Gallagher Security: Safety, standards and smart deployment

Demystifying energised fencing in modern perimeter security, with Dave Solly, Product Manager, Gallagher Security.

Energized fencing still seems to carry a stigma in some circles. Why do you think that is? 

It really comes down to a lack of understanding. The term “energised fencing” can sound intimidating, especially to those outside the security industry or unfamiliar with the technology.

People often picture something dangerous or uncontrolled. In reality, these systems are highly regulated, rigorously tested and, when properly installed, extremely safe.

The problem isn’t the technology, it’s the misconceptions that surround it. 

So how safe is energised fencing, really? 

Very safe. Today’s energised fencing systems are built to comply with stringent international safety standards – such as IEC 60335-2-76 and multiple regional variants – that govern everything from voltage limits to pulse timing and installation and operational requirements.

These standards are specifically designed to ensure that the fence delivers a non-lethal, deterrent-level shock that’s safe for humans.

It’s comparable to an electric stock fence you’d find on a farm – but with far more robust design, monitoring and control. 

What’s changing in the energised fence landscape that security professionals need to know about? 

Several things. For one, following substantial changes to how energisers respond in the event of synchronisation lost on the fence, global installation standards such as BS1722-17 are in the process of being reviewed and updated to ensure enhanced safety practices are implemented.  

We’re also seeing evolving interpretations of these standards at national and regional levels that directly align with specific regional requirements; these changes can directly impact how systems are permitted and approved.

Whether you’re working in North America, Europe or Asia-Pacific, you need to be aware of how local codes map back to international standards. 

What’s your advice for teams trying to stay compliant? 

The best advice is to start with the standards. Make sure your system design, components and installation practices align with the latest versions of the standards I mentioned. From there, engage with local authorities early, especially when planning for permits or site approvals.

Compliance isn’t just about checking a box, it’s about being able to demonstrate that the system is safe, effective and designed with intent. 

Manufacturers of fence energisers are obligated to manufacture to the safety standards applicable in any particular region; where a regional variant does not exist, the IEC standards take precedence.

As part of the latest changes, manufacturers are now obligated to define what is a permitted installation scenario using their products – a good manufacturer will be able to guide you through that. 

Can you provide an example of where things have gone wrong – or right – based on understanding the standards? 

Absolutely. A correctly installed fence that’s within the manufacturers guidelines, uses products fit for purpose and is compliant to relevant standards, ultimately results in a system that whilst the energy delivered is extremely uncomfortable and memorable (which is required to make energised fencing work), it is safe, unlike some other deterrent technologies that are intentionally designed to physically harm a person. 

It is too scary to think about the consequences of fences (not just energised fences) installed poorly and outside side of the bounds of standards.

Manufacturers have a duty of care to ensure the systems they manufacture operate in the safest manner possible; equally they have a duty of care to ensure they provide the appropriate guidance to the installers, consultants, engineers and customers in the use of their products. 

Is energised fencing suitable for all types of sites? 

Not necessarily all, but it’s surprisingly versatile. High-security sites like data centres, utilities, logistics hubs and correctional facilities are obvious candidates.

But there is also significant adoption in commercial and even some regions’ residential applications where perimeter protection needs to be visible, proactive and reliable.

What’s key is identifying the requirements and security level of each site then integrating it as part of a layered approach alongside intrusion detection, surveillance and, where applicable, access control. 

What’s your key message to professionals considering this technology? 

Don’t let outdated perceptions hold you back. Energised fencing isn’t risky, it’s misunderstood. You’ll be using detection and deterrent technology that is intentionally designed to be safe.

When deployed according to modern standards, it’s a safe, proven and highly effective part of a perimeter security strategy.

Understanding the regulations gives you the confidence to specify, install and defend these systems with authority. 

Any final takeaway for readers evaluating their perimeter security options? 

Energised fencing offers a strong deterrent with proven detection capabilities and a clear signal that your perimeter means business.

With the right knowledge and the right partners, you can deploy it safely, compliantly and with confidence.

It’s time we moved past the myths and started seeing energised fencing for what it is: a powerful tool in the modern security toolkit.
