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. The design, construction, and use of monitored perimeter security fence systems may be permitted subject to the approval of a conditional use permit pursuant to Chapter 18.114, subject to the following additional 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 18.34.060 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. Separation. The perimeter security fence shall be set back four (4) inches to twelve (12) inches from the nonelectrified fence or wall in order to prevent inadvertent access to the monitored perimeter security fence. 6. Design/Height. The monitored perimeter security fence shall be visually transparent and comprised of twelve and one-half (12.5) gauge galvanized steel wires which are run horizontally, up to the maximum height of ten (10) feet. 7. Warning Signs. Monitored perimeter security fence systems shall be clearly identified with bilingual warning signs in compliance with Civil Code § 835(b)(3) that read: “Warning – Electric Fence” at intervals of not more than thirty (30) feet. 8. Location. Monitored perimeter security fence systems shall only be permitted on properties zoned LI Light Industrial and HI Heavy Industrial. 9. Alarm Signal. 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.” -This page intentionally left blank-
