Electric fences are used as the first barrier of security in South Africa. It gives a shock as well as alarm when tampered with. If the electric fence is installed correctly, it will protect you in most instances from intruders.

Other security devices can be added as an extra. We can now enjoy the wonderful climate outside our homes without feeling unsafe. Keep in mind that an alarm system does not protect you when the doors are open and you are sitting outside.

Tandem Security Systems specializes in Corporate electric as well as Domestic electric fences. An intruder will find it extremely difficult to withstand the 9900 Volt shock to enter your premises. The shock from the energizer is non-lethal. It cannot seriously hurt or kill an animal or person if the system is installed correctly according to legislation. Apart from giving an intruder a nasty shock it is primarily an alarm system that can be monitored in different ways.

The electric fence can be controlled remotely from your cellular phone. We supply and install advanced CCTV and access control equipment and are able to integrate all our systems to provide clients with a turnkey solution.

Corporate land owners need to have a close look at legislation regarding the following:

  • There are certain rules that have to be taken into account when a fence is installed for example PUBLIC AREAS.
  • Peak voltage: – a High tension electric fence is where the peak voltage of a pulsed system exceeds 50V DC or AC.
  • Secure area is where a person is not separated from pulsed conductors below1.5m by a physical barrier.
  • Areas adjacent to such public areas, without a building element or some other method restricting access are also deemed to be public areas.
  • Electric fences nearer than 20 meters to a parking area also needs special attention. Live wires lower than 1.5m above ground level is not legal.
  • In other words, there must be a barrier fence below 1.5m or the bottom wires. Alternatively the bottom wires must be powered by a monitoring energizer with a low voltage output.
  • Tandem Security Systems offer an energizer that monitors the wires below 1.5m and has all the features of an electric fence without shocking anybody. If the fence is shorted or cut, the alarm will go off.
  • The latest version of SANS 10222-3: 2012 is available from South African Buro Of Standards. This is the legal document enforced by the OHS act.
