THE “STINGER” BS120 SECURITY FENCE ENERGISER.
This user friendly unit has been designed for ease of operation, reliability and Simple operation of the
controls.
A fully computer controlled and integrated perimeter protection system with multiple units is easy to
assemble.
The unit has the following features:
A novel alarm monitoring system (SA Patent No. 99/5728)capable of protecting up to 20 zones. An
alarm condition will occur if the fence live wire is either cut or short circuited during 3 consecutive
pulses in the same zone.
The HV monitor system ensures stable zone information with no drift due to temperature or
corrosion.
Zone programming is very simple.
Fence Voltage can be switched to ”Low Voltage” (800V) or ”High Voltage”(8500V)
A warning will be given if the fence voltage drops below a level of 3000V due to a system fault.
All controls are located on the remote control unit. Communication between this unit and the
energiser is via a RS485 data link (4 core comms cable), via an RF link or via fibre optic cable.
Multiple Remote Control Units can be connected to one BS120 unit, in which case any control unit can
be programmed to be the ”Master” control unit or a ”Slave” control unit. 
The remote control unit can address up to 13 energizers. If multiple energizers are selected,
synchronization can be automatically applied.

A UHF Transceiver with anti-collision facility can be supplied for bi-directional data
communication over distance s up to 4 km.
Windows 95/98/2000/NT/XP software is available to interface up to 125 
Energizers to a PC via a RS485 data cable, RF data transceivers, or fibre optic
cable.
Up to 125 Site maps can be stored. To enable security control of different sites by
one computer.
The output voltage of each energizer can be viewed at the LCD Panel and will also be
logged via the computer program.
The software allows for pulse synchronisation of multiple BS120 units.
The zones have to be series wired and must be series connected to each other.
The start and end points of the fence and the fence ground are the only
connections to the energizer. An additional feature is that the fence is powered from
both ends.
An auto-reset facility is available and can be enabled or disabled. The unit will
automatically try to reset an alarm after 3 minutes. If successful, the alarm was
apparently a nuisance alarm and no further action is required.

Earthing practice
The above picture indicates how earthing should be done. This
picture only shows the earthing required to protect the energizer
against lightning. General fence earthing depends on external
factors like ground conduction etc.
Zone length: The best results will be obtained it the difference in
zone resistance is not more than 50%

INSTALLATION TIPS:
The following tips will help to facilitate installation.
1 Using the best type of bobbins and strain insulators will result in a trouble
free installation. E.g. Stinger strain insulators and Stinger intermediate bobbins.
2 Using low resistance aluminum wire will result in effective shock delivery.
3 Grounding the fence at regular intervals results in high stability and better
shock delivery .
4 Early morning false alarms occur due to arcing. Check the fence currents
with the display unit in the Power mode. If the HV1 and HV2 values are
unstable, there is a weak point somewhere at the fence. (Cracked bobbin,
too short wire spacing at stays etc.).
5 Keep HT wires away from communication- and power cables.
6 Underground HT Cables should be mounted inside irrigation tubing/conduit.
7 If the distance between the fence and the location of the energizer is long,keep the
two HT wires separated by 200mm. Use braided bare copper for the ground wire,
burying it directly in the ground. This will ensure the best eathing possible.
If the distance between energizer and control unit is more than 10 meters, it is wise
to mount a copper braided cable together with the comms cable.Ground this copper
cable at both end points.
The following table shows the effect of the type of fence wire used in relation to
practically obtainable distances.

*The value L(1/2V) is that length of live wire, where half of the energizer output
voltage drops across the fence wire and the other half across a person touching
thewire at distance L(1/2V). (Equals to only 25% of the potential energy at the
energizer output. This value relates to any energizer being used. The
resistance of ahumanbody has been standardized at 500 Ohms.)
8 Fence monitor lights : Recommended maximum three per BS120 Energizer, as each
fence monitor light draws +-0,4J.

FENCE WIRING EXAMPLES
It is important to always loop the earth wires together at each zone
split.This will ensure maximum energy transfer.
For extremely long fences, or in situations where the fence
resistance becomes excessive high, wires can be connected
inparallel. It is in this case important that the parallel connections
are repeated at the end of each zone as shown above.
For more information please refer to “Stinger Specification for construction of
electric fencing” available on request.

Long fences can be operated with multiple energizers, provided these units are
synchronized.
Stinger has SABS approval for such a system. Each energizer can feed one live wire.
The advantage of this system is that no trenching, cabling or solar panels are required,
as all units are located inside the guard house.
An additional advantage is the fact that the fence is much more secure in case of one
of the energizers failing.
Fences with a total circumference of 10 Km have been wired according to this system.

OPERATING INSTRUCTIONS
Zone programming
Before starting, check the following fence conditions (with the HV wires
disconnected):
1. The DC resistance of the HV loop must be lower than 1200 Ohms.
2. The DC resistance between GND and the live wires must be higher than
100000 Ohms.
Programming
1. Switch the Energizer on to High Voltage Mode.
2. Press the “Program” button for 5 seconds. If the buzzer sounds, there is
a fence problem, which must be solved first. The problem may be a short
circuit or arcing.
3. Make a short circuit at zone split 1-2 (use the cable with crocodile clips),
the buzzer will sound, press the “Accept” button briefly.
4. Repeat step 3 until all zones have been programmed. After the last zone
press “Program” again to leave this routine. The remote control unit will
indicate the program status.
Remote Control Unit Connections
The standard connection cable can be extended to a length of a 100m.
This can be safely done if lightning in that area is not a problem.
Otherwise add a braided copper wire to the cable, which must be earthed at
both sides.
For longer distances the “Stinger” data radio should be used.
USE STINGER LIHGTNING DIVERTERS BETWEEN THE ENERGIZER GND CONNECTION AND THE
HV1 AND HV2 OUTPUTS.
USE A MAINS LIGHTNING PROTECTOR AT THE MAINS INPUT TO THE UNIT.

THE FOLLOWING FAULTS CAN BE DISPLAYED:
The system is in the HIGH voltage mode and has detected that the live wire has been cut,
resulting in an open circuit indication. Pressing “reset” will silence the built-in buzzer, but the
problem needs to be resolved first before the screen will return to normal.
The system is in the LOW voltage mode and has detected that the live wire has been cut,
resulting in an open circuit indication. Pressing “reset” will silence the built-in buzzer, but the
problem needs to be resolved first before the screen will return to normal.
The systemis in the HIGH voltage mode and has detected that the livewire is touching a ground
wire in zone 2, resulting in a short circuit indication. Pressing “reset” will silence the built-in
buzzer, but the problem needs to be resolved first before the screen will return to normal.
The systemis in the LOW voltage mode and has detected that thelivewire is touching a ground
wire in zone 2, resulting in a short circuit indication. Pressing “reset” will silence the built-in
