Networked and Environmental Monitored POU
Alarms
Alarm Notifications
The POU supports three types of alarm notification:
E-Mail: The unit can be configured to send alarm e-mails to up to five recipients.
SNMP: The unit can be configured to send SNMP traps to up to two trap servers.
Buzzer: When a remote display is attached, the unit can turn on an audible alarm.
The unit is capable of any combination of the above alarms at once. Alarm type combinations are selected per alarm via the check boxes which are displayed for each alarm on the Alarms page.
Alarm Types
The POU provides three types of alarm messages via E-Mail and SNMP:
Trip: Occurs when a sensor value goes above a high trip threshold or below a low trip threshold.
Clear: Occurs when a sensor already in the Tripped or Unplugged state goes back into its normal range.
Unplugged: Occurs when a sensor with an alarm set loses contact with the main unit due to the sensor being physically unplugged or another communications error.
Alarms can be added for each internal device or external sensor displayed on the Alarms page. An alarm is added by pressing the “Add New Alarm Button” and selecting the sensor value to be monitored from a drop down menu.
Thresholds
The user must set a trip threshold and type for each alarm that is added to the Alarms page. The threshold type is chosen as either “High Trip” or “Low Trip” from a drop down menu when the alarm is created. The threshold value is typed into a data window when the alarm is created. Alarms are triggered based on the selected sensor’s data and the trip threshold type and value. Alarm settings can be edited or deleted at any time.
Analysis of each unit is recommended before setting alarm thresholds as some of the values monitored by the unit are relative values, whose scale will differ slightly between units. Allow each unit to operate under normal, steady state conditions for several hours before setting alarm thresholds. By allowing the
Version 1.0 31
Networked and Environmental Monitored POU sensors to operate for several hours, the user can better understand what the normal variations are; thereby allowing the user to choose alarm thresholds that will not trigger numerous false alarms.
Note: Changes in settings take a few moments to become active. Rapidly resetting alarm values may not provide the desired results. Allow up to 2 minutes after changing a setting before modifying it again.
