Trigger Settings
 Analog / digital selection - determines which set of trigger settings apply to the alarm.
Analog selection is disabled if the meter tag is a power monitor alarm flag.
 High / low threshold - set the upper and lower bounds of the alarm range. Either the
high threshold, the low threshold, or both can be selected depending on the nature of
the alarm. If only the high threshold is specified, the alarm triggers if the meter tag
value exceeds the threshold. If only the low threshold is specified, the alarm triggers if
the value is less than the threshold. The range selections are disabled unless both
thresholds are specified.
 Range: Alarm on inside - triggers the alarm when the value of the meter tag exceeds
the low threshold AND is less than the high threshold.
 Range: Alarm on outside - triggers the alarm when the value of the meter tag exceeds
the high threshold OR is less than the low threshold.
 Digital tag trigger settings - triggers the alarm when the selected condition occurs.
Communication Alarms
A communication alarm is triggered when a device fails to respond to four consecutive
polls. To enable a communication alarm, select the Enable comm. loss alarm checkbox on
the Device Setup screen.
An email will be sent to alarm subscribers when communication loss with a device is
detected and another sent when communication with the device is restored. The device
must be successfully communicating after the logger service starts before the loss email
can be triggered. This will prevent nuisance emails when the logger service starts. These
communication alarms will not be shown on the Alarm Status or the Alarm Log web
pages.
Set up Email Alarm Subscriptions
Each user can configure one or more alarm subscriptions. Each alarm subscription can be
assigned to an individual domain or to 'none' which is a global subscription to all domains.
A subscription consists of up to three email addresses along with a schedule that
determines when each email address is active.
1. Navigate to the My user settings link in the System tab.
2. Click the Enable alarm notifications checkbox.
3. Click the Add a new alarm subscription link at the bottom of the screen.
No alarm is activated if the meter tag value is EQUAL to either
threshold.
