Intrusion Detection Systems
Cross-references point to the standards that now own the topic after the October electrical rewrites: MV cable to medium-voltage-cables, energy storage to battery-energy-storage-systems, service grounding to grounding-and-bonding, lightning to lightning-protection.
Showing changes from Rev 2
to Rev 3
in Intrusion Detection Systems.

## The intrusion control panel shall be powered from a dedicated 120V AC branch circuit and shall not share AC power with fire alarm or emergency power circuits without documented coordination.
−## Sharing intrusion AC power with a fire alarm panel or generator-backed circuit creates cross-system fault propagation and complicates code compliance; coordinate the dedicated branch circuit with the electrical engineer early. See [[sync/electrical-service-entrance]]. {note}
