Example of gas alarm records
1. Alarm events
This displays, for each of the detectors concerned: detector ID, alarm type (Al1,
Al2, Al3, Al1mean, Al2mean, Al3mean, OVS), status (activated = ON or
deactivated = OFF) as well as the date and time of occurrence or of the release.
The letter “S” appears on the line if the events were obtained when the MX 32
was in simulation mode
Delete deletes all the data. Up to 512 events can be memorized. Beyond that,
the most recent event deletes the oldest.

2. Fault records
This displays, for each detector concerned: event type (UDS = Under-scale),
RANGE = measurement out of range, DEF =Failure, DOUBT = clear doubt),
status (activated = ON or deactivated = OFF) as well as the date and time of
appearance or release. This file cannot be deleted.
The measurement is lower or equal to the value of the UDS programmed.
Detector failure (out of range, line cut, defective cell, etc.).
Measurement out of range.
Concentaration higher than 100% of LEL.
