Configuring GSM Message Settings

After configuring the Hardware and Data tab of an SMS/text node, you can configure the alarm filter and notification message preferences on the Message Settings tab.

Setting up alarm filters allows you to limit alarm messages that trigger outgoing SMS. You can base the filter on specific alarm criteria, such as high-severity alarms or specific alarm areas.

The result of an alarm filter is used as a true/false value. The expression is checked against the alarm message. A non-zero return allows the alarm through the filter.

You can define the subject, the body, and the recipient of the alarm message to be sent. Optionally, you can create templates of subject and message combinations to reuse for other configurations. Learn more

  1. In the SMS/text node configuration dialog, switch to the Message Settings tab.
