Deter, Detect, Delay.
A high voltage shock combined with a physical electric fence barrier will deter anyone from attempting to penetrate the perimeter fence.
The detecting ability and power of a SilverFox electric fence power by the trusted and proven Nemtek energizer will give an alarm when the perimeter of the property being protected has been infiltrated.
By keeping the perimeter protected using an electric fence, the attempted break in of the protected area is delayed, giving additional time for a reaction team to respond.
The prospect of a severe shock is as much a psychological barrier as a physical one. In addition tampering of the fence by shorting or cutting can be set up to activate an alarm.
The fence can also be connected via a radio transmitter or your burglar alarm system to an armed response company. The fence is usually powered by mains power with a back-up battery for use during power outages. We always ensure that the installation is as unobtrusive as possible whilst remaining effective.
TIPS TO INCREASE YOUR SECURITY
SilverFox world class products are designed and manufactured to ensure a high security solution and offer reliability for many years. Due to the large range of products on offer here are a few tips to ensure your system meets your security needs and operates reliably.
- Spacing between fence wires must not exceed 100mm. This will reduce attempts to part wires. Earth or live loops fitted on the fence will cause an alarm when there is an attempt to part the wire.
- The bottom fence wire where possible should be live and fitted with an antilif loop where there is a threat of lifting this bottom wire. The top wire must also be live.
- All electric fencing live wires must be connected in a series circuit so that a cut live wire can be detected anywhere along the fence.
- Spacing between posts must not exceed 3 metres. This will discourage attempts to part wires. In the case of freestanding fencing it is recommended that a shorter post be placed between the main posts reducing the span to 1.5m. This in-between shorter post will stop any attempts to lift the bottom wires. Ensure that the ground under the freestanding fencing is secure and not easy to dig under. The height of the freestanding fence must be at least 2m.
- The height of the bracket above the wall is important, the higher the wall brackets the more it discourages attempts to step over the fence. The wider walls will need higher and angled brackets to cover the span of the wall top and reduce any chance of standing on the wall.
- The fence wires must be under constant tension using compression springs. This will improve the aesthetics and the security of the fence.
- Alarm zones lengths should not be longer than 200 metres. The zones must be powered by independent energizer zones. This will help locate the fault faster. This is not always possible due to cost and location constraints. In high security areas shorter zones are recommended.
- No two zones must rely on each other being intact to operate effectively and must be independently alarm monitored. This is important in the case of an attempted multi-point entry breach of the fence.
- Gates can be a weak point. Make sure that sliding gates cannot be lifted up off the rack and be slid open. In the case of swing gates they can be forced open when they are closed. These gates can be monitored for unauthorised entry using a magnetic switch.
- Ensure that the fence is kept free of vegetation.
- Frequent testing of the fence is imperative. This test must be on a few points along the fence line.
