Security Electric Fence topping | Alarm aFence®
Available exclusively through Jacksons, Alarm-aFence® is a cost effective and reliable combined alarm and electric fence deterrent designed to provide a physical barrier that delivers a non-lethal electric shock and alerts any attempted intrusion. Often used to provide additional security and protection to the perimeter of many of the UK's key Critical National Infrastructure sites.
Alarm-aFence® can be attached to the top of most existing perimeter fences or walls and can also be used as a stand-alone fence within an existing perimeter, offering high visibility and increased security. Furthermore, the systems can be controlled and monitored on their own secure network or easily interfaced with a third party security alarm monitoring system, to further increase perimeter security. The systems are zoned in accordance to the site operational requirements or CCTV zone specification requirements for remote monitoring and alarm verification.
Conforms to BS EN 1722-17 - specification for electric security fences - design. installation and maintenance.
Complies with all current standards including IEC 60335-2-76.

What is the maximum distance between strain points to be compliant?
Electric security fencing wires should be installed with a maximum distance between strain points of 150m. Wires should be supported and tensioned to maintain the original structure of the fence. For CNI sites, the maximum zone length is generally around 50m.
How does a gate work with an electric security fence?
Gates in an electric security fencing system must be on their own zone and be able to be opened and closed without receiving the shock. The electric fence will be on a different zone to the gate.
Does an electric fence system need a battery back up?
A back up battery should be installed to ensure the fence style operates in the event of mains failure. The battery must be able to supply the fence for at least 8 hours.
When should an electric fence be serviced?
Electric fence systems should have scheduled maintenance at least twice a year, or more frequently if specified by the supplier.
Do warning signs need to be displayed for electric fencing?
Yes, warning signs must be placed in clear sight and must be readable from both the secure and non-secure areas. Warning signs must be placed at each entry and exit point, between each change in elevation or direction, and spacing between signs must not exceed 10m. They must comply with BS EN 60335-2-76:2005+A2, B.2.
