DESCRIPTIONDESCRIPTIONFireHawk M7 Air Masks from MSA are pressure-demand,self-contained breathing apparatus (SCBA) certified by theNational Institute for Occupational Safety and Health(NIOSH) for use in atmospheres immediately dangerous tolife or health:``Immediately dangerous to life or health’’ means condi-tions that pose an immediate threat to life or health orconditions that pose an immediate threat of severe expo-sure to contaminants, such as radioactive materials,which are likely to have adverse cumulative or delayedeffects on health [Title 42 CFR, Part 84.2, (Q)].This Air Mask complies with the National Fire ProtectionAssociation (NFPA) Standard 1981 for Open-Circuit Self-Contained Breathing Apparatus for Fire FightersThis Air Mask has been designated by NIOSH as beingCBRN (chemical, biological, radiological, and nuclear)Agent Approved. It complies with the special tests underNIOSH 42 CFR 84.63(c); Chemical Agent Permeation andPenetration Resistance Against Distilled Sulfur Mustard(HD) and Sarin (GB) and the Laboratory RespiratorProtection Level (LRPL) tests.The FireHawk M7 Air Mask consists of the followingcomponents.• PR14™ First Stage Regulator• Firehawk Second Stage Regulator• Cylinder and Valve Assembly• Audi-Larm™ Audible Alarm with URC Assembly• FireHawk M7 Carrier and Harness Assembly• Ultra Elite®Facepiece• FireHawk M7 HUD• FireHawk M7 Control Module• FireHawk M7 Power ModuleOptional FIREHAWK M7 AIR MASK COMPONENTS• Clear Command®Communications System• FireHawk M7 Telemetry Module• ExtendAire™ System• Quick-Fill System• Rescue BeltFIREHAWK M7 AIR MASK COMPONENTSPR14 FIRST STAGE REGULATORThe PR14 First Stage Regulator reduces the pressurefrom the cylinder and valve assembly to an intermediatepressure, which is in turn further reduced by the FirehawkSecond Stage Regulator to a pressure that is respirableby the user.The PR14 First Stage Regulator incorporates a down-stream design and dual springs.The regulator incorporates a large, easily replaceable, sin-tered filter to capture particulates that may be in the airstream.FIREHAWK SECOND STAGE REGULATORThe Firehawk Regulator is a pressure-demand regulator,which maintains a positive pressure in the facepiece whilethe air mask is in use.The Firehawk Regulator attaches to the facepiece via aslide-to-connect or a push-to-connect feature.The Firehawk Regulator has two available covers, purgeand hard cover. The purge cover offers the user the abilityto manually activate the regulator or to provide a quickburst of air during use without using the bypass knob.There are also two types of Firehawk Regulator intermedi-ate pressure hose connections, threaded and quick-con-nect.CYLINDER AND VALVE ASSEMBLY*as approved by NIOSHThe cylinder valve includes a metal valve body, threadedconnection for filling and attachment of the Audi-LarmAlarm, handwheel, safety disc (burst disc), and pressuregauge.The pressure gauge continuously shows the air pressurein the cylinder.The handwheel is used to open and close the cylindervalve.5TAL 708 (L) Rev. 1 - 10082858Capacity Pressure Rated Svc*Cubic Ft. psig Life (Min.)45 4500 3088 4500 6045 2216 3045 2216 3060 3000 3066 4500 45
AUDI-LARM ALARM WITH URC ASSEMBLYThe Audi-Larm Alarm rings when there is approximately25% of the air mask’s rated service time remaining andwhen the cylinder valve is first opened, providing an audi-ble indication that the alarm is working properly.A high pressure hose delivers air at cylinder pressure fromthe Audi-Larm Alarm to the PR14 First Stage Regulator.Note: The remaining service time calculations are basedon a 40 LPM (liters per minute) NIOSH breathing rate.All FireHawk M7 Air Masks are equipped with an Audi-Larm Alarm that includes a URC Assembly (UniversalRescue Connection). The URC Assembly is a male quick-fill inlet for use by Rapid Intervention Crews for emer-gency filling of the SCBA or during transfill operations.Also included with the URC Assembly is a pressure reliefvalve for protection of the cylinder burst disc.FIREHAWK M7 CARRIER AND HARNESS ASSEMBLYDO NOT use this carrier and harness assembly as avertical raising or lowering device. Failure to followthis warning can result in serious personal injury ordeath.The carrier consists of a backplate, a cylinder band withlatch to hold the cylinder, and a harness, consisting ofshoulder pads, chest strap (optional), adjustable pull straps,waist belt, waist belt mounted regulator retainer, swivelinglumbar pad (optional), and Rescue Belt (optional).ULTRA ELITE FACEPIECEThe facepiece is available in three sizes (Small, Medium,and Large).The facepiece lens is super-hardcoated to meet therequirements of NFPA 1981.The facepiece has a low-resistance, pressure-demandexhalation valve.An inhalation check valve in the inlet housing keeps mois-ture and contaminants out of the Firehawk Regulator.The facepiece has a speaking diaphragm for clear com-munication.FIREHAWK M7 HUDThe FireHawk M7 HUD, located on the Ultra EliteFacepiece allows a user to see cylinder pressure in onequarter cylinder increments, PASS pre-alarms, battery sta-tus, and telemetry information (optional) while wearing theair mask.FIREHAWK M7 CONTROL MODULE (PASS DEVICE)The FireHawk M7 Control Module is the user’s interfacewith the air mask.The FireHawk M7 Control Module is equipped with ananalog gauge as well as an LCD to provide the user vitalinformation: numeric and iconic cylinder pressure, batterystatus, thermal alarm (optional), and time remaining.If the air mask is equipped with the optional FireHawk M7Telemetry Module, the radio link status and evacuationalarms are displayed.The integrated PASS motion sensor is housed within theFireHawk M7 Control Module.FIREHAWK M7 POWER MODULE (PASS DEVICE)The FireHawk M7 Power Module on the lower portion ofthe backplate houses the batteries, serves as the cylinderstop, emits audible PASS alarms, and has buddy lights.The FireHawk M7 Power Module is linked to the FireHawkM7 Control Module via the power cable.OPTIONAL FIREHAWK M7 AIR MASK COMPONENTSCLEAR COMMMAND COMMUNICATION SYSTEMThe Clear Command Communication System is an elec-tronic speech projection system available with either anamplifier or an amplifier with radio interface connection.DESCRIPTION6TAL 708 (L) Rev. 1 - 10082858End ofServiceCylinder Remaining Service TimeTime (Approx.)

DESCRIPTIONFIREHAWK M7 TELEMETRY MODULEThe FireHawk M7 Telemetry Module provides the firefight-er with two-way communication with Incident Command.The firefighter’s vital statistics such as cylinder pressure,service time remaining, PASS alarm, low battery alarm,and thermal alarm are transmitted back to IncidentCommand. Also, the firefighter has the ability to be evac-uated remotely by Incident Command. The radio trans-mitter is located inside of the FireHawk M7 PowerModule.EXTENDAIRE SYSTEMThe ExtendAire System, located on the user’s left chest,enables two users to share a common air supply duringemergency escape. The users can couple the FirehawkSecond Stage Regulator from one user to the intermedi-ate pressure manifold of the other user. Both users willreceive intermediate pressure air from the donor's firststage regulator and cylinder. The duration of the remainingair supply will be reduced by at least half.The SCBA is approved by NIOSH without inter-connectingtwo users to one apparatus. NIOSH does not certify“buddy breathers”. Therefore, the attachment of thereceiver's regulator to the donor's apparatus voids theNIOSH approval for both air masks.RESCUE BELTThe MSA Fire Service Rescue Belt is a personal escapesystem integrated into an FireHawk M7 Carrier andHarness Assembly. The system is designed to provide theuser a means of escape from an elevated position. Use ofthe Rescue Belt must be in accordance with the user’s firedepartment procedures.

COLD WEATHER OPERATIONSuggested Procedures for Cold Weather OperationMoisture can cause problems in the air mask if it freezes.However, moisture can cause freezing problems even ifthe surrounding air is above freezing. Air flowing from thecylinder through the first and second stage regulatorsdrops from cylinder pressure to close to atmosphericpressure very quickly. This causes the air to expand andcreates a cooling effect. Although the surrounding tem-perature may be warmer than 32°F, the temperature insidethe regulator may be lower. Any water inside could turn toice and restrict airflow.1. To keep moisture from entering the mask mountedregulator, keep the Firehawk Regulator in the beltmounted regulator holder when not in use.2. When the air mask is away from heat, water spray canfreeze on the Firehawk Regulator surface. Ice canbuild up and bind the side buttons or the bypassvalve. Before entering or re-entering a hazardousatmosphere, ensure the side buttons and bypass valveare ice-free and operating properly. Periodically checkthe bypass to be sure it is ice-free.3. Moisture can enter through the cylinder valve or cou-pling nut when cylinders are replaced on the air mask.When replacing cylinders, ensure moisture or contami-nation does not enter the system. Remove any icefrom these fittings. Wipe the coupling nut threads andcylinder valve threads before installing a new cylinder.Water can contaminate the system and freeze.4. NIOSH certification requires a nosecup at tempera-tures below 32°F. The nosecup reduces lens foggingand must be used whenever freezing conditions areencountered.5. When cleaning the air mask, ensure water does notenter the facepiece or Firehawk Regulator.6. Thoroughly dry the facepiece and mask mounted reg-ulator after cleaning and disinfecting. FollowConfidence Plus® Cleaning Solution instructions.Note: Fresh batteries must be installed in the FireHawkM7 HUD and FireHawk M7 Power Module prior to storageof the Air Mask at cold temperature for an extended peri-od of time.24TAL 708 (L) Rev. 1 - 10082858
AUDI-LARM ALARM WITH URC ASSEMBLY OPERATIONOPERATION PRECAUTIONS FOR USING THE URC(UNIVERSAL RESCUE CONNECTION) ASSEMBLY1. The URC Assembly can only be used to fill approvedair mask cylinders.2. The URC Assembly is not to be used as a "BuddyBreather" such that two users are sharing the air sup-plied by one air mask cylinder simultaneously doing sowill void NIOSH approval.3. The user is responsible for the air supply, which mustmeet the requirements of Compressed GasAssociation Specification ANSI/G-7.1, QualityVerification Level (Grade) D Gaseous Air or better, witha moisture dew point of not greater than -65°F(24ppm water vapor, normal). In fire service applica-tions, MSA recommends breathing air quality in accor-dance with NFPA 1989. Pressures at the inlet of thequick-fill hose must not exceed that of the air mask(2216 psi or 4500 psi).4. Using the 3000 psi URC Assembly to fill cylinders, thecylinder can only be filled to 2216 psi. If the pressureexceeds 2216 psi a relief valve in the URC Assemblywill vent at approximately 2525 psi or as low as 2400psi. A 3000 psi cylinder can only be filled to 3000 psiby using a secondary air supply; the 3000 psi URCAssembly cannot be used for filling a 3000 psi cylinder.5. The user also is responsible for connecting the quick-fill hose to an appropriate secondary air supply.6. The cylinder must be inspected for damage beforecharging.7. If filling cylinders in fresh air using the URC Assemblytopping off the cylinder is recommended after thecylinder has cooled from initial fill. Topping off a cylin-der after it has cooled will ensure proper service time.All NFPA 1981:2007 approved air masks are equippedwith a URC Assembly (Universal Rescue Connection) fit-ting. The URC Assembly is a male quick-fill inlet for useby Rapid Intervention Crews for emergency filling opera-tions. The system also includes an automatically resettingpressure relief valve. The air mask can also be equippedwith a shoulder mounted Quick-Fill System, unless usinga 3000 psi URC Assembly, the 3000 psi URC Assemblycan not be used with Quick-Fill System. For additionalinformation on using the Quick-Fill System, refer to theQuick-Fill System section of the manual.• DO NOT use the URC Assembly as a "BuddyBreather" such that two users are sharing the airsupplied by one approved air mask cylinder simul-taneously; doing so will void NIOSH approval.• The URC Assembly must be used by trained RapidIntervention Crews only using procedures devel-oped for rapid intervention.• DO NOT install a Quick-Fill System and 3000 psiURC assembly on the same air mask. Combiningthese assemblies on the same air mask will notallow the relief valve in the 3000 psi URC Assemblyto open as designed. Failure to follow this warningcan result in serious personal injury or death.•DO NOT transfill (be a donor) using a 3000 psi URCAssembly. The 3000 psi URC Assembly has acheck valve that does not allow cylinders to trans-fill (be a donor).• Using the 3000 psi URC Assembly to fill cylinders,the cylinder can only be filled to 2216 psi. If thepressure exceeds 2216 psi a relief valve in the URCAssembly will vent at approximately 2525 psi or aslow as 2400 psi. A 3000 psi cylinder can only befilled to 3000 psi by using a secondary air supply;the 3000 psi URC Assembly cannot be used for fill-ing a 3000 psi cylinder.• DO NOT lubricate the URC Assembly fittings. Donot permit oil, grease, or other contaminants tocome in contact with the quick-fill fittings.• The hose assemblies and fittings are designed tobe used with Quality Verification Level (Grade) D orbetter air as defined by ANSI/CGA G-7.1.TRANS-FILLING AIR FROM A SECONDARY AIR SUPPLY. Infire service applications, MSA recommends breath-ing air quality in accordance with NFPA 1989.• DO NOT use any transfilling hose assembly or fit-tings other than those supplied by MSA specificallyfor the URC Assembly for filling operations.Failure to follow the above warnings can result in seri-ous personal injury or death.Note: The URC Assembly may be used for transfill opera-tions as described in this manual. Standard operating pro-cedures should be developed for use of the URC Assembly.The URC Assembly must be used only by qualified, trainedpersonnel who have carefully read and understood theseinstructions, cautions, and warnings. NIOSH approvals ofSCBA from MSA are maintained while transfilling air only ifappropriate hose assemblies from MSA are used. URCAssembly or hose assemblies and fittings are rated for amaximum working pressure of 4500 psi. NIOSH approvalis maintained only when using the following hose assem-blies: 485331, 802687, 802688, 802689, 802690, and48332, for filling cylinders in IDLH atmospheres.A secondary air supply stores compressed breathing airuntil needed to refill air mask air cylinders. When transfill-ing, the secondary air supply pressure must be greaterthan air mask cylinder pressure. Examples of air suppliesinclude: cascade air cylinder refilling systems; high pres-sure compressor systems with a fixed reservoir; or aportable air system such as the RescueAire™ System.DO NOT connect a high pressure air mask to a sec-ondary air supply with a pressure greater than 4500psi. The high pressure air mask is rated for a maxi-mum working pressure of 4500 psi. Failure to follow25 TAL 708 (L) Rev. 1 - 10082858
AUDI-LARM ALARM WITH URC ASSEMBLY OPERATIONthe above warnings can result in serious personalinjury or death.FILLING INSTRUCTIONS FOR USING THE URCASSEMBLYFor Rapid Intervention Crews:Note: Rapid Intervention Crews should use a separate airsupply such as MSA’s RescueAire portable air supply sys-tem to fill the air mask in an IDLH atmosphere.NIOSH DOES NOT approve the use of the URCAssembly to transfer air from the cylinder of one airmask to another air mask. Failure to follow this warn-ing can result in serious personal injury or death.1. Connect the quick-fill hose to the air supply source ordonor air mask.a. Push the female fitting of the hose on the male fit-ting until it snaps in place. Pull on the hose to besure the fitting snapped into place.b. Turn the air supply on.If there are leaks from either female fitting, or alongthe hose, depressurize the hose and correct the prob-lem. Such leakage can result in increased fill time.Failure to follow this warning can result in serious per-sonal injury or death.2. Attach the quick-fill hose to the URC Assembly orshoulder mounted quick-fill fitting (optional).a. Remove the rubber dust cap from the male inlet fit-ting on the URC Assembly or quick-fill fitting. Besure that the cylinder valve is fully opened.b. Remove the rubber dust cap from the female fittingon the quick-fill hose.c. Push the female fitting of the hose onto the male fit-ting of the URC Assembly or quick-fill fitting until itsnaps in place. Pull on the hose to be sure the con-nection is secure. Filling immediately begins whenthe female fitting fully engages with the URCAssembly or quick-fill fitting.d. After approximately 45-60 seconds, the pressurebetween the secondary air supply and the air maskcylinder will be equal.If serious leakage is noticed from either of the twofemale fittings, or anywhere along the hose, discon-nect the female fittings and return to fresh air immedi-ately. Failure to follow this warning can result in seri-ous personal injury or death.Note: If the secondary air supply does not have a suffi-cient volume of air, the air mask cylinder will not reach fullservice pressure.3. Compare the air mask cylinder gauge and theFireHawk M7 Control Module gauge to the secondaryair supply pressure gauge reading. If the readings arethe same, pressure is equal.4. To disconnect the quick-fill hose after transfilling, pullback the gray sleeve on the female fitting of the quick-fill hose. The hose fitting and the URC Assembly willseparate. A hiss or pop may be heard as the fittingsseparate and the high pressure air is sealed off.5. Immediately install the dust cover on the URCAssembly or shoulder mounted quick-fill male fitting.6. The air mask cylinder is ready for service if the cylin-der pressure gauge needle is on the appropriate colorband.ADDITIONAL INSTRUCTIONS1. If in a fresh air environment and the dust cover will notstay on the URC Assembly because air is leaking, cor-rect the condition before using the air mask.2. When filling the URC Assembly in an IDLH atmos-phere and the dust cover will not stay on the URCAssembly because air is leaking:a. Immediately reconnect the quick-fill hose to seal offthe leak and return to fresh air.b. If the hose cannot be reconnected, reach behindand close the cylinder valve. The pressure in the airmask will drop, and the leak will slow down.c. Quickly replace the protective dust cap on the URCAssembly or shoulder mounted quick-fill male fit-ting. This will form a redundant seal.d. Immediately open the cylinder valve and return tofresh air.If the Audi-Larm Alarm begins ringing, the FireHawk M7HUD flashes a single red LED, or the alarm button on theFireHawk M7 Control Module flashes red indicating thatthe pressure in the cylinder has been reduced to 25% ofits maximum working pressure, return to fresh air immedi-ately. The remaining service time must be used for escapeto fresh air.Note: Only persons trained in MSA Maintenance areauthorized to repair or disassemble the URC Assembly.

Use in accordance with this label andMSA apparatus instructions.3. To maintain NIOSH approval, the cylinder must befully charged with respirable air meeting therequirements of the Compressed Gas Associationspecification G-7.1 1989 for Quality VerificationLevel (grade) D air or equivalent specification. Infire service applications, MSA recommends breath-ing air quality in accordance with NFPA 1989.4. Do not use unless the cylinder is filled to the maxi-mum working pressure.5. Do not alter, modify, or substitute any componentswithout approval of the manufacturer.6. Inspect frequently. Maintain according to manufac-turer’s instructions. Repair only by properly trainedpersonnel.Failure to follow these warnings can result in seriouspersonal injury or death.SAFETY PRECAUTIONS FOR MSA SELF-CONTAINEDBREATHING APPARATUS CYLINDERSBreathing apparatus cylinders should be fully rechargedas soon as possible after use.Cylinders should not be stored partially charged:1. If used partially charged, the duration of the air maskis reduced.2. The pressure relief device is only designed to protecta fully charged cylinder from the effects of a fire.For maximum safety, the cylinders should be stored full orat a pressure above ambient but less than 100 psi.Prior to recharging, cylinders must be examined externallyfor evidence of high heat exposure, corrosion, or otherevidence of significant damage.Additional information of value when performing externaland internal inspections of cylinders may be found in thelatest editions of CGA Publication C-6: "Standards forVisual Inspection of Steel Compressed Gas Cylinders",CGA Publication C-6.1: "Standards for Visual Inspectionof High Pressure Aluminum Compressed Gas Cylinders",and/or CGA Publication C-6.2: "Guidelines for VisualInspection and Requalification of Fiber Reinforced HighPressure Cylinders" available form the Compressed GasAssociation, Inc., 1725 Jefferson Davis Highway, Suite1004, Arlington, VA 22202-4102.If there is any doubt about the suitability of the cylinderfor recharge, it should be returned to a certified hydrostat-ic test facility for expert examination and testing.Always check to be sure the retest date is within the pre-scribed period and that the cylinder is properly labeled toindicate its gaseous service. New labels are restricteditems which are not available except through certifiedhydrostatic test facilities.When replacing cylinder valves or after the retesting ofcylinders, make sure the proper cylinder valve, burst disc,and o-ring are installed prior to cylinder recharging.Determine the maximum service pressure of the cylinder.Type 3 AA (steel) cylinders that bear a plus (+) sign afterthe latest retest date may be recharged to a pressure, i.e.a cylinder stamped 3AA2015 with a plus (+) sign after thetest date may be recharged to 2216 psi. (this applies tosteel cylinders only). Steel cylinders without the plus (+)sign stamped after the latest test date must be removedfrom service. All other cylinders which are not 3AA typeshall be filled to the designated service pressure only (asfound on the DOT approval or stamping). For cylindersmanufactured under a U.S. DOT exemption (i.e., DOT-E-#####), the exemption should be consulted and is avail-able from the Associate Administrator for HazardousMaterials Safety, Research and Special ProgramsAdministration, U.S. Department of Transportation, 4007th Street, SW, Washington, D.C. 20590-0001.Appropriately connect the cylinder to the filling systemand refill. Terminate the filling when the pressure reachesthe maximum service pressure and allow the cylinder tocool to room temperature. If necessary, top-off the cylin-der such that the service pressure is attained with thecylinder at a temperature of 70°F. Close the valves on thecylinder and the filling system and remove the cylinder.Apply a leak solution to determine if there is any leakagebetween the cylinder and the valve. If there is no leakage,the cylinder is ready for use.STORAGEDo not store the air mask or spare cylinders within or nearan area where the air mask can or might be exposed toany substances that will or might attack any part of the airmask, causing the air mask to not perform as designedand approved.Prior to storing the air mask in a jumpseat, ensure there isno interference between the air mask and the seat.DO NOT drop the cylinder or bump the valve knob.

FLOW TEST AND OVERHAUL REQUIREMENTSFLOW TEST AND OVERHAUL REQUIREMENTSThe Firehawk Regulator and Audi-Larm Alarm must beflow tested and overhauled at specific time intervals.These Maintenance Procedures must be performed by atrained repairperson or at a certified service center.Contact your MSA sales representative or call the MSACustomer Service Center at 1-877-MSA-3473. They willsupply the information needed to meet these require-ments.Annual flow tests are stated as a requirement in NFPA1852, Standard on Selection, Care, and Maintenance ofOpen-Circuit Self-Contained Breathing Apparatus (SCBA),2002 Edition, which further emphasizes their importance.Although this standard relates to SCBA used in the fireservice, MSA requires that a flow test be performed atleast annually on all fire service and non-fire service SCBAand combination respirators that use a pressure demandregulator.The required replacement/overhaul schedule for MSA airmasks is based on apparatus usage on an individualbasis. The frequency required for air mask overhauldepends upon how often the apparatus is used. MSA airmasks must be overhauled based on the actual level ofusage of the air mask, rather than on time alone.MSA air masks must be flow tested every year using anMSA approved flow test device. The following table sum-marizes MSA’s required frequency for overhaul and flowtesting: An overhaul kit (MSA P/N 10048942) is available.MSA recommends the routine inspection of all elastomericmaterials including, but not limited to those in the VisualInspection and Functional Check section of this manual.A decision to retire apparatus should be based on an airmask’s performance data and whether that data meetsthe specified level of performance as defined in mainte-nance requirements from MSA.*The unit of air mask use is defined as the consumption ofone entire cylinder of air. Example: If three cylinders of airare used, the air mask would be considered to have beenused three times.If an assessment of the air mask’s usage cannot be esti-mated or determined, then the air mask shall be over-hauled every three years.33 TAL 708 (L) Rev. 1 - 10082858CBRN FireHawk Overhaul Regulators and Audi-LarmAverage Air Mask Usage Frequency Alarm Overhaul Frequency Flow Test Frequency1 cylinder per day or greater every 1 year every 3 years every year1 cylinder every other day every 3 years every 8 years every year1 cylinder per week or less every 10 years every 15 years every year

QUICK-FILL SYSTEM OPERATIONQUICK-FILL SYSTEM OPERATIONThe Quick-Fill System may be used for transfill operationsas described in this manual. Only qualified, trained per-sonal Standard Operating Procedures should be devel-oped for use of the Quick-Fill System.PRECAUTIONS FOR USING QUICK-FILL SYSTEM1. The Quick-Fill System can only be used to fillapproved air mask cylinders.2. The Quick-Fill System is not to be used as a "BuddyBreather" such that two users are sharing the air sup-plied by one air mask cylinder simultaneously doing sowill void NIOSH approval.3. The user is responsible for the air supply, which mustmeet the requirements of Compressed GasAssociation Specification ANSI/G-7.1, QualityVerification Level (Grade) D Gaseous Air or better, witha moisture dew point of not greater than -65°F(24ppm water vapor, normal). In fire service applica-tions, MSA recommends breathing air quality in accor-dance with NFPA 1989. Pressures at the inlet of thequick-fill hose must not exceed that of the air mask(2216 psi or 4500 psi).4. Using the 3000 psi URC Assembly to fill cylinders, thecylinder can only be filled to 2216 psi. If the pressureexceeds 2216 psi a relief valve in the URC Assemblywill vent at approximately 2525 psi or as low as 2400psi. A 3000 psi cylinder can only be filled to 3000 psiby using a secondary air supply; the 3000 psi URCAssembly cannot be used for filling a 3000 psi cylin-der.5. The user also is responsible for connecting the quick-fill hose to an appropriate secondary air supply.6. The cylinder must be inspected for damage beforecharging.7. If filling cylinders in fresh air using the Quick-FillSystem topping off the cylinder is recommended afterthe cylinder has cooled from initial fill. Topping off acylinder after it has cooled will ensure proper servicetime.• DO NOT use a 3000 psi air mask with a 2216 psi airmask cylinder.• DO NOT install a Quick-Fill System on a 3000 psiair mask. This combination will not allow the reliefvalve in the 3000 psi URC Assembly to open asdesigned.• DO NOT use the Quick-Fill System as a "BuddyBreather" such that two users are sharing the airsupplied by one approved air mask cylinder simul-taneously; doing so will void NIOSH approval.• DO NOT transfill (be a donor) using a 3000 psi URCAssembly. The 3000 psi URC Assembly has acheck valve that does not allow cylinders to trans-fill (be a donor).•Using the 3000 psi URC Assembly to fill cylinders,the cylinder can only be filled to 2216 psi. If thepressure exceeds 2216 psi a relief valve in the URCAssembly will vent at approximately 2525 psi or aslow as 2400 psi. A 3000 psi cylinder can only befilled to 3000 psi by using a secondary air supply;the 3000 psi URC Assembly can not be used forfilling a 3000 psi cylinder.• DO NOT lubricate the quick-fill fittings.• DO NOT permit oil, grease, or other contaminantsto come in contact with the quick-fill fittings.• The quick-fill hose assemblies and fittings aredesigned to be used with Quality Verification Level(Grade) D or better air as defined by ANSI/CGA G-7.1.TRANSFILLING AIR FROM A SECONDARY AIRSUPPLY. In fire service applications, MSA recom-mends breathing air quality in accordance withNFPA 1989.DO NOT use the Quick-Fill®System, URC Assembly, orExtendAire™ System accessories if there is any possi-bility that the environment contains a CBRN warfareagent. These air mask accessories are not approvedfor use in atmospheres containing CBRN warfareagents.Failure to follow the above warnings can result in seri-ous personal injury or death.The Quick-Fill System must be used only by qualified,trained personnel who have carefully read and understoodthese instructions, cautions, and warnings. NIOSHapprovals of SCBA from MSA are maintained while trans-filling air ONLY if appropriate quick-fill hose assembliesfrom MSA are used. Quick-fill hose assemblies and fit-tings are rated for a maximum working pressure of 4500psi.NIOSH approval is maintained only when using the follow-ing hose assemblies: 485331, 802687, 802688, 802689,802690, and 48332, for filling cylinders in IDLH atmos-pheres.DO NOT use any transfilling hose assembly or fittingsother than those supplied by MSA specifically for theURC Assembly for filling operations. Failure to followthis warning will void NIOSH approval and can resultin serious personal injury or death.A secondary air supply stores compressed breathing airuntil needed to refill air mask air cylinders. When transfill-ing, the secondary air supply pressure must be greaterthan air mask cylinder pressure. Examples of air supplyincludes: cascade air cylinder refilling systems; high pres-35 TAL 708 (L) Rev. 1 - 10082858
QUICK-FILL SYSTEM OPERATIONsure compressor systems with a fixed reservoir; and an airmask air cylinder which is not installed on an air mask.DO NOT use any transfilling hose assembly or fittingsother than those supplied by MSA specifically for theURC Assembly for filling operations.Failure to follow the above warnings can result in seri-ous personal injury or death.FILLING INSTRUCTIONS FOR QUICK-FILL SYSTEM1. To connect the quick-fill hose to the secondary airsupply.a. Turn the air supply on.The following hoses can be used to connect to a sec-ondary air supply.If there are leaks from either female fitting, or alongthe hose, depressurize the hose and correct the prob-lem. Such leakage can result in increased fill time.Failure to follow this warning can result in serious per-sonal injury or death.2. Attach the quick-fill hose to the URC Assembly orshoulder mounted quick-fill fitting.a. Remove the rubber dust cap from the male inlet fit-ting on the URC Assembly or quick-fill fitting. Besure that the cylinder valve is fully opened.b. Remove the rubber dust cap from the female fittingon the quick-fill hose.c. Push the female fitting of the hose onto the male fit-ting of the URC Assembly or quick-fill fitting until itsnaps in place. Pull on the hose to be sure the con-nection is secure. Filling immediately begins whenthe female fitting fully engages with the URCAssembly or quick-fill fitting.d. After approximately 45-60 seconds, the pressurebetween the secondary air supply and the air maskcylinder will be equal.Note: If the secondary air supply does not have a suffi-cient volume of air, the air mask cylinder will not reachmaximum service pressure. After approximately 45-60seconds, pressure between the secondary air supply andthe air mask cylinder will be equal.3. Compare the air mask pressure gauge or ICM Unitreading to the secondary air supply pressure gaugereading. If the readings are the same, pressure isequal.4. To disconnect the quick-fill hose after transfilling, pullthe gray sleeve back. The hose fitting and the male fit-ting will separate. A hiss or pop may be heard as thefittings separate and the high pressure air is sealedoff.5. Immediately install the dust cover on the male fitting.6. The air mask cylinder is ready for service if the cylin-der pressure gauge is on the corresponding colorband.QUICK-FILL SYSTEM EMERGENCY OPERATIONS1. When transfilling in fresh air and the dust cover willnot stay on the male fitting because air is leaking, cor-rect the condition before using the air mask.2. When transfilling in a contaminated atmosphere andthe dust cover will not stay on the male fitting becauseair is leaking:a. Immediately reconnect the quick-fill hose to seal offthe leak and return to fresh air.b. If the hose will not reconnect, reach behind andclose the cylinder valve. Air pressure in the regulatorwill drop, and the leak will slow down.c. Quickly replace the protective dust cap on the malefitting. This will form a redundant seal.d. Open the cylinder valve and return to fresh airimmediately. The dust cover prevents dirt, water,and debris from entering the fitting, and acts as aredundant seal.36TAL 708 (L) Rev. 1 - 10082858Order MSA P/N Description485391 Male stainless steel quick-disconnectwith SAE-10 thread, complete withdust cover (for use as a fitting forcustomized refilling systems).25-FOOT QUICK-FILL HOSESNote: Female quick-disconnect fittingsinclude dust covers.485532 With two female quick-disconnects487906 With a female quick-disconnect on oneend and a SAE-4 fitting on the other.487907 With a female quick-disconnect oneend and a CGA-347 (4500 psig) outleton the other.487908 With a female quick-disconnect on oneend and a CGA-346 (2216 psig) outleton the other.487909 With a female quick-disconnect on oneend and a CGA-347 (4500 psig)coupling nut on the other.487910 With a female quick-connect on oneend and a CGA-346 (2216 psig)coupling nut on the other.
QUICK-FILL SYSTEM OPERATIONTRANSFILLING BETWEEN AIR MASK FROM MSA(EMERGENCY BREATHING SYSTEM)NIOSH DOES NOT approve the use of the URCAssembly to transfer air from the cylinder of one airmask to another air mask. Failure to follow this warn-ing can result in serious personal injury or death.Note: The air mask with the higher pressure reading is thedonor. The air mask with the lower pressure is the receiv-er. Transfilling between users of air mask should be per-formed only during life-threatening emergencies or simu-lated training exercises. Both donor and receiver mustreturn to fresh air immediately following the procedure.DO NOT transfill if the donor's audible alarm is ringingor FireHawk M7 HUD /FireHawk M7 Control Moduleare flashing. Failure to follow this warning can result inshorter escape time to return to fresh air, causing seri-ous personal injury or death.The audible alarm begins ringing and heads-up displaysystem begins flashing to indicate that the pressure in thecylinder has been reduced to 25% of its rated workingpressure. Remaining service time must be used forescape to fresh air. If the donor's audible alarm beginsringing or FireHawk M7 HUD/FireHawk M7 ControlModule begins flashing during transfilling, the donorshould disconnect and preserve his escape time.1. If the donor's alarm is not ringing or FireHawk M7HUD/FireHawk M7 Control Module are not flashingand you have sufficient air to transfill air to a receiver,(greater than 1000 psi for 2216 psi air masks andgreater than 2000 psi for 4500 psi air masks), followthese steps.a. Remove the 3 foot emergency transfill hose from itsprotective pouch.b. Remove the rubber dust cover from both female fit-tings on the quick-fill hose assembly.c. Remove the rubber dust cover from the male Quick-Fill System fitting.d. Push the female fittings on to the male fittings untilthey click in place. Pull on the hose to be sure itsnapped in place.If serious leakage is noticed from either of the twofemale fittings, or anywhere along the hose, discon-nect the female fittings and return to fresh air immedi-ately. Failure to follow this warning can result in seri-ous personal injury or death.e. After approximately 30-60 seconds, pressurebetween the air mask cylinders will be equal.f. Disconnect the quick-fill hose from the air mask bypulling the gray sleeve back on both ends. A hiss orpop may be heard as the fittings separate and thehigh pressure air is sealed off.g. Immediately install the dust cover on the quick-fillmale fitting. The dust cover prevents dirt, water, anddebris from entering the fitting, and acts as a redun-dant seal.QUICK-FILL SYSTEM STORAGE2. Preparing the Quick-Fill System for storage:a. Press in on the center of the quick-disconnect dustcap to release any pressure in the quick-fill hose.b. Roll up the hose and place it in its protective pouch.Note: Only persons trained in MSA Maintenance areauthorized to repair or disassemble the Quick-Fill System.If repairs are required, contact your nearest MSA office.Call 1-800-MSA-2222.37 TAL 708 (L) Rev. 1 - 10082858

EXTENDAIRE™ SYSTEMINSTRUCTIONS FOR USEGENERAL INFORMATIONTwo air masks equipped with an ExtendAire System canshare a common air supply during emergency escape.Users can couple the Firehawk Second Stage Regulatorfrom one user to the intermediate pressure manifold of theother user. Both users will receive intermediate pressureair from the donor's first stage regulator and cylinder. Theduration of the remaining air supply will be reduced by atleast half.The SCBA is approved by NIOSH without inter-connectingtwo users to one apparatus. NIOSH does not certify“buddy breathers”. Therefore, the attachment of thereceiver's regulator to the donor's apparatus voids theNIOSH approval for both air masks.Air Hose: When used as a combination apparatus, thedevice shall be supplied with respirable air through airsupply hose with a minimum length of 8 feet and maxi-mum length of 300 feet within the pressure range of 85-90psi. A maximum of 12 sections of straight or uncoiled airsupply hose may be used in making up the workinglength of hose. When using coiled hose, a maximum ofsix sections may be used and each section is consideredto be 50 feet long. Hose sections vary from 8 feet to 100feet lengths. The air-line connection to the apparatus is tobe made through approved quick-disconnects only. Thepurity of the air supply is the responsibility of the user. Therespirator is approved only when the air supplied meetsthe requirements of the Compressed Gas AssociationSpecification G-7. 1989 quality verification level (Grade) Dfor Gaseous Air.Use this emergency escape breathing system for lifethreatening emergencies and simulated training exer-cises only. All other adequate means of escape mustbe considered before using this device.• During use the air supply, and consequently theservice time, is reduced approximately in half.Before connecting two users make sure the airsupply is sufficient for both users to escape; other-wise do not use the system.• DO NOT use the system if the donor's audiblealarm is ringing.• The NIOSH Approval for both apparatus are voidwhen this device is used, due to the difficulty inmaneuvering during escape. Exercise extreme carewhile connected together. Mobility and range ofmotion will be limited when donor's and receiver'sair masks are connected.• Maintain slack in the air lines during maneuveringand while connected together. DO NOT pull on thehoses. Pulling on the rescue hose or the intermedi-ate pressure hose could separate hoses from fit-tings resulting in air leaks.If the above measures cannot be followed or to pro-vide greater escape protection, use the Quick-FillSystem. It maintains approval while transfilling anddoes not exhibit the above hazards.DO NOT use the Quick-Fill®System, URC Assembly, orExtendAire™ System accessories if there is any possi-bility that the environment contains a CBRN warfareagent. These air mask accessories are not approvedfor use in atmospheres containing CBRN warfareagents.Failure to follow this warning can result in serious per-sonal injury or death.EMERGENCY ESCAPE BREATHING SYSTEM:INSTRUCTIONS FOR USEThe ExtendAire System uses Snap-Tite quick-discon-nects.The Snap-Tite quick-disconnect has two significant fea-tures.1. It is single action to connect. The coupler is pushedfirmly over the plug to engage.2. It is a locking type that requires two actions to discon-nect.a. Push the two sides of the quick-disconnect towardseach other. (The plug should advance into the cou-pler end approximately 1/8".)b. Slide the coupler’s outer sleeve away from the plug.Pull the plug out of the coupler. Ensure that thequick-disconnect plug on the manifold block is pro-tected by the dust cap.DO NOT install or attempt to use any hose assemblyor fitting other than those supplied by MSA for theExtendAire System. Failure to follow this warning canresult in serious personal injury or death.PREPARATION FOR USEBEFORE ENTERING A TOXIC ATMOSPHERE1. Don the apparatus as described in the donning sec-tion.2. Ensure proper engagement of the Snap-Tite quick-dis-connect coupling on the intermediate pressure hose(at the manifold tee).39 TAL 708 (L) Rev. 1 - 10082858
EXTENDAIRE SYSTEMPROVIDING OR OBTAINING EMERGENCY BREATHINGSUPPORTFollow these procedures to connect and disconnectthe emergency escape breathing system hardware.Individual development of operating procedures andsufficient training is required to use this equipment inactual emergency conditions. Failure to follow thiswarning can result in serious personal injury or death.Hose Connection Procedure1. Remove the dust cap from the quick-disconnect onthe donor's intermediate pressure manifold block.2. Disconnect the receiver's second stage regulator hosefrom their intermediate pressure manifold block bydisengaging the Snap-Tite quick-disconnect fitting.3. Connect the receiver's second stage regulator hose tothe donor's manifold block.a. Push the socket of the receiver's hose firmly overthe plug on the donor's manifold.b. Check that the hose is properly routed and not tan-gled with any other part of the apparatus (i.e. neckstrap, chest strap, etc.)c. Check for full engagement by pulling at the quick-disconnect to assure that the socket does not sepa-rate from the plug. The apparatus of the donor willsupply air for emergency escape of the two individ-uals. The duration of the remaining air supply will (atleast) be reduced in half.4. Upon reaching a safe, non-toxic atmosphere, a stag-ing area or performing other emergency egress proce-dures, uncouple the receiver's hose at the quick-dis-connect.5. Replace the dust cap on the Snap-Tite plug.The receiver's facepiece or regulator must beremoved upon disconnection from the donor's air sup-ply. Failure to follow this warning can result in seriouspersonal injury or death from suffocation.40TAL 708 (L) Rev. 1 - 10082858
APPENDIXFIREHAWK M7 TELEMETRY MODULEThe FireHawk M7 Telemetry Module is designed to allowthe air mask to communicate with a remote base stationwhile in use. The FireHawk M7 Air Mask with FireHawkM7 Telemetry Module installed will transmit vital statisticssuch as cylinder pressure, temperature alarm (if thermalalarm is enabled), service time remaining, and PASS alarmto the base station. The base station also has the abilityto send an evacuation command to the air mask. TheFireHawk M7 Telemetry Module uses a special version ofthe FireHawk M7 Control Module and FireHawk M7 PowerModule.All basic functions of the air mask are the same as thosedescribed in the During Use section of this manual exceptfor the following differences:•Turning the FireHawk M7 Control Module On: Whenthe FireHawk M7 Control Module is activated in thepresence of a remote base station, the air mask auto-matically begins to log on to that base station. Whenthe air mask is successfully logged on to the base sta-tion, a radio link indicator will appear on the display ofthe FireHawk M7 Control Module.•Evacuation Signal: The air mask has the ability toreceive an evacuation signal from the remote basestation after it has been successfully logged on to thebase station. When an evacuation signal has beensent by the base station, the “running man” icon willappear, and flash, on the display of the FireHawk M7Control Module and a unique audible alarm will beemitted from the FireHawk M7 Power Module. Theevacuation signal must be manually confirmed by theuser by pressing the reset button (yellow) button twicewithin approximately one second. This confirms theevacuation signal by sending a confirmation signalback to the base station. Once the evacuation signalhas been manually confirmed by the user, the “runningman” icon will stop flashing and remain on the displayuntil the FireHawk M7 Control Module has beenturned off.•PASS Alarm: The PASS alarm will sound and functionnormally with the FireHawk M7 Telemetry Module.When the air mask emits a full PASS alarm, a signal isautomatically sent to the base station to alert IncidentCommand.•Thermal Alarm: When the air mask is exposed totemperature conditions that warrant a thermal alarm, asignal is automatically sent to the base station to alertIncident Command.•Low Battery: When the FireHawk M7 Power Modulereaches a low battery condition, a signal is automati-cally sent to the base station to alert IncidentCommand. A signal is not sent to the base station ifthe FireHawk M7 HUD has a low battery condition.•Data Log: The data logging feature of the FireHawkM7 Control Module logs the status of the radio link tothe base station as well as any evacuation signals thatthe air mask has received.•Radio Link Indicator: The FireHawk M7 ControlModule has a radio link indicator located in the upperleft portion of the display. When this icon is displayed,the air mask is logged on to a base station and withinrange. When the radio link indictor is not shown, theFireHawk M7 Control Module has not been logged onto a base station or is out of the range of the basestation.•Turning the FireHawk M7 Control Module Off: Toturn the FireHawk M7 Control Module off, press thereset button (yellow) twice within approximately onesecond. If the air mask is logged on to the base sta-tion, there will be a delay between the two presses ofthe reset button (yellow) and the actual shutdown ofthe device. Before the FireHawk M7 Control Modulecompletely turns off, the base station must remove theair mask from its registry. This causes the slight delaybetween pressing the reset button (yellow) and theactual shutdown of the device.ID Tag (PN 10083875), for use with FireHawk M7Telemetry ModuleWhen the FireHawk M7 Telemetry Module is used with theFireHawk M7 Air Mask, an ID Tag is used to assign a fire-fighter’s name to the air mask. The name assigned to theair mask will be displayed for that air mask on the basestation SCBA monitoring software. The name ID Tag mustbe scanned into the FireHawk M7 Control Module at thestart of each shift (every 24 hours by default).Note: The FireHawk M7 Interface Software can be usedto change this default to allow a name ID to be perma-nently assigned to the air mask until a new name ID Taghas been scanned.A team ID Tag can also be used to assign a team/truckand position to the air mask. If a team ID Tag has beenscanned into the FireHawk M7 Control Module but aname ID Tag has not been scanned, the team ID will bedisplayed on the SCBA monitoring software to provideaccountability even if the firefighter forgot to scan thename ID Tag. Once a team ID Tag has been scanned intothe FireHawk M7 Control Module, the team ID will remainwith the air mask until another team ID Tag has beenscanned. If a team ID has not been assigned to the airmask, the FireHawk M7 Control Module serial number willbe displayed as the firefighter’s ID when logged onto thebase station.A base station ID can be used to assign a specific basestation ID to an air mask. When more than one base sta-tion is present and actively monitoring at an incident, anair mask with an assigned base station will search for thepreferred base station first to log on to, and if it does notfind the assigned base station within 20 seconds, it willsearch for the first available base station and log on to it.If a base station ID has not been assigned to the air mask,it will log on to the first base station that it finds once the41 TAL 708 (L) Rev. 1 - 10082858
APPENDIXunit has been turned on. Once a base station ID tag hasbeen scanned into the FireHawk M7 Control Module, thisbase station ID will remain with the air mask until anotherbase station ID tag has been scanned. The ID Tag has aspace for the user to place a label in which the ID infor-mation can be written on the outside of the ID Tag foreasy identification. This space is located on the side ofthe ID Tag opposite the approval label.Before using the ID tag, inspect for damage or cracks inthe case. If damage is found, discard and replace the IDtag.Scanning the ID Tag into the FireHawk M7 ControlModuleNote: The FireHawk M7 Control Module must be turnedoff to scan the ID Tag.Prior to pressurization of the air mask and during inspec-tion, the user can “tag in” by depressing and holding thetop mode button (green) until the word “data” appears inthe display. The FireHawk M7 Power Module will sound asingle beep when the FireHawk M7 Control Module enters“data” mode. While “data” is displayed, hold the ID tagas shown.Correct ID Tag OrientationThe FireHawk M7 Power Module will sound a single beepconfirming that the ID data has been read and the word“data” will disappear from the FireHawk M7 ControlModule display. If the word “data” disappears from theFireHawk M7 Control Module display before the ID Taghas been read, the FireHawk M7 Control Module hastimed out and the top mode button (green) must bedepressed and held again until “data” reappears.The most recent ID Tag data that is stored in the FireHawkM7 Control Module will be used as the identification forthe air mask on the base station PC screen. If no ID Tagdata has been assigned to the air mask, the FireHawk M7Control Module serial number will be used as its identifi-cation on the base station PC screen.The ID tag is not designed to be taken into a fire. TheID tag can also be used as an accountability tag.Using the Base Station with the FireHawk M7Telemetry ModuleThe FireHawk M7 Telemetry Module is designed to workin conjunction with a remote base station unit. This basestation unit must be connected to a personal computer orlaptop before use. Refer to the Accountability SystemSoftware instructions (PN 10068929) for more information.Follow the PC or notebook computer manufacturer’srecommendations for exposure to environmental con-ditions to prevent damage to the system. Failure to doso may cause system failure and the loss of monitor-ing capability on the PC or notebook computer.Using the M7 Firehawk Air Mask with FireHawk M7Telemetry ModuleLogging the Air Mask on to the Base Station1. Turn on the FireHawk M7 Control Module on by open-ing the cylinder valve or by pressing and holding thealarm button.2. A helmet icon representing the user of the air maskwill appear on the base station PC screen.3. When the base station has established contact withthe air mask and all initial information has beenobtained, the signal strength indicator will appear inthe upper left corner of the FireHawk M7 ControlModule display.4. Periodically check the status of the signal strengthindicator on the display of the FireHawk M7 ControlModule. If the signal strength indicator shows no bars,this means that the air mask is out of range from thebase station. If this occurs, the signal strength indica-tor will show 4 bars when the air mask returns withinrange of the base station.If the signal strength indicator does not appear on theFireHawk M7 Control Module display, the base stationhas not logged the unit on and can not monitor thestatus of that firefighter.Logging the Air Mask off of the Base Station1. Once the user has returned to fresh air the FireHawkM7 Control Module may be turned off.2. Close the cylinder valve and purge the remaining airfrom the system using the Firehawk Regulator bypass.When the pressure falls below 200 psi, turn theFireHawk M7 Control Module off (sleep mode) bypressing the reset button twice in approximately onesecond. (When the air mask is logged on to a basestation, there may be a delay between the two rapidpresses of the reset button and the actual shutdownof the FireHawk M7 Control Module. Before theFireHawk M7 Control Module completely turns off, thebase station must log off the air mask and send out afinal confirmation signal.Evacuation SignalIf the air mask is logged on to the base station, the basestation will have the ability to send an evacuation signal tothe air mask.
