Alarm Acknowledgment Properties

This dialog box allows you to configure the alarm acknowledgment options.

General​

This tab defines the options for automatic alarm acknowledgment.

Acknowledgment on alarm reset​

When this option is selected (choice Yes), the alarm will be automatically acknowledged when the alarm condition disappears (return to normal state).

If the "Default" check box is selected, the displayed option is the one that have been in the general alarm options.

Acknowledgment on reset before delayed call​

When this option is selected (choice Yes), the alarm will be automatically acknowledged if the alarm returns to the normal state before the delayed call is triggered.

This option can be used to force the explicit manual acknowledgment of an alarm if this alarm lasts more than a defined time (call delay). It is particularly useful for dealing with alarms that require intervention if they last longer than a certain time (open door of a cold room for example).

If the "Default" check box is selected, the displayed option is the one that have been in the general alarm options.

Acknowledgment on group warned​

When this option is selected (choice Yes), the alarm will be automatically acknowledged when the first or all the associated call group (depending on next option) have been successfully warned.

If the "Default" check box is selected, the displayed option is the one that have been in the general alarm options.

Acknowledgment on first group warned​

When this option is selected (choice Yes), the alarm will be automatically acknowledged when one of the associated call group has been successfully warned.

If the "Default" check box is selected, the displayed option is the one that have been in the general alarm options.

Advanced​

This tab defines the advanced acknowledgment options for the alarm.

Alarm item​

This field displays the reference of the alarm item in the data source (monitored application variable that contains the alarm information).

Acknowledgment condition​

  • Acknowledgment item: This field defines the item of the monitored application that will contain the acknowledgment information to read. Enter the name of this item in the field or click on the button to the right of the edit field to search and select this item in the data source. If this field is empty, the item will be the same as the alarm item defined above.

  • Condition: The acknowledgment condition defines the state in which the item value is considered as an alarm acknowledgment indication.

Depending on the complexity of the condition to be expressed, select the type:

  • Simple: The condition is defined by an operator selected from the drop-down list and a reference value entered in the adjacent field. See Coding an acknowledgment condition.

  • Expression: The condition is defined by an alphanumeric expression. This expression can be entered in the edit field or generated from the expression editor by clicking the button to the right of the edit field (see Edition of an expression).

Acknowledgment report​

The option "Send acknowledgments to the server" allows, when validated, to transmit the acknowledgments made from ALERT to the monitored application.

This transmission is carried out by writing the "Value to be written" in the "Item to write".

  • Item to write: This field defines the item of the monitored application to be written to acknowledge the alarm. Enter the name of this item in the field or click on the button to the right of the edit field to search and select this item in the data source. If this field is empty, the item to be written will be the same as the acknowledgment item defined above.

  • Value to be written: This field defines the value that will be passed to the monitored application to acknowledge the alarm. This value can be a numeric value or a string. It can be entered in the field or generated from the expression editor by clicking on the button to the right of the edit field.
