LHD – FiberSystem 8000 PFS Series Fibre Optic Cable

LHD fibre optic cable technology in fire detection is ideally suited to industrial high-risk hazards and many types of commercial applications. Protectowire’s PFS Series Fibre Optic Sensor Cable has unique advantages over other types of detectors, especially when difficult installation factors or severe environmental conditions are present.

The PFS Series product range consists of two distinct types of Sensor Cable. Each type has a unique construction that has been designed to accommodate the widest range of installation requirements and environments.

FEATURES

• Two distinct cable options
  • Metal-free – Most commonly used where there is a high amount of electromagnetic interference (EMI) or radio frequency interference (RFI), eg. Tunnels, Cable Trays & Transformers
  • Stainless Steel Core (Fully reinforced) – Used in most industrial environments, eg. Storage Warehouses, Conveyors & Pipelines
• Immune to electromagnetic interferences
• Withstands severe environmental conditions
• Little or no maintenance required
• Halogen-free, flame-retardant jacket
• Programmable alarm temperature
• Fully reinforced and metal-free

FR Sensor Cable (PW-PFS-554FR) consists of a stainless steel core tube containing two independent colour-coded quartz fibres, each with an outside diameter of .25 mm. The tube cavity is gel-free and longitudinally and laterally watertight. The outside of the core tube is wrapped with a layer of fine stainless steel wires that add to the cable’s mechanical and tensile strength. The sensor cable is then sheathed with a halogen-free, flame-retardant FRNC thermoplastic jacket suitable for a wide range of applications and environments.

MF Sensor Cable (PW-PFS-654MF) is a metal-free sensor specifically designed for use in applications where a high amount of electromagnetic disturbances are expected, like tunnels, high voltage cable trays and transformers. To minimize the risk of induced voltages, the construction of the metal-free Sensor Cable substitutes a polyamide core tube reinforced with Aramid yarn in place of the stainless steel tube and wire used in the FR-type Sensor. The outer jacket consists of the same halogen-free, flame-retardant FRNC thermoplastic used throughout the product line. This series is best described as multi-purpose, and is well suited to a wide range of both commercial and industrial applications.
