Loops

Safety Vehicle Detector Loop

Safety Vehicle detector loops cut into the road surface to detect vehicles. These will prevent the equipment from closing/lowering on a vehicle within the aperture.

Quadrupole Loops

A quadrupole loops is actually two loops wired in a figure-8 pattern side-by-side, in series with a single wire. The name Quadrulope comes from the sensor having four poles (each loop has two magnetic poles). The two poles are wound in opposite directions, such that whenever the magnetic North is point up out of one loop, it is pointing down into the adjacent loop. This creates a tight channelisation of magnetic flux from one loop over into the other, resuting in maximum sensitivity over the centre of the sensor footprint with much less spillover around the sides. Also, note that the centre sawcut in the loop, which runs parallel to the direction of vehicle travel, has twice as many conductors in it as the edge sawcuts, and the current runs in the same direction for all of the centre-sawcut conductors. This makes the centre sawcut the most sensitive place over which to position motorcycle wheels. The quadrulope loop offers at least four significant advantages over standard loops:

  • Improved sensitivity
  • Lower false positive detections
  • A larger "sweet spot" over the centre wires
  • More logical placement of the "sweet spot" (in the centre of the lane)

A small quadrulope loop at high sensitivity can usually detect a motorcycle anywhere over the loop, not just over the centre wires. However, detection of a motorcycle does requires that the detector circuit to be set to a more sensitive. It is also recommended that markings be placed in the roadway to identify the centre of the loop to motorocyclists.

Signage

Warning and information signs are recommended to be installed with all automatic equipment to advise users of its operation

Traffic Light System

Traffic Light systems are highly recommended to be installed with all road blocker and bollard systems to advise all users of its position. 100mm traffic light head can be pole or mounted on control cabinet

Traffic Light Cage

Vandal resistant traffic light cages

Accumulator

In the event of a power failure or sabotage, the accumulator can raise and lower the blocker/bollard for a number of predetermined operations. An accumulator is a self contained charged unit with battery backed control system.

Extra Fast Operation

Increases the products speed of operation to a few seconds. Dependent on configuration. Please contact Technical Sales for more information on 01293 422800

High Security Cabinet

Special Security cabinets can be fitted and tested to BRE 1175 with 6 point security locking mechanism and fire resistance to DIN 4102. High security mauer key lock, Class A, ECBS/ENV 1300 approved, with similar rating to BS EN 1143-1 1997.

Security Rating 3 High Security Control Cabinet

Provides high security protection to the control cabinet of Frontier Pitts PAS 68 Anti Terra product range has been approved to Security Rating 2. Special Security cabinets can be fitted and tested to BRE 1175 with 6 point security locking mechanism and fire resistance to DIN 4102. High security mauer key lock, Class A, ECBS/ENV 1300 approved, with similar rating to BS EN 1143-1 1997.

Manual Hand Pump

In the event of a power failure, a hand pump/release can be provided to enable the manual raising and lowering of the blocker/bollard.

Hand drill to operate manual hand pump

Hand drill to operate manual hand pump on a Rising Terra Bollard or Terra Blocker.

Vehicle Detector Loops

Vehicle detector loops installed beneath the road surface to detect vehicles. This will prevent the automatic equipment from closing on a vehicle within the aperture. Safety induction loops cut into the road surface. This will prevent the gate from closing on a vehicle within the aperture.

Safety Photocells

Safety Photocells produce beams of light which cross the road way to monitor vehicle and pedestrian movement. If an object breaks this beam, the automatic equipment will stop & reverse. On gate installations, two pairs of photocells are usually fitted. Ultra Sonic Sensors are also available.

Flashing Beacon

Flashing Beacons provide a visual warning that the automatic equipment is in operation.

Sounder

Sounders/Audible Alarms provide an audible warning that the automatic equipment is in operation.

Terra Bollard painted finish

Active Terra Bollards are finished in stainless steel as standard. Alternatively, shotblasted and finished with a final coat of polyurethane paint is also available.

Stainless Steel Cabinet

As standard, the road blockers/bollards control cabinet is shotblasted and finish with a final coat of polyurethane paint.

However a Stainless Steel finish is also available as an option.
