Detector and perimeter security product company OPTEX has launched its new fibre optic fence detection system, the Fiber SenSys FD508. It’s described as an eight-zone alarm processing unit (APU) – that uses algorithms to detect intruders who are attempting to climb over, crawl under or cut through a fence.
The APU is a rack-mounted design that can be a few kilometres from the fence. Features include a single-strand sensing design (that does not require a loop back) and up to 800 metres of sensing cable per zone. The makers say that it’s suited to critical infrastructure or large industrial premises. The firm says the fibre-optic sensing is unaffected by harsh external conditions including ultra-violet radiation, moisture, salt, or even lightning strikes. The algorithms are able to distinguish between genuine intruders and nuisance alarms that might be caused by wind, vibrations or small animals, it is claimed. The tuning software is included and comprises more than 30 parameters to tailor the system to its site.
Takuya Okamoto, Managing Director at Optex Europe, says: “The design has been modified to use standard connectors (SC/APC) and the configuration of the zones has been simplified by building the delay coils in, making this new model easier and more cost-effective to install.”
The high-end models within the Fiber SenSys range have been approved by the US Air Force and are the only fiber-optic intrusion detection system that is Protection Level 1 Nuclear (PL-1N) rated, and is the makers say suited for large government and critical infrastructure applications, including military (permanent and tactical), airports, government facilities, prisons, nuclear and chemical plants, refineries, heritage properties, power stations and reservoirs.
