Note: For information on overriding default configuration settings, refer to Modify configuration settings.

Follow this procedure to integrate user configurable alarm limits with the default HiLo category alarms (LOW-LOW, LOW,HIGH, and HIGH-HIGH). The integration applies to alarms associated with analog, rate, and flowTotalConfig records. Once integrated, user configurable alarm limits also become the valid alarm suppression states "uhi" and "ulo".

To integrate user alarm limits with default alarms

  1. In the %DNADataRoot%\RealTime\config\Settings directory, either create or open the RealTime_HiLoIntegratedUserAlarms.json file.

  2. In the following line, change the value from false to true.

    {

    "RealTime": {

    "HILO_INTEGRATED_USER_ALARMS": true

    }

    }

  3. Save the file.

  4. Restart the RealTime service.
