Introduction
INTRODUCTION
Please note that although this manual refers to the ZM20, it also applies to the ZM50
which is capable of monitoring up to 50 sectors.
The JVA ZM20 is an advanced security electric fence monitor with the ability to
provide the location of a security breach or fault in the monitored electried fence.
The fault location can be reported as being within 1 of up-to 20 pre-programmed
sectors or as the fault position as a percentage of the total fence length. This allows
for a targeted response by security personnel through manned response or by re-
directing of CCTV cameras.
The JVA ZM20 can reduce the cost of traditional multi-zoned security electric
fences by providing up-to 20 individually reported sectors from one fence energizer/
monitor combination. This can represent a dramatic saving over installing individual
energizers for each zone.
The JVA ZM20 uses digital signal processing to convert power signals into an
accurate distance-to-fault measurement as a percentage of the overall fence length.
When coupled with the JVA
PC based Perimeter Patrol
software, the JVA ZM20 can
identify and report the position
of a fault which can be visually
displayed on a mimic panel
and reported or relayed to
other security management
systems.
The JVA ZM20 is designed
to be coupled with an electric
fence energizer to power the
security electric fence. Unlike
standard security electric
fence energizers, the JVA
ZM20 feeds the fence from
both ‘ends’ which means that
if the fence is cut, the voltage
is maintained on both sides of

Introduction
the open circuit. It also determines the health of the fence by monitoring the voltage,
currents and therefore power owing through the fence. A change in the power ow
can indicate that there is a breach/fault somewhere on the fence. At installation time,
the JVA ZM20 is ‘taught’ the location of the sectors by intentionally placing short
circuits at the joins between sectors. Passive sector dividers can be used to increase
the accuracy of the sector isolation.
By using multiple JVA ZM20’s and synchronised energizers, more than one fence
loop can be monitored in a single installation allowing for vertical zoning and also
providing a degree of redundancy.
The JVA ZM20 has many programmable options which can be adjusted using a
JVA Z series keypad. By correctly setting the alarm threshold levels it is possible
to determine if a fence has been cut or shorted, though only short circuits can be
reported by sector or position.
The JVA ZM20 is fully compatible with JVA Perimeter Patrol for mimic display,
logging, email and more.
The JVA ZM20 is designed to meet or exceed the relevant parts of international
safety standard IEC60335.2.76 by providing complete galvanic isolation between
the fence and low voltage circuits.
The JVA ZM20 is part of the JVA Z series of security products.

Conditions
●The coupled energizer must be compatible with the JVA ZM20. While all JVA
energizers are compatible, the JVA MB8 and JVA MB12 are recommended. If low
voltage monitoring or multi-zoning is also required then the JVA Z14 or JVA Z18 may
be used.
●Energizers with a negative voltage pulse are not suitable
●The JVA ZM20 supports conventional wiring only (not Bi-Polar)
●The coupled energizer output pulse energy must not exceed 18 Joules or be lower
than 3 Joules.
●The maximum impedance of the monitored fence loop which can be accurately
monitored using the JVA ZM20 is 1000 Ohms
●The JVA ZM20 is not yet supported by the JVA GSM interface or by the PAE212
Web Server at the time of publication of this manual (May 2014)
●The JVA ZM20 cannot show a faulted sector if the energizer is operating in low
power mode.

Maximum live wire loop impedance 1000 Ohm
Maximum fence load (leakage) 10 Kilo Ohm
Sector accuracy (See Note 4) 100m or 0.1% of total
wire length
Note 1: This is the power consumption when none of the powered outputs are
active and the keypad is not connected. The rated power consumption may be lower
depending on relay conguration and alarm states.
Note 2: The control inputs, In1, SW2 and Gate supply their own power (5 volts,
limited to 220µA). If a powered control system is connected to these inputs, the
control voltages must not exceed 5 volts.
Note 3: The rated power is the combined output power of both the Siren and Strobe
outputs. The voltage which can be expected on this output is the battery voltage.
The combined maximum output current of both these outputs is 2.5 Amps. Note that
the maximum output power will drop as battery voltage drops.
Note 4: This may not be achieved on all fences.

programming options and sectors during installation.
2. Up to 3 Keypads may be used on a JVA ZM20. Each Keypad must have a
unique ID setting.
3. The Webserver allows for remote control using any web enabled device, but
requires the site to have a wired LAN internet connection. WiFi may be used but
will require a WiFi bridge.

Safety Warning
●The installer is reminded that high voltages are retained for a while after disarming
the energizer and to wait for at least 10 minutes before opening the case. Should it
be necessary to open the JVA ZM20 case ensure that the energizer is disarmed.
● Before working on the high voltage wiring of an electric fence, it is recommended
that the energizer is disarmed and a short circuit is placed from the fence live wires
to earth. This is a sensible precaution against the energizer being armed while
working on the fence.
● The JVA ZM20 contains patent pending technology, contact JVA for more information.
