      Notification Object

      Specifies the object to which alarm notifications will be sent. You can select the account contact or a topic.

      • The account contact is the tenant owner. If a user registers both a mobile number and an email address, they will receive alarm information through both channels. However, if only one of these contact methods is registered, the alarm information will be sent exclusively to that registered one.

      Trigger Condition

      Specifies the condition for triggering an alarm notification. You can select Generated alarm (when an alarm is generated), Cleared alarm (when an alarm is cleared), or both.
