ATTENTION
To ensure the safety of people and possessions, it is important that you
read all the following instructions.
Incorrect installation or incorrect use of the product may cause
serious harm to people and / or property.

IMPORTANT
SAFETY INSTRUCTIONS
Warnings for the installer
CAREFULLY READ AND FOLLOW ALL INSTRUCTIONS before beginning to install
the product.
• All installation, repair, and service work to this product must be done by a suitably
qualified person
• Do not activate the CLAWS unless you can see them and can determine that the
CLAWS are clear of people, pets, vehicles or any obstructions.
• Nothing must be placed on or near the trench covers at any time.
• No one must be near the trench covers at any time. Always keep people and objects
away from the spikes’ area of travel
• Children should be supervised to ensure that they do not play with or around the
spikes and trench cover
• This device is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety
• Secure all easily-accessed CLAW controls in order to prevent unauthorised use
• Do not in any way modify the components of the automated system
• Do not install the equipment in an explosive atmosphere. The presence of flammable
gas or fumes is a serious danger to safety
• Before attempting any work on the system, cut electrical power and disconnect the
batteries
• The mains power supply of the automated system must be fitted with a double pole
switch with contact opening distance of 3mm or greater. Use of a 5A thermal breaker
is recommended
• Make sure that an earth leakage circuit breaker with a threshold of 30mA is fitted
upstream of the system
• Never short-circuit the battery and do not try to recharge the batteries with power
supply units other than that supplied with the product, or manufactured by

movement risks such as crushing, dragging and shearing
• It is recommended that at least one warning indicator light be fitted to every system
• Always fit a warning sign visibly to the inside and outside of the entrance and exit
• The installer must explain and demonstrate the manual operation of the system in
case of an emergency, and must hand the User Guide and Safety Instructions over to
the end user
• Explain these safety instructions to all persons authorised to use the system, and be
sure that they understand the hazards associated with the system
• Do not leave packing materials (plastic, polystyrene, etc.) within reach of children as
such materials are potential sources of danger
• Dispose of all waste products like packaging materials, worn-out batteries, etc.
according to local regulations
• Always check the obstruction detection system, and safety devices for correct
operation
• Neither Centurion Systems (Pty) Ltd, nor its subsidiaries, accepts any liability caused
by improper use of the product, or for use other than that for which the automated
system was intended
• This product was designed and built strictly for the use indicated in this
documentation. Any other use, not expressly indicated here, could compromise the
service life/operation of the product and/or be a source of danger
• Everything not expressly specified in these instructions is not permitted

ATTENTION
For the detection of vehicles, we recommend installing
Inductive Loop Detectors in preference to infrared beams. When
installing the Loop detectors, positioning is very important for the safety
of the vehicle
• X refers to the distance required between the loops and CLAWS for
free-exit
• Free-exit for uni-directional traffic, X must be greater than 500mm
from the CLAWS
• For bi-directional traffic, X must also be greater than 500mm from
the CLAWS

CLAWS

page 9 www.centsys.com
CLAWS barrier spikes are designed to enhance the security at the entrance to
high-volume sites. They provide a formidable deterrent to would-be criminals and due to
their robust construction they are very difficult to defeat.
Clever modular design allows the CLAWS to be ordered ex-stock and can be configured
into a variety of different lengths. The orientation of the spikes can also be easily
changed depending on the direction of the traffic flow. Their external limit switches allow
for safe operation of the system.
CLAWS are easy to install and use a standard SECTOR II controller and a standard
SECTOR II gearbox, saving you time and reducing your spares inventory.
They boast all-weather construction and have been designed to allow for all moving parts
to be removed easily for quick and easy maintenance.
CLAWS also provide onboard support for a traffic light interface, and the Independent
Drive CLAWS models have variable speed control and multiple Modes of Operation.
The CLAWS Direct Drive system utilises the SECTOR II traffic barrier’s drive mechanism.
It is available in both Flush Mount and Surface Mount variants.
The Flush Mount models are ideal for installations that require seamless access control
for smooth-flowing traffic, whereas the Surface Mount models are mounted above the
general surface of the roadway and create a traffic-calming bump for a safer access
control point.

This document describes the basic steps to follow when installing the surface-mountable
CLAWS Spikes driven directly from a SECTOR II Barrier by a “push -pull” linkage
system. The installation described in this document is a 2.5 meter installation. For other
installations, modules of 1.5 or 1.0 meters can be used to achieve different widths.
The installation of the CLAWS Spikes requires a minimum of two persons.
5.1. Installation Configurations
The surface-mountable CLAWS Spikes can be installed in four different configurations.
The configuration is dependent on two factors:
• Orientation of installation
• Direction of spike impact
FIGURE 2. RHS CONFIGURATION
FIGURE 3. LHS CONFIGURATION
5.1.1. Orientation of Installation
The orientation of installation is described as the side at which the drive linkage is
installed when approaching the CLAWS Spikes. In other words, when driving up to the
CLAWS Spikes, in the correct direction for traffic flow, and the drive is installed on the
right-hand side of the vehicle, it’s deemed a right-hand installation. And when driving up
to the CLAWS Spikes, in the correct direction for traffic flow, and the drive is installed on
the left-hand side of the vehicle, it’s deemed a left-hand installation.
5. Introduction
INTRODUCTIONSECTION 5

page 15 www.centsys.com
5.1.2. Spike Impact Direction
The CLAWS Spikes are designed to take a much larger or more frequent impact in one
direction. The spikes can be installed to face either towards oncoming traffic (similar) or
face towards traffic (opposing) trying to enter from the wrong direction or lane.
There are four types of typical installations. Refer to Section 5, Figures 2 and 3 to
determine if the installation is left- or right-hand orientated.
Secondly; pay attention to the spike impact direction:
• Similar direction of travel prevents vehicles from exiting whilst the boom pole is
still down (Normal direction of traffic)
• Opposing direction of travel prevents vehicles entering against the flow of traffic
whilst the boom pole is down

The grease nipples on the bearing housings must face up (Section 6, Figures 19
and 20). Take note of the orientation of the Linkage Frame, the Bearing Shaft
Assembly, and the Drive Linkage Arm (Section 6, Figure 20).

Once assembled with the long drive arm, the layout should look as shown in
Section 6, Figure 21.
1. The drive arm must point towards the longer side of the drive linkage assembly (1.5x)
2. The notch must be at the bottom of the shaft (6 o’clock)
3. The bolt head must face the bottom and the nut on top
4. The angle of the bolt and nut must be as shown (11 o’clock)
STEP 11
Replace the bearing housing bolts once everything is in the correct orientation.
Hand-tighten for the time being.
