2 INTRODUCTION
Thank you for purchasing a JVA security Low voltage monitor. The growing
use of non-lethal electric security fences around the world is indicative of
the confidence security professionals are placing in this form of perimeter
security. The reason for this popularity is simple – monitored electric se -
curity fences are effective, economical, simple to inall and they offer more
D’s of security than any other perimeter system:
DEMARCATION - The JVA electric fence around your property shows you
mean business.
DEFLECTION - Intruders are deflected to softer targets.
DETERRENCE - The safe, powerful JVA shock is a strong deterrent to intrud-
ers.
DELAY - The barrier will help delay an intruder, giving you more time to
react.
DETECTION - The JVA’s voltage monitor warns you of any tampering with
the fence.
DEPENDABLE - 60 seconds a minute, 60 minutes an hour, 24 hours a day,
365 days a year, your JVA electric security fence is monitored by an alert,
sober, electronic watchman.
The ZLM1 is a single zone low voltage electric fence monitor. The ZLM1
may be used by itself or in conjunction with a number of high voltage se -
curity electric fence energisers. The ZLM1 monitors a single loop of fence
wire reaching out 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 energiser the ZLM1 is wired
to the non energised earth wires on the fence. The ZLM1 is compatible
with the JVA Z series of energisers. It may be connected via a keypad bus
network with other Z series devices to enable the whole group to be con-
trolled via one keypad, or linked to a PC running Perimeter Patrol or Cloud
Router. The ZLM1 monitors a low voltage loop using intrinsically safe, iso -
lated ELV DC. It employs a continuity check for detecting open circuits, DC
voltage level sensing to detect a short to ground and pulse voltage sens-
ing to detect a short to a line powered by a high voltage fence energiser.
An additional high voltage isolated port included on the ZLM1 allows for
external electric fence voltage monitoring. If paired with a JVA Z series en-
ergiser the system can then be synchronised to pulse together with the ex -
