AL HB120

Defines "battery-charged fence" as an alarm system component with a fence and battery-powered energizer that produces electric pulses upon contact and meets specific technical and safety requirements.

Requires battery-charged fences to be no more than 12 volts direct current, at least 10 feet tall, surrounded by a nonelectric perimeter fence at least 5 feet high, and marked with warning signs at 30-foot intervals.

Prohibits municipalities and counties from requiring additional permits or fees beyond standard alarm system permits, imposing inconsistent installation or operational requirements, or banning battery-charged fences entirely.

Exempts agricultural and animal containment fences from the bill's provisions, while allowing municipalities to charge standard business license fees for installation services.

Becomes effective immediately upon passage and gubernatorial approval.
