1.    How can a fence be financed?

Elf provides the funding to install the fence. Elf then calculates a repayment     

schedule and adds the cost of maintenance and insurance           

to this figure.

2.    Why finance a fence?

Fences that are not financed often fall into disrepair and the original      

installer is nowhere to be found. Elf has vested interest in a financed     

fence because if it does not work, the client can withhold payment. In    

addition, the incentive for Elf to build up a top quality fence is high         

since it has committed to a fixed cost maintenance program i.e. any       

additional costs are for Elf’s account.

3.    How long does the contract last?

Typically 60 months, although this is structured to meet the client’s       


4.    What other costs does the Client incur?

None. Elf is contractually obliged to fix the fence at its own costs. Elf     

takes out comprehensive insurance for this which is included in the       


5.    What happens if the fence is cut in the middle of the night?

Elf is on duty 24 hours a day. As soon as Elf is notified, a technician will           

be sent out to repair the fence. If a vehicle has been driven through the

fence, Elf will make provision for a guard to be placed at the breach       

until it is properly repaired.

6.    When considering an electric fence installation, what is important?

  • Spacing of strain poles and intermediates posts
  • Spacing of wires
  • Type of wire
  • Method of monitoring
  • Maintenance
  • Etc

7.    How does an Alarmed Perimeter Fence work?

There are two types of alarmed fences:

  • Electrified High Voltage fence with a maximum of 10,000 volts, and   
  • Electrified Low Voltage fence with a maximum of 36 volts

Each of these fences work in the same way – a current is induced into   

the fence and the return voltage is measured to determine whether the  

fence has been cut or short circuited. The high voltage fence gives the   

intruder a shock, whereas the low voltage fence does not.

8.    Wiring and Configuration

There are a number of types of wire to use namely aluminium, galvanized steel,            

galvanized braided steel and stainless steel. These come in various thicknesses and

have different characteristics.  The resistance of the wire is of great importance

when installing electric fencing.

A fence can be wired in two configurations namely parallel or series. The         

series wiring configuration offers the greater protection for security purposes

as the cutting of the fence is more easily detected. The parallel configuration is          

used when the security threat is low or when the fence resistance has to be  


9.    Alarm Reporting

Longer fences are generally divided into zones so that the guard can        

identify the area breached and respond accordingly. Systems are set up to       

detect the breaches in a number of ways namely hard wired zones, resistance

configured zones or comparative current flow detection zoning. It is important            

to ensure that the system accurately indicates the area breached and indicates            

 the correct zone if a number of zones are breached in succession.

10. Reaction to Alarms

  An alarmed perimeter is only as good as the response to the alarm. A clear      

document of procedure should be drawn up detailing the procedure of events

in the case of an alarm being raised.

11. Alarm Testing

  All zones on the fence should be tested regularly, checking to see that signals

are received at the guardhouse as well as the control room of the armed           

response provider. Alarms should be logged and signed off by the relevant      


12. Monitoring and Maintenance

Electrified fences are dynamic installations that require maintenance. In order

to ensure that the required maintenance is done before the criminal finds out   

that the system is not working, the fence must be monitored. A program or      

procedure should be followed to ensure that the system is fully functional.

Everybody loves to go on holiday, but none of us want to arrive home to find we have been burgled. In the rush to get away, it´s easy to forget the simple steps that can help keep your home safe and secure beyond just locking the door.

“Home Secure” checklist:

  • Ensure that all ground and basement windows are fitted with locks and make certain doors have dead bolt locks.
  • Secure sliding glass doors with a metal bar or wooden dowel placed in the door track.
  • Leave curtains slightly parted so your house doesn’t have an empty look, but don’t leave valuables or electronic equipment where burglars can see them through windows.
  • Never leave an answering machine message indicating you’re not home. Simply say that you cannot take the call at that moment.
  • Never leave door keys under a doormat or plant pot outside.
  • If you have a monitored home security system, make sure it is working properly and has been properly tested at least 4 weeks before you go away. If you do not have a monitored alarm, consider having one installed because they are an effective deterrent.
  • Use timer switches to turn lights on and off, giving your home the impression it is occupied. They are inexpensive, easy to operate and can be obtained from good DIY stores.
  • If you have a Neighbourhood Watch in your area, let them know your plans so that they can help keep an eye on your property.
  • Remember to cancel deliveries such as milk or newspapers. Uncollected mail acts as a signal that a house is not occupied.
  • Avoid discussing holiday plans with strangers, you never know who they might pass the information on to.
  • Secure important documents and valuable items in a safe place within your home or deposit them in a bank.
  • Put your home address on a piece of paper inside your suitcase and not visible on the outside. If you are flying, don´t put the labels on your luggage until you get to the airport check-in.
