Introduction
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 energizers.
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 energizer, the ZLM4 is
wired to the non-energized 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 energizers. 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 JVA Perimeter Patrol software.
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 energizer.
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 device’s
programmable options.
The ZLM4 will report an alarm
on: detecting a low voltage
loop cut (open circuit); shorted
to ground (short); when high
voltage from an electric fence
energizer wire is shorted to
the monitored low voltage
loop; or when two low voltage
loops short to one another
(cross couple).
An electric fence system
which meets current safety
regulations

Limitations
• Any energizer used with the ZLM4 must comply with the IEC60335.2.76
electrical safety standard.
• Energizers with a negative voltage pulse may not be suitable.
• The energizer output pulse energy must not exceed 18 Joules.
• The maximum series resistance of the fence wire loop which can be accurately
monitored is 5000 Ohms.
• Not all versions of the PAE212, PAE224 or PAE218 GSM module recognize the
ZLM4. For compatibility please check with your distributor or JVA.
• The JVA LCD keypad (PTE0210) requires version 2.12 or later rmware to
operate with a ZLM4. The keypad rmware can be viewed at power up or by
pressing *9# on the keypad.
• Perimeter Patrol version 5.2.2 or later is required to operate with a ZLM4.

Operation
OPERATION
Status LED Lights
The status LED’s on the front of the ZLM4 allow the user to ascertain quickly the
current status of the unit and if any action needs to be taken. Below is a brief
description of each LED (top to bottom) and the information it conveys.
Power – On (Green) whenever the unit has power
Armed –On (Red) when the unit is armed; ashes if any zone is bypassed
Fence –On (Red) when there is a fence alarm (any zone); ashes if any
zone has a low voltage
Gate –On (Red) when there is a gate alarm; ashes if the gate is open
Status –Flashes (Red) an error code for service errors; the LCD may also
show an error message

Operation
Control Options
The ZLM4 may be armed and disarmed (controlled) using the following optional
extras:
• Magnetic proximity fob
• Key switch or remote switch connected to the control input (IN1)
• Remote control radio receiver connected to IN1
• Z Series Keypad (LCD or Touch)
• JVA Webserver *not all versions
• JVA GSM module *not all versions
• Windows PC running JVA Perimeter Patrol software
• Low level interface (wired to control inputs and relay outputs) from a third party
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 Webserver, GSM and PC control
software may override the Control Input and Keypad’s methods, depending on the
options used. If you need to make sure that the fence is disarmed (for maintenance),
then using the key switch or keypad alone may not guarantee that the fence will
remain disarmed.
Magnetic Proximity Switch (Optional)
The ZLM4 may be controlled using the JVA Permanent Magnet Key Ring Fob. To
operate, the fob must be held against the control zone marked on the front label. The
energizer will beep and toggle from armed to disarmed or visa versa after the fob is
held in position for 2 seconds. The Magnetic Proximity Receiver should be disabled
in the programmable options if it is not being used.
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 energizer to which it is coupled and begin monitoring the fence.
