INTRODUCTION
The DRUID LCD 20 is a low voltage (less than 50V peak), fence monitoring system, which will
alert the user if a fault condition (open-circuit or short-circuit) is introduced to the fence. For
increased security the DRUID LCD 20 can be used in conjunction with an electric fence
energizer, provided the energizer output energy is 8 joule or less.
The unit is battery (12V 7AH nominal) operated and suitable for connection to mains power
(AC 100V-240V, 50-60Hz).
The batteries to be used are rechargeable lead-acid batteries. Non-rechargeable batteries must
not be used. The lead-acid batteries require venting and it is imperative that the unit be
situated in a well-ventilated area. A new fully charged battery will typically provide in excess of
24 hours backup.

The DRUID LCD 20 should ideally be operated by means of a remote keypad to obtain
access to the many monitoring features and receive the greatest protection. It can
however be operated by means of a NEMTEK tab or external switch.
The unit includes many user and installer settings. These will be retained in the event of
total power loss, like when the battery is exhausted during a prolonged mains failure.
The unit can be configured as a master only, 2 zone installation, or as a master and slave
networked 4 zone installation. Only a master unit can communicate with keypads and
other devices present on the keypad bus.
A set of jumpers positioned above each of the three unit’s relays, allow the relay contacts
to be configured as either wet (providing 12V nominal power) or dry (potential free)
contacts.
The unit’s display will light with a blue (OFF), green (all is OK), yellow (alarm in history or
other medium priority event) or red (active alarm condition exists) background to
announce the system state at a glance and from a distance.
NEMTEK Connect
NEMTEK Druid LCD 20 units can be upgraded for remote connectivity through a
smartphone application or internet browser via NEMTEK Connect. Contact NEMTEK for
more information on the hardware and software upgrades required.

The Druid LCD D20 can be connected to a standard electric fence installation, as a low
voltage substitute for an electric fence energizer. The installation and erection of an electric
fence in, South Africa, is to be done according to the latest addition of SANS 10222-3.
In other countries, according to relevant specifications.
Live wire connection

The Druid LCD 20 can also be connected to an electric fence in conjunction with an electric
fence energizer for added security. Ensure that the output energy of the electric fence
energizer is 8 joule or less to prevent damage to the Druid LCD 20. Always consult the
installation manual of the energizer before installation.

CREATING A 4-ZONE INSTALLATION
Using two DRUID LCD 20 units, or a DRUID LCD 2x energizer and DRUID LCD 20 unit, a
four-zone installation can be created. Implementing four zones, a property owner can
identify the location of an attempted intrusion to a greater degree of accuracy. For
example, the front, back, left or right side of the property can each be a unique zone.
To create a four-zone system, the two units need to be linked via the keypad bus by
connecting the system ground (KEYPAD-) wires and the data wires (DATA) together (see
diagram on page 9).
One unit must be configured as a master, and the other unit configured as a slave. A unit
is configured by means of a Master/Slave jumper on the main PCB, just below the LCD
display. A master will have the jumper absent, and a slave must have the jumper inserted.
When a DRUID LCD 2x energizer and a DRUID LCD 20 are connected together, the DRUID
LCD 2x energizer must be set as the master and the DRUID LCD 20 as the slave to prevent
the energizer from generating a synchronisation loss fault.
Master will show as zones 1 & 2 on the keypad.
Slave will show as zones 3 & 4 on the keypad.
Lastly, the master needs to be informed whether a slave unit is connected, creating a four-
zone system or if it is a master only, two-zone system. This is to allow a communication
failure (service alarm) to be generated should the slave unit not respond to the master’s
request for information, and so that the keypad can be dealt with correctly as either a two-
or four-zone installation.
The SLAVE UNIT PRESENT setting is set by first entering installer mode, and then
entering installer code 5001*#. Further details of this code can be found in this manual
under the PROGRAMMABLE OPTIONS section.
Note: Please read the section, KEYPAD ZONE FOCUS, in the Druid LCD 20 User Manual. This
section explains how to direct keypad inputs to a specific zone, or to all zones simultaneously.
Installer PROGRAMABLE OPTIONS which are zone focus specific will have the following text
appear bellow the programmable option later in this manual:
“Can be directed to a specific zone, using KEYPAD ZONE FOCUS”

The Druid LCD 20 has a data port to which communications cards, such as a network card
or a NEMTEK Connect card, can be connected. These cards enable networking or remote
access and control of the unit.
Visit the NEMTEK website, www.nemtek.co.za, for the latest details on the smartphone
app and networking options available to you.
Network cards and NEMTEK Connect

A total of 32 Druid LCD 20 units or Druid LCD 2x energizers (64 Zones) can be networked
together.
Each of the units will need to have a unique address in the range 1-32.
The unit’s large network address is set using installer code 51??*# detailed on
page 28 of this manual.
Please read the energizer synchronisation requirements in the Druid LCD 2x Installer
Manual if more than one energizer is connected to the network.

Solar installation
The Druid LCD 20 can be powered using a solar power installation, instead of mains
power. Always use a good quality 12V solar regulator with an output power rating of at
least 50W. The unit must be configured for solar installation by entering the keycode
4071*# (refer to keycode description later in this manual).
Note: If the Druid LCD 20
has a Nemlink Ethernet
card installed, a separate
earth spike, not connected
to the fence ground, must
be installed at least 2m
away from the fence earth.

Main Fuse: Unit displays a battery symbol, and not the mains power symbol (plug).
Battery Fuse: Unit does not operate when mains power is disconnected.
Aux Fuse: The Siren and strobes do not function.
When the unit’s front cover is opened while displaying a service condition (spanner
symbol), and the service condition is still present, further information will be displayed
indicating the cause of the service condition as listed below.
A = Aux fuse blown
B = Battery fuse blown, battery fault or not connected
N = Slave unit communication failure
FUSE DESCRIPTION AND FAULT SYMPTOMS
All fuses are of the “fast blow” type. The Main fuse has a 4A rating, while the Battery and
Aux fuses have a 2A rating.

• Keep the wires to the fence separate from the keypad, gate, siren, strobe and
mains wiring.
• Do not try and modify the unit. Any unauthorized modifications will null and void
the warranty and possibly render the unit illegal.
• If the external On/Off facility is used, the wire between the remote switch and the
unit can be up to a 100m in length. The switch contact must be open for the fence
to be monitored.
• A remote receiver can obtain 12VDC from the keypad bus. Current consumption
must not exceed 0.1 Amps. This is not sufficient to supply power for an armed
response transmitter.
• The siren and strobe light total current consumption should not exceed 1.8Amps.
• Never use the unit’s battery to power a radio alarm transmitter or alarm panel.
• The wire between the magnetic gate switch and the unit can be up to a 100m in
length, but must not run parallel with any fence wires. The gate switch must be
open circuit if the gate is open.
• The remote keypad cable must not exceed 100m in total length. Avoid running this
cable parallel with any fence (high voltage) wires.
• You may connect a total of two keypads, one expansion card and one slave unit to
a DRUID LCD 20 set to master.
• Use HT (high voltage) wire between the fence and the DRUID LCD 20, including the
earth wire. Never run these wires in the same conduit or through the same hole as
the low voltage wiring.
• Always use ferrules or line clamps to connect two fence wires together. Avoid using
dissimilar materials for connections like copper on steel.
• When replacing the front of the unit, hook the top in first while holding it an angle
and then push it closed at the bottom. Fasten the lid down with the two cap
screws.
• Always test the fence after installation for correct short and open-circuit alarming at
various points along the fence.
• Do not use the unit with non-rechargeable batteries.
• The unit contains a sealed lead-acid battery that will vent to the atmosphere under
certain conditions. For this reason, it is imperative that the unit is installed in a well-
ventilated area.
• Do not use this unit in conjunction with an electric fence energizer of which the
output energy exceeds 8 joule.
• Refer to the applicable laws concerning the installation of electric fences in your
area.
