NFPA 110-2025 Standard for Emergency and Standby Power Systems 6.2.11-6.2.13: 6.2.11 to 6.2.13 Exercise timer, test switch and position indication

A programmable timer exercises the EPS as Chapter 8 requires (not needed in health care facilities testing to NFPA 99), and during exercise the load returns to primary power if the EPS fails; each ATS has a test means that simulates primary failure and transfers load; and two labelled pilot lights or another approved indicator show switch position.

What else in your programme already covers this

This control maps to 2 controls across 2 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.

  • 6.2.4.4-6.2.4.6 6.2.4.4 to 6.2.4.6 Manual operation, retransfer delay and test switch
  • 9.55-9.56 Run and stop signals, simulate-mains-failure switches and alarm monitoring

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.
