Page 5: Introduction
JVA ELECTRIC FENCE SYSTEMS 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 electrified fence. - Page 6 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.

Page 10: Equipment Requirements And Options
1. While the Keypad is not essential for normal operation, it is always required for 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. -
Page 11: Operation
OPERATION Status LED Lights The status LED’s on the front of the JVA Zm20 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. -
Page 12: Jva Zm20 Screen Examples
Various problem conditions can also be displayed, such multi-sector as AC fail or low battery. Battery 11.5V When the JVA ZM20 is disarmed after any alarm, the AC Fail last alarm will be displayed until cleared. The display also shows the programmable options and Disarmed values when in programming mode. -
Page 13: Control Options
If an installation contains two ways to control the JVA ZM20/Energizer, then the most recent control signal will determine the Armed/Disarmed state. For example if the JVA Zm20 is armed via the keypad and then disarmed at the control input (IN1) it will disarm. -
Page 14: Keypad Control
JVA ELECTRIC FENCE SYSTEMS The sector in which the fault has occurred will be displayed if the JVA Zm20 has been correctly calibrated. Switching the Key Switch off will disarm the JVA ZM20, although it will continue to display the last alarm and sector. -
Page 15: When An Alarm Occurs
The system will be ready for the next alarm. Note: This silence function will not operate if the JVA Zm20 is part of a JVA Z series in group mode. -
Page 16: To Disarm
Using a Keypad, disarm the system by entering USER PIN and press #. The Fence or Gate light on the JVA Zm20 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 JVA Zm20 next Arms. -

Page 19: Jumper Configuration
JVA ELECTRIC FENCE SYSTEMS Jumper Configuration The JVA ZM20 is equipped with three jumpers, two of which (J3 and J4) operate in an identical fashion to those on the JVA Z14. The third jumper, J5 will suppress the beeper on the JVA ZM20 when fitted. -
Page 20: Fence Wiring Diagrams
JVA ELECTRIC FENCE SYSTEMS Fence Wiring Diagrams There are a number of ways the fence wires can be connected to a JVA Zm20. The following diagrams will outline different ways the ground circuit can be configured and what the benefits of each are. -
Page 21: Earth Stake Monitoring
JVA ELECTRIC FENCE SYSTEMS Earth Stake Monitoring This setup will check how well the energizer is earthed. Connect the Ground Refer- ence input of the JVA ZM20 to the mains earth, or the cabinet earth. Live 1 Earth Live 2 No Earth Monitoring This setup will monitor only the fence return voltages and fence current. -
Page 22: Fence Sector Wiring
JVA ELECTRIC FENCE SYSTEMS Fence Sector Wiring Although series live wiring is recommended, on very long fences parallel wiring may be used. Parallel wiring can result in a fault not being reported if a live wire is cut. If parallel wiring is used, the live wires should be connected in parallel at both ends of the sector. -
Page 23: Using A Sector Divider (Splitter)
Note: When programming the sector splits into the JVA ZM20, place the short to ground on the mid (normally unused) terminal of the Sector Divider. This means that the sector split is recorded at the theoretical midpoint inside the divider and any real fence short will always be outside. -

Power is drawn from the JVA Zm20 battery and 16Vac power supply, or from the EXT 12V input. EXT 12V 2 Way Feed 12V power into this input as an alternative to the 16Vac.

External Relay Box designed to switch a mains Powered Energizer On or Off. Warning: DO NOT use relay 3, 4 or 5 on the JVA Zm20 PCB to switch mains voltage. Mains power must be wired only by licensed electricians. -
Page 27: External Battery And Charger Wiring For 12V Dc Energizers
If the JVA Zm20 is to be used with a JVA Z14 or JVA Z18 the JVA Zm20 should not be configured to control the 12V DC power to the energizer. The energizer and JVA ZM20 should instead be configured in Group Mode and controlled using a Z Series LCD Keypad. -

Page 29: Group Mode Configurations
• Set the Group ID of the ZM20 to Master (2601#), or leave it in Stand-Alone Mode (2600#) A ZM20 by itself does not require the Group ID to be configured as it is factory set to Stand-Alone mode. Z18 with a Keypad •... - Page 30 • Set the Group ID of the first ZM20 to Slave 4 (2605#) A Zm20 requires the use of 2 Group ID values. This is the reason there is a ‘Group ID gap’ between the first ZM20 and the second Z18.
- Page 31 However a 2.5 metre isolation gap is still required between these fences when complying with International Electric Fence Standards. A Zm20 requires the use of 2 Group ID values. This is the reason there is a ‘Group ID gap’ between the first ZM20 and the second Z18.

Page 32: Programming Options
The keypad will beep twice to indicate that the command was accepted. If the PIN was incorrect the keypad will beep 3 times. The LCD on the JVA Zm20 will now show the first programming option and its current setting. -

Ground Voltage rises above this level for more than the missed Pulse Count a Ground Alarm (Sector 2) will occur. When this alarm is triggered, the JVA ZM20 will display the Sector Number of the fault. Fence Cut Alarm 0 Sets the percentage balance change either side of 50% at which the Fence Cut alarm will occur. -
Page 34: Programming Options In Detail
Do not enter the decimal! The default level is 4.0kv (40), maximum is 99. It is not strictly necessary to use the voltage alarm level on a JVA Zm20 as it is primarily a current monitor. Setting this option to 0 effectively turns off fence voltage monitoring. -
Page 35: Fence Cut Alarm Level (04Xx#)
JVA ELECTRIC FENCE SYSTEMS This can be used to monitor for Ground Stake Voltage or Fence Ground Circuit Voltage depending on the fence wiring. This setting is irrelevant if the Ground and Ground Reference Terminals are shorted together. The ground voltage is shown as zone 2 on a keypad. -

KEYPAD ADDRESS ● Connecting Multiple Keypads to a System Up to three keypads may be used to remotely monitor and control the JVA Z Series Security Energizers. To operate correctly, each keypad must be configured to use a unique keypad address. -
Page 44: Notes Regarding Keypad Configuration
JVA ELECTRIC FENCE SYSTEMS The Energizer now needs to be introduced to all of these Keypads. This is achieved by resetting the Energizer using the Keypad (configured to ADDRESS 1), by pressing [USER PIN]*68#. Alternately the power can also be removed to reset the Energizer. -
