TRANSCRIPT
The Integrated Alarm System for the Alma Observatory
A.Caproni, E.SchmidOrganisation for Astronomical Research in the
Southern Hemisphere (ESO)
ICALEPCS 2017, Barcelona
Motivation
• Current alarm system is not enough– Operator panels
– Misses alarms from external systems
• ALMA facility is not only the ARRAY
• Have the facility under control 24/7
• Increase operators and engineers awareness
• Reduce the failure-to-reaction time
• Improve telescope efficiency
