Comparisons
     Flame Detectors - Old Technology
     Ultraviolet Only (UV) (0.18 to 0.26 microns)

   Highly false alarm prone to arcs, corona discharges,
    welding, halogen lights, sparks, etc.

   Easily blinded by contaminants on lens such as oil film,
    paint, powder, chemicals, smoke, suppressants,etc.
      Flame Detectors - Old Technology
        Single band Infrared (IR) (4.3 micron)
   False alarm prone to heat sources, lights, ovens, etc.
   Slow response to “fireball” type fires.
   Relies on unpredictable CO2 narrow band emission line
      Flame Detectors - Old Technology
                               UV/IR
   Far less false alarm prone than UV only or single band IR
    flame detectors.
   However, doubles reliable and positive detection problems
    since both UV and narrow 4.3 micron band IR channels
    must trigger in on order to alarm to a fire. If one channel is
    blinded, no alarm.
   Unreliable - UV tube and UV self-test source prone to failure.
    Flame Detectors - Old Technology
         Dual Frequency IR/IR (4.3 micron
        with 3.8 micron background reference)
   Slow response to paint spray fireball type fires
    because of narrow band 4.3 micron signal.
   Blinded by contaminants because of narrow bands.
   No self-test to determine if sensors are blinded.
   Bulky housing and obsolete analog technology.
   No re-flash fire detection if cold CO2 used as
     suppression - absorbs hot CO2 IR from a fire.
     Need for a More Reliable Flame Detector

   Flame detector must have two stages of response:
    1st Stage - shutdown the spray guns
    2nd Stage - signal for suppression release.
   Must detect both fireball and a flickering non-fireball fire
   Has to detect all types of burning materials including solvent-
    based paints, waterborne paints, powder paints and alcohol
    for cleaning.
   Must be able to detect a fire in infrared curing ovens and
    shutdown the oven without false alarming.
     Need for a More Reliable Flame Detector
   Without fail, must respond to fires within 500 milliseconds as
    required by NFPA 33 and not false alarm to non-fire radiant
    energy sources.
   Cannot be blinded by smoke and paint overspray mist in its
    optical path.
   Has to provide protection from contamination on the lens,
    substantially reducing the maintenance required for the
    cleaning of the flame detector lens.
   Must provide definitive information to postulate the cause of a
    fire in order to prevent its re-occurrence.
    FS System 10 - The Reliable Flame Detector
       Fire Sentry Multi-Spectral Wide Band IR, Near
       Band IR and Visible Band (0.7 to 3.5 microns)

    Wide Band IR sees ALL paint spray fires and does not rely
     on unpredictable 4.3 micron narrow band CO2 emission.

    Does not false alarm to IR backgrounds, arcs, sparking,
     welding, sunlight, reflected sunlight, fluorescent, halogen,
     sodium, or mercury arc lights, etc.

    Monitors the level of contamination on detector lens
     through automatic, computer-controlled self-test.

    Quickly detects flickering, non-fireball fires.
    FS System 10 - The Reliable Flame Detector
       Fire Sentry Multi-Spectral Wide Band IR, Near
       Band IR and Visible Band (0.7 to 3.5 microns)

   Detects all types of fires: Hydrocarbon and Non-Hydrocarbon
    because senses the blackbody radiant heat emitted by a fire;
    does not rely on the unpredictable CO2 spike at 4.3 micron.

   “Sees Through” smoke, contaminants on detector lens, and
    aerosols.

   Senses over 88% of the total radiant energy emitted by a fire
    because of Wide Band Infrared, (0.7 to 3.5 microns).
Wide Band IR Sees 60 Times More Fire Blackbody Radiant
           Energy as 4.3 Micron Narrow Band

                   Quantum Sensor
                  Heart of the Detector
            Quantum Photoelectric IR Sensors
Quickly responds to Wide Band infrared radiant energy. Incident photon
radiant energy from a fire causes quantum electrons to be released from
the crystal lattice in microseconds. Does not require absorbing heat as do
thermopile and pyroelectric sensors. Detects many times more of the total
Planckian blackbody radiant energy emitted by a fire than narrow band
thermopile or pyroelectric sensors.
      Directly senses fire at speed of light
      Fast response to “fire-ball” type paint spray fires
      Fast response cool-burning alcohol fires
      Will detect a “reflash” fire
       DIGITAL vs. ANALOG Fire Detection
   ANALOG fire detectors do not have intelligence and
    memory - can only process minimal instantaneous radiant
    energy information from the fire.

   ANALOG cannot digitally record pre-fire data from a fire for
    analysis of the cause of the fire.

   ANALOG can drift out of calibration because of aging,
    thereby affecting the detector’s sensitivity range.

   ANALOG circuitry for modern performance criteria is costly
    as compared to digital circuitry.
      DIGITAL vs. ANALOG Fire Detection

   Fire Sentry DIGITAL fire detectors are stable, long-life &
    trouble-free.
   Fire Sentry DIGITAL fire detectors are factory
    programmable for customizing for specific applications.
   Fire Sentry DIGITAL SIGNAL PROCESSING (DSP) for
    fast fire detection of fireball (initially non-flickering) and
    flickering non-fireball fires without false alarms.
   Fire Sentry DIGITAL fire detectors continuously adapt to
    changes in the IR background and temperature.

   FS System 10 - Proven Technology

 Fire Sentry’s multi-spectral digital flame
detection technology has been protecting
automatic electrostatic painting booths . . .

 with millions of successful operational
         hours for over 10 years
FS System 10 Technology Provides Four Key Paybacks
        to the Electrostatic Finishing Industry


Based on feedback from customers in
the Electrostatic Finishing Industry . . .

Four key paybacks are being realized
with the use of this proven,
multi-spectral digital technology.
Payback #1: Immunity to False Alarms


  Immunity to false alarms
      because of multi-spectral sensing,
      Digital flame detection technology
  Benefits:
    Eliminates costly interruptions and
    production downtimes
Payback #1: How Detector Differentiates Between
            Real Fire and False Alarms



  Knows the difference between a real fire and false alarm
                    radiant energy sources

  Digital Signal Processing (DSP) intelligently analyzes multi-
                     spectral data from the
               Wide band IR, Near band IR, and
                  Visible band sensor array
    Payback #1: How Detector Differentiates Between
                Real Fire and Non-Fire False Sources

    Measures the CHANGE in radiant energy, and

    Measures the AMOUNT of radiant energy emitted from a fire

    Enables the Detector to DIFFERENTIATE a real fire from a
     non-fire (i.e., infrared ovens, arcing, sparks, flashlights, direct
     or reflected sunlight, overhead lighting, etc.).
Payback #2: Fast One-Half Second Response Causes
            Self-Extinguishment of the Fire

                          1st Stage
   The first level ALERT / FIRE EARLY WARNING output
   signal complies with NFPA 33 Standard for spray paint
    applications by reacting to a spray gun fire in one-half
                          second . . .
   The first level output signal is designed to automatically
   initiate the shut down of the spray gun to cause most
             fires to self-extinguish without damage.
Payback #2: One-Half Second Response Causes
            Self-Extinguishing of the Fire

                          1st Stage
    ALERT detects a “fireball” type paint spray fire.
    FIRE EARLY WARNING detects flickering fires in the
    booth.
    Both ALERT and FIRE EARLY WARNING output
    signals are combined into one output signal.
Payback #2: 2 ALARM Stage response


                             2nd Stage
   If the fire does not self-extinguish . . .

  the 2nd Stage ALARM output signal provides fast response
  in five seconds for optional application of fire suppression
  agents.
Payback #3: Air Shields or Protective Covers Eliminate
            Detector Cleaning Costs

   Conventional OLD TECHNOLOGY UV, IR, IR/IR, and UV/IR
    Detectors, are sensitive to any lens contamination such as paint
    overspray, powder coating residue, oil, etc. They may not
    respond to a fire even with a minimal amount of contaminant on
    the detector’s window lens.
   Conventional OLD TECHNOLOGY Detectors are require
    continual cleaning , which is costly and unacceptable in the
    manufacturing environment.
Payback #3: Air Shields or Protective Covers
            Eliminate Detector Cleaning Costs


    Some Dual IR/IR and other Conventional Detectors DO
     NOT HAVE automatic window lens cleanliness self-test so
     there is no way to determine when the Detector is BLINDED
     in either one or both of its window lens . . unless the paint
     booth is shut down and the fire detection panel is disarmed
     in order to perform a manual test .
Payback #3: Air Shields or Protective Covers
             Eliminate Detector Cleaning Costs
  Most other UV/IR and UV only have automatic window lens
   cleanliness self-test. However, the UV channel is easily
   blinded by paint or powder. The result is frequent “self-test”
   nuisance FAULTS. The end-user either ignores these
   FAULTS or disables the detection system.
    Nordson Corporation* used to use UV only flame detectors
     prior to 1988, and it was found over one-half of the installed
     base users disabled the detectors because of either
     nuisance FAULTS or false alarms.
 *Largest Paint Booth manufacturer in the US.
 Payback #3: Air Shields or Protective Covers
               Eliminate Detector Cleaning Costs
1. A proven and effective air shield system developed for
   FS System 10 detectors and used in Liquid and Powder
       Coating applications.

2. Specially designed Disposable Protective Covers. The covers
   simply “snap” on and off the detector, protecting the lens from
   contamination from paint overspray, eliminating unscheduled
   maintenance required to clean the detector lens.

  The covers can be installed and removed from the detectors
  from ground level by utilizing an extension pole available from
  by Fire Sentry.
Payback #4: Recorded Digital Fire Event Information with
              FirePic
   FirePic provides retrieval of recorded pre-fire spectral data
    from detector’s non-volatile memory for analysis and
    display. It is a graphical display of relative spectral
    intensities versus time preceding and during the fire.
   FirePic records the last six (6) fire events, for a period of
    (8) seconds each, in permanent, non-volatile memory.
    Each event is time and date stamped by a built-in real-
    world time clock.
   No other manufacturer of industrial flame detectors can
    offer the features of FirePic that allow for analysis and
    diagnosis of the possible cause of the fire.
                    Ordering Tips…..
   Unitized detector or detector with controller?
    Specify the application.
   Wall-mount controller - specify cable lengths if different
    from standard 50 feet.

    them?
   ….and don’t forget a Test Lamp
                Installation Tips…..

   Wiring, wiring, wiring…..
   Grounding the system.
   Grounding cable shield at the controller.
   Use of wrist strap stops static damage to micros.
