Electric fencing is one of the most cost effective, electronic perimeter breach deterrent & detection systems.
The advantages offered by electric fencing are:
Electric fencing offers a physical as well as a psychological barrier
Maintenance is very low as brackets and relevant components of the system are galvanised, all wiring, nuts, bolts, springs, strainers and fasteners are 314/316 grade Stainless Steel
Optional powder coating offers additional anti corrosion protection {All the above attain to Retrospective Trading and are not necessarily the industry standard}
When commissioning and installing electric fencing for domestic or commercial properties we only use 316 grade stainless steel wire, strainers, springs and fittings, all uprights are hot-dipped Galvanised to SABS ISO 14621OF2000 standards, this standard is ideal for costal installations and use, and powder coated if needed.
Retrospective Trading offer an unconditional 24-month guarantee, on all new commercial or domestic electric fence installations.
How Electric Fencing works
The system works by sending a high-voltage electrical pulse around a multi-wire perimeter fence, the potential involved may be on the order of 2,500 to 12,000 volts, the current is limited to a safe level and the actual pulse lasts only milliseconds.
The source of the high-voltage electrical pulse is an electric fence "energiser"
When an individual trying to breach the fence, comes into contact with the fence by climbing over/under, the "Live" fence will become part of an electrical circuit between the output terminals of an energiser, a high voltage pulse will flow through the body of the individual to the closest earth, leaving the perpetrator temporarily incapacitated.
The strength of the shock depends upon the power available from the energiser, and the total resistance of the circuit.
Electric Fencing not only offers effective protection but also a psychological deterrent, if the fence wires are deflected by vertical movement, contacting strands either side or cutting the strands, the system will cause a short circuit on the fence line, and trigger the alarm, giving an audible and visual indication of a fence breach.
The fence controller is a monitored alarm system; the fences can be zoned for easier detection of breaching.
False alarms are virtually non-existent, as the fence will only go into alarm when a concerted effort is made to break the perimeter security.
Our existing clients have reported the system as paying for itself within twelve months of installation.
To date this system has proven to be a very reliable and highly effective security system. In sites previously subjected to a number of attacks the system has eliminated all losses and in some cases removed the need for a resident security guard.
The system is capable of protecting and controlling anywhere from one to 100+ zones each of 50-150 meters in distance. This provides a very flexible solution for most requirements.
