Sizing note
NFPA 72 requires 24 hours of standby power followed by 5 minutes of alarm. The 40 Ah rating suits larger panels and systems with multiple NAC circuits. Verify your panel's standby current draw against this capacity before specifying. Kidde offers the full range from 4 Ah to 55 Ah to match every system size.
