Electrostatic Field Sensor Basics • Parallel Sense & Field wires installed • Field Generator excites Field wires • Electric field coupled into Sense wires • Moving objects in the field change the coupling between Field and Sense wires • Processor detects a compound signal consisting of: • Amplitude Change (Mass of intruder) • Rate of Change (Movement of intruder) • Time Disturbance (Time intruder in pattern) • All Conditions are required to generate an alarm
XField - Features • Volumetric, terrain-following electric field disturbance sensor • 150 m (500 ft.) zones • Dual zone processor • Type 316 stainless steel sensor wire • Direct-to-digital signal processing techniques • Well defined coverage, adjustable detection pattern

XField Latest Developments - Hardware • Totally NEW Insulator Hardware • Common insulator assembly for the entire perimeter • Self-cleaning insulators, free of insects • Simplified wire tensioning procedure • More rugged mechanical design • NEW 316 stainless steel sensor wire • NEW Simplified splicing at the start and at the end of the zone • Simple resistor terminator • Factory-assembled lead-in cable 8 m (26 ft.) long • NEW simplified connection to the Processor • The Isolation Transformer (Sense Filter) has been eliminated. • Simple Phoenix terminals on the Processor Card for power and data • BNC coaxial connectors for the Field and Sense wires • All inputs and outputs have lightning protection • NEW Aluminum enclosure
XField Latest Developments - Firmware • NEW more powerful Digital Signal Processor uses a single FPGA (Field Programmable Gate Array) and high speed ADC (Analog to Digital Converter) technology • Direct-to-Digital front end • Part of a whole new family of perimeter security products • NEW full independent monitoring of each Sense Wire • Minimizes environmental effects • Distinguishes between faulty insulators and intruders • NEW lower Field Voltage and Frequency • Four operating frequencies (8000, 8320, 8640 & 8960) notch filters at both 50 Hz and 60 Hz to reject power line pickup • NEW Local and Remote Maintenance using the UCM software
XField Processor – Auxiliary Cards • Optional auxiliary cards enhance functionality: • Output card provides 8 Form C relay outputs (rated 1.0 A @ 30 VDC/VAC) in addition to the 4 relay outputs already present on the processor card. • RS422 Comm card supports two RS422 (4-wire) data lines, where a separate data network is required. • Fiber Optic Comm card supports two multimode fiber optic data lines, where a separate data network is required. • Auxiliary Power Supply accepts 18 to 56 VDC and provides 12 VDC, 150mA • NOTE: For networked data, every sensor processor must have a Comm card (RS422 or Fiber Optic). • The Comm Card does all data handling and regeneration.
XField Latest Developments – UCM Software • Laptop running UCM software is connected through a USB port directly to the XField Processor • All parameters are configured through UCM • Multiple maintenance and diagnostic tools • Reliable line supervision with diagnostic capabilities • When UCM is installed on the same computer as the Silver Network Manager, the UCM can be used to remotely configure, maintain and monitor any XField processor on the network.
