INTRODUCTION
The ZLM4 is a 4 zone low voltage electric fence monitor. The ZLM4 may be used by itself or in conjunction with a
number of high voltage security electric fence energisers. The ZLM4 monitors up to 4 loops of fence wire, each up
to several hundred meters long, to detect someone tampering with the fence by cutting or shorting the wires.
When used in conjunction with a high voltage electric fence energiser the ZLM4 is wired to the non energised earth
wires on the fence. In this way the ZML4 can be used to split one high voltage zone into up to 4 low voltage
monitored zones for improved targeting of the response to potential security breaches.
The ZLM4 is compatible with the JVA Z series energisers. It may be connected via a Keypad bus network with
other Z series devices to enable the whole group to be controlled via one keypad, or linked to a PC running
Perimeter Patrol.
The ZLM4 monitors a low voltage loop using intrinsically safe, isolated ELV DC. It employs a continuity check for
detecting open circuits, DC voltage level sensing to detect a short to ground and pulse voltage sensing to detect a
short to a line powered by a high voltage fence energiser.
The advanced features of this device allow the performance to be tuned to the fence and to the particular
requirements of the site. This is done by adjusting the devices programmable options.
The ZLM4 will report an alarm on seeing a low voltage loop cut (open circuit), shorted to ground (short), when high
voltage from an electric fence energiser wire is shorted to the monitored low voltage loop or when two low voltage
loops short to one another (cross couple).

Control Options
The ZLM4 may be armed and disarmed (controlled) using a:
•Key switch or remote switch connected to the control input (IN1)
•Remote control radio receiver connected to IN1
•Z Series Keypad
•Smart phone linked to a Cloud Router account
•Windows PC running JVA Perimeter Patrol
•Low level interface (wired to control inputs and relay outputs) from a third part security alarm panel or
Physical Security Information System (PSIM)
Note: More than 1 method may be used in the one installation.
Control Arbitration
If an installation contains two ways to control the ZLM4, then the most recent control signal will determine the
Armed/Disarmed state. For example if the ZLM4 is armed via the keypad and then disarmed at the control input
(IN1) it will disarm.
The higher level control methods such as the PC control software may override the Control input and Keypads
methods, depending on the options used. If you need to make sure that fence is disarmed (for maintenance) then
using the Key switch or keypad alone may not guarantee that the fence will remain disarmed.
Control inputs
The ZLM4 may have a single Key switch mounted on the right hand side of the cabinet which may be used to arm
and disarm the security electric fence to which it is connected. This switch is useful for the simplest
implementations where no keypad or PC control program is used. It may be disabled by the installer, by removing
the lead from socket J2.
When switched on via the Key switch (or a switch connected to IN1) the ZLM4 will power up the energiser it is
coupled to and begin monitoring the fence.
The screen will change to display the Armed status and any faults or alarms. If there is a fence fault the ZLM4 will
go into alarm, the internal beeper will sound (if it has not been inhibited) and any siren and strobe connected to the
ZLM4 will be turned on.
The zone in which the fault has occurred will be displayed.
Switching the Key switch off will disarm the ZLM4, though it will continue to display the last alarm and zone.
Keypad Control
The ZLM4 uses the same keypad as the Z series
energisers and is controlled using similar keypad codes.
The PTE0210 keypad (Version 2.00 and higher) will
display the Fence voltages plus the zone if in fence
alarm.
Alarms and troubles will also be displayed.
The Keypad has two LED lights
Power
On with Mains power, Off with Main
fail, flashes on low battery
Armed
On when the energiser is armed,
flashes when in low power mode
All other indication is given via messages on the keypad
LCD screen.
If the Keypad shows “Alarm” or “Trouble” pressing [#]
will reveal more information about the problem.
NOTE: There is no panic function currently implemented.

Arming/Disarming the Fence Using the Keypad
Enter your User PIN (Personal Identification Number: four digits long) and push the # key. Make sure the red ARM
light comes on and the keypad beeps twice to confirm 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.
See also the section on programming Keypads.
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.
When an Alarm Occurs
An Alarm will occur if there is a fault on the fence caused by a short or an open circuit (cut), while the system is
armed. The siren will sound and the strobe will light. The internal beeper and the Keypad may also sound,
depending on how your system is configured.
There are 3 ways the ZLM4 can detect a fence fault:
1) A low voltage circuit is cut (open circuit)
2) A low voltage circuit is shorted to ground (LV short)
3) A high voltage wire shorts to a low voltage wire (HV Short)
Note: If the ZLM4 is monitoring a fence that has a disarmed energiser on it, a ground alarm will occur when one of
the HV wires touches a LV wire. This is because the ZLM4s pulse will ground through the energisers transformer.
Whilst the ZLM4 is correct in stating that there is a ground short, please be aware of this when diagnosing fence
faults.
The siren and keypad beeper will sound and any relays assigned to this fence alarm will turn on.

© JVA Technologies Pty Ltd Page 11 of 32 Issue:3/03/2021 9:39:00 AM
OEM technical manual.docx
An alarm will also sound if Control Input 2 is assigned to the “gate” function and the gate input is opened for longer
than the Gate delay time.
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 can be set in the programmable 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 is removed, the siren will stop after the end of the current “on” time (Siren On Time).
If the siren is silenced (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 Energiser is instantly rearmed, irrespective of the auto-rearm setting.
To Silence the Alarm
If there is no Keypad attached simply disarm the ZLM4 using the Key switch or magnetic fob.
Using a Keypad, enter your User PIN and press #. This will silence the alarm but not disarm the system; the armed
light will still be on. The system will be ready for the next alarm.
Note: This silence function will not operate if the ZLM4 is part of a Z series “group”.
The last alarmed Zone will still be displayed on the front panel LCD and the Keypad.
The siren and strobe are ready to respond again if triggered.
To Disarm
If there is no Keypad attached simply disarm the ZLM4 using the Key switch or magnetic fob.
Using a Keypad, disarm the system by entering your User PIN and press #.
The Fence or Gate light on the ZLM4 will remain on to show the Alarm memory. This can be cleared by entering
the Clear Alarm memory command *1#. The Alarm memory will also be cleared when the ZLM4 next Arms.
To Clear Alarm Memory
After an alarm occurs, pressing *1#, will clear the alarm memory. If the problem still exists the unit will alarm again.
Changing your User PIN
Enter the current 4 digit PIN and press *0#. This enters User Programming mode.
Enter your new PIN (must be 4 digits) and then #.
Press *# to exit User Programming mode.
Make sure your new PIN works by using it to arm the energiser.
The default User PIN is 1234.
For example, the following Keypad sequence will change the User PIN to 8015 from the default PIN:
1 2 3 4 * 0 # 8 0 1 5 # * #
Standby Battery
Should there be a loss of mains power, the Power light on the keypad will go off. The status LED on the ZLM4 front
panel will flash twice and the Keypad will show Trouble –AC Fail.
If the loss of power is prolonged, the battery may become discharged and become ineffective. The Power light on
the keypad will start to flash indicating that the battery charge is low. The status LED on the ZLM4 front panel will
flash three times and the Keypad will show TROUBLE: LOW BAT
If the standby battery requires replacement, the Status LED on the Energiser will flash 3 times even after the mains
power has been restored.
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, a general alarm or a door chime. On flat battery the keypad will always beep 4 times before
the energiser automatically enters low power mode to preserve the battery. On AC Fail it will not beep.
Note: The Internal beeper also beeps at Power up.

INSTALLATION
It is recommended that all installations are performed by qualified technicians.
Installation Steps
1. Read the entire ZLM4 and Energiser manuals first!
2. Design and build the fence. (Beyond the scope of this manual.) Ask your distributor for help if required.
3. Decide where the energiser, ZLM4 and Keypad are to be mounted. If on an external wall it should be
housed within a weatherproof equipment box, shaded from direct sun.
4. Remove the lid of the ZLM4 using a 5mm Hex key.
5. Remove the ZLM4 PCB chassis from the housing by removing the two screws at the top corners.
6. Mount the housing by using 4 screws through the rear of the box. The box must be mounted to a wall
in such a way that all of the 4 holes in the rear of the case are against the mounting surface.
7. Replace the PCB chassis.
8. If using a keypad, remove the rear housing of the keypad and fix it to the wall.
9. Wire the low voltage cables to the PCB terminals.
10. Wire the high voltage cable to the PCB terminals.
11. Set the Jumpers as required
12. Fit the battery leads to the battery. The Error LED should be blinking twice to show mains fail.
13. Replace the front cover (lid).
14. Turn AC power on.
15. Arm the ZLM4 and Switch on the Energiser if used. The LCD display will now show the zone voltages.
16. Find and remove any faults on the fence
17. Test that a short in any zone puts the ZLM4 into alarm and shows the correct Zone

Fence Wiring Diagrams
Standalone fence continuity monitor
The ZLM4 may be used to monitor a loop of wire on or under a perimeter fence.
•Bare conductors on insulators as per high voltage electric fence, but powered by the ZLM4 low voltage
monitor for sensitive environments such as public areas.
•Insulated wire woven through balustrade or chainmesh fencing. The alarm is given if the insulated wire is
cut or shorted to earthed metal.
•Insulated wire buried underground. The alarm is given if the insulated wire is cut or shorted to earth.

Wiring Diagrams
Combining the ZLM4 with a Z Series energiser
A ZLM4 can be combined with JVA Z series energisers to power the fence. The ZLM4 should be configured as a
slave and the Z series energiser as the master. The number of Z series energisers and ZLM4 is limited by the
available ID numbers if using the keypad bus, it is unlimited if using TCP/IP.

Keypad Bus Wiring
•Set the Group ID of the Z18 to Master (2601#)
•Set the Group ID of the ZLM4 to Slave 1 (2602#)
The Group ID of the ZLM4 must be 1 value higher than the Group ID of the Z-Series Energiser driving it
A ZLM4 by itself does not require the Group ID to be configured as it is factory set to Stand-Alone mode
