Profile of Electrocoil 
Live blue wire is for demostration purposes. Galvanised wire will be supplied.

Electrocoil is designed to provide an intruder detection signal and if required can also provide a high 7000 Volt repulse shock,

• low cost
• simple to errect
• effective
• false alarm minimised

Schematic Diagram of Electrocoil
 

Conductor/alarm coil

• As intruder moves onto the outer coil (earth) they touch the inner coil (live) which activates an alarm (or if the intruder earths the inner live coil he sets-off the alarm)

• Optional Repulse Shock

  In addition to the alarm detection system, a high voltage (5-7000 Volt) current can be fed into the system which will give an intruder a non-lethal repulse shock (this is an optional feature of the energiser)

Energised wire

• This "live return" cable forms a circuit which is used to detect cutting of the barrier, it is fixed to the end of the inner live wire and is considered optional as the act of cutting is also likely to cause a short circuit which will activate the alarm

Razor wire

• The outer coil which is made of barbed tape concertina/razor wire provides a fierce physical deterrent (this also prevents access to the live inner coil by innocent people)

Energiser

• It is connected to a 220 Volt / 12 Volt charger transformer which supplies the power. It also includes a 2-day battery

Profile of Razor Wire

High tensile steel wire virtually impossible to cut with standard tools with razor sharp barbs at close intervals provides an awesome deterrent
