At a minimum, the warning signs shall meet all of the following criteria:(A) The warning signs are placed at each gate and access point, and at intervals along the fence not exceeding 30 feet.(B) The warning signs are adjacent to any other signs relating to chemical, radiological, or biological hazards.(C) The warning signs are marked with a written warning or a commonly recognized symbol for shock, a written warning or a commonly recognized symbol to warn people with pacemakers, and a written warning or commonly recognized symbol about the danger of touching the fence in wet conditions.(4) The height of the fence does not exceed 10 feet or 2 feet higher than an existing perimeter fence, whichever is greater. The electrified security fence shall be located behind a perimeter fence that is not less than 5 feet in height.(c) The electrified security fence may interface with a monitored alarm device in a manner that enables the alarm system to transmit a signal intended to summon the business, a monitoring service, or both the business and a monitoring service, in response to an intrusion or burglary.(d) (1) An owner of real property shall not install or operate an electrified security fence where a local ordinance prohibits the installation or operation of an electrified security fence. A local ordinance that prohibits or regulates only the installation or operation of an electrified fence as defined in Section 17151 of the Food and Agricultural Code does not apply to an electrified security fence.(2) If a local ordinance allows the installation and operation of an electrified security fence, the installation and operation of the fence shall meet the requirements of that ordinance and the requirements of subdivision (b).(Amended by Stats. 2021, Ch. 148, Sec. 1.
