The options below can be all active at the same time for each of the ROI.
- Range Temperature: in this option the alarm notification is triggered when the indicated value is reached
at the range (upper or lower alarm) during the indicated time. Both alarms, maximum and minimum, can
be set. The parameters for setting this alarm mode are:
o
Maximum temperature: maximum temperature value above which an alarm situation is
considered.
o
Minimum temperature: minimum temperature value below which an alarm situation is
considered.
- Rate of Rise: this option allows selecting a temperature value and a time in seconds. The notification
alarm is triggered if the relative value between maximum and minimum occurs in the indicated time.
o
Increase temperature: the relative temperature value between the maximum and minimum
temperature value.
o
Time: size of the time buffer in which the relative temperature difference is calculated.
•
Security temperature
: the setting of the security temperature is associated with the time delay. This
temperature difference corresponds to the negative variation from which the timer stops. For example,
for a temperature threshold of detection set at 70 ºC and a delay time of 10s, if the security temperature
is 5 ºC, then the detection delay will only be stopped until the measured temperature drops below 65 ºC.
On the other hand, if the measured temperature falls below 65 ºC before 10s, then no alarm condition
should be generated.
•
Delay
: it is possible to set a delay time to activate the alarm when the temperature value reaches the
indicated value. The delay can be selected between 5-30 seconds.
•
Latching mode
: you may latch or unlatch the alarms.
•
Pre-Alarm
: note that the Pre-Alarm can only be activated when an Alarm is set/active.
Once you’re done configuring the alarm or pre-alarm, it is necessary to save the changes in the
Settings
tab.
8.5.2 Alarms Pop-up Notification
Once an alarm is active, a pop-up appears on the screen indicating the name of the region in alarm, the
temperature that triggered the alarm and the active alarm time.
Figure 32: Alarms Pop-up Notification
The pop-up will keep displaying until the user accepts it, after which the alarm can be viewed in the
Notifications
window, as shown in the next page:
