Recorded Announcement Alarms

The Matrix Controller card maintains information from the Recorded Announcement Download Initiate message (0x0052) on all downloaded announcements in the CSP. Each DSP card maintains information on the announcements that it contains. When an announcement is downloaded, both cards verify that the information is correct and that it does not conflict with other announcements downloaded previously. For example, the cards verify that the same Announcement ID is not used for different announcements.

For alarms that indicate recorded announcement conflicts, the host must respond to quickly to ensure that the intended announcements are being stored and played-out.

See the Alarm message (0x00B9) in the API Reference for detailed information.
