9 Warning Report Settings
To enable warning reports to be sent when loggers go into an alarm
condition set Warning Monitoring to On. Warnings can be sent to up
to four recipients. These can be either Emails or SMS messages to
cell phones. To send a warning message as an SMS simply enter the
mobile phone number in the Recipient field. Note that warnings will
only be sent for loggers that have had Warning Monitoring set to On
during remote unit registration. When the alarm condition has ceased
to exist a Recovery message will be sent.
Note: The RTR-500GSM is triggered by transitions from normal to
alarm condition, and visa versa. When testing this function before
deploying it is important to understand that a warning will not be sent
if the logger is already in an alarm condition when the unit is first
placed into Run. In order for an alarm to be sent the logger must be
first in a normal condition and then move into alarm.
