Lightweight Electric Fence System
Thank you for purchasing the Pentagon™ Electric Fence System. This is the first commercially
available electric mesh fence kit that meets or exceeds the guidelines published in the USDA
Forest Service Recreation Tech Tips (0723-2305MTDC) in March 2007. Please read the following
instructions carefully to become acquainted with the features, assembly, and safe operability of the
Pentagon™ Electric Fence. This high performance device must be installed and operated properly
in order to achieve the best possible results.
Counter Assault has assembled the highest quality components to provide the optimum perform-
ance, battery-operated, lightweight electric mesh fence system available. An electric fencing
system is comprised of three main components: (1) energizer, (2) transmission lines, in this case,
the mesh poly wire which includes the built in fence posts with insulators, and (3) the grounding
path to the earth.
How Does Power Fencing Work?
A pulsed electric current is sent along the fence wire from a
properly grounded energizer. When the bear touches the fence it completes the circuit between
the fence and the ground and receives a short, sharp but safe shock. The shock is sufficiently
memorable that the bear should never forget.
The energizer is the heart of the fencing system and Counter Assault has selected the Speedrite
AN90. The portable AN90 is operated by four "D" size batteries, which produces 35-45 pulses per
minute and delivers 8000-9000 volts, which equates to 0.12 joule output rating, with .16 joules of
stored energy, and can last for 30-40 days of continual operation.
Another unique component to this electrical system is the mesh fence. Tests have shown that the
mesh configuration with alternating hot (energized) and ground wires is recommended for bears.
The mesh containing the semi-rigid stays (the larger vertical poly wire) keep the mesh from
drooping, which could allow the hot wires to short out against the ground wires. Additionally, we
have incorporated ¾ inch sturdy double prong posts to keep the fence erect and reduce sagging.
The mesh fence is also quicker and easier to erect and disassemble.
