AL SB169

Defines "battery-charged fence" as an alarm system component consisting of a fence and energizer powered by a commercial storage battery (not exceeding 12 volts) that produces electric pulses upon contact and meets eight specific technical and safety requirements.

Requires battery-charged fences to interface with monitored alarm devices, be located on non-residential property, have an energizer meeting International Electrotechnical Commission standards, and be surrounded by a non-electric perimeter fence at least 5 feet high.

Mandates battery-charged fences be at least 10 feet in height (2 feet higher than perimeter fence) and marked with warning signs reading "WARNING-ELECTRIC FENCE" at intervals of not more than 40 feet.

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 that meet these specifications.

Becomes effective on the first day of the third month following passage and gubernatorial approval.
