In today's times, it has become an absolute necessity to safeguard your premises from intrusion.

 

An electric fence is designed just to do that. Not only it's much more aesthetically appealing compared to the conventional barbed wire but it is also much more effective.

 

An electric fence may be installed on top of an existing wall or either right from the ground level upwards. Available with different types of brackets and colours to best suit your premises and the height that may be required.

 

An electric fence can also be used to keep your pets away from flower beds, etc. or at farms to keep animals in or out.

Electric Fence Voltage

The current flow in an electric fence is about 9000 volts per second on average. Due to the fact that the fence works on DC current, the shock is not lethal.

Features
_

Intrusions or Interferences

Should there be an intrusion or interference with the fence wires, the alarm would go off immediately thus giving you an advanced warning and peace of mind.

 

The fence comes with optional galvanized braided wire or stainless steel wire. Different makes of fence energizers are available.

 

Options of digital keypads or remotes to suit your requirements. For rural areas we offer a wide range of solar panels to choose from.

 

All electric fence energizers have battery back-up that typically lasts for about 5 to 6 hours in the event of a power failure.

 

Be it an entry level (5 strand) fence to a stand alone (24 strand) fence, we manufacture and install all different types. We custom manufacture electric fence brackets to suit your taste and requirements. The only company in Johannesburg to introduce colour coded brackets along with wrought iron fancy brackets.

For all electric fence equipment and accessories we strongly recommend Nemtek products

Energizers

The Druid 2, a recent introduction to the extensive range of security energizers, was created for the needs of smaller fence requirements in an urban environment. Many features that are only available on our higher end energizers are now offered as a standard to this range. The Druid 2 can work as a standalone unit using an on/off tag to keep the operation very basic and simple to operate.

Features:

  • 300, 000 pixels night vision camera
  • High voltage monitor will alarm when the live wires are tampered with
  • Earth wire monitor alarms when there is tampering with the earth wires
  • Easy to use tag switch for controlling the unit
  • Connectable to an armed response radio
  • Gate monitor input monitors the position of the gate to indicate if the gate is open
  • Lightning and power surge suppression built in to reduce the possibility of damage due to power surges
  • Battery backup system in case of power failure
  • Intelligent power saving to extend the battery life and save energys

The Druid 13 and 15 offer 3.0 J and 4.6 J output energy and even though they belong to the Druid 2 range, these products offer many more benefits.

Using the Adaptive Power Technology (APT), pioneered and patented by Nemtek, these two energizers offer a new and unique method in detecting how much power a fence can accept and handle before it starts to arc and waste energy, thus maximising the power on the fence.

Changes in the surrounding environment can affect a fences efficiency. The APT actively analyses the fence and adapts the transfer of power as required to ensure maximum performance. These Nemtek energizers are an excellent choice for coastal areas, where the salt build-up during the dry season can result in increased power losses along the fence. The APT feature will modify the output pulse to maximise the transfer of power onto the fence and minimise arcing. The energizer ensures that the fence only receives the amount of power it can manage thus making it energy efficient and economical.

Features:

  • LCD display shows information which is quick and easy to read
  • The background colours of the LCD display, give a quick glance indication of the energizer status without the user having to approach the unit in order to read the display. For example “green” indicates all is fine, “orange” indicates that attention is required and “red” indicates an alarm condition. The coloured lights are visible from a distance, and are quick to spot
  • The Druid LCD range can accept up to two keypads to remotely control the energizer
  • Quick walk test mode on the system offers the installer a quick test facility to walk the fence and test it

Networked Energizers and Communication Accessories

The Merlin Stealth Master energizer, is a dual zone energizer and can control up to nine standard Merlin Stealth dual zone energizers. That means a total of 10 energizers can be controlled together and divided up into 20 fence zones.

Any number of dual zone energizers can be networked, forming a basic 4 zone, 6 zone or up to the 20 zone system as required.

The complete control of the system is done through a 20 zone keypad which is supplied with the Merlin Stealth Master energizer.

Features offered by the 20 zone master controller system

  • The master energizer is also an energizer with two zones thus the cost per zone is reduced
  • It can be configured with any number of energizers that the system requires (max of 10 including the master)
  • Uses existing proven standard Merlin Stealth dual zone energizer units as slaves
  • Multi energizers offer an increased level of security the zones run independently, so even if there is a breach of 1 zone, the rest of the zones will not be compromised
  • Individual slave energizers can also be controlled by the 20 zone keypad
  • Controls the energy output per adjacent zones so that the system does not exceed the maximum legally permissible output

Both the Fiber Optic card and the RS485 cards can be installed inside the Merlin Stealth energizer housing and are powered by the energizer. Fiber Optic cards are the preferred option and must be used in high lightning areas.

Features offered by the 20 zone master controller system

  • The master energizer is also an energizer with two zones thus the cost per zone is reduced
  • It can be configured with any number of energizers that the system requires (max of 10 including the master)
  • Uses existing proven standard Merlin Stealth dual zone energizer units as slaves
  • Multi energizers offer an increased level of security the zones run independently, so even if there is a breach of 1 zone, the rest of the zones will not be compromised
  • Individual slave energizers can also be controlled by the 20 zone keypad
  • Controls the energy output per adjacent zones so that the system does not exceed the maximum legally permissible output

The Sage controller enables multi energizers to be networked and controlled from a multitude of user interfaces, which can be located locally to the system, or anywhere in the world.

The information generated from the Sage controller can then be used in conjunction with our Nemtek Fence Probe graphic package to simplify and increase the users ability to control the system. This system is used in areas requiring

  • a high level of control and flexibility
  • accountability of the operators
  • detailed real time reporting
  • recording and monitoring of the system or systems

Many single energizer sites, such as cellphone towers, electrical switching stations and sub stations, can be controlled from a single security point.

Many options are available when setting up the system, allowing for tailor-made security solutions. Access and control of the security system can be achieved by a computer on the network, mobile phones, PDAs, internet access, dial in and dial out.

Remote Access

  • TCP/IP protocols supported include http, ppp, snmp and ssh, allowing for control of the system through any web browser and secure password control
  • Cellular phones, using GPRS modems offer another feature that can be used to control the system and extract information
  • Local network management, for localised control of the security system

Graphic software and control

The Nemtek Fence Probe software is a graphical user interface for supporting any number of Sage controllers. Utilising the snmp protocol, network management becomes operator independent. A log of all events is recorded automatically. Different events may require different responses and actions. Certain events may require a simple graphical warning on a screen, such as mains failure or gate bypass, whilst others may require the sending of emails and SMS messages to technical support staff.


Cortech Developments is a company that specialises in large scale security and control software (integration). Nemtek�s Merlin Stealth energizer can interface with this software using the Proxy controller. The Proxy allows the electric fence to be interfaced with the Cortech software management systems enabling the electric fence to be part of a larger security system.

Fencing Wires and Cables

Nemtek Stranded Wires

The Nemtek Stranded wires are made of high tensile material making them hard to cut thus increasing the level of security. The flexibility offered by the stranded wire construction makes working with this wire easier during installation and results in a neat clean look on the fence without compromising the fence performance.

  • Galvanised A grade stranded wire, 1.2 mm, 1.6 mm, 2.0 mm. The larger diameters offer lower electrical resistance for longer fence lines, are hard to cut, and have a longer life span.
  • Stainless steel grades 304 and 316 stranded wire, 1.2 mm and 1.6 mm diameter. The stainless steel offers a high resistance to corrosion, giving it a longer life. The 316 grade is the wire of choice for highly corrosive coastal areas.

Nemtek Solid Wires

  • A variety of solid Nemtek wires are available to address the different environmental, mechanical strength, and electrical resistance requirements.
  • Galvanised solid wires, light and heavy galvanised, 2.24 mm diameter. This high tensile wire is generally used for freestanding fencing where a high strength mechanical fence is needed and is generally used for game and animal control fencing applications.
  • Stainless steel grade 304 and 316 solid wires, 1.0 mm, 1.2 mm diameter. Solid stainless steel offers a high resistance to corrosion and a longer life span on the fence, with the 316 grade being the wire of choice for highly corrosive coastal areas.
  • Aluminium solid wire, 1.6 mm and 2.0 mm wire. Aluminium wire has a very low electrical resistance allowing long fences to be powered up from only one energizer and its high resistance to corrosion offers a long life span on the fence.

Lightning and power surge are the most common cause of electronic failure to energizers.

Nemtek energizers have extensive lightning protection built into the units to help reduce the possibility of damage.

Additional external lightning protection reduces the likelihood of surge coming through the fence wires and the mains supply into the energizer thus assisting in the protection of the energizer.

Lightning kits help divert any power surge that may occur on the fence line away from the energizer and into the ground.

Nemtek offers four kits for protecting the energizer from surges:

  • LDK1: Offers protection for a single zone fenceenergizer
  • LDK2: Offers protection for a single zone fence energizer as well as mains protection
  • LDK3: Offers protection for a dual zone fence energizer
  • LDK4: Offers protection for a dual zone fence energizer as well as mains protection
