The system is designed to be in one of the following operative states:
NORMAL, ALARM, FAULT, TEST/MAINTENANCE, UNSET, EMERGENCY
NORMAL
It is the normal system operative state without alarms and faults. The screen in this state
displays the channels (gas detectors) with measured gas concentration.
Figure 20) Typical NORMAL state screen.
ALARM
The Alarm condition is activated when one or more gas detectors measure a gas concentra-
tion higher than the alarm threshold set during the control panel configuration (refer to the
separate cofiguration software manual for more details).
The programming of the alarm thresholds and the other parameters of each channel can be
freely set during the configuration phase from a PC.
The display indication will switch to the Alarm screen:

When more than one input channel enters in alarm state simultaneously, alarms are di-
splayed according to the following rules:
³
The events are ordered by severity, as follows: Over-range, Alarm 3, Alarm 2, Alarm 1;
³
Over-range is seen as an Alarm event with the highest severity.
