Acknowledge alarms that require authentication

Some industries require that an explicit "signature" or user authentication be performed when acknowledging certain types of alarms. InTouch takes advantage of the Alarm Client control or script functionality to perform this type of authentication operation. The alarm priority is the key factor used to determine if the alarm or alarms to be acknowledged require a specific user signature.

You can configure alarms to require authentication so that users can acknowledge them. Alarms configured with authentication required means that the run time user must enter his or her credentials in order to acknowledge the alarm or group of alarms. If the system is configured with a smart card reader, the user can enter smart card credentials.

This section describes how to acknowledge alarms in WindowViewer that require authentication.
