MS HB823

Defines "battery-charged security fence" as an alarm system with a battery-operated energizer that delivers voltage impulses to a fence, requiring it to interface with monitored alarm devices and meet International Electrotechnical Commission Standard 60335-2-76.

Battery-charged security fences must be located on non-residential property, powered by a commercial storage battery not exceeding 12 volts DC, surrounded by a non-electric perimeter fence at least 5 feet high, and marked with warning signs reading "WARNING—ELECTRIC FENCE" at intervals of no more than 30 feet.

Prohibits municipalities and counties from requiring permits or fees for battery-charged security fence installation beyond existing alarm system permits, or from imposing operational requirements inconsistent with state standards.

Voids all existing municipal and county ordinances requiring certification or licensure for battery-charged security fence contracting, closed-circuit video system contracting, or electronic access control system contracting.
