JVA ELECTRIC FENCE SYSTEMS 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.
ZLM4. For compatibility please check with your distributor or JVA. • The JVA LCD keypad (PTE0210) requires version 2.12 or later firmware to operate with a ZLM4. The keypad firmware can be viewed at power up or by pressing *9# on the keypad. •...
1. While the keypad is not essential for normal operation, it is required to adjust the programmable options. 2. Up to 3 keypads may be connected in parallel on a ZLM4. Each keypad must have a unique ID setting. 3. The ZLM4 contains patent pending technology. Contact JVA SA for more information.
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.
JVA ELECTRIC FENCE SYSTEMS ZLM4 LCD Screen The ZLM4 will show the status on the optional LCD display. When disarmed: JVA ZLM4 Disarmed While armed, the LCD display cycles the following information: 1: 35V 2: 37V ZLM4 Armed Battery 14.5V...
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.
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.
• Will respond to *68# to analyse the ‘group’. • Version 1.21 and below – Older version, can be upgraded to V2.00 firmware – Cannot detect or operate with the ZLM4 • Version 2.20 and higher – ZLM4 is supported, zones are displayed...
The system will be ready for the next alarm. NOtes: 1. This silence function will not operate if the ZLM4 is part of a Z series networked group. 2. The last alarmed Zone will still be displayed on the front panel LCD and the keypad.
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.

3. This is the limit for the combination of the loads on both the Siren and Strobe outputs. 4. This is the maximum rating of the energizer if the ZLM4 is used on the same fence as a high voltage electric fence energizer. Beyond this rating the ZLM4 loop circuit protection MOV’s may fail if high voltage wires are shorted to the...
15. Arm the ZLM4 and switch on the energizer 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.
JVA ELECTRIC FENCE SYSTEMS Jumper Configuration The ZLM4 is equipped with three jumpers, two of which (J3 and J4) operate in an identical fashion to those on other Z-range energizers. The third jumper, J8 will suppress the beeper on the ZLM4 when fitted.

• Insulated wire buried underground; the alarm is given if the insulated wire is cut or shorted to earth. Low Voltage Zoning System The ZLM4 uses interleaved low voltage wires of the fence to detect any tampering. Security ZLM4 Energizer...
A ZLM4 can be combined with JVA Z series energizers to power the fence. The ZLM4 should be configured as a slave and the Z series energizer as the master. The number of Z series energizers and ZLM4 is limited by the available ID numbers if using the keypad bus.
• 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 energizer driving it. A ZLM4 by itself does not require the Group ID to be configured as it is factory set...

To enter programming mode, enter the 6 digit installer PIN followed by *0# keys. 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 ZLM4 will now show the first programming option and its current setting.
A Group containing Z-Series energizers and ZLM4s MUST NOT be programmed this way as the ZLM4 contains different Option values to the Z-Series energizers. Each ZLM4/energizer will need to be isolated from the Group Wiring and programmed individually.

JVA ELECTRIC FENCE SYSTEMS Keypad Programming Changing the Keypad Messages and Address The messages and each of the 15 zone labels can be changed. The Dealer Message displays when the system is on standby. Zone Labels display after the [#] key is pressed during alarm memory or faults.
JVA ELECTRIC FENCE SYSTEMS The message order is: SERViCE MESSAgE (Displayed under ‘System Trouble’) • DEALER MESSAgE (Displayed under the standby message: ‘Ready to Arm’) • • ZONE NAMES bAuD RATE (should be left at 2 400) • KEYPAD ADDRESS (should be left at 1) •...
JVA ELECTRIC FENCE SYSTEMS Notes Regarding Keypad Configuration Zone 1 (the master) must be connected to the group. If it is not connected the other energizers in the group will not send status packets to the keypad. The status packets contain voltage and alarm information which the keypad displays. If Zone 1 is not connected, the keypad will report a communications failure with all the zones.
Whilst every effort has been made to check that the information contained is accurate, JVA Technologies Pty Ltd will not be liable to loss or damage resulting from construction, operation or failure of any installation or system. Installation of security electric fences should be made by trained professionals with regard to the relevant local standards and workplace health and safety requirements.
