JVA Z14 One Zone Security Energizer 4 Joule with LCD Display

The JVA Z14 One Zone Security Energizer is a high-performance electric fence energizer designed for residential, commercial, and industrial security applications. With a powerful 4–5 joule output and intelligent monitoring capabilities, the Z14 ensures perimeter integrity by continuously scanning the fence for voltage drops caused by tampering, poor maintenance, or environmental interference. Its integrated LCD display offers real-time feedback, including output and return voltages, battery status, and programmable settings. Built for reliability, the Z14 also features backup battery support, dynamic voltage monitoring, and advanced alarm triggers, making it ideal for high-risk or multi-zone installations.

Product Features

Intelligent High-Voltage Fence Monitoring

Delivers a short, safe high-voltage pulse every second and continuously monitors the return voltage to detect tampering or faults on the fence.

LCD Display with Voltage Diagnostics

Displays real-time fence status, including output voltage, return voltage, and battery level, with easy-to-navigate settings.

Single-Zone Security Management

Ideal for dedicated single-zone perimeter systems, offering full control and alarm triggering when live or earth wires are compromised.

Dynamic Voltage Monitoring

Reduces nuisance alarms by minimizing arcing while maximizing pulse effectiveness and power efficiency.

Gate Monitoring Input

Enables alert notifications if the security gate is opened or tampered with.

Earth Wire Monitoring

Triggers an alarm when the earth wire system is interfered with or shorted, enhancing fence protection.

Built-in Lightning and Surge Protection

Designed with internal protection circuitry to guard against lightning strikes and electrical surges, improving reliability in exposed locations.

Internal Battery Backup

Maintains full operation for up to 24 hours during power outages, with automatic switch-over to the internal backup battery.

Programmable Relays

Equipped with two programmable relays for alarm or automation integration; expandable to five on request.

Keypad Compatible

Supports the JVA Z-Range Keypad system (sold separately), allowing remote configuration, control, and fence monitoring.

Multi-Zone Integration

Can be networked with other JVA Z-Series energizers (up to 14 units per keypad) and supports pulse synchronization to avoid interference across zones.

Bi-Polar Operation Available (Optional)

Allows for bi-polar fence configuration upon request, improving performance in areas with poor soil conductivity.

Secure Key Switch Operation

Includes secure physical key switch for authorized activation and deactivation.

Diagnostic Mode

Advanced diagnostics help technicians and installers quickly identify faults or inefficiencies in the fence system.
