Good security is vital! You’ll probably have many questions when it comes to making a perimeter fencing security decision. There are many aspects to electric fencing and our dedicated team have all the answers. Some common questions are listed below, however, if you still have queries please give us a call.
Q: What sort of a deterrent is it? A: An excellent deterrent. It is designed to keep unwanted people outside. Should it be cut, unlike razor wire for example an alarm will sound.
Q: Can a criminal place something like a blanket or rubber mat on top of it climb over? A: Due to the fence design using springs the wire will be shorted out when touching.
Q: Is it possible to connect the fence to my armed response company? A: Yes, most electric fences are connected to a armed response company.
Q: What would happen if the wires were cut? A: Firstly it would be difficult to cut the live wire without been shocked and if this did happen the fence would immediately go to alarm when wired in series.
Q: What sort of voltage is in the fence? A: The maximum voltage allowed by law is 10,000 volts. However it is the capacity of the energizer that gives the shock. The capacity is measured in joules not volts.
Q: Will my monthly electricity account increase dramatically? A: No, an energizer uses very little power, for the average house it could be less than twenty rand per month.
Q: Do tree branches have an effect on the fence? A: It is advisable to keep these trimmed back; however a good energizer is not adversely affected.
Q: Can gates be protected? A: Yes, all forms of security opening, sliding and power gates can be fully protected with the Electric Fence system.
Q: Do I only switch on the fence when I go out, or at night time? A: No, the fence is to remain on day and night every day of the year.
Q: What maintenance is required? A: Recommend – three routine maintenance inspections per year to ensure optimum system performance and reliability.
Q: What happens should there be a power failure? A: All Electric Fence systems have standby power supplies. In the event of mains failure rechargeable batteries power the system for a minimum of 4 hours. If a longer period is required the size of the standby power supplies can be increased.
Q: Is it necessary to connect to a rapid response company? A: An Electric Fence in it's standard form can be installed as a Stand alone system or directly interfaced with any other type of intruder alarm, access control or integrated security system. This is for all functions including arming, disarming, alarm monitoring and signalling. It is not compulsory; however there is a distinct advantage in doing so.
Q: What is the danger in electricity for people and animals? A: When electric current flows through an animal or a person it can cause the nervous system to react in pain, or by involuntary muscle contraction. These effects are temporary while other effects such as burns (at the points of contact and internal) and ventricular fibrillation can be life threatening. Ventricular fibrillation is the effect that occurs at the lowest level of current, this is where the heart becomes irreversibly uncoordinated and fails to pump blood, resulting in a fatality. The improper use of domestic electricity supplies and associated electrical appliances cause 1000's of deaths through this effect around the world each year.
Q: Will my cat/dog get hurt or electrocuted? A: Cats are perceptive to the aurora of the electric fence. That means they can smell the magnetic field and therefore would not normally be shocked by it. Dogs would usually touch the fence, but thereafter not continue to touch it; they will not die by merely touching it.
Q: So are electric fence energizers safe? A: Safety cannot be characterised in absolute terms, any product incorrectly used or applied can be hazardous. However, based on the safety records energizers are safer than almost any other manmade product in the marketplace.
Q: Are warning signs used? A: Warning signs are installed every 2 meters.
Q: What happens if someone touches an electric fence? A: It is difficult to find a recorded incident in which it can be shown beyond reasonable doubt that a correctly designed and operated impulse electric fence energiser has caused a fatality. Invariably when an incident occurs many other factors are involved. Secondary effects from a fence contact, someone falling, jerking back and hitting someone else, are likely worst case incidents associated with such a fence contact. It should be remembered that barbed or razor wire is significantly more hazardous due to the permanent physical damage possible with these products.
Q: What happens if children touch electric fences? A: Children can and do touch electric fences, they learn not to very quickly. It is a non-fatal learning experience. Should a child or for that matter an adult touch the fence the immediate reaction is to pull away.
Q: Will electric fences interfere with a heart pacemaker? A: This question is better specifically answered by the pacemaker manufacturer. But if the energizer is a threat at all, it is generally agreed that ventricular fibrillation will be the first fatal physiological reaction caused by the passage of electric current through the heart. As the primary function of the pacemaker is to keep the heart beating on a regular basis (that is prevent ventricular fibrillation) then the pacemaker could offer some additional protection. In fact a pacemaker operates with similar circuitry to a battery energizer, it is unlikely that the passage of impulse energizer current through the body and hence through the pacemaker would do any damage at all to a pacemaker.
