The bollard system shall have (enter quantity) bollards operating together as a set. Each set of bollards shall have its own controls and operate independently of other systems under one of the following configurations:- A) Single Direction. Traffic flows in one direction only through the bollard system. B) Bi-Directional. Traffic flows in both directions through the same bollard. C) Twin Lane. Traffic flows in both directions through separate bollards where the entry and exit bollards are segregated by a traffic island. 2.2 Bollard Construction. The VP 50 is a hydraulically operated rising bollard assembly suitable for use in traffic management and anti-ram raid situations. The unit is designed to be easily installed by a competent technician. Installation A hole will be required in the road surface approximately 500mm by 500mm square and 1500mm deep. Provision should be made for connection to a suitable drain or,

4 alternatively, a soak-away should be created to ensure that the installation remains clear of standing water. The top 300mm depth of the hole must be opened out to 700mm diameter. To reduce water in the hole, pea shingle should be poured into the hole until its level is approximately 1215mm below finished ground level. Ducting is required from the unit to the control panel. Provision is made within the unit for the entry of a 50mm diameter duct. 2.3 Bollard Dimensions Bollard Height: Height of the bollard in the raised position shall be 800mm (31.5 ) as measured from ground level to the top of the inner bollard. Bollard Diameter: Diameter of the bollard is 101mm (4 ) Bollard Weight: 135kg 2.4 Hydraulic Pack & Circuit The bollard(s) either working individually or working in multiples shall be hydraulically driven through a hydra pack above ground and within the main control cabinet. The hydraulic pressure shall be adjustable and will pressurise a hydraulic accumulator if required. The hydraulic circuit shall include all necessary control logic, hydraulic hoses, quick release connectors and valves. Normal operation will allow the bollards to lower in the case of a power fail. In security applications the hydraulic circuit must be flexible enough to allow the bollards to remain in the raised position in power fail. This must be specified at the time of order. 2.5 Power Fail with Accumulator In the event of a failure with the power supply the accumulator shall allow one full cycle operations of a single bollard. 2.6 Manual Operation An optional hand pump can be supplied to allow the bollard(s) to be raised manually in the event of a prolonged power failure maintaining security. 3.0 Control & Logic Circuits 3.1 Control Circuit. A control circuit shall be provided to interface between the bollard(s), traffic indicator columns and the hydraulic pumps. This circuit shall contain all relays, timers and other devices necessary for all the operations of the system as defined. All control equipment shall be situated above ground and within the main control cabinet 3.2 Voltage The control circuit shall operate from a three phase & neutral power supply. 3.3 Control Cabinet The control panel shall be sufficient to house all the control circuits, hydraulic pump(s) and other devices for operation of the system that do not require external visibility (e.g. Radio Receiver) and shall be treated and finished in Black or Stainless Steel with a security level of either low, medium or high. The control panel shall have a side access panel for a manual override system and a mains power supply isolator. The control cabinet dimensions will be site specific dependant on number of bollards required. 3.4 Traffic Indicator Column(s)

5 The traffic indicator column is separate to the control cabinet and is strategically positioned to provide a Red or Green light to vehicle drivers alerting them to the bollard position. The green light shall indicate when it is safe to proceed. All other bollard positions shall cause the light to show red. External devices required for the operation of the system are housed on the traffic indicator column. Traffic Indicator Column Dimensions: 168mm diameter with a 45 sloping top x 2500mm overall length finished in Black or Stainless Steel. Specifying the Correct Number of Traffic Indicator Columns Operating Configuration Number of Traffic Indicator Columns Required Single Direction 1 Bi - Directional 2 Twin Lane 2 Repeater Traffic Light Columns may be Specified when necessary. Please contact the manufacturer for details. 3.5 Induction Loops Strategically positioned induction loops will allow the control system to detect a vehicle at all times and audit track the vehicle through the system. The number of induction loops required is dependant on the configuration of the system. 4.0 Safety Whilst the lowering of the bollard(s) by timer is permitted the raising of the bollards must not be carried by timer. This needs to be carried out in a safe manner. The system shall have an interlocking safety system and shall be Full Type Approved by the Highways Agency. The bollard system shall adhere to a risk assessment level 3 European directive. The requirements of a safety system to control this category of risk assessment are as follows (extract from section 7 of EN954-1). Safety devices and control systems as a minimum must be designed, selected and assembled to meet the operational requirements of design limits and influence of the process materials and other external influences. The complete safety control system shall be designed so that any single fault shall not lead to the loss of the safety function and, where practical, the single fault shall be detected. This now calls for not only redundancy in the interface but also in the input devices, pointing to dual channel systems. 5.0 Peripheral Control Equipment

6 5.1 Emergency Fast Operation (EFO). A hydraulic circuit consisting of a pressure reserve, interconnecting lines and valves can be supplied as an option. This circuit shall provide an available source of power to deploy the bollard(s) in an emergency and at speed even in the event of power failure. The final specification of devices required to operate the system will be discussed and issued at a later date but may include devices such as OMU, Transponder/Tag, Proximity Card, Radio Transmitter, Key Pad, Intercom, Vehicle Number Plate Recognition. This list is by no means exhaustive and the system shall be flexible enough to incorporate such devices. 6.0 Performance 6.1 Experience The bollard system shall be the type supplied and installed at major infrastructure sites globally. The manufacturer shall have at least 10 similar systems installed and in operation internationally with documented logs of all major components and design features. The Manufacture has 25 years developing and installing Manual Bollards. 6.2 Speed of Operation Normal speed of operation shall be capable of raising or lowering the bollards is approximately 10 seconds up and 10 seconds down. 6.3 Frequency of Operation The bollard shall be capable of 200 up/down cycles per day maximum. 7.0 Environment Data The bollard system shall operate satisfactorily under the following environmental conditions: 7.1 Extremes in Temperature The bollard system shall operate between the following temperatures. Normal Operating Temp for Control System: Maximum Operating Temp for Hydraulic Oil: Minimum Operating Temp for Hydraulic Oil: 40 C to -15 C 90 C - 54 C 7.2 Rainfall It is recommended the bollard outer casings are connected to a drain, if this is not practical then a natural soak away should be constructed. It is imperative to note that a natural soak away should only be considered if connection to a drain is not practical, the success of a natural soak away will be dependant on the ground conditions. 8.0 Quality Assurance
