2 Model FS System 10 2 Stage Unitized Flame Detector and Controller Based Systems for Electrostatic Paint Spray Booth Fire Detection FSC protects Jeep paint booths!

3 FS System 10 - Primary Applications s Automotive Electrostatic paint spray lines. s Liquid paint & powder coating spray lines s Liquid & Powder coating booths s Paint storage and mixing s Aerosol filling applications s Diesel generators s Gas compressor stations

4 Flame Detector Comparisons

5 Flame Detectors - Old Technology Ultraviolet Only (UV) (0.18 to 0.26 microns) s Highly false alarm prone to arcs, corona discharges, welding, halogen lights, sparks, etc. s Easily blinded by contaminants on lens such as oil film, paint, powder, chemicals, smoke, suppressants,etc.

6 Flame Detectors - Old Technology Single band Infrared (IR) (4.3 micron) s False alarm prone to heat sources, lights, ovens, etc. s Slow response to “fireball” type fires. s Relies on unpredictable CO 2 narrow band emission line

7 Flame Detectors - Old Technology UV/IR s Far less false alarm prone than UV only or single band IR flame detectors. s 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. s Unreliable - UV tube and UV self-test source prone to failure.

8 Flame Detectors - Old Technology Dual Frequency IR/IR (4.3 micron with 3.8 micron background reference) s Slow response to paint spray fireball type fires because of narrow band 4.3 micron signal. s Blinded by contaminants because of narrow bands. s No self-test to determine if sensors are blinded. s Bulky housing and obsolete analog technology.  No re-flash fire detection if cold CO 2 used as suppression - absorbs hot CO 2 IR from a fire.

9 Need for a More Reliable Flame Detector s Flame detector must have two stages of response: 1st Stage - shutdown the spray guns 2nd Stage - signal for suppression release. s Must detect both fireball and a flickering non-fireball fire s Has to detect all types of burning materials including solvent- based paints, waterborne paints, powder paints and alcohol for cleaning. s Must be able to detect a fire in infrared curing ovens and shutdown the oven without false alarming.

10 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. s Cannot be blinded by smoke and paint overspray mist in its optical path. s Has to provide protection from contamination on the lens, substantially reducing the maintenance required for the cleaning of the flame detector lens. s Must provide definitive information to postulate the cause of a fire in order to prevent its re-occurrence.

11 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 CO 2 emission. s Does not false alarm to IR backgrounds, arcs, sparking, welding, sunlight, reflected sunlight, fluorescent, halogen, sodium, or mercury arc lights, etc. s Monitors the level of contamination on detector lens through automatic, computer-controlled self-test. s Quickly detects flickering, non-fireball fires.

12 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) s 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 CO 2 spike at 4.3 micron. s “Sees Through” smoke, contaminants on detector lens, and aerosols. s Senses over 88% of the total radiant energy emitted by a fire because of Wide Band Infrared, (0.7 to 3.5 microns).

13 Wide Band IR Sees 60 Times More Fire Blackbody Radiant Energy as 4.3 Micron Narrow Band 4.3 micron Narrow Band.7 to 3.5 micron Wide Band IR Wavelength (microns).1 1.0 10

14 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. s Directly senses fire at speed of light s Fast response to “fire-ball” type paint spray fires s Fast response cool-burning alcohol fires s Will detect a “reflash” fire

15 DIGITAL vs. ANALOG Fire Detection s ANALOG fire detectors do not have intelligence and memory - can only process minimal instantaneous radiant energy information from the fire. s ANALOG cannot digitally record pre-fire data from a fire for analysis of the cause of the fire. s ANALOG can drift out of calibration because of aging, thereby affecting the detector’s sensitivity range. s ANALOG circuitry for modern performance criteria is costly as compared to digital circuitry.

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

23 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

24 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.

25 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

26 Payback #1: How Detector Differentiates Between Real Fire and False Alarms Knows the difference between a real fire and false alarm radiant energy sources D igital S ignal P rocessing (DSP) intelligently analyzes multi- spectral data from the Wide band IR, Near band IR, and Visible band sensor array

27 Payback #1: How Detector Differentiates Between Real Fire and Non-Fire False Sources s Measures the CHANGE in radiant energy, and s Measures the AMOUNT of radiant energy emitted from a fire s 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.).

28 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.

29 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.

30 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.

31 Payback #3: Air Shields or Protective Covers Eliminate Detector Cleaning Costs s 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. s Conventional OLD TECHNOLOGY Detectors are require continual cleaning, which is costly and unacceptable in the manufacturing environment.

32 Payback #3: Air Shields or Protective Covers Eliminate Detector Cleaning Costs s 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.

33 Payback #3: Air Shields or Protective Covers Eliminate Detector Cleaning Costs s 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. s 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.

34 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.

35 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. s 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. s 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.

36 Ordering Tips….. s Unitized detector or detector with controller? Specify the application. s Wall-mount controller - specify cable lengths if different from standard 50 feet. s Specify option for controller or card controller. s Specify detector sensitivity or booth size. s Air shield or disposable protective cover - do you need them? s ….and don’t forget a Test Lamp

37 Installation Tips….. s Wiring, wiring, wiring….. s Grounding the system. s Grounding cable shield at the controller. s Use of wrist strap stops static damage to micros. s Wall-mount system - must have odd and even serial numbered detectors. s Practice downloading FirePic & the Event Log.
