APPROVALS
All Viking Z SEVEN SCBA are CBRN certified and NIOSH ap-
proved, meeting the NFPA 1981 Standard, 2007 Edition and
the NFPA 1982 Standard, 2007 Edition (when equipped with
PASS) requirements.
NIOSH/OSHA WARNINGS
The following warnings are given in accordance with accept-
ed 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 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 drum
WORKING TEMPERATURES: The VIKING SCBA is ap-
proved 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 de-
mand 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 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 actual
usable duration of the unit.
SCBA LIMITATIONS: An SCBA can only protect the wear-
er’s respiratory system. Other protection may be neces-
sary 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 avail-
able for the VIKING SCBA from HazMat suit manufactur-
ers.
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, head
coverings, or anything else that may interfere with the correct
seal of the facemask and/or nosecup to the face.
COPYRIGHT 2007 AVON - ISI

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 distribu-
tor.
MANUAL BYPASS: In compliance with NIOSH requirements,
the Viking SCBA has a manually operated bypass which pro-
vides 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 de-
grees in the direction shown by the knob arrow. The RDV by-
pass opens by turning towards the user. Use of the bypass
will shorten the duration of the SCBA.

COPYRIGHT 2007 AVON - ISI 3
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) as a standard feature. Additional options of the Z
SEVEN model include radio interface, voice activated
communications, integrated PASS with data logging, 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-cir-
cuit, 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 compo-
nents described in the following paragraphs.
1.1 FACEMASK
The AVON-ISI full facemask as-
sembly has a two point pull-for-
ward Nomex net harness with an
optically-corrected, double curve
high-impact polycarbonate visor.
The visor’s scratch-resistant coat-
ing conforms to NFPA standards.
The interior of the visor has a per-
manent 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 la-
bels affixed at both lower corners of the visor.
1.0 DESCRIPTION OF VIKING Z SEVEN SCBA
An in-mask HUD is mount-
ed to the inner-mask nose-
cup. The mask display in-
cludes five LEDs: red = ¼
full, yellow = ½ full, 1st
green = ¾ full, 2nd green =
full, and the last elevated
yellow = low battery indica-
tor. The HUD indicates re-
maining cylinder pressure
and provides the primary
end-of-service time alarm.
The HUD can also provide
additional status indicators
depending upon the op-
tions ordered.
1.2 AIRSWITCH
®
REGULATOR
The 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 also
allows for a longer duration of cylinder use. A speech dia-
phragm provides excellent clarity and voice reproduction
while incorporating the exhalation valve.
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 engi-
neered plastics and incorporates a true manual bypass con-
trol for emergency use.
S- SPECIAL OR CRITICAL USER’S INSTRUCTIONS,
CONTINUED
This approval applies only when the device is supplied with
respirable breathing air through 6 to 300 feet of hose at air
pressures between 80 to 120 pounds per square inch gauge or
from self contained air supply.
Note: Viking CBRN SCBAs are not approved for supplied air use
in confirmed or potential CBRN environments.
If the supplied air fails, open the cylinder valve, unplug supply air
and proceed to fresh air immediately.
• Use adequate skin protection when worn in gases and vapors
that poison by absorption (example: hydrocyanic-acid gas).

1.3 REMOVABLE DEMAND VALVE (RDV) REGULATOR
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 speech clarity even
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 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 first-stage pressure
reducer where it is reduced to ap-
proximately 125 psi. The reducer
is a simple piston type that re-
quires no adjustment and incorpo-
rates an automatic, self-seating
pressure relief valve to protect the
low-pressure components down-
stream. It is made of high quality
aluminum, and is securely mount-
ed inside the backframe assem-
bly.
1.5 END-OF-SERVICE
INDICATORS
The primary End-of-Service indi-
cator 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 secondary End-of-
Service indicator is a bell
mounted inside the back-
frame which is set to acti-
vate at 23-27% of rated
cylinder pressure per
NIOSH and NFPA re-
quirements.
1.6 BACKFRAME AND HARNESS
The backframe and harness assembly utilize ergonomic de-
sign 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-re-
lease cylinder band fits a
wide range of cylinders
with an infinitely adjust-
able latch to ensure a
tight fitting cylinder.
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 maxi-
mum durability and protection. There is an optional back-
frame plate that can be ordered (p/n 099038) to reinforce the
upper harness straps for departments that do heavy simula-
tion 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 fre-
quency that eliminates noise and
resistance to other radio frequen-
cies. This wireless network joins
the Control Console and PASS
assembly together, allowing for
constant data to be exchanged.
There are two motion sensors on
the Z SEVEN, one in the Control
Console and one in the PASS assembly inside the back-
frame. When one assembly detects motion, the PASS will re-
set 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 pro-
long battery and fuse life.

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 hy-
drotest 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 fol-
lowing 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.
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 perma-
nent teflon coating. The valve outlet is a standard CGA-346
fitting on 2216 psi cylinders, and a standard CGA-347 fitting
on 4500 psi cylinders. Each valve has a dual-reading pres-
sure gauge. Valve protection is provided by an elastomeric
bumper. See section 2.3.2 for inspection prior to use.
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:
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 PRES-
SURE HOSES. IF A HIGH PRESSURE HOSE BE-
COMES 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 cyl-
inder charged from an outside source. NFPA 1981, 2007 Edi-
tion requires this fitting on all SCBA’s manufactured for fire
fighters. The RIC fitting is compatible with other manufactur-
ers and is intended as an emergency refill only. The RIC fit-
ting 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.

TECHNICIAN MAINTENANCE
AT LEAST ONCE PER YEAR, THE ENTIRE SCBA
SHOULD BE PLACED OUT OF SERVICE AND
TAGGED FOR ANNUAL FLOW TESTING BY AN
AVON-ISI AUTHORIZED TRAINED TECHNICIAN.
2.4 SCBA RETIREMENT
Over the course of time, the Viking SCBA needs to be evalu-
ated on its' overall condition. Inspect the Viking's harness as-
sembly for frayed, deteriorating harness', stress cracks in the
backframe and in general, it's overall condition. Another con-
sideration is passing the annual dynamic flow testing require-
ments. Over time components may need to be replaced or
consideration must be made to retire the SCBA.
Fire Department that plans on retiring their SCBA's or no
longer meet the current NFPA requirements, should review
NFPA 1852, 2002 Edition, section 4.3 and 4.6 for guidelines
on retiring an SCBA.

3.1.8 To connect the facemask to the Viking unit, connect
electronics plug partially into socket, then connect
facemask plug into connector. Press firmly in to lock
both fittings into each socket. A click should be
heard when it is locked in place securely.
Note: When connecting the facemask hose to the
connector, make sure both hoses are connected and
the socket sleeve has moved forward. If socket
sleeve has moved forward without the facemask
hose connected, air will leak out of the socket
connector.
For the RDV mask, the HUD electronic connection
is made when the RDV is docked into the facemask.
Prior to donning the RDV, ensure that the contact
pins are free of any debris.
Note: In an IDLH atmosphere, such as a CBRN response,
ensure that the facemask is connected to the
pneumatic connection prior to entering the
hazardous area to prevent contamination.
Note: Prior to docking the RDV, the user can perform a
negative pressure check on the AVON-ISI mask.
Place your hand to block off the RDV opening in the
facemask. Inhale slightly and hold your breath.
Facemask should move inward slightly and stay in
that position unit user exhales. It may be difficult to
perform this with a gloved hand. Annual fit testing is
required to ensure proper fit.
Note: It is not necessary to perform a negative pressure
check on the AirSwitch because it is designed as a
positive pressure facemask. AVON-ISI recommends
annual fit testing to ensure a proper fitting facemask.

3.2 SAFETY CHECKS
WARNING
THESE SAFETY CHECKS MUST BE PERFORMED
BEFORE ENTERING A HAZARDOUS AREA. FAIL-
URE TO PERFORM THESE CHECKS MAY RESULT
IN RESPIRATORY INJURY OR DEATH.
3.2.1 AirSwitch positive pressure fit check: With cylin-
der valve open, push down on the control slide to activate air
supply and breathe normally.
RDV positive pressure fit check: With the mask
donned and the RDV docked, inhale to activate air-
flow.
Insert two fingers between the facemask and face. Gently lift
the facemask seal away from the face and ensure a good
outward flow of air, showing that the facemask pressure is
positive. Reseal facemask and stop breathing for 3 seconds.
There should be no sound of air leaking from the regulator,
and there should be no airflow sensed in the eye region of
the mask.
3.2.2 ALARM CHECK: Close the cylinder valve and con-
tinue to breathe normally. As the air reaches the ¼ full level
the red LED light should flash rapidly and all other lights
should be out. The secondary bell alarm should also activate.
3.2.3 Open cylinder valve. Take two to three deep breaths
to ensure you are getting adequate air into the facemask. The
facemask should not move towards your face.
3.2.4 AIRSWITCH BYPASS CHECK: The red bypass
knob is located in the center of the AirSwitch. Turn the by-
pass knob clockwise as viewed inside the mask (the direction
shown by the knob arrow) to open the bypass valve. A con-
stant flow of air should pass into the facemask. Turn the knob
in the opposite direction to turn the bypass valve off.
RDV BYPASS CHECK: The bypass knob on the
RDV is located on the right side (from the wearer
view). To open, rotate knob towards the user fully. A
constant flow of air should pass into the facemask.
Turn the knob in the opposite direction to close.
3.2.5 RECHECK CYLINDER PRESSURE: Check the
heads-up display. Four lights should be "on". The
top green light may be flashing, indicating at least 7/
8th full.
Verify the analog gauge is at or above the 7/8th level.

IMPORTANT
THE USER SHOULD BE TRAINED ON HOW TO HANDLE A
POSSIBLE EMERGENCY BEFORE ENTERING A HAZARD-
OUS AREA.
The Viking SCBA can be equipped with a variety of fully-inte-
grated solid state features that offer safety and communica-
tion advantages for the user. Review section 9 for detailed in-
structions of available options.
4.1 READING THE HEADS-UP DISPLAY (HUD)
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.
3.2.6 BATTERY CHECK: The top yellow LED will be "ON"
when the control console batteries are low. If the
pass batteries are low, displays red LED on console
and the pass alarm will chirp every 15 seconds. The
LED on the console will be red. If the SCBA shows a
low battery warning, replace batteries in accordance
with section 8.3.
3.2.7 VAS CHECK
3.2.7.1 Turn SCBA on by either opening cylinder valve or by
manually 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 and
ensure its intelligibility and function.

4.7 RIC FITTING PROCEDURES
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.

4.7.2 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 pres-
sures equalize, unplug the charging hose from the
SCBA and replace dust covers and exit. During a pro-
longed rescue, users can leave the supplied air cylin-
der plugged into the downed fire fighter’s SCBA, add-
ing additional duration to the cylinder.
Note: If any time during charging, a leak is detected; dis-
continue charging and exit IDLH atmosphere immedi-
ately.
Note: In a non-emergency situation, cylinders shall not be
refilled through the RIC.
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 re-
lieve". 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.

chirp every 12 seconds and the console LED pass
light will be red.
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 re-
placed within six months. The difference is the
amount of power loss from using the electronic op-
tions. 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 bat-
tery 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. RE-
VERSING THE POLARITY OF THE BATTERY FOR
EVEN ONE SECOND CAN CAUSE THE BATTERY
TO LEAK OVER TIME. IF A BATTERY IS IN-
STALLED BACKWARDS, DO NOT USE THIS BAT-
TERY BUT DISPOSE OF THIS BATTERY. FAILURE

9.1.2.3 RADIO INTERFACE
When the Z SEVEN is equipped with radio interface,
it has the ability to significantly decrease the back-
ground 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 re-
cieved through an optional ear speaker.
A separate radio lead is required to integrate the
console to the radio. The radio connects to the inter-
face 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 indi-
cation that the PTT button has been pressed, the
right LED indicator light turns green on in the con-
sole display and a solid green light on the HUD. If
VAS is installed with Radio Interface, the VAS is dis-
abled whenever the radio is keyed.
To activate the hands free VOX mode, press and re-
lease the PTT button twice within one second (dou-
ble 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 auto-
matically turns off the amplifier to conserve the bat-
tery and the HUD again monitors cylinder pressure.
To end the hands free mode, double click the PTT
button again.
.1.2 COMMUNICATIONS
The Viking Z SEVEN is available with several communication
ptions. The microphone is a standard feature and is mount-
d inside the facemask on the nosecup. It offers excellent
peech clarity. All communications have a noise suppressor
o reduce exhaled breathing air noise.
Note: 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 but-
tons on the console.
.1.2.1 VOICE AMPLIFICATION SYSTEM (VAS)
The VAS uses a sealed, in-mask microphone to cap-
ture the user's voice, amplifies it, and then broad-
casts it from the speaker on the console. This is par-
ticularly 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.
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 in-
dividual preference. Push the Shift button on the
front of the console inward and hold. The HUD face-
mask display will flash the preset point of the voice
activation level. To change the settings, while hold-
ing 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 four set points for the voice activation lev-
el. Level 1 is the most sensitive activation point up to
a Level 4 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:

9.1.3 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 elec-
tronic systems. It requires no adjustments.
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.
9.1.3.1 PASS Operating Instructions
WARNING
ALWAYS TEST THE PASS PRIOR TO ENTRY INTO
A HAZARDOUS ATMOSPHERE. IF THE LOW BAT-
TERY 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 or PASS device in backframe for over 25
seconds, the PASS will go into pre-alarm and sound an audi-
ble 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 pre-
alarm, motion to the control console or pushing the side but-
tons 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

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 de-
sign and performance requirements for Personal
Alert Safety Systems (PASS) to be used by firefight-
ers engaged in rescue, fire fighting, and other haz-
ardous duties defined in the NFPA 1982 Standard
on PASS, 2007 edition. Failure to ensure that the Vi-
king Z SEVEN PASS is fully operational prior to use
may expose the user to serious injury or death. Al-
though the Viking Z SEVEN PASS meets the current
standards, there is no guarantee against PASS fail-
ure. Most performance properties of the PASS can-
not 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. AVON-ISI
shall not be liable for any direct, incidental or other
consequential loss or damage arising out of the fail-
ure of the device to operate. PASS issues may be
reported to AVON-ISI Customer Service at (888)
474-7233. After working with the manufacturer to re-
solve any issues, they may be reported to SEI at
(703) 525-2354.
9.2 VIKING STEALTH MODE
The Viking Z-ST model designed for law enforcement has the
capability of turning off the control console. The Stealth Mode
is a standard feature of the Viking Z-ST.
On units with the stealth mode option, depress the funtion
key and the PPT button on the control console for one sec-
ond to turn off VAS. The HUD will still display cylinder pres-
sure and acknowledge radio transmissions. All communica-
tions will be received through the optional ear piece interface
cable. To reset to normal mode, depress the function key and
PTT button on the control console for one second.

Viking SCBA.
9.3.2.1 The EAS tether is designed so you do not have to
unplug the regulator hose from the facemask in an
IDLH atmosphere. The EAS tether includes two feet
of retractable hose stored within the backframe. The
end of the hose includes two couplings, one male
and one female, and a combination handle/dust cap.
When stored, the EAS handle is located on the lower
right side of the backframe (from the user’s perspec-
tive). In an emergency, the EAS tether is pulled out
of the backframe and connected to another EAS teth-
er forming a four foot long combined tether hose.
9.3.2.2 If the EAS is used, egress immediately to a safe, re-
spirable atmosphere. The rescuer must monitor their
cylinder air closely due to increased air consumption.
9.3.2.3 Although the EAS is a NIOSH accepted SCBA ac-
cessory, NIOSH does not approve the use of EAS
devices. Use of the EAS voids NIOSH approvals
while in use.
9.3.2.4 REMOVE THE EAS TETHER: Using your right
hand, reach back above the cylinder valve knob and
locate the buddy breather handle. Pull down on the
handle and completely pull out the hose. The tether
is approximately two feet long.
9.3.2.5 CONNECT TO ANOTHER EAS TETHER: Each
EAS tether includes both male and female quick
connect couplings. Connect one coupling, either
male or female, to the opposite coupling on the other
EAS tether. Air will start to flow immediately.
9.3.2.6 Egress to a safe, respirable atmosphere and then
disconnect EAS tethers.
9.3.2.7 To store EAS tether, while the SCBA pneumatics are
pressurized, push the hose length back into the
backframe. Snap the handle into the backframe and
replace dust caps.
