Emergency Alert System
An Emergency Alert System (EAS) receiver can control an Imagestore 750 through its serial port
and GPI connector, provided the EAS option is installed. See
Emergency Alert System (EAS) on
page 35 for more detail.
Monitoring and Alarms
Many different error conditions are being continually monitored by the Imagestore 750 system.
By assigning an appropriate alarm level to each error condition, you can determine whether a
system is running correctly based on your facility’s requirements.
Alarm Levels
Alarm levels are configured for each error condition either in the Imagestore 750 Configurator
(System Settings > Status Monitoring) or at the front panel (‘Config Alarms’). An alarm level
takes one of the following values:
No error Does not contribute to an alarm.
Minor error Contributes to an alarm as a minor error.
Major error Contributes to an alarm as a major error.
Critical error Contributes to an alarm as a critical error.
See System Settings on page 158.
The following table shows the different error conditions that are monitored by the Imagestore
750. The factory default alarm level for each error condition is shown by a check mark:
