    INTRODUCTION INTRODUCTION The FV300 FlameVision range is a new family of advanced, high technology infra-red array flame detectors with reliable wide area flame detection and excellent false alarm immunity. The FV300 FlameVision detectors offer a major improvement in both flame detection capability and immunity to false alarm sources over triple IR detectors.

  • Page 5: Principles Of Operation

    PRINCIPLES OF OPERATION PRINCIPLES OF OPERATION GENERAL In order to optimise the detection of flames from hydrocarbon, the FV300 detectors analyse radiant infrared energy at the peak carbon dioxide emission wavelength around 4.5µm. In a separate guard channel, the detectors also sense additional wavelengths between 4.8 and 5.8µm to determine whether the spectral content received possesses the signature of a real flame.
  • Page 6 PRINCIPLES OF OPERATION Fig. 3 Another advantage of array-based detection is that non-flame interferences, eg, black body or light sources, can be uniquely identified to within an area of the field of view. This ability to separately analyse signals from flame and non-flame sources enables array based flame detectors to not be desensitised in the presence of non-flame interferences, unless such sources are physically coincidental.
  • Page 7 PRINCIPLES OF OPERATION To ensure that flames from all potential fuels are detected whilst minimising the risk of nuisance alarms, an optimum spectral signature of a flame, defined by its ratio at the two measuring wavebands (A/B in Fig. 4) has been established experimentally by lighting characteristic fuels at different distances.
  • Page 8 PRINCIPLES OF OPERATION 2.3.3 IMMUNITY TO SOLAR RADIATION Modulated radiation from direct or reflected sunlight as well as modulated radiation from strong sources of artificial lighting can produce an unwanted response from infrared flame detectors. To counter this possibility, the FV300 detector looks for the flame in a very narrow waveband where most of the sun radiation is absorbed by CO gases in the atmosphere.

  • Page 9: Application

    APPLICATION APPLICATION GENERAL The FV300 FlameVision detectors are intended for the protection of high-risk areas in which accidental fires are likely to result in flaming combustion with the production of carbon dioxide. Typical materials in this type of risk are: a) Flammable liquids, including petroleum products, alcohol and glycol, etc.
  • Page 10 APPLICATION Summary of FV300 FlameVision features and benefits: Detection: The FV300 provides high sensitivity flame detection with high false alarm immunity, undiminished throughout a wide field of view. An infra-red array combined with 2 other optical sensors provides 3 sensitive optical channels.
  • Page 11 The FV300 FlameVision series are a whole new range of flame detectors developed from the knowledge and experience built up from previous detectors such as the S100 and S200 series. However, the FV300 series is not a complete replacement for the existing detectors and the following should be considered: The FV300 will only be available in Flameproof versions.

  • Page 27 SYSTEM DESIGN INFORMATION FALSE ALARM IMMUNITY The FV300 has been subjected to the following stimuli that might be considered potential sources of false alarms. Unless otherwise specified, tests were performed at a minimum distance between source and detector. Steady state sources were chopped at both regular and random frequencies in the range 0 - 10Hz.

  • Page 32 OPERATION ALARM SIGNALLING The FV300 detector has a number of external interfaces. An alarm condition is signalled on all of these interfaces as follows: Alarm relay: The alarm relay will close. 4-20mA: The current (source or sink) becomes 17mA Modbus: The alarm bit is set in the status register and is available at the next read of the unit.
  • Page 33 OPERATION FAULT AND OPM SIGNALLING The FV300 detector has a number of external interfaces. A fault condition is signalled on these interfaces as follows: Fault relay: The fault relay will open. (Hardware, window and OPM faults) 4-20mA: The current (source or sink) become 0mA for hardware and window faults or 2mA for OPM faults.
  • Page 34 OPERATION 5.10 RESETTING ALARM AND FAULT CONDITIONS In latching mode, alarms and faults will continue to be indicated and signalled, even if the original cause has been removed. The detector needs to be reset to clear the condition. The detector can be reset by activating the wired input or remotely using the walk-test trigger tool.
  • Page 35 OPERATION 5.13 WALK-TEST (ALARM TEST) WARNING: THE DETECTOR OUTPUTS WILL BE ACTIVATED DURING A WALK-TEST. DISCONNECT ALL EXTINGUISHING SYSTEMS OR EXTERNAL DEVICES THAT SHOULD NOT BE ACTIVATED DURING A TEST. The FV300 detector has a built in alarm test facility. The lamps used for the OPM test are flashed in a pattern to simulate a flame.

  • Page 36: Installation

    INSTALLATION INSTALLATION GENERAL The FV300 Series detectors may be surface mounted or may use the FV300 adjustable mounting bracket. On the FV311 series, all electrical connections are made via terminal blocks inside the detector rear housing. Two 20mm cable entries are provided. On the FV312 series, electrical connections are made through the FlameVision Exe junction box, selecting the appropriate circuits required.
  • Page 37 M6 studs with nuts and locking washers provided. The FV300 Series may be operated in any position but the mounting point must obviously be chosen to allow sufficient clearance for adjustment of the angle and must also allow space for the cable assembly.

  • Page 38: Detector Wiring

    INSTALLATION 6.2.3 MOUNTING THE FV312 SERIES DETECTOR WIRING In addition to the installation recommendations given in 6.2, the following applies when installing FV312 series detector: a) The detector in-built cable should interface with the field cable via an EExe junction box with EExe cable entry glands suitable for the size of cable used. The FlameVision EExe has been designed to provide a ready-made solution to interfacing with any of the inputs/outputs of the FV300 detector.
  • Page 39 INSTALLATION 6.3.2 RECOMMENDED CABLE TYPE 6.3.2.1 CONVENTIONAL CIRCUITS The cable selected for interconnection to the control equipment should meet the requirements of any national codes (eg, BS5839) or relevant approval bodies. Cables should not normally have a cross sectional area of less than 1mm for solid conductors or 0.5mm for stranded conductors.
  • Page 40 INSTALLATION The use of stopping plugs with a mushroom head and integral ‘O’ ring is recommended. The glands/stopping plugs should be hand-tightened with the addition of, at least, a further turn applied by spanner or other suitable tool. Where it is not practicable to use a nylon gland washer or where an anti-seizing union is required, the following alternative methods may be used: a) The thread of cable glands/stopping plugs may be sealed using PTFE tape or other jointing putty or mastic.

    COMMISSIONING COMMISSIONING SYSTEM CHECKS Before connecting the zone wiring to the control equipment or to the detectors, a general inspection of the system should be carried out. In particular, the positions of the detectors should be checked to ensure that the requirements given in the System Design and Installation sections are met. When the system wiring has been successfully tested and the control equipment commissioned, the detector electronic assemblies may be fitted.

  • Page 53 8.1.2 DETECTOR CLEANING The FV300 series detectors are relatively tolerant of accumulations of dirt on the sensor window or optical monitoring reflector (see Fig. 22). However, thick deposits of dirt and oil will cause a loss of sensitivity and a subsequent fault indication.

    MAINTENANCE 8.1.3 FAULT FINDING If the detector reports a fault, then the indicators along with the 4-20mA, video or network interfaces can be used to diagnose the cause. Refer to Section 5 ‘Operation’ for more details and Appendix B for information on video overlay messages. The most likely fault is a dirty or obscured window.
