In addition, there are bothphysiological and psychological limitations which should beconsidered before using SCBA. They include, but are not lim-ited to:* Emphysema* Chronic obstructive pulmonary disease* Bronchial asthma* X-ray evidence of pneumonia* Evidence of reduced pulmonary function* Coronary artery disease* Severe or progressive hypertension* Epilepsy (grand mal or petit mal)* Pernicious anemia* Diabetes (insipidus or mellitus)* Breathing difficulties when wearing an SCBA* Claustrophobia or anxiety when wearing an SCBA* Abnormal EKG results from resting or stress tests* Punctured or ruptured ear drumWORKING TEMPERATURES: The VIKING SCBA is ap-proved for respiratory protection during entry into or escapefrom oxygen deficient atmospheres, gases, and vapors attemperatures above -25°F. When used below freezing, caremust be exercised to prevent moisture from entering the de-mand exhalation valve. The facemask should remain on thedocking hook when not in use. On the AirSwitch model, theslide should be stored in the up position when not in use. Forthe RDV demand valve, the RDV should be stored on thedocking station found on the waistbelt. This includes whencylinders are being changed.DURATION OF USE: Although the VIKING has been ap-proved as either a 30-minute, 45-minute, or 60-minute breath-ing apparatus, the wearer’s varying work rate, physical condi-tion and other factors could substantially shorten the actualusable duration of the unit.SCBA LIMITATIONS: An SCBA can only protect the wear-er’s respiratory system. Other protection may be necessaryto avoid contamination through skin absorption. If these typesof materials are suspected, an effective full-body covering ofimpermeable material must be worn with the SCBA. A univer-sal Level A HazMat suit is available for the VIKING SCBAfrom HazMat suit manufacturers.FACIAL HAIR: Facial hair or any other items which may in-terfere with the facemask-to-face seal, including the nosecup,or the operation of the exhalation valve, must not be allowed.These include beards, sideburns, mustaches, bangs, headcoverings, or anything else that may interfere with the correctseal of the facemask and/or nosecup to the face. See NFPA1500 and ANSI Z88.2EYE WEAR: Eye glasses shall not be used when the temple

COPYRIGHT 2007 AVON - ISI 3All Viking Z SEVEN SCBA are NIOSH CBRN agent approved,NIOSH approved and NFPA 1981Standard, 2007 Editioncompliant. The Viking Z SEVEN features a heads-up display(HUD) that monitors cylinder pressure and an emergency RICconnector that is used to refill the air of a down fire fighter.The Viking Z SEVEN model has VAS (Voice AmplificationSystem) and data logging as standard features. Additionaloptions of the Z SEVEN model include radio interface, voiceactivated communications, integrated PASS, buddy breatherand airline. All Vikings are available with light weight carboncylinders in 30, 45 or 60 minute rated durations.The AVON-ISI Viking Z SEVEN is a self-contained, open-cir-cuit, compressed-air breathing apparatus, which is approvedby the National Institute of Occupational Safety and Health(NIOSH) and certified compliant to NFPA 1981Standard onOpen-Circuit Self-Contained Breathing Apparatus for Fire andEmergency Service, 2007 Edition. Positive pressure insidethe facemask, both during inhalation and exhalation, ensuresthat any leakage due to improper fit or component failure willbe an outward flow of air.The Viking Z SEVEN SCBA consists of several major compo-nents described in the following paragraphs.1.1 FACEMASKThe AVON-ISI full facemaskassembly has a two point pull-forward Nomex net harnesswith an optically-corrected,double curve high-impactpolycarbonate visor. The vi-sor’s scratch-resistant coatingconforms to NFPA standards.The interior of the visor has apermanent anti-fog coating.The facemask standard sealis high-strength butyl blendand has a patented blendedshape which fits the firefight-er's helmet without readjust-ment. A standard black inner-mask nosecup reduces dead-airspace and CO2 buildup. The facemask has CBRN labels af-fixed at both lower corners of the visor.An in-mask HUD is mounted to the inner-mask nosecup. Themask display includes five LEDs: red = ¼ full, yellow = ½ full,1st green = ¾ full, 2nd green = full, and the last elevated yel-low = low battery indicator. The HUD indicates remaining cyl-inder pressure and provides the primary end-of-service time1.0 DESCRIPTION OF VIKING Z SEVEN SCBAalarm. The HUD can also provide additional status indicatorsdepending upon the options ordered.1.2 AIRSWITCH® REGULATORThe patented AirSwitch second stage regulator is incorporat-ed into the facemask and combines the demand and exhala-tion valves to greatly reduce breathing resistance. This alsoallows for a longer duration of cylinder use. A speech dia-phragm provides excellent clarity and voice reproductionwhile incorporating the exhalation valve.The AirSwitch features a fresh air mode which allows usersto go from cylinder air to outside air by depressing the twocontrol slide tabs inward and then raising the slide upwardsfully. Push down for cylinder or supplied air. The AirSwitchshould stay open prior to donning and doffing of the VIKINGSCBA. The AirSwitch is made of high performance engi-neered plastics and incorporates a true manual bypass con-trol for emergency use.Down for supplied airUp for ambient air• This approval applies only when the device is supplied withrespirable breathing air through 6 to 300 feet of hose at airpressures between 80 to 120 pounds per square inch gauge orfrom self contained air supply.NOTE: Viking CBRN SCBAs are not approved for supplied airuse in confirmed or potential CBRN environments.• If the supplied air fails, open the cylinder valve, unplug supply airand proceed to fresh air immediately.• Use adequate skin protection when worn in gases and vaporsthat poison by absorption (example: hydrocyanic-acid gas).yellow(low battery)greenyellowredS- SPECIAL OR CRITICAL USER’S INSTRUCTIONS, CONTINUED
COPYRIGHT 2007 AVON - ISI41.3 REMOVABLE DEMAND VALVE (RDV)REGULATORThe Viking RDVregulator is a maskmounted second stageregulator with a 1/8thturn positive lockingmechanism, whichsecures into thefacemask. The RDVfacemask incorporatesa speech diaphragmthat provides excellentspeech clarity evenunder heavy breathing.The standard HUD is still inside the facemask with themicrophone. Docking the RDV on the facemask also alignsthe electronic connection in one simple step. After removingthe RDV from the facemask, it should be stored in the dockingstation on the waistbelt strap to keep free of dirt and debris.1.4 FIRST STAGE PRESSURE REDUCERAir leaves the cylinder, pass-es through a sintered bronzefilter in the handwheel elbowassembly, and then contin-ues on through a high pres-sure flexible hose to the first-stage pressure reducerwhere it is reduced to ap-proximately 125 psi. The re-ducer is a simple piston typethat requires no adjustmentand incorporates an automat-ic, self-seating pressure relief valve to protect the low-pres-sure components downstream. It is made of high quality alu-minum, and is securely mounted inside the backframe assem-bly.1.5 END-OF-SERVICE INDICATORSThe primary End-of-Service indica-tor is incorporated into the HUD.The display will flash a single redLED at 23% to 27% of rated cylin-der pressure per NIOSH require-ments. The primary end-of-servicealarm meets NFPA 1981, 2007Edition requirements.The secondary End-of-Serviceindicator is a bell mounted in-side the backframe which is setto activate at 23-27% of ratedcylinder pressure per NIOSHand NFPA requirements.1.6 BACKFRAME AND HARNESSThe backframe and harness assembly utilize ergonomic de-sign principles to produce a com-fortable, low profile unit that evenlydistributes the SCBA weight be-tween the wearer’s hips and shoul-ders.The unique double-wall backframeof the Viking protects major airlines,the first stage reducer, bell alarmand digital components. A quick-re-lease cylinder band fits a widerange of cylinders with an infinitelyadjustable latch to ensure a tight fit-ting cylinder.The harness material is NFPA com-pliant, custom woven KEVLAR®.The upper harness has very resilient foam rubber padding foradded comfort and PBI/KEVLAR cover for maximum durabili-ty and protection. There is an optional backframe plate thatcan be ordered (p/n 099038) to reinforce the upper harnessstraps for departments that do heavy simulation training offire fighter rescue operations. A lower lumbar pad is standardfor added comfort and support.1.7 CONTROL CONSOLEThe control console and PASS assembly communicate witheach other through a wirelessnetwork. The network uses a dis-creet frequency that eliminatesnoise and resistance to other ra-dio frequencies. This wirelessnetwork joins the Control Con-sole and PASS assembly to-gether, allowing for constant datato be exchanged. The PASS mo-tion sensor on the Z SEVEN is inthe Control Console. When mo-tion is detected, the PASS will re-set for 25 seconds.NOTE: Only Duracell MN 1500 or Energizer E91 1.5 volt AAbatteries are to be used with the battery packs. Besure to place batteries in the direction as indicatedon the battery compartment in order to prolong bat-tery and fuse life. Use of other batteries will void theintrinsic safety approval.red end of servicealarm
COPYRIGHT 2007 AVON - ISI 51.7.1 SERVICING CYLINDER VALVEAfter each use, and prior to recharging, the cylinder valve mustbe inspected for damage. If a new valve is replacing a valvethat was damaged in use, it will be necessary to hydrotest thecylinder before installing the new valve.NOTE: Any maintenance on the valve that requiresdisassembly should be conducted by an AVON-ISIAuthorized personnel or an AVON-ISI technician whois well trained in the hazards of high pressureequipment. Never attempt to remove the valve fromthe cylinder while there is any pressure in thecylinder. Open the valve completely to be sure it isempty. If the gauge shows pressure but you think thecylinder is empty, contact the AVON-ISI factory foradvice by calling 888-474-7233.NOTE: Prior to revalving a cylinder, you must perform thefollowing inspection:• Remove o-ring from sealing threads on cylindervalve.• Clean threads to remove any lubricant.• Inspect the cylinder threads, ensuring the threadsare not distorted or cracked.• Inspect the valve threads, ensuring the threads arenot distorted or cracked.• Install new o-ring.If any threads are distorted or cracked, the parts shouldbe tagged “Out of Service” and be condemned.1.8 CYLINDER AND VALVE ASSEMBLYA range of cylinder types and capacities are available on theVIKING 2216 psi and 4500 psi models. (Please see the tablein Section 1.10 for specifics.)The cylinder valve is of aluminum construction with apermanent teflon coating. The valve outlet is a standardCGA-346 fitting on 2216 psi cylinders, and a standard CGA-347 fitting on 4500 psi cylinders. Each valve has a dual-reading pressure gauge. Valve protection is provided by anelastomeric bumper. See section 2.3.2 for inspection prior touse.The valve can be used with AVON- ISI cylinder assembliesbetween 23 cubic feet and 87 cubic feel. The cylinder valvehas a burst disc type safety device to protect the cylinderfrom over pressurization.The cylinders and valve are matched according to pressure.The maximum pressure on the gauge built into the cylindervalve should match the pressure rating on the cylinder. A2216 psi valve will not fit into a 4500 psi cylinder and viceversa. For easy recognition AVON- ISI has made 4500 psihandwheels red and a 2216 psi handwheel black. (Exception:Every Viking Z SEVEN has a RIC fitting attached near thehandwheel that allows a downed fire fighter to have theircylinder charged from an outside source. NFPA 1981, 2007Edition requires this fitting on all SCBA’s manufactured for firefighters. The RIC fitting is compatible with othermanufacturers and is intended as an emergency refill only.The RIC fitting will not work as a transfill system between twoSCBA’s. There is a dust cap cover for the fitting to preventdebris on the fitting. See section 4.7 for detailed workinginstructions.1.10 Mounting SCBAIf you mount the Viking Z Seven in a jump seat or mountingsystem of any vehicle, you must ensure that the mounting de-vice meets NFPA standards and that the mounting devicedoes not interfere with components such as cylinder, thatcould cause damage or cause sudden loss of cylinder pres-sure.all Viking ST models will have black handwheels no matterwhat the pressure rating of the cylinder.)The cylinder valve has two sets of male threads - one willscrew into the cylinder and the other is used to attach to thepneumatics of the SCBA. The latter threads are referred to asCGA (Compressed Gas Association) threads. It is important toprotect the CGA threads so that the pneumatics will alwaysscrew onto them without doing damage to the handwheel onthe pneumatics.If any threads are distorted or cracked, the parts shouldbe tagged “Out of Service” and be condemned.HANDLING PRECAUTIONS:NEVER LIFT OR CARRY UNIT BY THE HIGH PRESSUREHOSES. IF A HIGH PRESSURE HOSE BECOMES KINKEDOR OTHERWISE DAMAGED, IT SHOULD BE REPLACED.CHECK FOR DAMAGE NEXT TO THE METAL ENDS OFTHE HOSE.1.9 RAPID INTERVENTION CREW (RIC) FITTING

Review section 9 fordetailed instructions of available options.4.1 READING THE HEADS-UP DISPLAY (HUD)4.1.1 The HUD includes five LED lights: two green, twoyellow and one red. Each of the 4 LEDs in a rowrepresents a quarter increment of the rated servicepressure. As cylinder pressure decreases, the LEDschange status. At full rated service pressure, all fourLEDs are on. As cylinder pressure drops below full,the top green LED begins blinking. At ¾ rated servicepressure, the top green LED turns off and the nextgreen LED begins blinking. At ½ rated servicepressure, the second green LED turns off and theyellow LED begins blinking. At ¼ rated servicepressure, the yellow LED turns off, and the red LEDblinks at a fast rate. The top offset yellow light is a lowbattery indicator. Refer to the following table for moreinformation regarding mask pressure display interpre-tation.3.2.5 RECHECK CYLINDER PRESSURE: Check theheads-up display. Four lights should be "on". Thetop green light may be flashing, indicating at least7/8th full. Verify the analog gauge is at or above the7/8th level.3.2.6 BATTERY CHECK: The top yellow LED will be "ON"when the control console batteries are low. If thepass batteries are low, displays red LED on consoleand the pass alarm will chirp every 15 seconds. TheLED on the console will be red. If the SCBA shows alow battery warning, replace batteries in accordancewith section 8.3.3.2.7 VAS CHECK3.2.7.1 Turn SCBA on by either opening cylinder valve or bymanually depressing on buttons.3.2.7.2 Hold mask up to face and speak into mask.3.2.7.3 Listen to speech emanating from VAS speaker andensure its intelligibility and function.WARNINGSIF ANY OF THE ABOVE CHECKS FAIL, DO NOT PRO-CEED.

Redness of skin4.7 RIC FITTING PROCEDURESThe RIC fitting is designed as an emergency refill only andhas specific uses and functions per NFPA 1981, 2007Edition. The system can only be used to fill approved SCBAcylinders. The RIC fitting has an internal balanced pistonthat prevents over pressurization of a cylinder. A check valveprevents fire fighters from transfilling SCBA’s, or any otherunapproved use on AVON-ISI products. Users will be able tohave a 4500 psi cylinder as a supplied air system andconnect to a 2216 psi SCBA RIC connector. Air will stopflowing automatically from the high-pressure cylinder whenthe correct pressure (2216 or 4500) is achieved.To recharge a cylinder on a downed fire fighter, an approvedcharging hose must be used. The AVON-ISI Rescuer usesthe following approved hoses: a 3 foot RIC Charging Hose(p/n 162051), a 6 foot RIC Charging Hose (p/n 162052), or a10 foot RIC Charging Hose (p/n 162053) for filling thecylinder in IDLH atmospheres.4.7.1 Open cylinder valve of supplied air and remove thedust cap from the RIC charging hose. Inspect thefire fighters cylinder for damage and ensure that thecylinder valve is fully opened.WARNINGCYLINDERS THAT ARE DAMAGED MAY SUDDENLYRUPTURE IF CHARGED.4.7.2 Remove dust cap from the RIC fitting on the SCBAand attach the RIC charging hose to it. Listen forleaks on the SCBA that is being filled. Rechargingwill take between 2-4 minutes, depending on thecylinder duration and pressure. When the pressuresequalize, unplug the charging hose from the SCBAand replace dust covers and exit. During aprolonged rescue, users can leave the supplied aircylinder plugged into the downed fire fighter’sSCBA, adding additional duration to the cylinder.NOTE: If any time during charging, a leak is detected;discontinue charging and exit IDLH atmosphereimmediately.NOTE: In a non-emergency situation, cylinders shall not berefilled through the RIC.4.7.3 Once clear of an IDLH atmosphere, close the cylindervalve on the RIC charging hose. Ensure there is nodebris in the dust cap prior to pushing on the dustcap. The bottom of the dust cap reads "press torelieve". With dust cap in place, push down on dustcap on a hard surface to bleed pressure.4.7.4 Top off cylinder attached to charging hose before nextuse to ensure proper service time.IMPORTANTDO NOT REMOVE ANY EQUIPMENT UNTIL YOU ARECLEAR OF AN IDLH ATMOSPHERE.4.8 PASSThe wireless network between the PASS and control consolemust always be updating. You must verify on start-up that theconsole's LEDs are green. If console LED flashes red for morethan 30 seconds, the PASS will go into alarm and will not turnoff until backframe batteries are removed. Usually the cause islow battery from either power source that never was changed.bottom of RICcharging hose

COPYRIGHT 2007 AVON - ISI 199.1.2 COMMUNICATIONSThe Viking Z SEVEN is available with several communicationoptions. The microphone is a standard feature and is mountedinside the facemask on the nosecup. It offers excellent speechclarity. All communications have a noise suppressor to reduceexhaled breathing air noise.Note: The Viking Z SEVEN electronics and pneumaticsturn on automatically when the cylinder valve isopened. The SCBA electronics can be turned onmanually by depressing the lower two ON/OFF but-tons on the console.9.1.2.1 VOICE AMPLIFICATION SYSTEM (VAS)The VAS uses a sealed, in-mask microphone tocapture the user's voice, amplifies it, and thenbroadcasts it from the speaker on the console. Thisis particularly useful in communicating with otherpeople nearby when the SCBA is in the positivepressure mode. VAS is preset to be voice acti-vated. You must speak slightly louder than normalto activate VAS.The VAS is on standby mode whenever the SCBAcylinder is opened. When speech is sensed, it turnson the amplifier and sends it to the console. Shortlyafter speech ends, the amplifier goes back intostandby mode.VAS can be turned off if the user desires. To turnoff the VAS, the cylinder valve must be opened andpower activated to the control console. To disablethe VAS, push inward on the Function key andpush the PTT button. An audible chirp should beheard. VAS is now in the off setting. To turn VASback on, repeat the above function. When the Vi-king SCBA is powered down, the system will defautto VAS "on" when the electronics are activiated. 9.1.2.2 VOICE ACTIVATION LEVELSThe microphone activation level is adjustable for in-dividual preference. Push the Shift button on thefront of the console inward and hold. The HUDfacemask display will flash the preset point of thevoice activation level. To change the settings, whileholding the Shift key, push the PTT button once.This will raise the activation point. Continue to pushthe PTT to your personal preference. Release theShift key to set activation level. To go from Level 4to Level 1, hold the Shift key inward and push thePTT button again.There are ten set points for the voice activationlevel. Level 1 is the most sensitive activation pointup to a Level 10 being the least sensitive activationpoint. Each level will be displayed a specific num-ber of HUD light(s) that activate. With each in-creased level, less inhalation breathing noise isheard, but voice must be raised higher to begin am-plification in order for the microphone to detectspeach. The settings are a follows:Level HUD LED Pattern1 Flashing Red2 Red, Flashing Yellow3 Red, Yellow, Flashing Green 4 Red, Yellow, Green, Flashing Green 5 Red, Yellow, Green, Green 6 Flashing Red, Low bat 7 Red, Flashing Yellow, Low Bat 8 Red, Yellow, Flashing Green, Low Bat 9 Red, Yellow, Green, Flashing Green, Low Bat 10 Red, Yellow, Green, Green, Low Bat1 2 3 4 5 6 7 8 9 109.1.2.3 RADIO INTERFACEWhen the Z SEVEN is equipped with radio interface, ithas the ability to significantly decrease the backgroundnoise of outgoing transmissions. This is due to theplacement of the sealed microphone inside thenosecup, which is well insulated from ambient noise. In-coming transmissions are broadcast from the consolespeaker. On units designed for use by law enforcement,incoming transmissions are recieved through an op-tional ear speaker.A separate radio lead is required to integrate the con-sole to the radio. The radio connects to the interfacecable on the lower control console..There are two ways to key the radio and transmit: in themanual mode, press and hold the Push-To-Talk button(PTT) on the side of the console. As an indication thatthe PTT button has been pressed, the right LED indica-tor light turns green on in the console display and asolid green light on the HUD. If VAS is installed withRadio Interface, the VAS is disabled whenever the radiois keyed.To activate the hands free VOX mode, press and re-lease the PTT button twice within one second (doubleclick). A flashing red light will illuminate on the controlconsole display. In this mode, the radio is keyed auto-matically whenever the SCBA senses user speech. TheHUD will illuminate only the top green (full) light when-ever user speech has keyed the radio. When speechhas ended, the unit automatically turns off the amplifierto conserve the battery and the HUD again monitorscylinder pressure. To end the hands free mode, doubleclick the PTT button again.9.1.3 Viking Z SEVEN PASSThe PASS on the Viking Z Seven is an NFPA 1982compliant Personal Alert Safety System (PASS) thatis integrated with the SCBA and with the otherAmount breathingnoise amplified

It requires no adjustments.The PASS is automatically activated when thecylinder is opened or may be manually turned on bypushing both "ON/OFF" side buttons on the consolesimultaneously. Once turned on, it normally operatesin the “sensing” mode where it looks for motion at theconsole.9.1.3.1 PASS Operating Instructions WARNINGALWAYS TEST THE PASS PRIOR TO ENTRY INTOA HAZARDOUS ATMOSPHERE. IF THE LOWBATTERY WARNING SIGNAL ACTIVATES,INSTALL NEW BATTERIES AFTER USE OR PRIORTO USING THE VIKING Z SEVEN. THE CONTROLCONSOLE WITH PASS SHOULD BE POSITIONEDFLAT AGAINST THE SHOULDER STRAP.When the PASS is turned on, a chirp will be heard onthe control console speaker, followed by a chirp fromthe PASS alarm on the backpack. Additionally, the leftLED users prospective on the console display willslowly flash green when PASS is on. When there is alack of motion sensed at the control console for over25 seconds, the PASS will go into pre-alarm andsound an audible warning that will progressively getlouder until the PASS goes into full alarm. While inpre-alarm, the red (¼ full) and top green (full) lightson the HUD will flash and the PASS LED light on theconsole will change to rapidly flashing red. In pre-alarm, motion to the control console or pushing theside buttons on the console will return the PASS tothe sensing mode.If no motion is sensed for a full 35 seconds (includingthe pre-alarm warning), the PASS will go into fullalarm and can only be reset by pushing in on the twoside ON/OFF buttons on the console.9.1.3.2 PASS Safety Certification and Approval• The Viking Z SEVEN with PASS is CertifiedIntrinsically Safe for use in Class 1, Division 1,Group C and D; Class II, Div 1, Groups E,F, and G.• NFPA Specification: Meets the current NFPA 1981,2007 edition specifications and NPFA 1982, 2007edition.• NIOSH Specification: Meets the standards of42CFR, Part 849.1.3.3 PASS SpecificationsAlarm level: greater than 95 dbA @ 3 m (approxi-mately 10 ft)Visual / Audio Indicators:Turn ON Chirp from Console speaker, then chirp fromPASS alarm, and flashing green PASS light.Turn OFF Low beep from console speakerPre-alarm (No motion sensed for 25 seconds):PASS light turns from green to red and flashrate increasesEnd lights on mask display flash alternatelyPre-alarm warning with increasing soundlevelAlarm (No motion sensed for 35 seconds):PASS alarm soundsPASS LED light on console flashes redMask display shows cylinder pressureMaintenance After each use, clean the control console witha damp cloth and warm water.
