JVA Z28 Two Zone Security Energizer 8 Joule with LCD Display

The JVA Z28 Two Zone Security Energizer is a powerful and intelligent electric fence energizer designed for high-security applications across industrial, commercial, and estate-grade installations. Offering 8 joules of total output energy (4 joules per zone), the Z28 allows for complete dual-zone perimeter control with independent monitoring and alarm capabilities. Its LCD screen displays real-time voltage data for each zone, ensuring easy diagnostics and accurate fault identification. Built with robust lightning protection, battery backup, and optional solar integration, the Z28 is an ideal solution for security professionals seeking reliable and scalable electric fencing systems.

Product Features

Dual-Zone High-Voltage Monitoring

Each zone operates independently, enabling individual arming, disarming, and voltage control. A short or tamper in one zone does not affect the other, offering uninterrupted security.

LCD Voltage Display per Zone

An integrated backlit LCD screen provides real-time output and return voltage readings for both zones, along with battery health and programming settings.

Earth Wire Monitoring

Triggers an alarm if tampering with the earth wires is detected, providing added defense against intrusion attempts.

Gate Monitor Input

Monitors access points such as security gates, immediately triggering alerts if a gate is opened or compromised.

Dynamic Voltage Monitoring

Minimizes false alarms caused by arcing and environmental interference, while maximizing energy efficiency and extending battery life.

Built-in Lightning and Surge Protection

Designed with robust protection circuitry to safeguard the energizer against electrical surges and lightning strikes.

Internal Battery Backup

In the event of a power failure, the Z28 continues to operate for up to 18 hours using its built-in battery, ensuring 24/7 perimeter security.

High and Low Power Modes

Adjustable output settings allow the system to run at lower voltage during the day and full power at night, optimizing energy use and safety.

Secure Key Switch Operation

Prevents unauthorized access or tampering by requiring a physical key to activate or deactivate the energizer.

Diagnostic Mode

Enables advanced troubleshooting for installers and technicians, simplifying fence system maintenance.

Programmable Relays

Includes three standard relays (1 siren, 2 strobe), with the option to expand to six total relays via an additional relay board—ideal for alarm systems and automation.

Keypad Compatibility

Fully programmable when connected to the JVA Z-Range Keypad (sold separately), allowing full remote control of each zone’s power, settings, and alerts.

Pulse Synchronization

Synchronizes pulses with other Z-Range energizers when deployed as part of a multi-zone network to prevent interference and increase overall system reliability.

Solar Ready

Can operate using an 80-watt solar panel (via charge controller), making it a viable option for remote locations without grid power.
