Introduction
1. INTRODUCTION
Welcome to the world of JVA monitored electric security fences. The proliferation of
non-lethal, monitored, electric security fences in our towns and cities is indicative of
the condence the public has in this form of perimeter security. The reason for this
popularity is simple – monitored electric security fences are effective, economical,
simple to install, and they offer more D’s of security than any other perimeter
system:
D
emarcation
– The JVA fence around your property shows you mean business.
D
eflection
– Would-be intruders will be deected to softer targets.
D
eterrence
– The safe, powerful JVA shock is a strong deterrent to intruders.
D
elay
– The physical barrier will delay an intruder, something they do not like.
D
etection
– The JVA’s voltage monitor warns you of any tampering with the fence.
D
eny
– A well-erected electric security fence will deny entry.
D
ependable
– 60 seconds a minute, 60 minutes an hour, 24 hours a day, 365 days
a year, your JVA electric security fence is monitored by an alert, sober, electronic
watchman.
Every second, the JVA Z energizer
discharges a very short-duration,
safe, high-voltage pulse down
the fence live wire. The JVA Z
energizer then monitors the voltage
at the end of this live wire, thereby
checking that the voltage is being
maintained along the entire fence
line. In the event of a voltage drop
caused by either shorting, cutting
or poor maintenance, the monitor
will trigger an alarm, thus alerting
you.
Manufactured to meet the most
stringent international safety
standards, the JVA Z energizer is
in a class of its own when it comes
to features and benets at an
affordable price.
An electric fence system which
meets current safety regulations

Specications
• There are no user-serviceable parts in this unit.
• There are potentially lethal high voltages inside the Z
Series energizers.
• The high voltage inside the Z Series Energisers may
take a long time to discharge. Wait at least 10 minutes
after turning off before opening the case.
• Before working on the high voltage wiring of an electric fence, it is recom-
mended that the energiser be disarmed and an intentional short circuit
is placed from the fence live wires to earth. This is a sensible precaution
against the energiser being turned on by others or malfunctioning while
working on the fence.
• If an electric fence is part of a multiple energiser system and the distance
between two separate electric fences, each powered by separate energis-
ers, is less than 2.5 meters, the energisers must be congured to operate in
group mode.
WARNING
* A 24Vdc 1.5A supply can be used in place of the 16Vac. The correct connection is +24V to the right AC pin, GND to the left AC pin. Due to the stored
energy in a 24Vdc plug-pack, an AC Fail could occur 5 minutes before the Energiser reports this fault

4.3 LCD Voltage Display
The display on the JVA Z28 shows the voltage at the feed out and return terminals.
Left side = Return zone 1, Right side = Return zone 2.
The LCD also shows the programming option and current setting when in
programming mode. This allows the programming options settings to be checked
easily.
