Chapter 5: Energy sources, converters, inverters and accessories – NFPA 111-2025 Standard on Stored Electrical Energy Emergency and Standby Power Systems
NFPA 111-2025 Standard on Stored Electrical Energy Emergency and Standby Power Systems 5.3.1-5.3.2: 5.3.1 and 5.3.2 Instruments and visual indicators
The SEPSS must show, locally and with remote capability, battery voltage and output voltage, current and (for ac) frequency on each leg, at both Levels. Individual visual indicators with a common audible alarm show load on normal power, load on emergency power, output overload, high temperature, ECE in bypass, low battery, major and minor alarms, and at Level 1 an open output breaker.
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.
