WHAT IS AN ELECTRIC FENCE AND HOW DOES IT WORK?
An electric fence was primarily developed for the restriction of animal movement. Since this time the security industry used the initial technology and improved on it to give a system utilizing wires fitted on insulators and powered by an energizer which is capable of developing a substantial and most uncomfortable shock.
The professionally made energizers conform to strict legislation and must comply with such governing bodies as the government and SABS. This legislation has been introduced to stop the public from being fatally shocked. The maximum voltage allowed in South Africa is 10 000V. There are also other controlling legislation such as the minimum permissible height, warning signs and earth conductors.
ADVANTAGES OF AN ELECTRIC FENCE:
There are three main advantages of an electric fence installation:
- The visual protective appearance / this also acts as a psychological barrier - if you install a good electric fence the visual appearance will be a definite deterrent. The psychological aspect is that you feel much safer once it has been installed.
- The shock capacity - When correctly wired and the right size energizer installed, the shock experienced will be of such a magnitude that it would deter a person from trying to enter the premises.
- The alarm given - It places an 24 hour monitor on the perimeter. If wired correctly the electric fence will go to an alarm when the wires are cut or shorted.
The electric fence can be linked to your existing security service rapid response provider.
