GENERAL DESCRIPTION
When properly designed and installed, an electric security fence is the least expensive, safest, and most secure method for securing property and lives when compared to walls, other types of fences, human guards, and watchdogs. The fence does NOT sleep. The fence CANNOT be bribed. The fence does NOT require food or water. A well-designed electric fence has more deterrence value than a guard with a sawed off shotgun or a snarling pit bull.
The Security Fence is scientific fence and works on Energy with backup facility to run uninterruptedly during the nights as well as cloudy days. The whole system can be derived into two segments, one is the Basic system with CS 250 Unit (Without keypad) and the other one is the Fence.
CS 250 Unit takes 12V supply as input and energizes the same into high volt pulses in the range of about 7000 Volts. These pulses will travel through the fencing wires at regular interval of 1.2 second and the duration of each pulse will be 0.03 seconds.
The fence part is a scientific type of layout in which multi strands at 4 inches gap will run through the insulators, which are pre-fixed to MS galvanized posts. The height of the fence above the compound wall will be 4 feet. The posts are arranged at 3 meter gaps with perfect supporting to the corner poles. Proper earthing in the mode of Super Earth Kits which is a composite Mixture of different minerals helps the fence to have a perfect earthing system as solar fencing requires good earthing for effective working.
There is a provision for restricting the intrusion through the gate as well as over the gate (Optional). The spring loaded barricades arranged to the gate will electrify the gate and activates the alarm when somebody tries to open the gate forcibly. Pulses travels through the springs arranged on the gate and give the shock to the trespassers / intruder.

DESCRIPTION OF SECURITY FENCING AND ITS WORKING GENERAL
Security Fencing is the modern day’s alternative to the conventional type of perimeter protection. These are active fences and punish the unwelcome intruder the moment they touches the fence or try to tamper the fence. The conventional types of fences are only passive fences and cannot resist the intruder if they try to forcibly intrude into the protected area. The Security Fence gives a sharp, short but a safe shock and creates psychological fear. Against any tampering the alarm incorporated in the system gets activated and alerts the inmates of the protected area, which facilitates them to counter the unwelcome intruders.
If you have security guards, you can pay for and justify the fence by reducing at least half of your guard force and still maintain a much higher security level. The remaining guards can respond quickly before an intruder even enters onto the property. You will find that an electric fence is the best security investment that you have ever made.
An Electric Security Fence is designed to keep out predators, thieves, trespassers, vandals and disease. If you also employ security guards, they will complement the security that is provided by a well-designed high voltage electric fence.
An Electric Security Fence is designed to protect property, livestock, production, manufacturing, and lives. Every situation is different, but there are also some considerations that are the same, no matter who, what, or where. The components of the system shall be installed and mounted inside a metallic enclosure and very near to the fence and LOCKED out of reach from unauthorized people.
We recommend that you check your fence at least once a week. Plant foliage, or branches or fronds laying across the high tensile wire might not reduce the voltage on the meter when dry, but foliage becomes a conductor when wet and might easily short out your system completely reducing the fence voltage to almost zero when soaked from rain.
TECHNICAL DETAILS
- The system will be a Non-Lethal Security system.
- The system will operate as a Psychological and physical Barrier.
- The system will alert any kind of intrusion through an audio alarm System that can be in the vicinity of more than 300 meters, within a second.
- The security fence system will produce a high voltage at an energy output of 2.5 Joules, which will act as an active deterrent, a physical barrier and a reliable detection system.
- The security fence system produces a high voltage in the range of 6.0 kV to 9.9 kV (No load) to deter, detect and deny physical intrusion by giving the intruder a short, sharp and painful shock.
- The Energizer will be able to check the fence around 50 times a minute and the instant the pulsated wires are cut or tampered, a built-in-alarm will immediately alert the monitoring personnel and the security authorities, along with the zone of attempted break-in (Optional).
- External Alarm will be activated within a second. As a precautionary means an internal alarm is provided as a substitute in case of failure of external alarm.
- The Lead Acid Battery (Reputed Make) along with electronic system will be concealed in a Metal box. A Live light fixed on the fence will indicate the activeness of the power fence system.
- Auxiliary supply of 230V AC to be provided by the Customer.
