JVA Z Range



JVA Z Range Energizers

The JVA Z11 and Z13 One‐Zone Security Energizers are the entry level energizers in the Z‐Range.

They are manufactured to meet customer demand for a simple, no-frills, economical unit for small, domestic, commercial and industrial sites. The units are fully compatible with the Z‐Range keypad and when wired up to a keypad are fully programmable.

The JVA Z-Range of One‐Zone Security Energizers with LCD displays are top‐of‐the‐range energizers meeting all requirements from the basic home security fence to fully integrated high profile installations. These energizers have LCD displays showing out and return voltages, battery condition and fence programming settings. The units are fully compatible with the Z‐Range keypad and when wired up to a keypad are fully programmable. The energizers can be networked with other Z‐Range energizers to synchronize pulses and become a multi‐zone group for larger sites where many zones are required. These energizers can be controlled by a PC or up to 3 keypads, or 1 keypad up to 14 Z‐Range energizers.

he JVA Z28 Two‐Zone Security Energizer with LCD display is a top‐of‐the‐range high power energizer ideal for installations where better zone identification is required. The Z28 can meet all requirements from longer wall‐top fences to industrial and high profile installations. The energizer has an LCD display showing return voltages for each zone, battery condition and fence programming settings. The unit is fully compatible with the optional Z‐Range keypad and when wired up to a keypad is fully programmable. The energizer can be linked with other Z‐Range energizers to synchronize pulses and become a multi‐zone group for larger multi‐zone sites. The Z28 can be controlled by a PC or up to 3 keypads, or 1 keypad can control up to
14 Z - Range energizers.

What is Bi‐POLAR fencing?

The JVA Z14, JVA Z18 and Z114 Energizers can be programmed to Bi‐Polar mode. This gives rise to the question: What is Bi‐Polar Fencing and what exactly are the benefits of this wiring configuration?

A Bi‐Polar fence is an all‐live wire fence. A Bi‐Polar energizer has the ability to pulse synchronized positive and negative pulses down alternate wires of the same fence line. So, instead of having alternate live and earth wires on the same fence line, one now has one wire with a positive pulse and one wire with a negative pulse. This means that all the wires on the security fence are live with the exception of the open true‐earth wire in the fence grid, should one be included.

A reading taken between the positive pulsing or negative pulsing live wires and the earth, will give half the voltage of a normal live/earth configuration. However, when one touches both the positive and negative pulsing wires, one will receive the ‘full monty’. The big plus factor of this configuration is that, by reducing the voltages to each wire, one helps eliminate the annoying and often difficult‐to‐eliminate arcing experienced in coastal or dusty areas.
