Instruction
The JVA VM2 is a Perimeter Intrusion Detection System utilising Microphonic Cable. The VM2 (PTE0342) is
designed to monitor one or two zones of Microphonic (acoustic) cable to enable the detection of a breach of a
perimeter by detection of noise and vibrations created by unauthorised access or vandalism. The monitored cables
may be buried to detect digging, attached to a fence or placed inside a wall, roof or floor etc. to detect illegal
activity. The VM2, coupled with correctly installed cable creates fully monitored, zoned intrusion detection system.
The VM2 has adjustable threshold and time parameters to allow the installer to tune the system to differentiate
between an intrusion attempt and normal environmental sounds or vibrations. The VM2 complements JVA’s range
of security electric fence energisers and monitors. The VM2 is also compatible with the JVA Z-Series accessories
and software solutions. The VM2 comes with an inbuilt Wi-Fi Webserver which creates a professional Virtual
Keypad ™ for setup and control. A well as providing the features of a wired keypad, the Virtual Keypad ™ is
equivalent to both a user and an installer App, however it does not require any App to be downloaded.
This unit can operate as a stand-alone alarm system through the addition of a Siren and Strobe; however the
addition of one of the optional user Interfaces makes the system more user friendly. These options include a 4-Line
Keypad, Touch Keypad, Perimeter Patrol and the Cloud Router application.
There are a variety of system integration options ranging from low level IO to a HLI based on JVA’s Perimeter
Patrol software.

Example group wiring diagram
Cable Handling
This section contains information on how to make sure the sensor cable is not damaged in handling or installation.
It also shows how to and where to place the cable for best results for a number of typical applications.
Cable care.
Don’t kink it
Don’t knick the outer
Don’t let the core slide out
Don’t stretch or break the core
Joining and terminating the cable
The cable will need to be joined if you are using a non sensitive lead out cable. Such lead out MUST be coaxial
cable such as RG59, Do not use multi-core alarm cable, twin flex or Cat5/6 cable. Even though this system does
not use high frequency it is very sensitive to induced voltages from external sources such as 50Hz mains
electricity.
The conductors in the cable must remain insulated from the earth and any metal structure.
Use a weather proof junction box and standard double entry terminal strip, or a Gel filled cable joiner kit.
Do not run this cable in the same conduit as electric fence lead out cable.
Method for burying cable
The VM2 was designed primarily as an anti-dig sensor system. For best results bury the sensor cable in coarse
sand or gravel. Draft note: this section is not complete.

Method for attaching cable to palisade or wire mesh fences
Draft note: Cable ties, Overlap of zones, Service Loops
Tuning
This section contains information on how to adjust the adjustable parameters to get the best balance between
sensitivity and false alarms.
The VM2 compares the sounds it picks up on the sensor cable to a preset limit called the Threshold. Any sound
that exceeds the adjustable Threshold is called an Event. If the number of Events in a preset Window of time,
exceed the Event Limit then that zone will go into alarm. An extra Event is counted if the signal exceeds the
threshold for longer than the Sample Time. This means that one long loud sound can create several Events. Note
that the front end of the VM2 is done in hardware not sampling software. This means it will not miss an event even
if the event is much smaller than the Sample Time.
The main parameters work in this way:
Parameter

Raising this:

Test Mode
Put the VM2 into test mode, one zone at a time. Using the Virtual Keypad open the Device setup screen, you will
need the Installers PIN to do this, the default is 12345. Click on Test Mode for zone 1 and then 2.
© JVA Technologies Pty Ltd Page 12 of 21 Issue:20/02/2020 9:36:00 PM
Vibration monitor manual.docx
Assuming the cable is attached and properly terminated (the Cable status LED is Green). The LCD will show the
Peak and Average sound recorded and the number of recorded events in each window of time as currently set.
The alarms will not be latched and the siren will not sound. If there is an “Alarm” the number on the LCD will
increment.
Assuming there is a quiet environment what you are seeing on the screen is now your base line measurements.
Hopefully the sound % figures are low and there are no events.
If you have an average level of over 50% something may be wrong. Check that the earth terminal on the VM2 is
connected to a cabinet or site earth. If you cannot reduce this level consider purchasing or borrowing a phone
audio adaptor and recording the sound on this zone onto your phone or laptop. See later section on Recording
using a phone. Draft Note, add this. You may also consider reducing the overall sensitivity of this zone using the
Pad jumper.
If your cable is accessible you can check it is “live” by tapping on the sensor cable. Tapping with a pen should
create a peak of close to 100% and some events and an eventually an alarm.
Create the sounds of an intrusion on your fence or boundary and measure these. You will need someone standing
by the VM2 watching (or recording it with a phone camera).
For a false alarm free system, the sound levels for intrusion events must be much higher than your base level
(normal) sound levels.
Set the zone Threshold above the base level and below the intrusion peak sound level.
Leave the Window setting where it is. Reduce the Events Limit until you are happy that an intrusion sound will
cause an Alarm.
If you change the settings for Threshold, Events Limit or Window, re-enter test mode and check that an intrusion
sound causes an alarm.
Draft note we will need to create some diagrams to make this process easier, or perhaps some videos.
Repeat for the second zone.
Pad
If all the noise levels are too high (the system is too sensitive) you may engage the Pad on this zone (place a
jumper on the Pad pins J11 or J12) to reduce the amplification level (gain) on that zone.
Recording sounds for analysis
The VM2 has an audio output terminal on the PCB. JVA can supply a 3.5mm stereo to 3.5mm headphone cable to
allow you to connect to a smart phone to record the sounds as “heard” by the VM2. You can use any MP3 sound
recording App to do this. Play it back on your phone to make sure the recording has worked.
Send this file to us and we can analyse it for you.
Note: The equipment you use to record the sound should be isolated, i.e. NOT connected in any way to earth. An
Android or Iphone is perfect. A laptop may be used, so long as it is not plugged in to power.
Draft note this is not working on the V0.2 Beta samples.

Keypad Control
The VM2 contains a Virtual Keypad ™. You can use any Wi-Fi enabled device with a browser to access this. See
section x. While mainly designed for configuration the Virtual Keypad ™ may also be used to arm and disarm the
VM2.
The VM2 is compatible with the PTE0240 4-Line LCD and the PTE0230 Android keypad.
Compatibility
If you need to connect this device to a JVA keypad or Perimeter Patrol Software that pre-dates the release of
updates that support this device, you will need to turn emulation on. See options in section ?.
With emulation on the VM2 will appear on the keypad as a generic 2 channel electric fence energiser. The fence
voltage will always who as 0kV. The Zone 1, 2 and gate alarms will display properly as will the warnings such as
ac-fail and low battery. The keypad will be able to arm and disarm the VM2 zones. Programming with a non
compatible keypad will not work, use the Virtual Keypad ™.
To Arm/Disarm the VM2
You may use the control inputs (In1, In2), a keypad, a RF remote control, or one of the JVA software solutions
(Perimeter Patrol or Cloud Router) to arm and disarm the VM2.
When an Alarm Occurs
An Alarm will occur if any of the Zones goes into fault (triggers) while the Zone is armed. If attached, the siren will
sound and the zone strobe will light. This alarm will be indicated on any connected User interface.
The siren will cycle on and off based on the VM2 programming options. The strobe will remain on even after the
VM2 is disarmed. This will turn off when the VM2 is either re-armed, or a User Interface switches it off.
To Silence the Alarm
If there is no Keypad attached simply disarm the VM2 to silence the siren.

Vibration monitor manual.docx
Backup Power
The VM2 may be fitted with a 12V battery inside the case for backup power in case of mains fail. As the VM2 draws
very little power (see section x specifications) a standard 7.5aH battery will last much longer than 8 hours.
Programming Options
Default Installer PIN
12345
The VM2 has non-volatile memory in which programming options (or setup parameters) can be stored. These are
factory pre-set (defaults), but can be field programmed using a JVA 4 Line keypad or the Virtual Keypad ™.

Programming Options in Detail
See the programming options table above. Programmable Options are also known as Configuration or Setup. The
default settings have been chosen to be useful for a “normal” site. If you need to return the unit to default settings
see below (Return to Defaults).
Group ID
A group of Z series devices connect on a wired Keypad Bus must have only 1 master. The other
Energisers/Monitors in the group are slaves. The VM2 should be a master only if it is not in a group with Z series
energisers or monitors. I.e. if it is in a group the VM2 should be a slave.
If a PAE212 TCP/IP adaptor is used, it is the group master. All other devices should be set to slaves.
The VM2 defaults to a master (ID=1) so that it will operate correctly with a Keypad or Gateway.
Threshold (1 and 2).
If the VM2 detects a peak noise over this level it will
register an event. This should be set above the
normal background noise level on your site. This is
often the only setting that will need to be adjusted on
a typical site.
Events Limit (1 and 2)
If there are more than this number of Events
in a single Window of time, then there will be
an alarm. Increase this to reduce false
alarms. Adjust Threshold before changing
this setting.
Window (1 and 2)
This setting determines the amount of time in the moving Window used to count Events. This means that 5 events
spread over a long period will not trigger an alarm. Five events in rapid succession (within the one Window) will
trigger an alarm if the Events Limit is below 5. Reduce this to reduce false alarms. Adjust Threshold before
changing this setting.
DNY (Squelch 1 and 2)
This is not used yet.
© JVA Technologies Pty Ltd Page 19 of 21 Issue:20/02/2020 9:36:00 PM
Vibration monitor manual.docx
Sample Time
This setting can be used to reduce the number
of Events that occur from a single strike to a
fence. This is usually the last setting to adjust of
all those above.
Battery Float Set
The VM2 contains an inbuilt battery charger for a standby 12V lead acid battery. If you are not using the battery
ignore this setting.
This setting adjusts the voltage at which a lead acid battery will be charged and held at when fully charged. Please
consult your battery manufacturers specifications for the correct value.
If power outages are frequent use the recommended cyclic value; typically 14.7V.
If power outages are rare use the standby value; typically 13.7V
Raising this setting will NOT increase the speed at which a flat battery is charged. Setting it too high will damage
the battery.
Note that the temperature of the PCB is used to adjust this value. This assumes a lead acid battery type.
If you are measuring the float voltage at the battery leads using a multimeter, you must do this within 10 minutes of
power up, otherwise the controller will determine that there is no battery connected and show an alarm.
Low Battery Level
Low battery level below which a low battery event is triggered.
Set this to less than 130 (13.0V). Default setting is 110 (11.0V). The Low Battery Alarm will clear when the supply
has increased to 1.0V above the Low Battery Level.
Wi-Fi Enable
Turn this off if you are not using the Virtual Keypad ™. If you wish to secure the virtual keypad, change the WiFi
password using the Virtual Keypad instead.
If you turn this off, you will NOT be able to use the Virtual Keypad ™.
Fire Cycle Time
Not Used.
Input Functions
The defaults are:
Input 1- Arm Zone 1
Input 2- Arm Zone 2
Input Types
The defaults are normally open dry contact.
Alarm Delay (Cable fault alarms)
This sets the amount of time between a cable fault and an alarm. The default is 3 seconds.
Entry Delay
0-255 Seconds of Entry/Gate Delay. Only applicable if an input is set to a Gate input or a general entry zone input.
© JVA Technologies Pty Ltd Page 20 of 21 Issue:20/02/2020 9:36:00 PM
Vibration monitor manual.docx
Exit Delay
0-255 Seconds of Exit Delay. Only applicable if an input is set to a general exit alarm zone input.
Siren on Time
This option sets the duration of time that the siren will remain on after a fence alarm occurs. After this time the siren
will turn off for the Siren Off Time indicated in the table. The siren will sound again if the alarm is still present after
this off time has passed.
The default is 3 Minutes. This may be the subject of local regulations to stop an alarm causing undue
disturbance to neighbours, etc.
Draft note: None of the siren features are work on the Beta Test units
Note: the siren on time will be cut short if the battery falls below the low
Battery level.
Siren Off Time
This option sets the amount of time the siren will be off for after the Siren On Time has expired. If an alarm is still
present after this off time the siren will sound again.
Siren Cycles
This option sets the maximum number of times the siren will sound for the “on time” if the alarm continues. This
may be limited by local regulations to stop an alarm causing undue disturbance to neighbours etc.
Note: This is the maximum number of cycles for 1 continuous alarm, intermittent alarm events could cause more
than this number of siren soundings.
Chime mode
Draft note complete this.
Auto Re-Arm time
This option sets the time which must elapse before another alarm will sound after the first alarm has timed out
(gone completely through its cycles).
If an event occurs which triggers the siren, any other events which would otherwise trigger the siren (such as a
gate alarm) will be ignored while the siren is sounding and until after the Auto re-arm time has passed.
The default is 0 Seconds (Immediate).
Relay Functions
All relays can be set to any of the available functions (user assignable).
The defaults for the VM2 are:
Relay 1 –Strobe 1
Relay 2 –Strobe 2
Relay 3 –Siren (The 0V2 PCB did not have this output)
Relay 4 –Armed (or partially armed)
Relay 5 –Any Zone Alarm
Relay 6 –General Alarm
Return to Factory Defaults
At some point, you may want to return the VM2 to Factory Defaults. To do this remove all power from the VM2.
Remove J4, reapply power and replace J4.
