30.34.35 Monitored perimeter security fence system.

“Monitored perimeter security fence system” means a perimeter alarm system with an assembly of battery-powered equipment, including but not limited to: a monitored alarm device and energizer which is intended to periodically deliver pulses to a security fence, a battery charging device used exclusively to charge the system’s battery, and other integrated components.

(a) The design, construction, and use of monitored perimeter security fence systems shall be allowed, subject to the following requirements:

(1) IEC Standard No. 60335-2-76. Unless otherwise specified herein, monitored perimeter security fence systems shall be constructed and operated in conformance with the specifications set forth in International Electrotechnical Commission (IEC) Standard No. 60335-2-76, current edition.

(2) Power Source. The energizer for monitored perimeter security fence systems must be driven by a commercial storage battery not to exceed twelve (12) volts DC. The storage battery is charged primarily by a solar panel. The solar panel may be augmented by a commercial trickle charger.

(3) Perimeter Barrier. Monitored perimeter security fence systems shall be installed behind a nonelectrified fence or wall that complies with section 30.34.30(b).

(4) Emergency Gate Access. Before a monitored perimeter security fence system is activated, a Knox device shall be approved by the fire department. The Knox device will be installed at the main entry gate and fully functional at all times when the monitored perimeter security fence system is operational.

(5) Setback. The perimeter security fence shall be set back six (6) inches to twelve (12) inches from the nonelectrified fence or wall in order to prevent inadvertent access to the battery-charged fence.

(6) Design/Height. The monitored perimeter security fence shall be visually transparent and comprised of twenty (20) twelve and one-half (12.5) gauge galvanized steel wires which are run horizontally to the height of ten (10) feet, or two (2) feet higher than the perimeter barrier fence (whichever is greater).

(7) Warning Signs. Monitored perimeter security fence systems shall be clearly identified with bilingual warning signs that read: “Warning – Electric Fence” at intervals of not less than thirty (30) feet.

(8) Location. Monitored perimeter security fence systems shall only be permitted on commercial and industrial zoned properties.

(b) Police Department Permit Requirements. All monitored perimeter security fence systems shall be permitted in accordance with Chapter 3B (Alarm Systems).

(c) It shall be unlawful for any person to install, maintain or operate a monitored perimeter security fence system in violation of this chapter or Chapter 3B (Alarm Systems).

(d) The monitored perimeter security fence system shall transmit a signal to an alarm monitoring business in response to an intrusion or burglary. The system shall not directly connect to or call law enforcement. The business must first verify the alarm event prior to requesting deployment of law enforcement. (Ord. No. 2021-02, § 2, 7-1-21)

(b) Electrified Fences. Electrified fences, other than those permitted by section 30.34.35, shall not be installed within the city.

(c) Wire Mesh Fences. Wire mesh fences shall not be installed within any required front yard, side yard or rear yard setback area whenever this is adjacent to a street in any residential or commercial zone. In the downtown specific plan districts, no wire mesh fencing will be installed within the front thirty (30) feet or the side or rear twenty (20) feet whenever adjacent to a street or an alley.
