NIOSH/OSHA WARNINGS
The following warnings are given in accordance with accepted safety conventions and/or NIOSH/OSHA requirements,
and apply to the use of breathing apparatus in general.
HEALTH LIMITATIONS: Wearers of the SCBA should be
certified medically fit prior to use. In addition, there are both
physiological and psychological limitations which should be
considered before using SCBA. They include, but are not limited 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 drum
WORKING TEMPERATURES: The VIKING SCBA is approved for respiratory protection during entry into or escape
from oxygen deficient atmospheres, gases, and vapors at
temperatures above -25°F. 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

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.
T-
Direct contact with CBRN agents requires proper handling of the
SCBA after each use and between multiple entries during the
same use. Decontamination and disposal procedures must be
followed. If contaminated with liquid chemical warfare agents,
dispose of the SCBA after decontamination.
U - The respirator should not be used beyond 6 hours after initial
exposure to chemical warfare agents to avoid possibility of agent
permeation.

1.0 DESCRIPTION OF VIKING Z SEVEN SCBA
All Viking Z SEVEN SCBA are NIOSH CBRN agent approved,
NIOSH approved and NFPA 1981Standard, 2007 Edition
compliant. 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

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.

1.6
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.

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. (Exception:

4.1.1
The HUD includes five LED lights: two green, two
yellow and one red. Each of the 4 LEDs in a row
represents a quarter increment of the rated service
pressure. As cylinder pressure decreases, the LEDs
change status. At full rated service pressure, all four
LEDs are on. As cylinder pressure drops below full,
the top green LED begins blinking. At ¾ rated service
pressure, the top green LED turns off and the next
green LED begins blinking. At ½ rated service
pressure, the second green LED turns off and the
yellow LED begins blinking. At ¼ rated service
pressure, the yellow LED turns off, and the red LED
blinks at a fast rate. The top offset yellow light is a low
battery indicator. Refer to the following table for more
information regarding mask pressure display interpretation.

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.

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%.

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

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

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.

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

Viking SCBA.
9.3.1.1 The Airline Attachment is located on the left waistbelt
strap. It is approved with Hansen HK. Hansen HK
couplings include locking devices.
IMPORTANT
Only Hansen HK airline fittings are offered on CBRN certified
units.
The use of airline attachments on CBRN approved units are
not NIOSH CBRN approved for use in confirmed or potential
CBRN environments.
9.3.1.2 When using supplied air, the user must ensure that
the cylinder valve is closed. Failure to do so may
result in reduced cylinder duration.
9.3.1.3 Airline respirators can be used only when the
respirators are supplied with respirable air meeting
the requirements of CGA G-7.1 Grade D or higher
quality.
9.3.1.4 When used as a combination apparatus, only 20% of
the service pressure may be used on entry.
