1. Dissuasion: This is one of the most important components. The system is easily seen; it is not hidden or disguised. Its presence is evident, as is the warning that it will produce a painfull though not lethal, electric discharge if someone tries to go through it. It alerts and punishes with a non lethal electric shock. 2. Detection: Different from other non-reactive systems, any attempt of intrusion or manipulation will set off an alarm signal. One single electric pulse lost will not set the alarm. Continous lost electric shocks not returning to the energizer will. 3. Effectiveness: Simplicity of use is the basis for its strength. Works 24/7 year round. 4. Maintenance: Part of the simplicity and efficiency of a system is directly linked to its maintenance. The most common care it requires is keeping it free of vegetation and checking its voltage and line tension periodically. 5. Aesthetics: The perimeter protection system is very low profile and its visual impact very little. It is visually adjustable so that it minimizes visual impact and combines with any type of fence or wall top. The use of the appropriate colours helps to mingle it with the surrounding. 6. What effect does the discharge have on human beings? When trying to penetrate it, the system will give the intruder a non-lethal electric shock that will cause permanent damage. The system works based on pulses (not continuous current) and with very low amperage. 7. The fence’s location - at wall tops or behind cyclone-like fences - considerably reduces the possibility of children or non-intruders touching it. However, if this were to happen, the effect is not lethal. 8. Easy to integrate: The system is can easily integrate with other existing alarm or detection systems. 9. Flexible: An Electric Fence is extremely flexible and adaptable to fit any perimeter profile wished to be protected. 10. Registration: If the system is connected to a remote monitoring central with an “events” software, these will be registered including date, time, and – if it is a zoned perimeter – it will identify the exact spot where the intrusion attempt is taking place. 11. Cost: The cost of an Enérgico® electric fence depends on two aspects: the cost of the linear meter and the cost of the energizer.

What is an electric fence?
An Electric Fence is a complete alarm system with the additional deterrent feature, of being capable of inducing a no lethal,high voltage shock to illegal intruders. The energizer that powers the system produces a high voltage pulse (6000 to 10000 volts) with very low amperage (where lays the potential danger to the human body).

The energizer has a back up battery that maintains the system running even when the main 110 volts source is cut.

The back up rechargabe battery can support the system for about 48 hours or more unless the alarm is continuously active, since the sirene feeds from the back up battery, it drains it very quickly if the alarm is constantly on. In the event of an emergency when main power will not be available for longer periods, a high amperage battery normally used on automobiles, can maintain the system running for longer periods since the energizer`s power consumption is very low.

The ideal voltage on the fence is between 7000 to 8000 volts. A System running 15 thousand volts is not better for having a higher voltage. The non lethal pain it inflicts on the intruder is the same at 7000 thousand volts as it is at 15 thousand. On the other hand, the higher the voltage the more sparks the system will produce with the potential risk of setting a false alarm . Good grounding of the system is pivotal for its correct operation, protects the energizer and assures a good quality electric shock on the intruder.

What affects the electric shock effect on the intruder?

• The humidity on the ground on which the intruder walks at the moment it contacts the electric fence.
• The thickness and quality of the shoe`s. More insulation, less pain.
• The body mass. More body mass, more effect.
• From 5000 volts and up, with properly done grounding, the effect on an intruder is the same as 12.000 volts. (this varies depending on the previous parameters).

How does it work?
When the intruder touches the wires (not all of them are live) the body receives a painful no lethal electric pulse (not continous current)

False Alarms
False alarms are almost inexistent. The system requires the setting off of three pulses –or more- to turn on; this way, if a cat or another animal touches the Electric Fence® this will not trigger the alarm given that only one pulse would have been lost.

Technical Features
Energizer: It is the equipment that provides energy to the system: It comes within a metallic o plastic box that generally is installed somewhere near the protected perimeter , keeping it away from the reach of children usually in a waste room, laundry room, security booth, etc…

Grounding: A good grounding is essential for the proper functioning of the Electric Fence®. This is made either with a copper or galvanized bar, depending on the equipment specifications. Two bars is the standard but in large perimeters more grounding is needed sometimes.

Lines: The wiring of the fences alternates positive and negative.. Low voltage is used to wire zoning cards (not all energizer models have this capability, please check) if the perimeter size or security conditions, requires it. The number of lines (seen vertically) may vary from a minimum of 2 to up to 26 or 30 lines.

How to keep tension in the lines
Enérgico S.A. uses Gripple® for wire tensioning (www.gripple.com.uk) , a very ingenious device that keep lines tense, also used to fix any ruptures and assure that the Electric Fence wire is tense at all times, “like a guitar`s string ”.

Bridges
Connections between two sections of the fence when there is a level change or an increase or decrease of the number of lines .

Output and Return
The energizer sends the high voltage pulse to the fence, it goes around the perimeter and return from the fence to the energizer. Some of these systems have a microchip that “learns” what the normal conditions of each installation are, a minimum – but normal – variation may not activate the alarm . But a sudden loss of three pulses trigger it (three seconds of electric flow interruption). Similar systems defend Israel’s border with its neighbor countries. This way an intrusion can be detected as well as manipulation attempts. Some models admits being zoned, (justified only for big perimeters) monitoring both high lines as well as the neutral lines. Other models can be programmed using a keyboard to select voltage level and time of activation , only alarm mode or alarm + high voltage mode.
