K Reports
K reports are based on Sensor state and gas concentration.
Alarm Type Definition
Alarm (A or a)
Gas concentration is above the alarm set point. The alarm set point
is commonly configured in the sentry using the font panel. Note that
the LANServer reports an alarm if the sentry reports the alarm – the
LANServer does not report an alarm by comparing the gas level to
the set point. When reported on the event screen – the letter ‘A’
indicates a new alarm and the letter ‘a’ indicates the alarm is still
active but this is not a new event.
Warning (W or w)
Gas concentration is above the warning set point. T he warning set
point is commonly configured in the sentry using the font panel. Note
that the LANServer reports an warning if the sentry reports the
warning – the LANServer does not report a warning by comparing
the gas level to the set point. When reported on the event screen –
the letter ‘W’ indicates a new warning and the letter ‘W’ indicates the
warning is still active but this is not a new warning.
Comms ( C )
This event is generated by the LANServer if a Sensor reports that
the analog value is bad or if it loses communications with the Sentry.
When reported on the event screen – the letter ‘C’ indicates a new
comms event is active.
Threshold ( T )
The web project builder configured, for each Sentry-Sensor, a user
threshold, which if the gas level rises above it, generated a threshold
event. The evaluation of this event is perf ormed by the LANServer;
the Sentry does not report this event directly. When reported on the
event screen – the letter ‘W’ indicates a Threshold Event is active.
Delta ( D )
The web project builder configured, f or each sentry-sensor, an event
delta value. If the gas level changes by more than this delta value
then a delta event is generated. The gas level must be above the
threshold level before delta events are evaluated. The evaluation of
this event is performed by the LANServer; the Sentry does not report
this event directly. When reported on the event screen – the letter ‘D’
indicates Delta Event has just occurred.
Normal ( N )
The LANServer reports a normal event when the state of sensor
returns to normal – no alarms, no warnings, analog value is valid, no
user threshold event and no delta event. The evaluation of this event
is performed by the LANServer; the Sentry does not report this event
directly. When reported on the event screen – the letter ‘N’ indicates
that the Sensor is in a normal condition.
