Context: Alarm shelving of apparent nuisance alarms helps focus on high priority alarms, optimizing operators’ time and promoting a safer, more secure facility.

Ref.
Alarm shelving is a facility for manually removing an alarm from the main list and placing it on a shelve list, temporarily preventing the alarm from re-occurring on the main list until it is removed form the shelf. Shelving will normally be controlled by the operator, and is intended as a "last resort" for handling irrelevant nuisance alarms that have not been caught by signal filtering or alarm suppression mechanisms.
