Single-conversion UPS typically gives up to about 15 minutes for safe shutdown or bridging to the generator. Double-conversion UPS serving Medical IT and other grade A or B outlets needs 3 hours' autonomy where changeover of 0.5 s or less is required (typically Group 2), reducible to 1 hour if a secondary supply is available within 15 s; in theatres autonomy should allow patient closure of all cases, and a warning when on battery should be considered so new procedures are not started. Designers should agree autonomy with stakeholders and clinical staff through the Group.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
