Electric Fencing
Electro-Fence™
A non-lethal, pulsed electric fence that deters, detects and delays intruders at the perimeter line.
Overview
Electro-Fence™ is a high-security pulsed electric fence engineered to deter, detect and delay intruders before they reach your asset. A safe but unpleasant non-lethal pulse provides a powerful psychological and physical deterrent, while an integrated monitoring system raises the alarm the instant the fence is tampered with, cut or climbed.
Designed and manufactured in the UK, Electro-Fence™ can be deployed as a freestanding barrier or retrofitted to an existing fence line, making it a cost-effective upgrade for critical national infrastructure and high-value sites worldwide.
At the heart of every Electro-Fence™ installation is the Pulstar™ energiser range (EF-100 and EF-130 series) - generating the precise, energy-limited pulse that gives the fence its deterrent power while continuously monitoring every zone for cut, climb and short-circuit attacks.
Key Features
- Non-lethal high-voltage pulse, safe by design
- Detects cut, climb and short-circuit attack within the set range of pulses
- Zoned energizers for precise breach localisation
- Freestanding or retrofit to existing fence lines
- Alarms integrate with Multisys® or any system accepting dry relay contacts
- Low-voltage alarm mode: switch the 10 kV off and still receive fence alarms
- Backwards compatible: systems 10, 20 years old and older remain supported
- Tamper-evident high-tensile wire construction
- NPSA Assured
- Powered by Pulstar™ EF-100 / EF-130 series energisers
Applications
- Critical national infrastructure
- Substations & power generation
- Correctional facilities (NLEF)
- Data centres & high-value storage
- Defence & government estates

How It Works
Detect. Deter. Alert. Record.
01
Detect
Continuous monitoring of circuit integrity flags any cut, climb or short on the fence line.
02
Deter
A safe, non-lethal high-voltage pulse delivers a powerful physical and psychological deterrent.
03
Alert
Zoned energizers raise an instant alarm and pinpoint the exact breach location.
04
Record
Events are passed to Multisys®, your existing control system or any platform accepting dry relay contacts, exactly as your operation requires.

Electro-Fence™ questions, answered.
What is Electro-Fence?
Electro-Fence is a UK-manufactured, non-lethal pulsed electric security fence that deters, detects and delays intruders on the perimeter line. It can be installed as a freestanding barrier or retrofitted to an existing fence, and is driven by the Pulstar EF-100 and EF-130 series energisers, the High Security EF-122 and EF-132 units and the EF-138 bi-polar energiser.
Is Electro-Fence safe and legal?
Yes. Electro-Fence is a non-lethal electric fence whose energisers keep every pulse within the limits of BS EN IEC 60335-2-76: 9.9 kV no-load output, 2 to 5 joules of energy and one pulse every 1.2 seconds. Installations follow BS 1722-17:2017, the British Standard for electric security fences. Non-lethal electric fencing is legal for commercial and government use across the UK, the US and most of the world when installed to standard.
How does Electro-Fence detect an intruder?
The energiser monitors the electrical health of every zone on each pulse. A cut wire, a climbing intruder shorting strands together or a deliberate ground-out each produce a distinct signature and raise an immediate, zone-specific alarm. Each energiser drives one or two zones of up to 300 metres at a 3 metre fence height, and a low-voltage alarm mode keeps detection running with the high voltage switched off.
Can Electro-Fence be retrofitted to an existing fence or system?
Yes. Electro-Fence can be added to an existing fence line as well as built as a freestanding barrier, and APS energisers are compatible for retrofit with third-party non-lethal electric fence systems, so ageing installations can be modernised while reusing the wire array, enclosures and communications already on site.
What power supply does Electro-Fence need?
Energisers run from 110 to 240 V AC or from a 12 V DC battery and solar supply, drawing 8 watts on average and 20 watts at peak. An optional 7 Ah battery gives eight hours of backup, and the electronics sit in an IP65 GRP enclosure rated from -20°C to +75°C.
How do Electro-Fence alarms reach my control room?
Alarms are available as dry relay contacts, so they integrate with any security platform, or over RS485 to Multisys, the APS security management system, which presents each zone on a graphical site map and monitors fence voltage in real time.
