FOREWORD
The Merlin Range of energizers has evolved over the past fifteen years. The
energizers are designed to comply with the latest international specifications.
In order to offer some product flexibility the embedded software in the
energizers may change. The latest version of documentation and energizer
features can be viewed on our website at: www.nemtek.com
Nemtek has introduced the Merlin Stealth in the course of 2005 to replace the
older M1x and M2x range. Earth-loop monitoring has been incorporated
throughout the range, onboard diagnostics, communications interface
(RS232) and energy output and electromagnetic interference levels that
comply with the very latest IEC specifications.
In August 2006 the Merlin Stealth Master was added to the range. The Master
unit can control and communicate with a maximum of 9 Slave units (M25S or
M28S) which will than form together a 20 zone network system.
Electric fencing can be lethal. Avoi hea contact with the fence. Ask
the installer to explain the options of current limiting resistors, the
programmable output energy levels as well as the low-voltage
operation of the energizer.

INTRODUCTION
1.0 Intro uction
The Merlin Stealth Energizer M25S Master or M28S Master enables up to ten
energizers to be networked.
The system user can send through the Master energizer global or energizer
specific commands to turn energizers On/Off and change between High-
Voltage and Low-Voltage modes. Fence and Gate alarm indication is given for
individual zones on the Master keypad.
Familiarity with the Merlin Stealth Energizer™ Range will facilitate the
understanding of the Master controller.
Each of the networked energizers may have their own individual keypads
giving access to all the programmable features of the individual energizer. For
security reasons, the individual keypads, can be disabled by using a unique
personal identification number (PIN) on each energizer.
The lid tamper switches, mains and battery condition, communication and
synchronization status of each energizer is monitored and displayed once a
second.
For safety reasons the energizers may be pulsed in a synchronized manner.
Communication errors in a network can occur and it is the responsibility of the
user to ensure that the system is in the desired state. If operating as a
synchronized network, system safety is of paramount importance, and any
loss of communication or communication error will result in the affected
network components defaulting to a safe operating level. The Master will
detect a loss in synchronization and take corrective action. The Master will
periodically align the individual energizer clocks to ensure correct operation.

USING YOUR MASTER KEYPAD
Global Comman s
Global Commands are commands from the Master keypad which the Master
and the Slave Energizer must obey simultaneously.
All energizers in the network to obey the commands. The status quo of the
individual energizers is assumed to be that of the master when issuing a
global command .
Example: If a four energizer system with one individual slave in the Off
state. The master and other two slaves are in the On state. Issuing a global
On/Off toggle command will result in all the energizers being in the Off state
because the Master had been in the On state.
ON / OFF TOGGLE (All units)
Enter the Master PIN and press #. All the units should either be on or off.
Verification of all units being in the ON state is if the GOOD indicator is
permanently lit. Verification that all units are in the OFF state is if the ON
indicator is not lit or not flashing. Repeat the sequence if the desired state
has not been attained .
HIGH/LOW VOLTAGE TOGGLE (All units)
Enter the Master PIN and press *3#. All the units should toggle between
High-Voltage and Low-Voltage or vice versa. Verification that all units are in
the High-Voltage state is if the ON indicator is permanently lit. Repeat the
sequence if the desired state has not been attained. If the ON indicator
remains flashing after ten seconds repeat the sequence .

SPECIFIC COMMANDS
Each of the energizers can be instructed to obey specific commands. Without
having to go and physically look at an individual energizer it is easier to follow
the following procedure. If only one energizer is required to be in the OFF
state it is far easier to issue a global command and ensure all energizers are
ON by verifying that the GOOD indicator is permanently lit. Issue the specific
energizer OFF command. Verification is then obtained if the GOOD indicator is
now flashing. If only one energizer is required to be in the ON state, do a
global OFF and check that the ON indicator is not flashing or lit. Turn on the
individual energizer and confirmation is obtained if the ON indicator is flashing
or lit. The same methodology can be used with the High-Voltage and Low-
Voltage commands and the ON indicator. (If this process seems cumbersome,
full status and control, of individual energizers is possible with the embedded
Linux platform).
SPECIFIC ENERGIZER ON/OFF
Enter your PIN (master only) and press the * key, enter the digits 0 and X,
then press the # key. X is the number for the Master or respective Slave unit
and can take on the value as follows: X=1 for the Master unit, X=2 for the
first Slave unit, ditto for the other Slave units up to X=9 for the eight Slave
and X=0 for the ninth Slave.
The GOOD light should flash if one or more energizers are switched off.
SPECIFIC ENERGIZER HIGH/LOW-VOLTAGE
Enter your PIN (master only) and press the * key, enter the digits 3 and X,
then press the # key. X is the number for the Master or respective Slave unit
and can take on the value as follows: X=1 for the Master unit, X=2 for the
first Slave unit, ditto for the other Slave units up to X=9 for the eight Slave
and X=0 for the ninth Slave.
The ON light should flash if one or more energizers are in Low-Voltage mode.

Note*:
The Service/Comms/Tamper indicators refer to the actual energizer address
e.g. a lid removed on the second slave would give a TAMPER 3 indication and
not a TAMPER 5 and 6 indication .
USING KEYPADS ON INDIVIDUAL ENERGIZERS.
If individual keypads are used on slave energizers, the keypads have full
accessibility to the energizer functions. In certain cases parameters are
written to non-volatile memory. Because this process takes an undefined
amount of time synchronization may be lost if the system is a synchronized
network. The energizer will pulse in a safe mode (low-voltage) until the
Master can detect and re-synchronize the network. This typically takes four or
five seconds.
Please note that the Master Keypad does not work on Slave units.
Refer to the Merlin Stealth User Manual for a description of the keypad
operation.

WHAT TO DO IN THE EVENT OF AN ALARM.
A properly installed electric fence should not cause false alarms and any alarm
condition should be investigated.
An alarm condition must be cleared on the Master Keypad. This can be done
by using a specific Energizer On/Off command for the energizer with the
alarm condition or a global On/Off command. If the alarm condition is still
present on turn On the alarm on the Master will sound again.
•Turn the energizer(s) Off and On again at the Master. The Specific
Command is preferable.
•If the alarm does not sound again the alarm condition no longer exists
and no further action is required. If the alarm sounds immediately
again the alarm condition still persists. Switch the specific slave off and
remedy the cause.
Go to the specific energizer and bypass the particular cause of alarm and
remedy when possible. Note that the Master keypad does not function when
plugged into a slave energizer.
Example: A six zone system comprising of a Master and Two Slaves. A
permanent fence fault occurs on Zone 1 of the second slave because a tree
was blown over and has damaged the fence. This would be displayed by a
flashing both FENCE and 5 indicators on the Master keypad with siren and
buzzer activated on both the Master and Slave. Using the specific energizer
On/Off command:
Master PIN*03# i.e. turn energizer 3 (slave 2) OFF.
Master PIN*03# i.e. turn energizer 3 (slave 2) On again.
Because the fence fault persists the alarm will sound again.
Either fix the fence, with the energizer turned off, or go to the energizer and
bypass Fence Zone 1 by entering -Slave Master PIN*11# and repair the fence
at a later stage. Note the Slave Master PIN may or may not be identical to the
Master PIN depending on the installer programming the system. After the
repair turn the Slave back on either at the Slave or at the Master.
Global resets are possible without turning the Energizers Off in the system.

GLOBAL COMMAND: RESET ALL ENERGIZERS (without turning
any of the energizers off an without clearing the in ivi ual energizer memory
con itions)
Master PIN followed by *77#
The individual energizer must first be turned Off and On again to clear its own
specific alarm memory condition prior to issuing this command. The
advantage of this method is that if the alarm condition persists on the specific
energizer the alarm condition will repeat itself on the Master. Failing to issue
the Off followed by the On command to the specific energizer will result in the
alarm condition repeating itself on the Master.
Note: A Tamper alarm requires an Energizer Turn “Off” ( either global or specific
comman ) followe by this option.
