Click the Edit button and select the alarm type. Options include:
- For any iSIC type: Changing the sample and log interval
- For a 3100-iSIC AT&T/Cingular Raven XT 2G modem: Sending an SMS message or SMTP email
When finished setting up the alarm, click Update iSIC to send the configuration to the data logger.
Note: iSIC alarm conditions are evaluated each sample interval. For example, if a data logger is set to sample every 60 minutes under normal conditions, and a Change log interval alarm is selected, it will check the alarm condition every 60 minutes to determine if it should switch to the different interval.
