Alarm
The Alarm condition is activated when one or more gas detectors
measure a gas concentration higher than the alarm threshold set dur-
ing 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.
When more than one input channel enters in alarm state simultaneously, alarms
are displayed according to the following rules:
-
The events are ordered by severity, as follows: Over-range, Alarm 3,
Alarm 2, Alarm 1;
-
Over-range is seen as an Alarm event with the highest severity.
-
In case there are present also other events than alarms, like faults, the
alarm events will be in the upper side and the others in the bottom side
of the display.
At any access level, by selecting in the main window the 1—Menu and than AC-
TIVE EVENTS sub menu, it is possible to see the gas detectors in alarm state, or
not yet reset.
