When used below freezing, care must be exercised to prevent moisture from entering the demand exhalation valve. The facemask should remain on the docking hook when not in use. On the AirSwitch model, the slide should be stored in the up position when not in use. For the RDV demand valve, the RDV should be stored on the docking station found on the waistbelt. This includes when cylinders are being changed. DURATION OF USE: Although the VIKING has been approved as either a 30-minute, 45-minute, or 60-minute breathing apparatus, the wearer’s varying work rate, physical condition and other factors could substantially shorten the actual usable duration of the unit. SCBA LIMITATIONS: An SCBA can only protect the wearer’s respiratory system. Other protection may be necessary to avoid contamination through skin absorption. If these types of materials are suspected, an effective full-body covering of impermeable material must be worn with the SCBA. A universal Level A HazMat suit is available for the VIKING SCBA from HazMat suit manufacturers. FACIAL HAIR: Facial hair or any other items which may interfere 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, head coverings, or anything else that may interfere with the correct seal of the facemask and/or nosecup to the face. See NFPA 1500 and ANSI Z88.2 EYE WEAR: Eye glasses shall not be used when the temple COPYRIGHT 2007 AVON - ISI bars interfere with the proper seal of the facemask to the face. If a user must wear corrective lenses while wearing the SCBA, they can be mounted in the facemask using a special lens mounting kit (AVON-ISI p/n 136003) available from AVON-ISI or through your local AVON-ISI authorized distributor. MANUAL BYPASS: In compliance with NIOSH requirements, the Viking SCBA has a manually operated bypass which provides a continuous flow of air to the facemask when required, independent of normal operation of the regulator. The bypass is opened by turning the red knob on the AirSwitch 90 degrees in the direction shown by the knob arrow. The RDV bypass opens by turning towards the user. Use of the bypass will shorten the duration of the SCBA. exposure, but can result in delayed impairment, illness or death.

The Viking Z SEVEN features a heads-up display (HUD) that monitors cylinder pressure and an emergency RIC connector that is used to refill the air of a down fire fighter. The Viking Z SEVEN model has VAS (Voice Amplification System) and data logging as standard features. Additional options of the Z SEVEN model include radio interface, voice activated communications, integrated PASS, buddy breather and airline. All Vikings are available with light weight carbon cylinders in 30, 45 or 60 minute rated durations. The AVON-ISI Viking Z SEVEN is a self-contained, open-circuit, compressed-air breathing apparatus, which is approved by the National Institute of Occupational Safety and Health (NIOSH) and certified compliant to NFPA 1981Standard on Open-Circuit Self-Contained Breathing Apparatus for Fire and Emergency Service, 2007 Edition. Positive pressure inside the facemask, both during inhalation and exhalation, ensures that any leakage due to improper fit or component failure will be an outward flow of air. The Viking Z SEVEN SCBA consists of several major components described in the following paragraphs. 1.1 yellow (low battery) green yellow red alarm. The HUD can also provide additional status indicators depending upon the options ordered. 1.2 AIRSWITCH® REGULATOR The patented AirSwitch second stage regulator is incorporated into the facemask and combines the demand and exhalation valves to greatly reduce breathing resistance. This also allows for a longer duration of cylinder use. A speech diaphragm provides excellent clarity and voice reproduction while incorporating the exhalation valve. FACEMASK The AVON-ISI full facemask assembly has a two point pullforward Nomex net harness with an optically-corrected, double curve high-impact polycarbonate visor. The visor’s scratch-resistant coating conforms to NFPA standards. The interior of the visor has a permanent anti-fog coating. The facemask standard seal is high-strength butyl blend and has a patented blended shape which fits the firefighter's helmet without readjustment. A standard black inner-mask nosecup reduces dead-air space and CO2 buildup. The facemask has CBRN labels affixed at both lower corners of the visor. Up for ambient air Down for supplied air The AirSwitch features a fresh air mode which allows users to go from cylinder air to outside air by depressing the two control slide tabs inward and then raising the slide upwards fully. Push down for cylinder or supplied air. The AirSwitch should stay open prior to donning and doffing of the VIKING SCBA. The AirSwitch is made of high performance engineered plastics and incorporates a true manual bypass control for emergency use. An in-mask HUD is mounted to the inner-mask nosecup. The mask display includes five LEDs: red = ¼ full, yellow = ½ full, 1st green = ¾ full, 2nd green = full, and the last elevated yellow = low battery indicator. The HUD indicates remaining cylinder pressure and provides the primary end-of-service time COPYRIGHT 2007 AVON - ISI 1.3 The Viking RDV regulator is a mask mounted second stage regulator with a 1/8th turn positive locking mechanism, which secures into the facemask. The RDV facemask incorporates a speech diaphragm that provides excellent red end of service speech clarity even alarm under heavy breathing. The standard HUD is still inside the facemask with the microphone. Docking the RDV on the facemask also aligns the electronic connection in one simple step. After removing the RDV from the facemask, it should be stored in the docking station on the waistbelt strap to keep free of dirt and debris. 1.4 1.6 BACKFRAME AND HARNESS The backframe and harness assembly utilize ergonomic design principles to produce a comfortable, low profile unit that evenly distributes the SCBA weight between the wearer’s hips and shoulders. The unique double-wall backframe of the Viking protects major airlines, the first stage reducer, bell alarm and digital components. A quick-release cylinder band fits a wide range of cylinders with an infinitely adjustable latch to ensure a tight fitting cylinder. FIRST STAGE PRESSURE REDUCER Air leaves the cylinder, passes through a sintered bronze filter in the handwheel elbow assembly, and then continues on through a high pressure flexible hose to the firststage pressure reducer where it is reduced to approximately 125 psi. The reducer is a simple piston type that requires no adjustment and incorporates an automatic, self-seating pressure relief valve to protect the low-pressure components downstream. It is made of high quality aluminum, and is securely mounted inside the backframe assembly. 1.5 The secondary End-of-Service indicator is a bell mounted inside the backframe which is set to activate at 23-27% of rated cylinder pressure per NIOSH and NFPA requirements. REMOVABLE DEMAND VALVE (RDV) REGULATOR END-OF-SERVICE INDICATORS The primary End-of-Service indicator is incorporated into the HUD. The display will flash a single red LED at 23% to 27% of rated cylinder pressure per NIOSH requirements. The primary end-of-service alarm meets NFPA 1981, 2007 Edition requirements. The harness material is NFPA compliant, custom woven KEVLAR®. The upper harness has very resilient foam rubber padding for added comfort and PBI/KEVLAR cover for maximum durability and protection. There is an optional backframe plate that can be ordered (p/n 099038) to reinforce the upper harness straps for departments that do heavy simulation training of fire fighter rescue operations. A lower lumbar pad is standard for added comfort and support. 1.7 CONTROL CONSOLE The control console and PASS assembly communicate with each other through a wireless network. The network uses a discreet frequency that eliminates noise and resistance to other radio frequencies. This wireless network joins the Control Console and PASS assembly together, allowing for constant data to be exchanged. The PASS motion sensor on the Z SEVEN is in the Control Console. When motion is detected, the PASS will reset for 25 seconds. NOTE: Only Duracell MN 1500 or Energizer E91 1.5 volt AA batteries are to be used with the battery packs. Be sure to place batteries in the direction as indicated on the battery compartment in order to prolong battery and fuse life. Use of other batteries will void the intrinsic safety approval. COPYRIGHT 2007 AVON - ISI 1.7.1 SERVICING CYLINDER VALVE After each use, and prior to recharging, the cylinder valve must be inspected for damage. If a new valve is replacing a valve that was damaged in use, it will be necessary to hydrotest the cylinder before installing the new valve. NOTE: Any maintenance on the valve that requires disassembly should be conducted by an AVON-ISI Authorized personnel or an AVON-ISI technician who is well trained in the hazards of high pressure equipment. Never attempt to remove the valve from the cylinder while there is any pressure in the cylinder. Open the valve completely to be sure it is empty. If the gauge shows pressure but you think the cylinder is empty, contact the AVON-ISI factory for advice by calling 888-474-7233. NOTE: Prior to revalving a cylinder, you must perform the following inspection: • Remove o-ring from sealing threads on cylinder valve. • Clean threads to remove any lubricant. • Inspect the cylinder threads, ensuring the threads are not distorted or cracked. • Inspect the valve threads, ensuring the threads are not distorted or cracked. • Install new o-ring. If any threads are distorted or cracked, the parts should be tagged “Out of Service” and be condemned. 1.8 CYLINDER AND VALVE ASSEMBLY A range of cylinder types and capacities are available on the VIKING 2216 psi and 4500 psi models. (Please see the table in Section 1.10 for specifics.) The cylinder valve is of aluminum construction with a permanent teflon coating. The valve outlet is a standard CGA-346 fitting on 2216 psi cylinders, and a standard CGA347 fitting on 4500 psi cylinders. Each valve has a dualreading pressure gauge. Valve protection is provided by an elastomeric bumper. See section 2.3.2 for inspection prior to use. all Viking ST models will have black handwheels no matter what the pressure rating of the cylinder.) The cylinder valve has two sets of male threads - one will screw into the cylinder and the other is used to attach to the pneumatics of the SCBA. The latter threads are referred to as CGA (Compressed Gas Association) threads. It is important to protect the CGA threads so that the pneumatics will always screw onto them without doing damage to the handwheel on the pneumatics. If any threads are distorted or cracked, the parts should be tagged “Out of Service” and be condemned. HANDLING PRECAUTIONS: NEVER LIFT OR CARRY UNIT BY THE HIGH PRESSURE HOSES. IF A HIGH PRESSURE HOSE BECOMES KINKED OR OTHERWISE DAMAGED, IT SHOULD BE REPLACED. CHECK FOR DAMAGE NEXT TO THE METAL ENDS OF THE HOSE. 1.9 RAPID INTERVENTION CREW (RIC) FITTING Every Viking Z SEVEN has a RIC fitting attached near the handwheel that allows a downed fire fighter to have their cylinder charged from an outside source. NFPA 1981, 2007 Edition requires this fitting on all SCBA’s manufactured for fire fighters. The RIC fitting is compatible with other manufacturers and is intended as an emergency refill only. The RIC fitting will not work as a transfill system between two SCBA’s. There is a dust cap cover for the fitting to prevent debris on the fitting. See section 4.7 for detailed working instructions. 1.10 Mounting SCBA If you mount the Viking Z Seven in a jump seat or mounting system of any vehicle, you must ensure that the mounting device meets NFPA standards and that the mounting device does not interfere with components such as cylinder, that could cause damage or cause sudden loss of cylinder pressure. The valve can be used with AVON- ISI cylinder assemblies between 23 cubic feet and 87 cubic feel. The cylinder valve has a burst disc type safety device to protect the cylinder from over pressurization. The cylinders and valve are matched according to pressure. The maximum pressure on the gauge built into the cylinder valve should match the pressure rating on the cylinder. A 2216 psi valve will not fit into a 4500 psi cylinder and vice versa. For easy recognition AVON- ISI has made 4500 psi handwheels red and a 2216 psi handwheel black.

Redness of skin 4.7 NOTE: If any time during charging, a leak is detected; discontinue charging and exit IDLH atmosphere immediately. NOTE: In a non-emergency situation, cylinders shall not be refilled through the RIC. RIC FITTING PROCEDURES bottom of RIC charging hose The RIC fitting is designed as an emergency refill only and has specific uses and functions per NFPA 1981, 2007 Edition. The system can only be used to fill approved SCBA cylinders. The RIC fitting has an internal balanced piston that prevents over pressurization of a cylinder. A check valve prevents fire fighters from transfilling SCBA’s, or any other unapproved use on AVON-ISI products. Users will be able to have a 4500 psi cylinder as a supplied air system and connect to a 2216 psi SCBA RIC connector. Air will stop flowing automatically from the high-pressure cylinder when the correct pressure (2216 or 4500) is achieved. To recharge a cylinder on a downed fire fighter, an approved charging hose must be used. The AVON-ISI Rescuer uses the following approved hoses: a 3 foot RIC Charging Hose (p/n 162051), a 6 foot RIC Charging Hose (p/n 162052), or a 10 foot RIC Charging Hose (p/n 162053) for filling the cylinder in IDLH atmospheres. 4.7.1 Open cylinder valve of supplied air and remove the dust cap from the RIC charging hose. Inspect the fire fighters cylinder for damage and ensure that the cylinder valve is fully opened. 4.7.3 Once clear of an IDLH atmosphere, close the cylinder valve on the RIC charging hose. Ensure there is no debris in the dust cap prior to pushing on the dust cap. The bottom of the dust cap reads "press to relieve". With dust cap in place, push down on dust cap on a hard surface to bleed pressure. 4.7.4 Top off cylinder attached to charging hose before next use to ensure proper service time. IMPORTANT DO NOT REMOVE ANY EQUIPMENT UNTIL YOU ARE CLEAR OF AN IDLH ATMOSPHERE. 4.8 PASS The wireless network between the PASS and control console must always be updating. You must verify on start-up that the console's LEDs are green. If console LED flashes red for more than 30 seconds, the PASS will go into alarm and will not turn off until backframe batteries are removed. Usually the cause is low battery from either power source that never was changed. WARNING CYLINDERS THAT ARE DAMAGED MAY SUDDENLY RUPTURE IF CHARGED. 4.7.2 Remove dust cap from the RIC fitting on the SCBA and attach the RIC charging hose to it. Listen for leaks on the SCBA that is being filled. Recharging will take between 2-4 minutes, depending on the cylinder duration and pressure. When the pressures equalize, unplug the charging hose from the SCBA and replace dust covers and exit. During a prolonged rescue, users can leave the supplied air cylinder plugged into the downed fire fighter’s SCBA, adding additional duration to the cylinder.

(Note: pressure drops when cylinder temperature drops.) 8.3 BATTERY PACKS BATTERIES FOR CONTROL CONSOLE: The control console battery pack powers the HUD, VAS and radio interface. The battery pack accommodates six alkaline batteries. The low battery indicator is the in-mask HUD offset top yellow light, displaying a solid yellow light. The LED light on the console will be a solid red. BATTERIES FOR PASS: The PASS battery pack within the backframe powers only the PASS option. It accommodates two sets of four AA alkaline batteries. Each set of four is independent of the other in case of a battery failure. As battery voltage drops, each set of four batteries switch to the highest voltage side available until the HUD low battery indicator shows that all eight batteries need replacing. The low battery indicator is the in-mask HUD offset top yellow light, displaying a solid yellow light. The PASS alarm will also emit an audible chirp COPYRIGHT 2007 AVON - ISI every 12 seconds and the console LED pass light will be red. 8.3.5 PASS BATTERY REPLACEMENT: With the battery pack removed from the backframe, remove old batteries from battery pack and replace with new AA alkaline batteries. Ensure that each battery is properly installed, noting polarity as shown in battery compartment and battery compartment tray. Ensure that each battery touches both battery pack contacts. Ensure battery pack seal is in place, free from debris. Prior to placing the battery pack within the backframe, ensure that the “T” guard between the battery posts is in place, protecting against shorting out the battery fuse. Push battery pack into battery compartment such that the clips snap over the two brass contact pins. The control console will turn on, emit an audible chirp, and then turn off. Secure battery pack to backframe with four Torx screws. 8.4 NET HEAD HARNESS REPLACEMENT NOTE: Electronics will operate at least two hours in low battery mode. Battery life depends on many variables. Some fire departments may use the Viking once every day for six months before they have to change batteries. Another fire department may only use the Viking once a month. Both batteries may have to be replaced within six months. The difference is the amount of power loss from using the electronic options. The Viking Z SEVEN has several options that can increase battery consumption. The VAS draws about 700 ma. and radio communications draws about 250 ma. The rest of the lights that use LED’s draw very little power. Heat and cold also affect battery life. During internal heat tests (160 ºF) and cold tests (-25º F) battery life dropped by 50%. WARNING WHEN REPLACING THE AA BATTERIES, ENSURE THAT THE BATTERIES ARE NOT INSTALLED BACKWARDS WITHIN THE BATTERY PACK. REVERSING THE POLARITY OF THE BATTERY FOR EVEN ONE SECOND CAN CAUSE THE BATTERY TO LEAK OVER TIME. IF A BATTERY IS INSTALLED BACKWARDS, DO NOT USE THIS BATTERY BUT DISPOSE OF THIS BATTERY.

COPYRIGHT 2007 AVON - ISI Level 9.1.2 COMMUNICATIONS The Viking Z SEVEN electronics and pneumatics turn on automatically when the cylinder valve is opened. The SCBA electronics can be turned on manually by depressing the lower two ON/OFF buttons on the console. 9.1.2.1 VOICE AMPLIFICATION SYSTEM (VAS) The VAS uses a sealed, in-mask microphone to capture the user's voice, amplifies it, and then broadcasts it from the speaker on the console. This is particularly useful in communicating with other people nearby when the SCBA is in the positive pressure mode. VAS is preset to be voice activated. You must speak slightly louder than normal to activate VAS. 9.1.2.3 The VAS is on standby mode whenever the SCBA cylinder is opened. When speech is sensed, it turns on the amplifier and sends it to the console. Shortly after speech ends, the amplifier goes back into standby mode. VAS can be turned off if the user desires. To turn off the VAS, the cylinder valve must be opened and power activated to the control console. To disable the VAS, push inward on the Function key and push the PTT button. An audible chirp should be heard. VAS is now in the off setting. To turn VAS back on, repeat the above function. When the Viking SCBA is powered down, the system will defaut to VAS "on" when the electronics are activiated. 9.1.2.2 VOICE ACTIVATION LEVELS The microphone activation level is adjustable for individual preference. Push the Shift button on the front of the console inward and hold. The HUD facemask display will flash the preset point of the voice activation level. To change the settings, while holding the Shift key, push the PTT button once. This will raise the activation point. Continue to push the PTT to your personal preference. Release the Shift key to set activation level. To go from Level 4 to Level 1, hold the Shift key inward and push the PTT button again. There are ten set points for the voice activation level. Level 1 is the most sensitive activation point up to a Level 10 being the least sensitive activation point. Each level will be displayed a specific number of HUD light(s) that activate. With each increased level, less inhalation breathing noise is heard, but voice must be raised higher to begin amplification in order for the microphone to detect speach. The settings are a follows: Flashing Red Red, Flashing Yellow Red, Yellow, Flashing Green Red, Yellow, Green, Flashing Green Red, Yellow, Green, Green Flashing Red, Low bat Red, Flashing Yellow, Low Bat Red, Yellow, Flashing Green, Low Bat Red, Yellow, Green, Flashing Green, Low Bat Red, Yellow, Green, Green, Low Bat Amount breathing noise amplified The Viking Z SEVEN is available with several communication options. The microphone is a standard feature and is mounted inside the facemask on the nosecup. It offers excellent speech clarity. All communications have a noise suppressor to reduce exhaled breathing air noise. Note: HUD LED Pattern 10 10 RADIO INTERFACE When the Z SEVEN is equipped with radio interface, it has the ability to significantly decrease the background noise of outgoing transmissions. This is due to the placement of the sealed microphone inside the nosecup, which is well insulated from ambient noise. Incoming transmissions are broadcast from the console speaker. On units designed for use by law enforcement, incoming transmissions are recieved through an optional ear speaker. A separate radio lead is required to integrate the console to the radio. The radio connects to the interface cable on the lower control console. There are two ways to key the radio and transmit: in the manual mode, press and hold the Push-To-Talk button (PTT) on the side of the console. As an indication that the PTT button has been pressed, the right LED indicator light turns green on in the console display and a solid green light on the HUD. If VAS is installed with Radio Interface, the VAS is disabled whenever the radio is keyed. To activate the hands free VOX mode, press and release the PTT button twice within one second (double click). A flashing red light will illuminate on the control console display. In this mode, the radio is keyed automatically whenever the SCBA senses user speech. The HUD will illuminate only the top green (full) light whenever user speech has keyed the radio. When speech has ended, the unit automatically turns off the amplifier to conserve the battery and the HUD again monitors cylinder pressure. To end the hands free mode, double click the PTT button again. 9.1.3 COPYRIGHT 2007 AVON - ISI Viking Z SEVEN PASS The PASS on the Viking Z Seven is an NFPA 1982 compliant Personal Alert Safety System (PASS) that is integrated with the SCBA and with the other 19 electronic systems. It requires no adjustments. Pre-alarm The PASS is automatically activated when the cylinder is opened or may be manually turned on by pushing both "ON/OFF" side buttons on the console simultaneously. Once turned on, it normally operates in the “sensing” mode where it looks for motion at the console. Alarm 9.1.3.1 PASS Operating Instructions WARNING ALWAYS TEST THE PASS PRIOR TO ENTRY INTO A HAZARDOUS ATMOSPHERE. IF THE LOW BATTERY WARNING SIGNAL ACTIVATES, INSTALL NEW BATTERIES AFTER USE OR PRIOR TO USING THE VIKING Z SEVEN. THE CONTROL CONSOLE WITH PASS SHOULD BE POSITIONED FLAT AGAINST THE SHOULDER STRAP. When the PASS is turned on, a chirp will be heard on the control console speaker, followed by a chirp from the PASS alarm on the backpack. Additionally, the left LED users prospective on the console display will slowly flash green when PASS is on. When there is a lack of motion sensed at the control console for over 25 seconds, the PASS will go into pre-alarm and sound an audible warning that will progressively get louder until the PASS goes into full alarm. While in pre-alarm, the red (¼ full) and top green (full) lights on the HUD will flash and the PASS LED light on the console will change to rapidly flashing red. In prealarm, motion to the control console or pushing the side buttons on the console will return the PASS to the sensing mode. If no motion is sensed for a full 35 seconds (including the pre-alarm warning), the PASS will go into full alarm and can only be reset by pushing in on the two side ON/OFF buttons on the console. 9.1.3.2 PASS Safety Certification and Approval • The Viking Z SEVEN with PASS is Certified Intrinsically Safe for use in Class 1, Division 1, Group C and D; Class II, Div 1, Groups E,F, and G. PASS light turns from green to red and flash rate increases End lights on mask display flash alternately Pre-alarm warning with increasing sound level (No motion sensed for 35 seconds): PASS alarm sounds PASS LED light on console flashes red Mask display shows cylinder pressure Maintenance After each use, clean the control console with a damp cloth and warm water. Do not use cleaning solvents. Inspect each unit for signs of physical damage. Life Depending on the frequency of use, the PASS may have to be retired from service if severely damaged. 9.1.3.4 PASS Limitations The VIKING Z SEVEN is designed to meet the design and performance requirements for Personal Alert Safety Systems (PASS) to be used by firefighters engaged in rescue, fire fighting, and other hazardous duties defined in the NFPA 1982 Standard on PASS, 2007 edition. Failure to ensure that the Viking Z SEVEN PASS is fully operational prior to use may expose the user to serious injury or death. Although the Viking Z SEVEN PASS meets the current standards, there is no guarantee against PASS failure. Most performance properties of the PASS cannot be tested by users in the field. 9.1.3.5 PASS Warranty AVON-ISI warrants the Viking Z SEVEN PASS to be free from defects in workmanship and materials for a period of one year from date of purchase. AVON-ISI will not repair or replace any merchandise that has been damaged from accident, misuse, or abuse while in the possession of the end-user.
