Frequently Asked Questions About Electro-Fence™
Here are the most common questions we are asked about our electric security fence system. Essentially, they cover safety, cost, maintenance and installation issues. However, if you have a question that is not answered in this section, please let us know and we will be pleased to help.
How The Electric Fence Works & Cost
Q: What exactly is it?
A: Electro-Fence™ is an electrified fencing system which can be installed onto a new, or retro-fitted to an existing, security fence. It outputs a 1hz electrical pulse which is painful but non-lethal and complies with the relevant industry standards.
Q: How does it work?
A: Electro-Fence™ consists of wires that carry pulses of electric current to provide a non-lethal shock to deter potential intruders. Tampering with the fence also results in an alarm which is logged by the security electric fence energiser.
It can also trigger a siren, strobe or notifications to a control room or directly to the owner via email or ‘phone.
Q: Is Electro-Fence™ expensive to run?
A: No. Each electric fence controller uses less than 20 watts of power i.e. one-third of a 60w light bulb.
Electric Fence Safety
Q: Is it safe?
A: Yes, Electro-Fence™ puts out a non-lethal, but extremely painful pulsed voltage.
Q: Yes, but IS IT SAFE?
A: OK, here’s the detail. The pulses are limited to maximum 1 hz. That is designed to give you enough time to let go of the fence between heart beats. So, it won’t kill anyone, but it’s nevertheless quite painful. In accordance with industry guidelines, 2 joules is the most power which can go into a single pulse in the UK & Europe with 5 joules allowed in United States.
Q: What voltage is on the electric fence?
A: There is a maximum voltage of 10kv. This is pulsed once per second.
Q: What about animals?
A: A 10kv pulse is just as unpleasant to our animal friends as it is to humans. So, if they do get a shock, they are not likely to be back for a second.
There is a possibility that a small animal, such as a hedgehog, could get trapped in between the lines. So, we recommend making the bottom couple of wires earth lines so that such animals can get underneath.

Q: Can I have my trees and shrubs close to the electric fence?
A: Yes, but there should be at least 1 metre clearance from it (or any object) to the fence.
Electric Fence Installation
We can also give detailed instructions should you wish to use your own installer. If you wish, you can visit us and we will give the appropriate installation training.
Q: What height is the Electro-Fence™?
A: Electro-Fence™ should be behind a fence of at least 1.8m high and extend 600mm above it to stop climb over.
Q: Can I put Electro-Fence™ on top of a wall?
A: Yes you can, provided it is at least 1.8m from the ground.
Q: Can I have a free standing Electro-Fence™?
A: Yes, a free standing electric fence is the solution for many large outdoor sites.
Shipping terminals, water pumping stations and reservoirs are just a few examples of the type of site where this is an appropriate perimeter security solution.
Electric Fence Security Alarms
Q: What about security alarms?
A: Electro-Fence™ is capable of generating many types of alarm. It depends upon the configuration of electric security fence that you would like:
- Shock monitor and output an alarm after an intruder has been shocked a pre-set number of times.
- Voltage monitoring
- Cut monitoring
- Short circuit monitoring
- Earth wire cut
- Earth wire short to live
- Earth wire short to ground
Whilst the Electro-Fence™ range can output alarms as a contact closure via integrated dry relay contacts, our elegant Multisys™ software suite offers the end user the capacity for a fully centralized node system where RS485 linked energisers can be monitored real time on a Windows computer. It can also be integrated with complimentary security systems such as our Flexiguard™ perimeter detection or Microguard™ microwave intrusion system and CCTV cameras.
