Delta force
Delta Scientific has supplied the United States Air Force with an order of 541 Delta DSC501 barriers. In the largest contract for barricades ever, according to Delta, the USAF has deployed the K-54 certified high security barriers at facilities around the globe.
Set in a foundation 18-inches deep, the Delta DSC501 will survive and operate after a 5.4 million foot pound impact. “That’s equivalent to a 65,000 pound (29,484kg) truck hitting it at 50mph (80kph),” Delta says. “Stopping the truck dead in its tracks, the DSC501 protects against a ‘second hit’ risk from a second vehicle.”
When a car travelling at 60mph is detected within 90 feet, the DSC501 raises in just one second, time for the barricade to provide protection. In the lowered position, the DSC501’s barrier ramp is completely flush with the roadway. It is raised and lowered to and from the guard position via hydraulic cylinders, and the unit can be configured to operate one or more DSC501 barriers.

Underneath the radar
Navtech Radar’s W800 Automatic Surveillance system will be installed at Heathrow Airport to provide continuous automatic surveillance of areas on the airport’s perimeter. Touchstone Electronics will install the system.
The Navtech W800 is a new system in which a high frequency all weather radar, scanning in 360 degrees, automatically controls CCTV to identify and track intruders for perimeter and wide area protection. The contract follows a successful four-month trial of the Navtech Radar system at Gatwick airport at the end of last year.
Navtech says the W800 is immune to climatic conditions such as rain, snow, fog, sunlight, heat, cold and darkness, and “provides unparalleled levels of operational reliability and high quality surveillance data 24 hours a day”. It detects and tracks intruder movement up to 700m radius from the sensor, and can control as many as five PTZ cameras within a network configuration.
Compact design and undemanding power and communications requirements enable the unit to be used as a temporary or permanent fixture with minimal maintenance requirements.

Maid in Scotland
Jacksons Fine Fencing has installed fencing at one of Scotland’s most famous national heritage sites at Loch Lomond National Park, home to famous paddle steamer ‘The Maid of the Loch’.
The design and specification of the fencing was important as the end product had to be functional as a deterrent design, but also sensitive to the environment. The location originally had triple point palisade fencing, but it was felt that something more sympathetic and in keeping with a heritage site was required that was secure, to prevent any breach into the Maid of the Loch, and avert any potential vandalism.
The client chose the Barbican Imperial range with a polyester-coated green finish.
A double leaf gate with a raked base was added to the 1.8m high fencing to allow access to the site. The fencing had to be installed to accommodate the slope of the slipway and remain durable against the elements.

Covert sensors
OmniTrax is Senstar Stellar’s fifth generation covert outdoor perimeter security intrusion detection sensor field around buried sensor cables. If an intruder disturbs the field, an alarm is raised and the exact location of the intrusion is identified.
Targets are detected based on their conductivity, size and movement. Smaller targets, such as small animals, do not meet the minimum requirements and are ignored. OmniTrax operates through vegetation such as grass, bushes and trees.
OmniTrax’s digital processor filters out common alarms caused by environmental effects such as wind, rain, snow or blowing debris. As a result, OmniTrax has an extremely low False and Nuisance Alarm Rate, Senstar says, and maintains a high ‘Probability of Detection’.
“The terrain-following, volumetric detection field is typically 1m high by 3m wide by up to 400m long,” the company says. “Systems can be stand-alone or networked for long perimeters in which sensors are connected together to create a continuous perimeter. These cables also carry alarm information and low voltage power throughout the perimeter, saving installation time and money.
“Cables can provide bidirectional power and communications to provide full redundancy in the event that a cable is cut or damaged. The cables are robust enough for direct burial in most mediums. Once installed, the cables are completely covert, the field is difficult to detect and site aesthetics are left unchanged. Intruders cannot locate, avoid or tamper with the sensor.”

Stable cable
SabreFonic sensor cable is specifically designed to provide reliable early warning of intruders by detecting any attempt to cut or climb a perimeter fence. Manufacturer Remsdaq says the cable provides “a highly effective method of perimeter intrusion detection” and consists of a “continuously monitored and intrinsically safe, fibre optic sensor cable that is sensitive to a wide range of vibrations, flexing, compression and cutting”.
SabreFonic relies on the transmission of laser light as its detection method and so does not radiate signals, and is not susceptible to electrical interference. This makes it particularly suitable for use in hazardous industrial locations where there is risk of fire or explosion.
Remsdaq says its SabreFonic cable is easy to install and field repair, and replacement of a damaged section is straightforward, using a simple but effective splice connector. SabreFonic sensor is designed for use with Remsdaq’s Sabre II Perimeter Intrusion Detection System processor.
The company also produces the SabreLine buried sensor cable, for use in ‘sterile’ areas or over open ground where effective detection of intruders is essential. It is a pressure sensor, and Remsdaq says it is suitable for covert applications under grass, gravel or soil. It cannot be detected using metal detectors or other detection equipment.

Going underground
FAAC has unveiled its latest hybrid underground swing gate operator. The new S700 features hydraulic technology powered by a 24v motor and is designed to operate with both residential and light commercial gates up to 4m wide, with a maximum weight per leaf of 800kg.
There are four versions of the S700, with the option of two opening angles – 100 deg and 180 deg – both with or without hydraulic locking. Designed for continuous operation, safety is ensured with a built-in encoder. This allows the position of the gate to be monitored at the control board so that, in the event of obstacle detection, the gate stops and reverses a few degrees.
Simple fitting is facilitated by a robust steel foundation box that acts as the bottom hinge of the gate. It also has built-in stops for the open and closed positions. A new generation 32-bit control board has also been launched, offering a wide range of capabilities.
FAAC (UK) is a leader in the automation of residential and commercial gates and barriers. It has manufacturing and development facilities in Italy and Ireland and distributes its products in more than 90 countries.
