MERLIN STEALTH MASTER Introduction

INTRODUCTION

This manual must read and used in conjunction with the Merlin Stealth Installer

manual.

The Merlin Stealth Energizer™ range of energizers are configurable to be part of a

networked security system. This enables control and monitoring of multiple energizers from

one central location or from any location in the world with internet access.

There is no better electric fence security solution than multiple energizers being connected to

different portions of a perimeter fence. Redundancy can be incorporated and bypassing the

system becomes a lot more difficult. This necessitates the control of output energy and

synchronization of energizer pulsing in order to avoid potentially hazardous conditions.

MERLIN STEALTH MASTER Introduction

In order to facilitate the installation process, and cater from simple to extremely complex

perimeter security requirements, Nemtek offers a range

of products that can be combined to provide an integrated security solution.

This also enables integration into other security systems such as access control and CCTV

systems.

The currently available building blocks are:

Energizer/Controller Related

•Merlin M1XS and M2XS range of energizers. The fundamental building block of an

electric fence. No special software is required when changing from a single energizer

system to a networked system with multiple energizers. The same generic building

block is used.

•Merlin Master M25S and Master M28S. Used for networking up to ten energizers M2XS

energizers. Keypad located at master gives fence indication of twenty zones. Global

and specific commands can be issued from this keypad. Slaves may use individual

keypads as well.

•Merlin embedded linux controller platform. This provides total accessibility to

individual or networked energizers. Permits energizers to become part of a local area

network or to be accessed remotely. A range of communication protocols have been

incorporated to provide flexibility / security and connectivity. Visit www.nemtek.com

for more information and contact details.

Communication Related

•Merlin Stealth RS485/RS232 converter board.

•Merlin Stealth Fiber-Optic/RS485/RS232 converter board.

The remainder of this document discusses the installation of the Merlin M25 and M28 Stealth

Master energizers in conjunction with standard Merlin Stealth Energizers. However, the

networking principals remain the same. An installation using a Master controller can easily be

upgraded to an embedded Linux platform controller.

MERLIN STEALTHMASTER Considerations

Considerations in a Networked Energizer System.

The energizers and controller need to be physically connected. The medium of choice is

fiber-optics, particularly in areas of high lightning incidence. The alternative is a wire based

solution using RS485. It is possible to use a combination of both fiber and copper.

The Physical Layout of the Network:

The fundamental questions to be asked are:

1. Does my budget allow for fiber-optics throughout the network?

2. What is the maximum distance between any two network components? What number

of network components are involved?

3. Is the loss of the communication network between any two network components

allowed to influence the operation of any of the other components? This question is

both security and budget related.

In relation to these questions consider the following:

1. Fiber-optics is the medium of choice from a lightning perspective. It is also ideal for

data communication such as video signals. The cost of increasing the number of fibers

in a cable is not prohibitive. Have a holistic view of access control, CCTV, electric

fencing etc.

2. RS485 has a limit of 1200m before repeaters are required. RS485 has a physical

limitation of 32 devices before some buffering is required. Unlike RS485, fiber-optics is

always configured point to point with only two devices being connected. The standard

Nemtek fiber-optic components have a range of 3km. (It is possible to extend this to

20km.)

3. In order to reduce costs, it is possible to use a single copper cable or optical fiber

cable to connect all the network components. The disadvantage of such a system is

that if the cabling is damaged communication is lost with all devices in the network. It

is also possible to configure the network as a hub with network components being

individually cabled to some central location. It is possible to use a combination of the

different options (see network examples).

MERLIN STEALTHMASTER Defaulting the Energizers

DEFAULTING THE ENERGIZERS

Before the energizers can be configured into a network all energizers have to be put into

their factory default condition.

The Master energizer can only be defaulted with a 20 zone Keypad and the Slave energizer

can be defaulted only with a 1 or 2 zone Keypad.

To default an energizer proceed as follows:

1) Disconnect the Mains from the energizer.

2) Disconnect the Battery from the energizer.

3) Reconnect the Battery and the Mains.

4) Within one minute after reconnecting the Battery and Mains enter the default

code 2389# on the Keypad.

5) The unit should beep four times to confirm that the code is accepted.

If at some later stage the network has to be expanded with additional energizers, it will be

necessary to default the additional as well as all old energizers in the network before the

network can be reprogrammed.

MERLIN STEALTH MASTER Converter card settings

CONVERTER CARD SETTINGS

There are two converter cards available for the communication interface between the

energizers.

1) The Stealth RS 485 converter card.

The card converts RS485 to RS 232.

2) The Stealth Fibre Optic converter card.

This card converts:

a) RS 232 to fibre optics.

b) RS 485 to fibre optics.

The selection between a) or b) is made with a jumper (JP3) on the converter card.

Please note that a single card can not convert from fibre optics to RS 232 and

simultaneously convert to RS 485.

The converter cards have Jumpers (JP), which must be set correctly to make the network

operate properly.

THE STEALTH RS-485 CONVERTER CARD

This card has only one jumper (JP1) which is used to correctly terminate the impedance of

card and cable (twisted pair and earth-screen with a 120 Ohm characteristic impedance). For

this reason it must be inserted at the first and the last network component of the RS 485

system.

The jumper (JP1) must not be inserted on the converter cards which are connected between

the first and the last card.

THE STEALTH FIBRE OPTIC CONVERTER CARD

This card has three jumpers (JP1, JP2 andJP3).

JP1 is used on the card to repeat the optical signal i.e. anything received on the optical Rx

port is immediately transmitted on the Tx port. To prevent that a message is repeated

endlessly JP1 is never inserted on the Master controller. Jp1 is used normally on Slave units

in the Daisy chained systems.

MERLIN STEALTHMASTER Converter card settings

To decide if Jumper 1 should be inserted ask the question if the converter does not repeat

the signal will a message from the Master reach the Slaves and will a message from the

Slaves reach the Master. If the repeating is required insert JP1.

JP 2 is used on the card to correctly terminate the impedances of card and cable.

It must be inserted when the card is the first or the last network component of the RS 485

system.

Do not use the jumper when the card is used for a RS 232 system or if it is used between

the first and last network component in the RS 485 system.

JP3 selects if the card will be used in a RS 232 network or in a RS 485 network.

When the jumper is inserted between position 1 & 2 the RS 485 option is selected.

When the jumper is inserted between position 2 & 3 the RS 232 option is selected.

CONNECTING THE NETWORK

Until some experience has been gained with the system it is better to network all the

network components in the same room. After programming and testing the system, the

components can be installed on site.

Once programmed all parameters are stored in non-volatile memory. Disconnecting the

mains and batteries will not change the stored data.

1) Ensure that mains is available for the energizer.

2) Disconnect the battery from the energizer.

3) Install all converter cards (if required) on the energizers.

4) Ensure that all jumpers are inserted correctly on the converter cards

5) Connect all fibre optic and RS 485 cablesbetween the energizers, for the moment do

not yet connect the RS 232 connection to the energizer.

6) Connect the 12Vdc Aux power from the energizer to the converter card.

7) Connect the 20 zone Keypad to the Master energizer.

8) Connect the 2 zone Keypads to the Slave energizers (if not used one is required for

defaulting the Slave units.

MERLIN STEALTHMASTER Programming the Network

PROGRAMMING THE NETWORK

1) Default all the energizers as described under defaulting the energizer.

2) Enter the Installer Pin on the Master energizer (see Merlin Stealth Installer manual).

3) If the converter card connected to the Master RS232 port connects to the energizers

in the network with:

-Copper (RS 232 or RS 485) enter the key sequence 448#

-Fibre Optics enter the key sequence 449#

4) Select the type of energizer network:

-Synchronized enter the key sequence 440#

-Non Synchronized enter the key sequence 441#

5) After a few seconds the Master Keypad will start flashing the number 2

Led (the Master is always no 1 in the system) and the keypad buzzer will

prompt to connect the first Slave unit.

5) Plug in the RS232 port connector at the first Slave energizer. After a few

Seconds the Master keypad will flash the number 3 Led and the second Slave unit can

now be connected to the system.

6) Carry on until all Slave energizers are connected (maximum 9 units) then enter *#

to exit the programming mode.

The system is now programmed, it is advisable to test if the Slave energizers will obey

commands from the Master keypad and that alarms on the Slave energizers will show on

the Master Keypad.

If a synchronized system was selected ensure that the Slave units will synchronize to the

Master energizer and that they will go to low voltage mode if they are out of sync with

the Master(see Stealth Master User manual).

MERLIN STEALTHMASTER Programming the energizers

PROGRAMMING THE INDIVIDUAL ENERGIZERS

After the network is programmed the Master and Slave units can now individual be

programmed to suit the requirements i.e. gate delay times, siren on times, fence alarm

voltage etc.

If at some stage the network has to be reprogrammed these individual setting will fall back

to the factory setting when the units are defaulted and have to be reprogrammed.

CAUTION

The Merlin Stealth Range, when programmed to be part of a synchronized

energizer network: configures the energizer energy output with the assumption

that only one other correctly programmed energizer, of the same network, may

be touched simultaneously and still remain within the current limited energizer

limits as defined in the IEC 60335-2-76

In other words if a synchronized work is selected the networking program will assume that a

person can touch two fences at the same time and to stay legal the output energy is reduced

during the network programming to half of the maximum energy of the energizer.

If three fences supplied by three different energizers of the same synchronized network

would be within 2.5 meter of each other, the output energy of each of the energizers would

have to be individually reprogrammed to one third of the maximum energy of the energizers

to stay legal.

If an electric fence of a synchronized network is more than 2.5 meter away from other

electric fences the output energy of the energizer supplying that fence can be individual

reprogrammed to the maximum output of the energizer.

Refer to the appropriate regulations and laws pertaining to the installation of

electric fences.
