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

4.8 Internal Beeper/Keypad Beeper
Depending on the chime mode setting, the internal beeper and keypad beeper will
sound when there is a fence alarm, a gate alarm or a general alarm or a door
chime. On at battery the keypad will always beep 4 times before the energizer
automatically enters low voltage mode to preserve the battery. On AC Fail it will not
beep.

JVA ELECTRIC FENCE SYSTEMS
4.9 Cabling
High voltage cabling (fence lead out and returns) should be run using suitably rated
cable. Double insulated electric fence underground cable is suitable. High Voltage
Cables must never be run within the same conduit as Low Voltage Cables. A minimum
distance of 30mm should be kept between High Voltage and Low Voltage cables.
4.10 Lightning Protection
Although the Z28 contains internal lightning protection elements, external lightning
protection elements such as additional external lightning kits available from your
local dealer, are recommended as they would help to reduce lightning damage even
further.
4.11 Earth Loop Monitoring
The Z28 has two fence earth terminals which when wired into a series looped fence
system enable the energizer to monitor the earth circuit. In this conguration, only
one earth spike location must be used. If this is not required the installer can loop the
two earth terminals at the energizer and then connect the earth spikes to one of the
parallel earth terminals.
4.12 Noise and Interference
The Z28 contains a microprocessor. Extreme electrical noise can upset
microprocessors. The most likely cause of such noise is the high voltage output from
the unit itself. In the event of erratic behaviour, check that the high voltage wiring is
rmly connected to the terminals and that no sparking is seen. The Z28 is designed
to self-recover from interference, powering off (both AC and battery) should not be
necessary.
4.13 Programmable Options
The Z28 has many programmable options. These are also known as setup
parameters. To alter these options a keypad must be used. The options are explained
in Programming Options in Brief on page 20. Each parameter has a factory set
default.
4.14 Low Power Mode
Z28 energizers can be switched into low power mode. Low Power mode may be used
in situations where the fence is not required to be a deterrent but is still required to
actively detect intrusion. In Low Power mode the fence live wires operate at a much
lower voltage, typically 500V peak. See Programming Options in Brief on page 20 for
details on using the keypad to set low voltage mode.

4.15 Control Inputs
4.15.1 Control Inputs
The Z28 has 3 control inputs. These default to:
Input 1 – Arm/Disarm
Input 2 – Gate 1
Input 3 – Gate 2 or low voltage mode input.
The gate inputs may be wired to a gate switch to trigger an alarm when a gate is
opened.
If the unit is disarmed, the gate input may be set to chime mode. See Programming
Options in Brief on page 21.
NOTE: If not used, the Gate 1 and Gate 2 inputs must be bridged to the Com terminal.
Inputs 2 and 3 can be congured for other functions. See Programming Options in
Detail, Option 12.
4.15.2 Control Input Functions
On/Off (Arm/Disarm)
When congured as an On/Off Input, the Control Input Arms or Disarms the Fence
Zone. On/Arm will make the Fence Live (High Voltage on the Fence), while Off/
Disarm will make the fence Safe (No fence voltage)
Gate Input
When congured as a Gate Input, the Control Input may be wired to a gate switch to
trigger an alarm when the gate is opened for longer than the Gate Entry/Exit Delay
time (Option 13). The timer will reset to zero when the gate closes. If the energizer
is disarmed, the Gate Input may be set to Chime Mode. See section 9, option 14.
High/Low Power Control
When congured to control High/Low Power mode, the Control Input is able to
change the Energizer Output (While Armed) to either High Power or Low Power
modes. It is also used to determine what Power Mode to start in when the energizer
is Armed using a Control Input.
4.16 Group Simultaneous Pulse Feature
All JVA Z Range models may be linked to form a group to power multiple zones. See
Group Mode, page ??.

12
Installation
JVA recommends installation by qualied technicians.
5.1 Installation Steps
1. Read the entire manual rst!
2. Design and build the fence. (Beyond the scope of this manual.)
3. Decide where the JVA Z28 is to be mounted. If on an external wall it should
be housed within a waterproof equipment box and denitely not in direct
sunlight.
4. Mount the unit by hanging the housing on the two nail-in anchors provided.
If necessary, two extra mounting holes can be used at the bottom of the
housing.
5. If using a keypad, remove the rear housing of the keypad and x it to the
wall.
6. Wire the low voltage cables to the PCB terminals (right side)*. (See page 8)
7. Wire the high voltage cable to the PCB terminals*. (See page 8) If earth
monitoring is not going to be used on the fence, connect a bridge wire from
earth out to earth return.
8. Fit the battery leads to the battery. The Status LED should blink twice to
show mains fail.
9. Mount the 220 – 16V transformer and connect the 16V side to the Z28 16V
input terminals. (AC is not polarity sensitive.) Do not connect a live or neutral
to the earth terminal.
10. The unit is designed not to start when rst powered up irrespective of the
state of the inputs.
11. Replace the front cover.
12. Turn AC power on.
13. Arm and disarm the energizer via the keyswitch or keypad, if tted. The
Status LED should stop blinking.
14. If using a keypad, type *68#. The keypad will analyse the zones.
15. Arm the unit. The LCD display will now show the fence voltage.
16. Check to ensure that a short anywhere on the fence triggers the alarm.
17. On handing the system over to the owner/user, explain how to change the
user PIN. Leave a User Manual with the user.
*NB Keep high voltage and low voltage cables at least 100mm apart.
Do not run high and low voltage cables in the same conduit.

Operation
6. OPERATION
6.1 Arm/Disarm Control
The unit can be controlled by the keyswitch, control input 1 or via a keypad. The
keypad also allows instant audiovisual indication of the state of the energizer and
therefore the fence it is powering.
If there are two ways to control the energizer both connected at once, i.e. keypad and
control inputs, then the last change will determine the result. So if the unit is armed
via the keypad and then disarmed at the control input it will disarm.
6.2 Arming the Fence Using the Keypad
●Enter your USER PIN number (four digits long; default is 1 2 3 4) and push the #
key.
●Make sure the red ARM light comes on.
● The keypad will beep twice to conrm that the system is armed.
●The fence will power up and if all is well (no faults) the system will be ready to
deter and detect.
● If there is a fault on the fence and it cannot achieve full voltage, zone 1 or zone 2
LEDs will ash.
● To disarm the system, enter your USER PIN and press #. This will also clear any
fault lights and zone lights which may have been on.
6.3 Turning to Low Power mode
To switch to Low Power mode, enter your USER PIN and press *41#. In Low Power
mode the fence will still be powered and any breach will be detected, but the voltage
will be much lower than normal operation. The ARM light will ash in Low Power
mode.
Enter your USER PIN and press *42# to switch back to Full Power mode.
Alternatively, the unit can be switched to Low Power mode using control input 2, if it
has been programmed accordingly.
6.4 When an Alarm Occurs
If the system is armed and the fence is tampered with, the corresponding Zone Light
will ash on the energizer and then remain on. Relays assigned to alarms will turn
on. If the energizer is connected to a building alarm system for monitoring, an alarm
signal may be sent to the alarm company monitoring the alarm system.

JVA ELECTRIC FENCE SYSTEMS
16
Operation
An alarm will also sound if input 2 is assigned to the “gate input” function and the
gate input is opened and the entry/exit delay time has elapsed.
After the siren has cycled on and off according to the times and numbers set in
options, the siren will stop sounding. The on and off timing is able to be set in the
options. The Strobe will remain on. After a further delay (Auto Rearm Time) the
siren will again respond to the next alarm condition with a new set of on / off cycles.
If the alarm condition (low fence voltage or gate input) is removed, the siren will stop
after the end of the current “on” time (Siren On Time).
If the siren is muted by (entering PIN#) then the siren will enter the next “off” cycle
(Siren Off Time). If the alarm condition is still present (voltage is low) the siren will
sound again after the preset “off” time. If the alarm condition is not present the
energizer is instantly rearmed, irrespective of the auto-rearm setting.
6.5 To Silence the Alarm
●Enter your USER PIN and press #. This will silence the alarm but not disarm the
system; the Armed Light will still be on. If Auto-Rearm is set, the system will be
ready for the next alarm. Note that the following functions have an effect on alarm
timing: Siren On time, Siren Off time, Siren Cycles, Auto Re-arm time).
● The zone lights on the keypad will ash to show where the breach occurred.
●The siren and strobe are ready to respond again if triggered.
● To disarm the system, enter your USER PIN and press # again. The zone light
will remain lit until the Clear Alarm Memory command (*1#) is entered.
● Alternatively, disarming using the key switch will reset the alarm.
6.6 Changing the USER PIN Number
●Enter the old 4-digit USER PIN and press *0#. This enters User Programming
mode.
●Enter your new USER PIN (must be 4 digits) and then #.
●Press *# to exit User Programming mode.
●Make sure your new USER PIN works by using it to arm the energizer.
●The default PIN is 1 2 3 4.
6.7 Standby Battery
Should there be a loss of mains power, the Power Light on the keypad will go off.
If the loss of power is prolonged, the battery may discharge power and become
ineffective. The Power Light will start to ash indicating a battery low power problem.
If the standby battery requires replacement, the Status Light will ash three times.
6.8 Status Light
If the energizer develops an internal fault, the Status Light will ash a code. See
section 7.2 (page 19).

LCD Keypad Operation
7. LCD KEYPAD OPERATION
7.1 Arming/Disarming the Fence Using the Keypad
Enter your USER PIN (Personal Identication Number: four digits long) and push
the # key. Make sure the red ARM light comes on and the keypad beeps twice to
conrm that the system is armed.
The fence will power up and if all is well (no faults) the system will be ready to deter
and detect.
To disarm the system enter your USER PIN and press #.
NOTE: If there is an alarm sounding you will need to enter your PIN twice, once to
silence the alarm and once more to disarm.
7.2 Keypad Status Display
In normal operation the keypad shows a continuous summary of the system status.
For example if the system is disarmed the keypad will display “Ready to Arm”.
If the system is armed then the keypad will display the voltages for each zone in
the system.
Since there can be many things to display the keypad automatically “scrolls” through
all relevant detail. Each screen is show for about 2 seconds. If you wish to hold the
display at a particular point simple press the [#] key. The auto scrolling will stop for
about 20 seconds.
Pressing the [#] key again will advance the display one step.
If a new trouble (AC fail, low battery etc) or alarm occurs, the keypad screen will
jump to the relevant zone, the keypad will beep (unless toggled off) and auto
scrolling will cease for about 3 minutes.
7.3 Changing the Keypad Messages and Address
The messages and each of the 15 zone labels can be changed.
The Dealer Message displays when the system is on standby.
Zone Labels display after the [#] key is pressed during alarm memory or faults.
The programmable Service Message is displayed during AC failure, communication
failure, or low battery.

displays: “Keypad address __” then change the value by pressing [2] (up) or [8]
(down). Validate by pressing [#].
