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).

ZLM4 LCD Screen
The ZLM4 will show the status on the optional LCD display.
When disarmed
While armed, the LCD display cycles the following information.
Pressing # on the keypad will freeze the current information displayed on the LCD screen for approximately 10
pulses. Pressing the # key again will cycle the display to the next information screen.
When an alarm occurs the screen will detail the type of alarm and the sector if applicable.
Various “troubles” are also displayed, such as AC fail or low battery.
When the ZLM4 is disarmed, all current alarms are shown.
The display also shows the programmable options and values when in programming mode.

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.

•Refer to the inbuilt help, the rest of this chapter refers to the simpler LCD keypads above.
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.
