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.

Mounting & battery replacement
7
STEP 1: Disconnect mains. Open the lid after
removing the two cap screws. Unplug the
battery terminals if connected.
STEP 2: Remove screws and battery bracket
STEP 3: Remove battery
*Dispose of old battery according to legal
requirements. Do not replace with a non-
rechargeable battery!
STEP 4: Use a drilling template and drill 4 x
8mm holes in the wall for mounting the unit.
Four nail-in anchors are supplied with the unit.
Insert the plastic sleeve of the nail in anchor
into the wall then hammer the screw in with a
screwdriver and hammer. Leave a gap slightly
more than the thickness of the casing between
screw heads and wall. Position the casing so
that the screws go through the slots provided
then drop it into position. Tighten the top 2
screws to secure the casing. The bottom two
screws will slot into the casing for stability,
they don’t need to be tightened.
STEP 5: Insert battery with the negative
terminal to the top.
STEP 6: Place the battery bracket back (with
plastic offsets at the top) and fasten the
screws into place.
STEP 7: Connect battery wires. Close the lid
by hooking the top of the lid in first and then
fasten the bottom down with the two cap
screws. Apply mains power to the unit.
Note: Unit to be mounted vertically against a flat
surface, in a well-ventilated area.
Avoid prolonged exposure to direct sunlight.
