FlameGard® Series of Flame Detectors 5 Fast, reliable optical ﬂame detection for hydrocarbon-based ﬁres

FLAME

MSA FlameGard Flame Detectors provide constant monitoring for fire or flame by detecting the characteristic ultraviolet (UV) and/or infrared (IR) radiation from a hydrogen or hydrocarbon-fueled fire. They operate as a stand alone unit without a control panel, or can be connected to a fire or security panel via an internal alarm or accessory relay. FlameGard Detectors reduce the possibility of false alarms because the units must receive the proper wavelength, duration and intensity of the fire’s radiation before an alarm is activated. 3 Versions: FlameGard UV Flame Detector: monitors UV radiation FlameGard UV/IR Flame Detector: dual-optical sensing monitors UV and IR radiation FlameGard IR3 Flame Detector: patented triple-IR technique monitors IR radiation with enhanced immunity to false alarms Simplicity/ Ease of Use • Easy to operate and maintain • Easily mounted via a simple bracket or the optional Swivel Mount Kit • High-speed response with false alarm suppression • 4 to 20mA and RS-485 outputs • Alarm, accessory and fault relays • Manual or automatic built-in test feature performs a complete functional test as desired, or routinely during operation • Optional MSA Fire Simulator provides flame-free testing

Flexibility • Stand alone operation or connection to standard four wire fire control panels • User programmable to various configurations Durability • Enclosed in heavy-duty, copper-free, explosion-proof aluminum or stainless steel housings FlameGard IR3 Detector • Uses a patented triple-infrared (IR) detection technique that offers two to three times the detection distance (up to 200 ft) of conventional IR or UV/IR detectors. • This technique uses the signal from 3 different sensors, each looking at a different infrared frequency. All the signals are checked for the proper ratio and relationship to each other before an alarm is given. • This enhances immunity to false alarms, though not at the expense of sensitivity to a real fire or flame condition.

    

Instrument Calibration Whether an instrument warns and/ or alarms at the proper time depends on its ability to translate the quantity of gas it detects into an accurate reading. “Calibration” refers to an instrument’s measurement accuracy relative to a known concentration of gas. Gas detectors perform relative measurements: rather than independently assessing the quantity of gas present, they measure the concentration of the air sample and then compare it to the known concentration of the gas that the instrument is conﬁgured to sample. This “known concentration” serves as the instrument’s measurement scale, or reference point. If the instrument’s reference point has moved, then its reading will also move. This is called “calibration drift” and it happens to most instruments over time. (Common causes of calibration drift include the normal degradation of sensors, exposure of the sensor to poisons, and harsh operating conditions.)

There are two methods of verifying instrument calibration: through a functional or “bump” test (or span check) or by performing a full calibration. Each is appropriate under certain conditions.

Full Calibration A full calibration is the adjustment of the instrument’s reading to coincide with known concentrations (generally a certiﬁed standard) of zero and span gases, to compensate for calibration drift. In most cases, a full calibration is only necessary when an instrument does not pass the bump test (or after it has been serviced).

• after the unit has operated in varying background conditions (e.g. humidity levels) • after exposure to extreme conditions (e.g. high temperature or humidity) If the instrument fails the zero check, then a zero adjustment—which sets the instrument to true zero—should be performed. Frequency of Calibration The frequency of calibration depends on the sensor’s operating time, conditions of use (including chemical exposure) and user experience with the instrument. New sensors should be calibrated more often until the calibration records prove sensor stability. The calibration frequency can then be reduced to the schedule set by the safety ofﬁcer or plant manager. Before calibrating the sensors, it is good practice to apply power to the unit to allow the sensor to adapt to the new environment. Sensors should be powered at least one full hour before any calibration attempt is made.

Zero Check A zero check is performed to verify that the instrument reads true zero (also referred to as the “baseline”) in an environment in which no amount of target gas is present. Common situations in which a zero check is performed include: • after exposure of the sensor to a sensor contaminant • after the sensor has been exposed to a very high concentration of the target gas • as the sensor ages, since it may gradually drift

When an instrument experiences calibration drift it can still measure the quantity of gas present, but it cannot convert it into an accurate numerical reading. Regular calibration with a certiﬁed standard gas concentration updates the instrument’s reference point, re-enabling it to produce accurate readings.

Bump (or Span) Check A bump check is a means of verifying calibration by exposing the instrument to a known concentration of test gas. The instrument reading is then compared to the actual quantity of gas present (as indicated on the cylinder). If the instrument’s response is within an acceptable range of the actual concentration then its calibration is veriﬁed. When performing a bump test, the test gas concentration should be high enough to trigger the instrument alarm. If the bump test results are not within the acceptable range, then a full calibration must be performed.

STEP 2: Create drawings indicating all potential leak sites, as well as the severity of each site’s hazard potential. There are two main categories of hazardous locations: A. Potential gas discharge points. These are places where hazardous gases may be released, such as valve stem seals, gaskets, compression fittings and expansion joints. B. Potential contact areas. These are places where hazardous gases may endanger workers, or damage equipment or property. Examples include populated areas, confined spaces, pits, stairwells, crawl spaces, shelters, and residential, business and industrial environments located nearby. STEP 3: Since gases do not always behave in the same way, take air flow conditions, as well as potential gas pockets, into consideration before placing sensors. MSA smoke tubes (P/N 458481) can be useful in measuring the direction and rate of air flow to determine areas where gases may accumulate.

In general, when placing sensors the following principles should be considered: • Place sensors in areas where the air currents are likely to produce the highest gas concentration, including areas where gas buildup is likely, such as corners or stopping points of moving devices that release gas. • If you are attempting to take a representative room sample, do not place sensors near entrances or fresh air vents (because the sample concentration will be diluted by incoming air) unless there is a need to sample that speciﬁc area of the room. • Place sensors close to the possible gas/leak source. • Place combustible gas sensors between the potential leak and the ignition source. • Place toxic gas and oxygen sensors between the potential leak and the populated area, and in the workers’ breathing zone. • Consider ease of access to the sensor for maintenance requirements, such as periodic calibration. Use a remote sensor for high or inaccessible locations.

• Avoid mounting sensors near radio transmitters or other RFI-producing sources (e.g., welding activity and induction heaters), to reduce possible RF interference. • Avoid locations where airborne particles may coat or contaminate the sensor, such as paint booths. • Install sensors in a position that prevents water or dust accumulation on the sensor head (which may impede the diffusion of gas into the sensor). The preferred position is facing downward, but horizontal placement is also acceptable. • Facility air intakes are generally good locations for sensors. • Ensure that the entire area in question is sufﬁciently monitored, including little-used areas such as closets, warehouses and other storage areas. • Factor in the vapor density of the monitored gases when compared to air.

Combustible Gas Sensors • Hydrogen and methane are lighter than air, so place sensors near the ceiling, and in ceiling corners where pockets of air may collect. • For electric motor monitoring, place sensors near the ignition source. • Gasoline is heavier than air, so place sensors near—but not directly on— the ﬂoor. • When monitoring multiple combustible gases, calibrate the instrument for the least sensitive gas. Toxic & Oxygen Gas Sensors • Place carbon monoxide and carbon dioxide sensors for indoor air quality monitoring near air intake ducts. • In general, in occupied areas (e.g., conﬁned spaces) monitor for oxygen and toxic gases in the workers’ breathing zone (4-6 ft.). This will vary, depending on whether the density of the gas is heavier, the same as, or lighter than, air or oxygen.

Toxic & Combustible Sensors • Place sensors near the potential release source for process monitoring applications (e.g., pipelines, valves). • Gas cylinder storage areas: If they are ventilated, place sensors near the return air vent. • Acid/ solvent drum storage areas: These gases are heavier than air (e.g., heavy hydrocarbons) so place sensors close to the ground and in corners where air may collect in pockets. • If the hazard is outside, place sensors near the air intake for both combustible and toxic gas monitoring; if the hazard is inside, place sensors near the exhaust. • Some gases may collect in pockets in room corners, at both ﬂoor and ceiling levels. Place sensors in these areas if necessary. Refrigerant Monitor Placement • ASHRAE 15 states that a refrigerant monitor capable of detecting the TLV for a refrigerant gas must be installed in a mechanical equipment room. • Place the end of the sample line in the location most likely to develop a refrigerant gas leak or spill. Such areas

include valves, fittings and the chiller itself. Also, monitor any refrigerant storage location. It is good practice to keep all sampling lines as short as possible when an aspirated or pumped sampling system is used. • Since most refrigerant gases are heavier than air, monitor these gases close to the floor. Any pits, stairwells or trenches are likely to fill with refrigerant gas before the main area. It may be necessary to monitor these locations for refrigerant gas. • If ventilation exists in the chiller room, MSA smoke tubes (P/N 458481) will help to determine the most appropriate gas monitoring locations. • Monitor displays can be placed just outside the doorway of the monitored area, enabling personnel to check the status before entering the area. • ASHRAE Standard 147P states the following: 4.8 Refrigerant Monitor. On large refrigerating systems for which a refrigerant monitor is required per ASHRAE 15, a refrigerant monitor capable of detecting refrigerant concentrations of 1 ppm by volume or less shall be used to provide early warning of leaks.
