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
