DESCRIPTION
DESCRIPTION
FireHawk M7 Air Masks from MSA are pressure-demand,
self-contained breathing apparatus (SCBA) certified by the
National Institute for Occupational Safety and Health
(NIOSH) for use in atmospheres immediately dangerous to
life or health:
``Immediately dangerous to life or health’’ means condi-
tions that pose an immediate threat to life or health or
conditions that pose an immediate threat of severe expo-
sure to contaminants, such as radioactive materials,
which are likely to have adverse cumulative or delayed
effects on health [Title 42 CFR, Part 84.2, (Q)].
This Air Mask complies with the National Fire Protection
Association (NFPA) Standard 1981 for Open-Circuit Self-
Contained Breathing Apparatus for Fire Fighters
This Air Mask has been designated by NIOSH as being
CBRN (chemical, biological, radiological, and nuclear)
Agent Approved. It complies with the special tests under
NIOSH 42 CFR 84.63(c); Chemical Agent Permeation and
Penetration Resistance Against Distilled Sulfur Mustard
(HD) and Sarin (GB) and the Laboratory Respirator
Protection Level (LRPL) tests.

FIREHAWK M7 AIR MASK COMPONENTS
PR14 FIRST STAGE REGULATOR
The PR14 First Stage Regulator reduces the pressure
from the cylinder and valve assembly to an intermediate
pressure, which is in turn further reduced by the Firehawk
Second Stage Regulator to a pressure that is respirable
by the user.
The PR14 First Stage Regulator incorporates a down-
stream design and dual springs.
The regulator incorporates a large, easily replaceable, sin-
tered filter to capture particulates that may be in the air
stream.
FIREHAWK SECOND STAGE REGULATOR
The Firehawk Regulator is a pressure-demand regulator,
which maintains a positive pressure in the facepiece while
the air mask is in use.
The Firehawk Regulator attaches to the facepiece via a
slide-to-connect or a push-to-connect feature.
The Firehawk Regulator has two available covers, purge
and hard cover. The purge cover offers the user the ability
to manually activate the regulator or to provide a quick
burst of air during use without using the bypass knob.
There are also two types of Firehawk Regulator intermedi-
ate pressure hose connections, threaded and quick-con-
nect.
CYLINDER AND VALVE ASSEMBLY
*as approved by NIOSH
The cylinder valve includes a metal valve body, threaded
connection for filling and attachment of the Audi-Larm
Alarm, handwheel, safety disc (burst disc), and pressure
gauge.
The pressure gauge continuously shows the air pressure
in the cylinder.
The handwheel is used to open and close the cylinder
valve.

AUDI-LARM ALARM WITH URC ASSEMBLY
The Audi-Larm Alarm rings when there is approximately
25% of the air mask’s rated service time remaining and
when the cylinder valve is first opened, providing an audi-
ble indication that the alarm is working properly.
A high pressure hose delivers air at cylinder pressure from
the Audi-Larm Alarm to the PR14 First Stage Regulator.
Note: The remaining service time calculations are based
on a 40 LPM (liters per minute) NIOSH breathing rate.
All FireHawk M7 Air Masks are equipped with an Audi-
Larm Alarm that includes a URC Assembly (Universal
Rescue Connection). The URC Assembly is a male quick-
fill inlet for use by Rapid Intervention Crews for emer-
gency filling of the SCBA or during transfill operations.
Also included with the URC Assembly is a pressure relief
valve for protection of the cylinder burst disc.
FIREHAWK M7 CARRIER AND HARNESS ASSEMBLY
DO NOT use this carrier and harness assembly as a
vertical raising or lowering device. Failure to follow
this warning can result in serious personal injury or
death.
The carrier consists of a backplate, a cylinder band with
latch to hold the cylinder, and a harness, consisting of
shoulder pads, chest strap (optional), adjustable pull straps,
waist belt, waist belt mounted regulator retainer, swiveling
lumbar pad (optional), and Rescue Belt (optional).
ULTRA ELITE FACEPIECE
The facepiece is available in three sizes (Small, Medium,
and Large).
The facepiece lens is super-hardcoated to meet the
requirements of NFPA 1981.
The facepiece has a low-resistance, pressure-demand
exhalation valve.
An inhalation check valve in the inlet housing keeps mois-
ture and contaminants out of the Firehawk Regulator.
The facepiece has a speaking diaphragm for clear com-
munication.
FIREHAWK M7 HUD
The FireHawk M7 HUD, located on the Ultra Elite
Facepiece allows a user to see cylinder pressure in one
quarter cylinder increments, PASS pre-alarms, battery sta-
tus, and telemetry information (optional) while wearing the
air mask.
FIREHAWK M7 CONTROL MODULE (PASS DEVICE)
The FireHawk M7 Control Module is the user’s interface
with the air mask.
The FireHawk M7 Control Module is equipped with an
analog gauge as well as an LCD to provide the user vital
information: numeric and iconic cylinder pressure, battery
status, thermal alarm (optional), and time remaining.
If the air mask is equipped with the optional FireHawk M7
Telemetry Module, the radio link status and evacuation
alarms are displayed.
The integrated PASS motion sensor is housed within the
FireHawk M7 Control Module.
FIREHAWK M7 POWER MODULE (PASS DEVICE)
The FireHawk M7 Power Module on the lower portion of
the backplate houses the batteries, serves as the cylinder
stop, emits audible PASS alarms, and has buddy lights.
The FireHawk M7 Power Module is linked to the FireHawk

DESCRIPTION
FIREHAWK M7 TELEMETRY MODULE
The FireHawk M7 Telemetry Module provides the firefight-
er with two-way communication with Incident Command.
The firefighter’s vital statistics such as cylinder pressure,
service time remaining, PASS alarm, low battery alarm,
and thermal alarm are transmitted back to Incident
Command. Also, the firefighter has the ability to be evac-
uated remotely by Incident Command. The radio trans-
mitter is located inside of the FireHawk M7 Power
Module.
EXTENDAIRE SYSTEM
The ExtendAire System, located on the user’s left chest,
enables two users to share a common air supply during
emergency escape. The users can couple the Firehawk
Second Stage Regulator from one user to the intermedi-
ate pressure manifold of the other user. Both users will
receive intermediate pressure air from the donor's first
stage regulator and cylinder. The duration of the remaining
air supply will be reduced by at least half.
The SCBA is approved by NIOSH without inter-connecting
two users to one apparatus. NIOSH does not certify
“buddy breathers”. Therefore, the attachment of the
receiver's regulator to the donor's apparatus voids the
NIOSH approval for both air masks.
RESCUE BELT
The MSA Fire Service Rescue Belt is a personal escape
system integrated into an FireHawk M7 Carrier and
Harness Assembly. The system is designed to provide the
user a means of escape from an elevated position. Use of
the Rescue Belt must be in accordance with the user’s fire
department procedures. Care and use instructions are
provided under a separate manual, P/N 10052748.

7. High Pressure Hose
a. Inspect the high pressure hose between the Audi-
Larm Alarm and the PR14 First Stage Regulator.
Look for cuts or severe abrasions. If damage is pre-
sent, replace the hose.
8. Cylinder and Valve Assembly
a. Air mask cylinders should be recharged as soon as
possible after use. Cylinders should not be stored
partially charged for two reasons:
• If used without recharge, the service life of the air
mask is reduced.
• The cylinder burst disc vents excess pressure if a
full cylinder is over exposed to fire or heat. If the
cylinder is not full, it may be damaged before the
burst disc vents.
b. If the cylinder is less than FULL (within 10% of
rated service pressure), recharge it before storage.
Cylinder air must be at least CGA Quality
Verification Level (Grade) D respirable air. In fire ser-
vice applications, MSA recommends breathing air
quality in accordance with NFPA 1989.
c. Inspect the cylinder valve for signs of damage. The
valve may be opened slightly to ensure it operates
properly. Be sure to fully close the valve.
d. Inspect the cylinder body for cracks, dents, weak-
ened areas, corrosive agents causing the fibers to
break or peel, or signs of heat-related damage. If
the cylinder is damaged return it to an MSA Service
Center.
e. Check the hydrostatic test date on the cylinder
approval sticker located on the cylinder neck.
Fiberglass composite cylinders must be tested
every three years. Carbon-wrapped and steel cylin-
ders must be tested every five years.
f. Ensure the needle and gauge face on the cylinder
valve gauge are clearly visible and that the gauge
stem is not bent.
It is also essential that the required inspections and tests
be performed on all air mask cylinders in accordance with
Department of Transportation (DOT) regulations. DOT reg-
ulations require that composite cylinders be retired from
service after the fifteenth year. This does not include cylin-
der valve assemblies that may be reused. Steel and alu-
minum cylinder service life is indefinite if proper inspec-
tion and hydrostatic test procedures are followed and they
indicate that the cylinder may remain in service. Contact
an MSA distributor or sales associate for more information
regarding this policy.
Note: ANSI Z88.5 recommends checking cylinder pres-
sure weekly. For maximum safety the cylinders should be
stored full or empty (pressure above ambient but less than
100 psi).
9. FireHawk M7 Carrier and Harness
a. Operate the latch wing on the cylinder band to
ensure that it opens and closes properly and that it
holds the cylinder securely. If the cylinder band and
latch is locked, the latch wing should not turn.
b. Inspect the back plate for cracks, weakened areas,
or signs of damage due to heat or chemical related
damage.
c. Inspect all harness components for cuts, tears,
abrasions, or signs of damage due to heat or chem-
ical related damage.
10. FireHawk M7 Control Module
a. Inspect the gauge hose and power cable for any
visible signs of damage.
b. Inspect for external cracks in the housing and
ensure the rubber cover is not damaged.
c. Ensure the buttons are not damaged or missing.
d. Ensure the gauge hose and power cable are
securely attached to the FireHawk M7 Control
Module.
11. FireHawk M7 Power Module
a. Inspect the FireHawk M7 Power Module housing for
external cracks and ensure that the FireHawk M7
Power Module, battery tube, and cylinder stop are
securely attached to the backplate.
b. Inspect the piezo emitters on both sides of the
FireHawk M7 Power Module. Ensure that the emit-
ter covers are not obstructed by dirt or debris.
c. Ensure that the power cable is securely attached to
the FireHawk M7 Power Module. The fitting on the
power cable should not be able to be unthreaded
by hand.
d. Remove the cap from the battery tube. Ensure that
the o-ring is properly installed on the battery cap, if
o-ring is missing, it must be replaced.

FIREHAWK M7 HUD
FIREHAWK M7 HUD FUNCTIONALITY
1. The FireHawk M7 HUD allows the user to see the
cylinder pressure while wearing the air mask. The
FireHawk M7 Control Module wirelessly transmits a
signal to the FireHawk M7 HUD (on the facepiece)
while the air mask is in use. The FireHawk M7 HUD
displays the cylinder pressure in one quarter cylinder
increments, by an LED pattern.
• As each quarter cylinder pressure has been
reached, a unique LED pattern will be displayed for
approximately 20 second before extinguishing. The
display can be refreshed by pressing and holding
the mode button (green) on the FireHawk M7
Control Module for approximately three seconds.
• When 25% of the rated service pressure has been
reached, a single flashing red LED will be displayed
and will continue to flash until the unit is turned off
or the cylinder has be refilled.
• The FireHawk M7 HUD must be within approximate-
ly 18 inches of the FireHawk M7 Control Module to
properly receive the signal being transmitted.
2. The FireHawk M7 HUD has a buddy light that flashes
17 TAL 708 (L) Rev. 1 - 10082858
USING THE AIR MASK

TAL 708 (L) Rev. 1 - 10082858
red when the air mask has reached 25% of the rated
service pressure. This buddy light is not visible to the
user while the air mask is in use.
3. When the user of the air mask remains motionless for
approximately 20 seconds, the PASS pre-alarm will
begin to sound. During this pre-alarm, the FireHawk
M7 HUD will display an orange LED, and this LED will
extinguish when full PASS alarm has been reached or
the pre-alarm has been reset.
4. When an evacuation command has been sent to the
user (if the optional FireHawk M7 Telemetry Module is
in use), the FireHawk M7 HUD will display an alternat-
ing red and orange LED until the evacuation has been
confirmed.
5. The FireHawk M7 HUD has a photo sensor that auto-
matically adjusts the brightness of the LEDs based on
the intensity of the ambient light measured outside of
the facepiece.
6. The FireHawk M7 HUD indicates a low battery condi-
tion by a single flashing yellow LED. When the
FireHawk M7 Power Module reaches a low battery
condition, a double flash of the yellow LED will be dis-
played in the FireHawk M7 HUD. If both the FireHawk
M7 HUD and FireHawk M7 Power Module have
reached a low battery condition, the FireHawk M7
HUD will display an alternating single and double flash
of the yellow LED. If this condition exists, return to
fresh air, and replace the batteries immediately. See

FIREHAWK M7 CONTROL MODULE THERMAL ALARM
The FireHawk M7 Control Module can monitor tempera-
ture conditions if the thermal alarm option is activated. If
the user is exposed to more than a pre-set limit of
time/temperature, the thermometer icon on the FireHawk
M7 Control Module display will flash and the FireHawk M7
Power Module will sound a tone every 3 seconds.
Although this thermal alarm provides an indication
that the time-temperature curve is exceeded, the
curve may not represent the threshold to injury due to
variations in individuals and the protective clothing
worn. Use this alarm as a reference only to increasing
time-temperature. Do not use as a substitute for stan-
dard operating procedures regarding escape from
time-temperature extremes. Failure to do so can result
in serious personal injury or death.
Chart 3 shows the FireHawk M7 Control Module thermal
alarm activation curve. The time/temperature limits corre-
spond to this graph. The thermal alarm sounds if the pre-
set limit exceeds the curve displayed on the graph. The
alarm will self-cancel depending on the severity of condi-
tions. This may occur even though the temperature is
above the thermal curve.

USING THE AIR MASK
The FireHawk M7 Control Module has the ability to
display calculated remaining service time counting
down to 0 psi (default) or 25% of the rated service
pressure. The user must determine which option has
been selected for the FireHawk M7 Control Module in
service. Failure to follow this warning can result in
serious personal injury or death.
Actual time remaining may be less than the calculated
time displayed. Increases in breathing rate may reduce
remaining time more than expected. Use time indica-
tor as general guide only. The time displayed is based
on the continuation of the average breathing rate over
the last three minutes. Increases in the breathing rate
after checking the displayed time may result in less
remaining time than anticipated. Failure to follow this
warning can result in serious personal injury or death.

COLD WEATHER OPERATION
Suggested Procedures for Cold Weather Operation
Moisture can cause problems in the air mask if it freezes.
However, moisture can cause freezing problems even if
the surrounding air is above freezing. Air flowing from the
cylinder through the first and second stage regulators
drops from cylinder pressure to close to atmospheric
pressure very quickly. This causes the air to expand and
creates a cooling effect. Although the surrounding tem-
perature may be warmer than 32°F, the temperature inside
the regulator may be lower. Any water inside could turn to
ice and restrict airflow.
1. To keep moisture from entering the mask mounted
regulator, keep the Firehawk Regulator in the belt
mounted regulator holder when not in use.
2. When the air mask is away from heat, water spray can
freeze on the Firehawk Regulator surface. Ice can
build up and bind the side buttons or the bypass
valve. Before entering or re-entering a hazardous
atmosphere, ensure the side buttons and bypass valve
are ice-free and operating properly. Periodically check
the bypass to be sure it is ice-free.
3. Moisture can enter through the cylinder valve or cou-
pling nut when cylinders are replaced on the air mask.
When replacing cylinders, ensure moisture or contami-
nation does not enter the system. Remove any ice
from these fittings. Wipe the coupling nut threads and
cylinder valve threads before installing a new cylinder.
Water can contaminate the system and freeze.
4. NIOSH certification requires a nosecup at tempera-
tures below 32°F. The nosecup reduces lens fogging
and must be used whenever freezing conditions are
encountered.
5. When cleaning the air mask, ensure water does not
enter the facepiece or Firehawk Regulator.
6. Thoroughly dry the facepiece and mask mounted reg-
ulator after cleaning and disinfecting. Follow
Confidence Plus® Cleaning Solution instructions.
Note: Fresh batteries must be installed in the FireHawk
M7 HUD and FireHawk M7 Power Module prior to storage
of the Air Mask at cold temperature for an extended peri-
od of time.

AUDI-LARM ALARM WITH URC ASSEMBLY OPERATION
OPERATION PRECAUTIONS FOR USING THE URC
(UNIVERSAL RESCUE CONNECTION) ASSEMBLY
1. The URC Assembly can only be used to fill approved
air mask cylinders.
2. The URC Assembly is not to be used as a "Buddy
Breather" such that two users are sharing the air sup-
plied by one air mask cylinder simultaneously doing so
will void NIOSH approval.
3. The user is responsible for the air supply, which must
meet the requirements of Compressed Gas
Association Specification ANSI/G-7.1, Quality
Verification Level (Grade) D Gaseous Air or better, with
a moisture dew point of not greater than -65°F
(24ppm water vapor, normal). In fire service applica-
tions, MSA recommends breathing air quality in accor-
dance with NFPA 1989. Pressures at the inlet of the
quick-fill hose must not exceed that of the air mask
(2216 psi or 4500 psi).
4. Using the 3000 psi URC Assembly to fill cylinders, the
cylinder can only be filled to 2216 psi. If the pressure
exceeds 2216 psi a relief valve in the URC Assembly
will vent at approximately 2525 psi or as low as 2400
psi. A 3000 psi cylinder can only be filled to 3000 psi
by using a secondary air supply; the 3000 psi URC
Assembly cannot be used for filling a 3000 psi cylinder.
5. The user also is responsible for connecting the quick-
fill hose to an appropriate secondary air supply.
6. The cylinder must be inspected for damage before
charging.
7. If filling cylinders in fresh air using the URC Assembly
topping off the cylinder is recommended after the
cylinder has cooled from initial fill. Topping off a cylin-
der after it has cooled will ensure proper service time.
All NFPA 1981:2007 approved air masks are equipped
with a URC Assembly (Universal Rescue Connection) fit-
ting. The URC Assembly is a male quick-fill inlet for use
by Rapid Intervention Crews for emergency filling opera-
tions. The system also includes an automatically resetting
pressure relief valve. The air mask can also be equipped
with a shoulder mounted Quick-Fill System, unless using
a 3000 psi URC Assembly, the 3000 psi URC Assembly
can not be used with Quick-Fill System. For additional
information on using the Quick-Fill System, refer to the
Quick-Fill System section of the manual.
• DO NOT use the URC Assembly as a "Buddy
Breather" such that two users are sharing the air
supplied by one approved air mask cylinder simul-
taneously; doing so will void NIOSH approval.
• The URC Assembly must be used by trained Rapid
Intervention Crews only using procedures devel-
oped for rapid intervention.
• DO NOT install a Quick-Fill System and 3000 psi
URC assembly on the same air mask. Combining
these assemblies on the same air mask will not
allow the relief valve in the 3000 psi URC Assembly
to open as designed. Failure to follow this warning
can result in serious personal injury or death.
•DO NOT transfill (be a donor) using a 3000 psi URC
Assembly. The 3000 psi URC Assembly has a
check valve that does not allow cylinders to trans-
fill (be a donor).
• Using the 3000 psi URC Assembly to fill cylinders,
the cylinder can only be filled to 2216 psi. If the
pressure exceeds 2216 psi a relief valve in the URC
Assembly will vent at approximately 2525 psi or as
low as 2400 psi. A 3000 psi cylinder can only be
filled to 3000 psi by using a secondary air supply;
the 3000 psi URC Assembly cannot be used for fill-
ing a 3000 psi cylinder.
• DO NOT lubricate the URC Assembly fittings. Do
not permit oil, grease, or other contaminants to
come in contact with the quick-fill fittings.
• The hose assemblies and fittings are designed to
be used with Quality Verification Level (Grade) D or
better air as defined by ANSI/CGA G-7.1.TRANS-
FILLING AIR FROM A SECONDARY AIR SUPPLY. In
fire service applications, MSA recommends breath-
ing air quality in accordance with NFPA 1989.
• DO NOT use any transfilling hose assembly or fit-
tings other than those supplied by MSA specifically
for the URC Assembly for filling operations.
Failure to follow the above warnings can result in seri-
ous personal injury or death.
Note: The URC Assembly may be used for transfill opera-
tions as described in this manual. Standard operating pro-
cedures should be developed for use of the URC Assembly.
The URC Assembly must be used only by qualified, trained
personnel who have carefully read and understood these
instructions, cautions, and warnings. NIOSH approvals of
SCBA from MSA are maintained while transfilling air only if
appropriate hose assemblies from MSA are used. URC
Assembly or hose assemblies and fittings are rated for a
maximum working pressure of 4500 psi. NIOSH approval
is maintained only when using the following hose assem-
blies: 485331, 802687, 802688, 802689, 802690, and
48332, for filling cylinders in IDLH atmospheres.
A secondary air supply stores compressed breathing air
until needed to refill air mask air cylinders. When transfill-
ing, the secondary air supply pressure must be greater
than air mask cylinder pressure. Examples of air supplies
include: cascade air cylinder refilling systems; high pres-
sure compressor systems with a fixed reservoir; or a
portable air system such as the RescueAire™ System.
DO NOT connect a high pressure air mask to a sec-
ondary air supply with a pressure greater than 4500
psi. The high pressure air mask is rated for a maxi-
mum working pressure of 4500 psi. Failure to follow
25 TAL 708 (L) Rev. 1 - 10082858
AUDI-LARM ALARM WITH URC ASSEMBLY OPERATION
the above warnings can result in serious personal
injury or death.
FILLING INSTRUCTIONS FOR USING THE URC
ASSEMBLY
For Rapid Intervention Crews:
Note: Rapid Intervention Crews should use a separate air
supply such as MSA’s RescueAire portable air supply sys-
tem to fill the air mask in an IDLH atmosphere.
NIOSH DOES NOT approve the use of the URC
Assembly to transfer air from the cylinder of one air
mask to another air mask. Failure to follow this warn-
ing can result in serious personal injury or death.
1. Connect the quick-fill hose to the air supply source or
donor air mask.
a. Push the female fitting of the hose on the male fit-
ting until it snaps in place. Pull on the hose to be
sure the fitting snapped into place.
b. Turn the air supply on.
If there are leaks from either female fitting, or along
the hose, depressurize the hose and correct the prob-
lem. Such leakage can result in increased fill time.
Failure to follow this warning can result in serious per-
sonal injury or death.
2. Attach the quick-fill hose to the URC Assembly or
shoulder mounted quick-fill fitting (optional).
a. Remove the rubber dust cap from the male inlet fit-
ting on the URC Assembly or quick-fill fitting. Be
sure that the cylinder valve is fully opened.
b. Remove the rubber dust cap from the female fitting
on the quick-fill hose.
c. Push the female fitting of the hose onto the male fit-
ting of the URC Assembly or quick-fill fitting until it
snaps in place. Pull on the hose to be sure the con-
nection is secure. Filling immediately begins when
the female fitting fully engages with the URC
Assembly or quick-fill fitting.
d. After approximately 45-60 seconds, the pressure
between the secondary air supply and the air mask
cylinder will be equal.
If serious leakage is noticed from either of the two
female fittings, or anywhere along the hose, discon-
nect the female fittings and return to fresh air immedi-
ately. Failure to follow this warning can result in seri-
ous personal injury or death.
Note: If the secondary air supply does not have a suffi-
cient volume of air, the air mask cylinder will not reach full
service pressure.
3. Compare the air mask cylinder gauge and the
FireHawk M7 Control Module gauge to the secondary
air supply pressure gauge reading. If the readings are
the same, pressure is equal.
4. To disconnect the quick-fill hose after transfilling, pull
back the gray sleeve on the female fitting of the quick-
fill hose. The hose fitting and the URC Assembly will
separate. A hiss or pop may be heard as the fittings
separate and the high pressure air is sealed off.
5. Immediately install the dust cover on the URC
Assembly or shoulder mounted quick-fill male fitting.
6. The air mask cylinder is ready for service if the cylin-
der pressure gauge needle is on the appropriate color
band.
ADDITIONAL INSTRUCTIONS
1. If in a fresh air environment and the dust cover will not
stay on the URC Assembly because air is leaking, cor-
rect the condition before using the air mask.
2. When filling the URC Assembly in an IDLH atmos-
phere and the dust cover will not stay on the URC
Assembly because air is leaking:
a. Immediately reconnect the quick-fill hose to seal off
the leak and return to fresh air.
b. If the hose cannot be reconnected, reach behind
and close the cylinder valve. The pressure in the air
mask will drop, and the leak will slow down.
c. Quickly replace the protective dust cap on the URC
Assembly or shoulder mounted quick-fill male fit-
ting. This will form a redundant seal.
d. Immediately open the cylinder valve and return to
fresh air.
If the Audi-Larm Alarm begins ringing, the FireHawk M7
HUD flashes a single red LED, or the alarm button on the
FireHawk M7 Control Module flashes red indicating that
the pressure in the cylinder has been reduced to 25% of
its maximum working pressure, return to fresh air immedi-
ately. The remaining service time must be used for escape
to fresh air.
Note: Only persons trained in MSA Maintenance are
authorized to repair or disassemble the URC Assembly. If
repairs are required, contact your nearest MSA office. Call
1-800-MSA-2222.

check that the latch engages with the proper slot on the
band. Re-install the cylinder and ensure that the latch
wing is fully tightened and flipped over. Do not use the air
mask if the cylinder is not held securely in the carrier.
10. Before installing the Audi-Larm Alarm, check that the
o-ring inside the Audi-Larm Alarm coupling nut is pre-
sent and free of damage. If the o-ring is damaged, it
must be replaced before the alarm is used.
11. Thread the Audi-Larm
Alarm coupling nut on
to the cylinder valve
thread form and hand-
tighten (no tools).
CHARGING CYLINDERS
A lightweight SCBA cylinder can become airborne solely
under the thrust of air from an inadvertedly opened cylin-
der valve. If a cylinder is removed from a horizontal shelf
by grasping the handwheel, the weight of the cylinder can
cause the cylinder to rotate downward causing the valve
to open slightly.
• Never carry a cylinder by the handwheel.
• Avoid dropping the cylinder or bumping the hand-
wheel.
• Use the handwheel only to open and close the
cylinder valve.
A valve could partially open causing the cylinder to
become an airborne projectile under its own pressure and
result in serious personal injury or death.
1. Remove from service if cylinder shows evidence of
exposure to high heat or flame: e.g., paint turned
28
TAL 708 (L) Rev. 1 - 10082858
REMOVING THE AIR MASK
to a brown or black color, decals charred or miss-
ing, gauge lens melted, or elastomeric materials
distorted.
2. Use this device only after receiving proper training
in its use. Use in accordance with this label and
MSA apparatus instructions.
3. To maintain NIOSH approval, the cylinder must be
fully charged with respirable air meeting the
requirements of the Compressed Gas Association
specification G-7.1 1989 for Quality Verification
Level (grade) D air or equivalent specification. In
fire service applications, MSA recommends breath-
ing air quality in accordance with NFPA 1989.
4. Do not use unless the cylinder is filled to the maxi-
mum working pressure.
5. Do not alter, modify, or substitute any components
without approval of the manufacturer.
6. Inspect frequently. Maintain according to manufac-
turer’s instructions. Repair only by properly trained
personnel.
Failure to follow these warnings can result in serious
personal injury or death.
SAFETY PRECAUTIONS FOR MSA SELF-CONTAINED
BREATHING APPARATUS CYLINDERS
Breathing apparatus cylinders should be fully recharged
as soon as possible after use.
Cylinders should not be stored partially charged:
1. If used partially charged, the duration of the air mask
is reduced.
2. The pressure relief device is only designed to protect
a fully charged cylinder from the effects of a fire.
For maximum safety, the cylinders should be stored full or
at a pressure above ambient but less than 100 psi.
Prior to recharging, cylinders must be examined externally
for evidence of high heat exposure, corrosion, or other
evidence of significant damage.
Additional information of value when performing external
and internal inspections of cylinders may be found in the
latest editions of CGA Publication C-6: "Standards for
Visual Inspection of Steel Compressed Gas Cylinders",
CGA Publication C-6.1: "Standards for Visual Inspection
of High Pressure Aluminum Compressed Gas Cylinders",
and/or CGA Publication C-6.2: "Guidelines for Visual
Inspection and Requalification of Fiber Reinforced High
Pressure Cylinders" available form the Compressed Gas
Association, Inc., 1725 Jefferson Davis Highway, Suite
1004, Arlington, VA 22202-4102.
If there is any doubt about the suitability of the cylinder
for recharge, it should be returned to a certified hydrostat-
ic test facility for expert examination and testing.
Always check to be sure the retest date is within the pre-
scribed period and that the cylinder is properly labeled to
indicate its gaseous service. New labels are restricted
items which are not available except through certified
hydrostatic test facilities.
When replacing cylinder valves or after the retesting of
cylinders, make sure the proper cylinder valve, burst disc,
and o-ring are installed prior to cylinder recharging.
Determine the maximum service pressure of the cylinder.
Type 3 AA (steel) cylinders that bear a plus (+) sign after
the latest retest date may be recharged to a pressure, i.e.
a cylinder stamped 3AA2015 with a plus (+) sign after the
test date may be recharged to 2216 psi. (this applies to
steel cylinders only). Steel cylinders without the plus (+)
sign stamped after the latest test date must be removed
from service. All other cylinders which are not 3AA type
shall be filled to the designated service pressure only (as
found on the DOT approval or stamping). For cylinders
manufactured under a U.S. DOT exemption (i.e., DOT-E-
#####), the exemption should be consulted and is avail-
able from the Associate Administrator for Hazardous
Materials Safety, Research and Special Programs
Administration, U.S. Department of Transportation, 400
7th Street, SW, Washington, D.C. 20590-0001.
Appropriately connect the cylinder to the filling system
and refill. Terminate the filling when the pressure reaches
the maximum service pressure and allow the cylinder to
cool to room temperature. If necessary, top-off the cylin-
der such that the service pressure is attained with the
cylinder at a temperature of 70°F. Close the valves on the
cylinder and the filling system and remove the cylinder.
Apply a leak solution to determine if there is any leakage
between the cylinder and the valve. If there is no leakage,
the cylinder is ready for use.
STORAGE
Do not store the air mask or spare cylinders within or near
an area where the air mask can or might be exposed to
any substances that will or might attack any part of the air
mask, causing the air mask to not perform as designed
and approved.
Prior to storing the air mask in a jumpseat, ensure there is
no interference between the air mask and the seat.
DO NOT drop the cylinder or bump the valve knob. An
unsecured cylinder can become an airborne projectile
under its own pressure if the valve is opened even
slightly. Failure to follow this warning can result in
serious personal injury or death.
Do not store the air mask for extended periods with the
batteries installed in the electronic components if the air

REMOVING THE AIR MASK
mask is not intended for service. If the air mask is in ser-
vice, ensure that the batteries in the electronic compo-
nents have an adequate charge. Do not store the air mask
with an empty or partially filled cylinder. Always install a
fully-charged cylinder so that the air mask is ready for
use. Complete Inspection and Cleaning and Disinfecting
Procedures outlined in this manual. Ensure the entire air
mask is clean and dry. Ensure the facepiece head harness
adjustment straps are fully extended. Place the complete
air mask in the storage case or suitable storage location
so it can be easily reached for emergency use.
For prolonged storage of the air mask, remove the batter-
ies from all electronic components to prevent battery cor-
rosion. Store the units in a cool, dry place.
Note: Fresh batteries must be installed in the FireHawk
M7 HUD and FireHawk M7 Power Module prior to storage
of the air mask at cold temperature for an extended peri-
od of time.

CLEANING AND DISINFECTING
CLEANING AND DISINFECTING
Depending on the cleaning policy adopted, either a desig-
nated person or the user should clean each device after
each use. ANSI standards suggest that users should be
trained in the cleaning procedure. Confidence Plus
Cleaning Solution (P/N 10009971) from MSA is recom-
mended. It cleans and disinfects in one operation. It
retains its germicidal efficiency in hard water to inhibit the
growth of bacteria. It will not deteriorate rubber, plastic,
glass, or metal parts. Refer to the label for user instruc-
tions.
• DO NOT use any cleaning substances that can or
might attack any part of the air mask.
• DO NOT use alcohol because it may deteriorate
rubber parts.
• If not rinsed thoroughly, cleaning agent residue
may irritate the wearer’s skin.
1. Preparing Solution
a. Follow the instructions with the Confidence Plus
Cleaning Solution.
b. If the Confidence Plus Cleaning Solution is not
used, wash in a mild cleaning solution, rinse thor-
oughly, and submerge in a germicide solution for
the manufacturer’s recommended time.
2. Clean and Disinfect the Facepiece
a. Remove the mask mounted regulator from the face-
piece.
b. Unthread the thumb screw of the FireHawk M7
HUD and remove the FireHawk M7 HUD from the
facepiece bracket.
c. Remove the Clear Command Communication
System (if used).
d. Thoroughly wash the facepiece (and nosecup) in the
cleaning solution. A soft brush or sponge can be
used to clean the soiled facepiece.
e. Rinse the facepiece and components in clean,
warm (110°F) water (preferably running and drain-
ing).
f. Clean the pressure-demand exhalation valve by
pressing in on the stem with a blunt object and
flushing it with clean water.
g. Allow the facepiece to air dry. Do not dry the parts
by placing them near a heater or in direct sunlight.
The rubber will deteriorate.
h. Operate the exhalation valve by hand to be sure it
works properly.
Note: Do not force-dry the parts by placing them in a
heater or in direct sunlight. The rubber will deteriorate.
When the facepiece is thoroughly dry, store the facepiece
in the plastic bag in which it was shipped.
3. In general, only the facepiece requires cleaning and
disinfecting after each use. If the air mask is soiled
(i.e. heavy smoke residue or dirt accumulation) use a
sponge damp with mild soap solution or use a
soft/medium bristle brush to remove deposits that
may interfere with normal operation of:
a. Harness (straps and buckles)
b. Cylinder Carrier (band and latch assembly)
c. Cylinder (handwheel, gauge, outlet connection)
d. Audi-Larm Alarm (bell and coupling nut connection)
e. FireHawk M7 HUD/FireHawk M7 Control
Module/FireHawk M7 Power Module
f. FireHawk M7 Control Module Gauge and LCD
Cover Lens
g. First Stage Regulator (PR14)
h. Firehawk Second Stage Regulator. Cover the outlet
of the Firehawk Regulator to prevent water, dirt, or
debris from entering.
4. Inspect the entire air mask as it is reassembled.
Follow the Inspection Instructions.
5. Re-attach the FireHawk M7 HUD
a. Insert the FireHawk M7 HUD into the facepiece
bracket.
b. Finger-tighten the thumbscrew.
6. Re-attach Clear Command Communication System (if
used).
7. Thoroughly dry the facepiece and Firehawk Regulator
after cleaning and disinfecting. The facepiece can trap
water, which could enter the regulator.

FLOW TEST AND OVERHAUL REQUIREMENTS
FLOW TEST AND OVERHAUL REQUIREMENTS
The Firehawk Regulator and Audi-Larm Alarm must be
flow tested and overhauled at specific time intervals.
These Maintenance Procedures must be performed by a
trained repairperson or at a certified service center.
Contact your MSA sales representative or call the MSA
Customer Service Center at 1-877-MSA-3473. They will
supply the information needed to meet these require-
ments.
Annual flow tests are stated as a requirement in NFPA
1852, Standard on Selection, Care, and Maintenance of
Open-Circuit Self-Contained Breathing Apparatus (SCBA),
2002 Edition, which further emphasizes their importance.
Although this standard relates to SCBA used in the fire
service, MSA requires that a flow test be performed at
least annually on all fire service and non-fire service SCBA
and combination respirators that use a pressure demand
regulator.
The required replacement/overhaul schedule for MSA air
masks is based on apparatus usage on an individual
basis. The frequency required for air mask overhaul
depends upon how often the apparatus is used. MSA air
masks must be overhauled based on the actual level of
usage of the air mask, rather than on time alone.
MSA air masks must be flow tested every year using an
MSA approved flow test device. The following table sum-
marizes MSA’s required frequency for overhaul and flow
testing: An overhaul kit (MSA P/N 10048942) is available.
MSA recommends the routine inspection of all elastomeric
materials including, but not limited to those in the Visual
Inspection and Functional Check section of this manual.
A decision to retire apparatus should be based on an air
mask’s performance data and whether that data meets
the specified level of performance as defined in mainte-
nance requirements from MSA.
*The unit of air mask use is defined as the consumption of
one entire cylinder of air. Example: If three cylinders of air
are used, the air mask would be considered to have been
used three times.
If an assessment of the air mask’s usage cannot be esti-
mated or determined, then the air mask shall be over-
hauled every three years.

QUICK-FILL SYSTEM OPERATION
QUICK-FILL SYSTEM OPERATION
The Quick-Fill System may be used for transfill operations
as described in this manual. Only qualified, trained per-
sonal Standard Operating Procedures should be devel-
oped for use of the Quick-Fill System.
PRECAUTIONS FOR USING QUICK-FILL SYSTEM
1. The Quick-Fill System can only be used to fill
approved air mask cylinders.
2. The Quick-Fill System is not to be used as a "Buddy
Breather" such that two users are sharing the air sup-
plied by one air mask cylinder simultaneously doing so
will void NIOSH approval.
3. The user is responsible for the air supply, which must
meet the requirements of Compressed Gas
Association Specification ANSI/G-7.1, Quality
Verification Level (Grade) D Gaseous Air or better, with
a moisture dew point of not greater than -65°F
(24ppm water vapor, normal). In fire service applica-
tions, MSA recommends breathing air quality in accor-
dance with NFPA 1989. Pressures at the inlet of the
quick-fill hose must not exceed that of the air mask
(2216 psi or 4500 psi).
4. Using the 3000 psi URC Assembly to fill cylinders, the
cylinder can only be filled to 2216 psi. If the pressure
exceeds 2216 psi a relief valve in the URC Assembly
will vent at approximately 2525 psi or as low as 2400
psi. A 3000 psi cylinder can only be filled to 3000 psi
by using a secondary air supply; the 3000 psi URC
Assembly cannot be used for filling a 3000 psi cylin-
der.
5. The user also is responsible for connecting the quick-
fill hose to an appropriate secondary air supply.
6. The cylinder must be inspected for damage before
charging.
7. If filling cylinders in fresh air using the Quick-Fill
System topping off the cylinder is recommended after
the cylinder has cooled from initial fill. Topping off a
cylinder after it has cooled will ensure proper service
time.
• DO NOT use a 3000 psi air mask with a 2216 psi air
mask cylinder.
• DO NOT install a Quick-Fill System on a 3000 psi
air mask. This combination will not allow the relief
valve in the 3000 psi URC Assembly to open as
designed.
• DO NOT use the Quick-Fill System as a "Buddy
Breather" such that two users are sharing the air
supplied by one approved air mask cylinder simul-
taneously; doing so will void NIOSH approval.
• DO NOT transfill (be a donor) using a 3000 psi URC
Assembly. The 3000 psi URC Assembly has a
check valve that does not allow cylinders to trans-
fill (be a donor).
•Using the 3000 psi URC Assembly to fill cylinders,
the cylinder can only be filled to 2216 psi. If the
pressure exceeds 2216 psi a relief valve in the URC
Assembly will vent at approximately 2525 psi or as
low as 2400 psi. A 3000 psi cylinder can only be
filled to 3000 psi by using a secondary air supply;
the 3000 psi URC Assembly can not be used for
filling a 3000 psi cylinder.
• DO NOT lubricate the quick-fill fittings.
• DO NOT permit oil, grease, or other contaminants
to come in contact with the quick-fill fittings.
• The quick-fill hose assemblies and fittings are
designed to be used with Quality Verification Level
(Grade) D or better air as defined by ANSI/CGA G-
7.1.TRANSFILLING AIR FROM A SECONDARY AIR
SUPPLY. In fire service applications, MSA recom-
mends breathing air quality in accordance with
NFPA 1989.
DO NOT use the Quick-Fill®System, URC Assembly, or
ExtendAire™ System accessories if there is any possi-
bility that the environment contains a CBRN warfare
agent. These air mask accessories are not approved
for use in atmospheres containing CBRN warfare
agents.
Failure to follow the above warnings can result in seri-
ous personal injury or death.
The Quick-Fill System must be used only by qualified,
trained personnel who have carefully read and understood
these instructions, cautions, and warnings. NIOSH
approvals of SCBA from MSA are maintained while trans-
filling air ONLY if appropriate quick-fill hose assemblies
from MSA are used. Quick-fill hose assemblies and fit-
tings are rated for a maximum working pressure of 4500
psi.
NIOSH approval is maintained only when using the follow-
ing hose assemblies: 485331, 802687, 802688, 802689,
802690, and 48332, for filling cylinders in IDLH atmos-
pheres.
DO NOT use any transfilling hose assembly or fittings
other than those supplied by MSA specifically for the
URC Assembly for filling operations. Failure to follow
this warning will void NIOSH approval and can result
in serious personal injury or death.
A secondary air supply stores compressed breathing air
until needed to refill air mask air cylinders. When transfill-
ing, the secondary air supply pressure must be greater
than air mask cylinder pressure. Examples of air supply
includes: cascade air cylinder refilling systems; high pres-
35 TAL 708 (L) Rev. 1 - 10082858
QUICK-FILL SYSTEM OPERATION
sure compressor systems with a fixed reservoir; and an air
mask air cylinder which is not installed on an air mask.
DO NOT use any transfilling hose assembly or fittings
other than those supplied by MSA specifically for the
URC Assembly for filling operations.
Failure to follow the above warnings can result in seri-
ous personal injury or death.
FILLING INSTRUCTIONS FOR QUICK-FILL SYSTEM
1. To connect the quick-fill hose to the secondary air
supply.
a. Turn the air supply on.
The following hoses can be used to connect to a sec-
ondary air supply.
If there are leaks from either female fitting, or along
the hose, depressurize the hose and correct the prob-
lem. Such leakage can result in increased fill time.
Failure to follow this warning can result in serious per-
sonal injury or death.
2. Attach the quick-fill hose to the URC Assembly or
shoulder mounted quick-fill fitting.
a. Remove the rubber dust cap from the male inlet fit-
ting on the URC Assembly or quick-fill fitting. Be
sure that the cylinder valve is fully opened.
b. Remove the rubber dust cap from the female fitting
on the quick-fill hose.
c. Push the female fitting of the hose onto the male fit-
ting of the URC Assembly or quick-fill fitting until it
snaps in place. Pull on the hose to be sure the con-
nection is secure. Filling immediately begins when
the female fitting fully engages with the URC
Assembly or quick-fill fitting.
d. After approximately 45-60 seconds, the pressure
between the secondary air supply and the air mask
cylinder will be equal.
Note: If the secondary air supply does not have a suffi-
cient volume of air, the air mask cylinder will not reach
maximum service pressure. After approximately 45-60
seconds, pressure between the secondary air supply and
the air mask cylinder will be equal.
3. Compare the air mask pressure gauge or ICM Unit
reading to the secondary air supply pressure gauge
reading. If the readings are the same, pressure is
equal.
4. To disconnect the quick-fill hose after transfilling, pull
the gray sleeve back. The hose fitting and the male fit-
ting will separate. A hiss or pop may be heard as the
fittings separate and the high pressure air is sealed
off.
5. Immediately install the dust cover on the male fitting.
6. The air mask cylinder is ready for service if the cylin-
der pressure gauge is on the corresponding color
band.
QUICK-FILL SYSTEM EMERGENCY OPERATIONS
1. When transfilling in fresh air and the dust cover will
not stay on the male fitting because air is leaking, cor-
rect the condition before using the air mask.
2. When transfilling in a contaminated atmosphere and
the dust cover will not stay on the male fitting because
air is leaking:
a. Immediately reconnect the quick-fill hose to seal off
the leak and return to fresh air.
b. If the hose will not reconnect, reach behind and
close the cylinder valve. Air pressure in the regulator
will drop, and the leak will slow down.
c. Quickly replace the protective dust cap on the male
fitting. This will form a redundant seal.
d. Open the cylinder valve and return to fresh air
immediately. The dust cover prevents dirt, water,
and debris from entering the fitting, and acts as a
redundant seal.

QUICK-FILL SYSTEM OPERATION
TRANSFILLING BETWEEN AIR MASK FROM MSA
(EMERGENCY BREATHING SYSTEM)
NIOSH DOES NOT approve the use of the URC
Assembly to transfer air from the cylinder of one air
mask to another air mask. Failure to follow this warn-
ing can result in serious personal injury or death.
Note: The air mask with the higher pressure reading is the
donor. The air mask with the lower pressure is the receiv-
er. Transfilling between users of air mask should be per-
formed only during life-threatening emergencies or simu-
lated training exercises. Both donor and receiver must
return to fresh air immediately following the procedure.
DO NOT transfill if the donor's audible alarm is ringing
or FireHawk M7 HUD /FireHawk M7 Control Module
are flashing. Failure to follow this warning can result in
shorter escape time to return to fresh air, causing seri-
ous personal injury or death.
The audible alarm begins ringing and heads-up display
system begins flashing to indicate that the pressure in the
cylinder has been reduced to 25% of its rated working
pressure. Remaining service time must be used for
escape to fresh air. If the donor's audible alarm begins
ringing or FireHawk M7 HUD/FireHawk M7 Control
Module begins flashing during transfilling, the donor
should disconnect and preserve his escape time.
1. If the donor's alarm is not ringing or FireHawk M7
HUD/FireHawk M7 Control Module are not flashing
and you have sufficient air to transfill air to a receiver,
(greater than 1000 psi for 2216 psi air masks and
greater than 2000 psi for 4500 psi air masks), follow
these steps.
a. Remove the 3 foot emergency transfill hose from its
protective pouch.
b. Remove the rubber dust cover from both female fit-
tings on the quick-fill hose assembly.
c. Remove the rubber dust cover from the male Quick-
Fill System fitting.
d. Push the female fittings on to the male fittings until
they click in place. Pull on the hose to be sure it
snapped in place.
If serious leakage is noticed from either of the two
female fittings, or anywhere along the hose, discon-
nect the female fittings and return to fresh air immedi-
ately. Failure to follow this warning can result in seri-
ous personal injury or death.
e. After approximately 30-60 seconds, pressure
between the air mask cylinders will be equal.
f. Disconnect the quick-fill hose from the air mask by
pulling the gray sleeve back on both ends. A hiss or
pop may be heard as the fittings separate and the
high pressure air is sealed off.
g. Immediately install the dust cover on the quick-fill
male fitting. The dust cover prevents dirt, water, and
debris from entering the fitting, and acts as a redun-
dant seal.
QUICK-FILL SYSTEM STORAGE
2. Preparing the Quick-Fill System for storage:
a. Press in on the center of the quick-disconnect dust
cap to release any pressure in the quick-fill hose.
b. Roll up the hose and place it in its protective pouch.
Note: Only persons trained in MSA Maintenance are
authorized to repair or disassemble the Quick-Fill System.
If repairs are required, contact your nearest MSA office.

EXTENDAIRE™ SYSTEM
INSTRUCTIONS FOR USE
GENERAL INFORMATION
Two air masks equipped with an ExtendAire System can
share a common air supply during emergency escape.
Users can couple the Firehawk Second Stage Regulator
from one user to the intermediate pressure manifold of the
other user. Both users will receive intermediate pressure
air from the donor's first stage regulator and cylinder. The
duration of the remaining air supply will be reduced by at
least half.
The SCBA is approved by NIOSH without inter-connecting
two users to one apparatus. NIOSH does not certify
“buddy breathers”. Therefore, the attachment of the
receiver's regulator to the donor's apparatus voids the
NIOSH approval for both air masks.
Air Hose: When used as a combination apparatus, the
device shall be supplied with respirable air through air
supply hose with a minimum length of 8 feet and maxi-
mum length of 300 feet within the pressure range of 85-90
psi. A maximum of 12 sections of straight or uncoiled air
supply hose may be used in making up the working
length of hose. When using coiled hose, a maximum of
six sections may be used and each section is considered
to be 50 feet long. Hose sections vary from 8 feet to 100
feet lengths. The air-line connection to the apparatus is to
be made through approved quick-disconnects only. The
purity of the air supply is the responsibility of the user. The
respirator is approved only when the air supplied meets
the requirements of the Compressed Gas Association
Specification G-7. 1989 quality verification level (Grade) D
for Gaseous Air.
Use this emergency escape breathing system for life
threatening emergencies and simulated training exer-
cises only. All other adequate means of escape must
be considered before using this device.
• During use the air supply, and consequently the
service time, is reduced approximately in half.
Before connecting two users make sure the air
supply is sufficient for both users to escape; other-
wise do not use the system.
• DO NOT use the system if the donor's audible
alarm is ringing.
• The NIOSH Approval for both apparatus are void
when this device is used, due to the difficulty in
maneuvering during escape. Exercise extreme care
while connected together. Mobility and range of
motion will be limited when donor's and receiver's
air masks are connected.
• Maintain slack in the air lines during maneuvering
and while connected together. DO NOT pull on the
hoses. Pulling on the rescue hose or the intermedi-
ate pressure hose could separate hoses from fit-
tings resulting in air leaks.
If the above measures cannot be followed or to pro-
vide greater escape protection, use the Quick-Fill
System. It maintains approval while transfilling and
does not exhibit the above hazards.
DO NOT use the Quick-Fill®System, URC Assembly, or
ExtendAire™ System accessories if there is any possi-
bility that the environment contains a CBRN warfare
agent. These air mask accessories are not approved
for use in atmospheres containing CBRN warfare
agents.
Failure to follow this warning can result in serious per-
sonal injury or death.
EMERGENCY ESCAPE BREATHING SYSTEM:
INSTRUCTIONS FOR USE
The ExtendAire System uses Snap-Tite quick-discon-
nects.
The Snap-Tite quick-disconnect has two significant fea-
tures.
1. It is single action to connect. The coupler is pushed
firmly over the plug to engage.
2. It is a locking type that requires two actions to discon-
nect.
a. Push the two sides of the quick-disconnect towards
each other. (The plug should advance into the cou-
pler end approximately 1/8".)
b. Slide the coupler’s outer sleeve away from the plug.
Pull the plug out of the coupler. Ensure that the
quick-disconnect plug on the manifold block is pro-
tected by the dust cap.
DO NOT install or attempt to use any hose assembly
or fitting other than those supplied by MSA for the
ExtendAire System. Failure to follow this warning can
result in serious personal injury or death.
PREPARATION FOR USE
BEFORE ENTERING A TOXIC ATMOSPHERE
1. Don the apparatus as described in the donning sec-
tion.
2. Ensure proper engagement of the Snap-Tite quick-dis-
connect coupling on the intermediate pressure hose
(at the manifold tee).

actual emergency conditions. Failure to follow this
warning can result in serious personal injury or death.
Hose Connection Procedure
1. Remove the dust cap from the quick-disconnect on
the donor's intermediate pressure manifold block.
2. Disconnect the receiver's second stage regulator hose
from their intermediate pressure manifold block by
disengaging the Snap-Tite quick-disconnect fitting.
3. Connect the receiver's second stage regulator hose to
the donor's manifold block.
a. Push the socket of the receiver's hose firmly over
the plug on the donor's manifold.
b. Check that the hose is properly routed and not tan-
gled with any other part of the apparatus (i.e. neck
strap, chest strap, etc.)
c. Check for full engagement by pulling at the quick-
disconnect to assure that the socket does not sepa-
rate from the plug. The apparatus of the donor will
supply air for emergency escape of the two individ-
uals. The duration of the remaining air supply will (at
least) be reduced in half.
4. Upon reaching a safe, non-toxic atmosphere, a stag-
ing area or performing other emergency egress proce-
dures, uncouple the receiver's hose at the quick-dis-
connect.
5. Replace the dust cap on the Snap-Tite plug.
The receiver's facepiece or regulator must be
removed upon disconnection from the donor's air sup-
ply. Failure to follow this warning can result in serious
personal injury or death from suffocation.

FIREHAWK M7 TELEMETRY MODULE
The FireHawk M7 Telemetry Module is designed to allow
the air mask to communicate with a remote base station
while in use. The FireHawk M7 Air Mask with FireHawk
M7 Telemetry Module installed will transmit vital statistics
such as cylinder pressure, temperature alarm (if thermal
alarm is enabled), service time remaining, and PASS alarm
to the base station. The base station also has the ability
to send an evacuation command to the air mask. The
FireHawk M7 Telemetry Module uses a special version of
the FireHawk M7 Control Module and FireHawk M7 Power
Module.
All basic functions of the air mask are the same as those
described in the During Use section of this manual except
for the following differences:
•Turning the FireHawk M7 Control Module On: When
the FireHawk M7 Control Module is activated in the
presence of a remote base station, the air mask auto-
matically begins to log on to that base station. When
the air mask is successfully logged on to the base sta-
tion, a radio link indicator will appear on the display of
the FireHawk M7 Control Module.
•Evacuation Signal: The air mask has the ability to
receive an evacuation signal from the remote base
station after it has been successfully logged on to the
base station. When an evacuation signal has been
sent by the base station, the “running man” icon will
appear, and flash, on the display of the FireHawk M7
Control Module and a unique audible alarm will be
emitted from the FireHawk M7 Power Module. The
evacuation signal must be manually confirmed by the
user by pressing the reset button (yellow) button twice
within approximately one second. This confirms the
evacuation signal by sending a confirmation signal
back to the base station. Once the evacuation signal
has been manually confirmed by the user, the “running
man” icon will stop flashing and remain on the display
until the FireHawk M7 Control Module has been
turned off.
•PASS Alarm: The PASS alarm will sound and function
normally with the FireHawk M7 Telemetry Module.
When the air mask emits a full PASS alarm, a signal is
automatically sent to the base station to alert Incident
Command.
•Thermal Alarm: When the air mask is exposed to
temperature conditions that warrant a thermal alarm, a
signal is automatically sent to the base station to alert
Incident Command.
•Low Battery: When the FireHawk M7 Power Module
reaches a low battery condition, a signal is automati-
cally sent to the base station to alert Incident
Command. A signal is not sent to the base station if
the FireHawk M7 HUD has a low battery condition.
•Data Log: The data logging feature of the FireHawk
M7 Control Module logs the status of the radio link to
the base station as well as any evacuation signals that
the air mask has received.
•Radio Link Indicator: The FireHawk M7 Control
Module has a radio link indicator located in the upper
left portion of the display. When this icon is displayed,
the air mask is logged on to a base station and within
range. When the radio link indictor is not shown, the
FireHawk M7 Control Module has not been logged on
to a base station or is out of the range of the base
station.
•Turning the FireHawk M7 Control Module Off: To
turn the FireHawk M7 Control Module off, press the
reset button (yellow) twice within approximately one
second. If the air mask is logged on to the base sta-
tion, there will be a delay between the two presses of
the reset button (yellow) and the actual shutdown of
the device. Before the FireHawk M7 Control Module
completely turns off, the base station must remove the
air mask from its registry. This causes the slight delay
between pressing the reset button (yellow) and the
actual shutdown of the device.
ID Tag (PN 10083875), for use with FireHawk M7
Telemetry Module
When the FireHawk M7 Telemetry Module is used with the
FireHawk M7 Air Mask, an ID Tag is used to assign a fire-
fighter’s name to the air mask. The name assigned to the
air mask will be displayed for that air mask on the base
station SCBA monitoring software. The name ID Tag must
be scanned into the FireHawk M7 Control Module at the
start of each shift (every 24 hours by default).
Note: The FireHawk M7 Interface Software can be used
to change this default to allow a name ID to be perma-
nently assigned to the air mask until a new name ID Tag
has been scanned.
A team ID Tag can also be used to assign a team/truck
and position to the air mask. If a team ID Tag has been
scanned into the FireHawk M7 Control Module but a
name ID Tag has not been scanned, the team ID will be
displayed on the SCBA monitoring software to provide
accountability even if the firefighter forgot to scan the
name ID Tag. Once a team ID Tag has been scanned into
the FireHawk M7 Control Module, the team ID will remain
with the air mask until another team ID Tag has been
scanned. If a team ID has not been assigned to the air
mask, the FireHawk M7 Control Module serial number will
be displayed as the firefighter’s ID when logged onto the
base station.
A base station ID can be used to assign a specific base
station ID to an air mask. When more than one base sta-
tion is present and actively monitoring at an incident, an
air mask with an assigned base station will search for the
preferred base station first to log on to, and if it does not
find the assigned base station within 20 seconds, it will
search for the first available base station and log on to it.
If a base station ID has not been assigned to the air mask,
it will log on to the first base station that it finds once the
41 TAL 708 (L) Rev. 1 - 10082858
APPENDIX
unit has been turned on. Once a base station ID tag has
been scanned into the FireHawk M7 Control Module, this
base station ID will remain with the air mask until another
base station ID tag has been scanned. The ID Tag has a
space for the user to place a label in which the ID infor-
mation can be written on the outside of the ID Tag for
easy identification. This space is located on the side of
the ID Tag opposite the approval label.
Before using the ID tag, inspect for damage or cracks in
the case. If damage is found, discard and replace the ID
tag.
Scanning the ID Tag into the FireHawk M7 Control
Module
Note: The FireHawk M7 Control Module must be turned
off to scan the ID Tag.
Prior to pressurization of the air mask and during inspec-
tion, the user can “tag in” by depressing and holding the
top mode button (green) until the word “data” appears in
the display. The FireHawk M7 Power Module will sound a
single beep when the FireHawk M7 Control Module enters
“data” mode. While “data” is displayed, hold the ID tag
as shown.
Correct ID Tag Orientation
The FireHawk M7 Power Module will sound a single beep
confirming that the ID data has been read and the word
“data” will disappear from the FireHawk M7 Control
Module display. If the word “data” disappears from the
FireHawk M7 Control Module display before the ID Tag
has been read, the FireHawk M7 Control Module has
timed out and the top mode button (green) must be
depressed and held again until “data” reappears.
The most recent ID Tag data that is stored in the FireHawk
M7 Control Module will be used as the identification for
the air mask on the base station PC screen. If no ID Tag
data has been assigned to the air mask, the FireHawk M7
Control Module serial number will be used as its identifi-
cation on the base station PC screen.
The ID tag is not designed to be taken into a fire. The
ID tag can also be used as an accountability tag.
Using the Base Station with the FireHawk M7
Telemetry Module
The FireHawk M7 Telemetry Module is designed to work
in conjunction with a remote base station unit. This base
station unit must be connected to a personal computer or
laptop before use. Refer to the Accountability System
Software instructions (PN 10068929) for more information.
Follow the PC or notebook computer manufacturer’s
recommendations for exposure to environmental con-
ditions to prevent damage to the system. Failure to do
so may cause system failure and the loss of monitor-
ing capability on the PC or notebook computer.
Using the M7 Firehawk Air Mask with FireHawk M7
Telemetry Module
Logging the Air Mask on to the Base Station
1. Turn on the FireHawk M7 Control Module on by open-
ing the cylinder valve or by pressing and holding the
alarm button.
2. A helmet icon representing the user of the air mask
will appear on the base station PC screen.
3. When the base station has established contact with
the air mask and all initial information has been
obtained, the signal strength indicator will appear in
the upper left corner of the FireHawk M7 Control
Module display.
4. Periodically check the status of the signal strength
indicator on the display of the FireHawk M7 Control
Module. If the signal strength indicator shows no bars,
this means that the air mask is out of range from the
base station. If this occurs, the signal strength indica-
tor will show 4 bars when the air mask returns within
range of the base station.
If the signal strength indicator does not appear on the
FireHawk M7 Control Module display, the base station
has not logged the unit on and can not monitor the
status of that firefighter.
Logging the Air Mask off of the Base Station
1. Once the user has returned to fresh air the FireHawk
M7 Control Module may be turned off.
2. Close the cylinder valve and purge the remaining air
from the system using the Firehawk Regulator bypass.
When the pressure falls below 200 psi, turn the
FireHawk M7 Control Module off (sleep mode) by
pressing the reset button twice in approximately one
second. (When the air mask is logged on to a base
station, there may be a delay between the two rapid
presses of the reset button and the actual shutdown
of the FireHawk M7 Control Module. Before the
FireHawk M7 Control Module completely turns off, the
base station must log off the air mask and send out a
final confirmation signal.
Evacuation Signal
If the air mask is logged on to the base station, the base
station will have the ability to send an evacuation signal to
the air mask. When an evacuation signal is sent to the air
mask, the FireHawk M7 Power Module will begin to beep
repeatedly and a flashing “running man” icon will appear
on the FireHawk M7 Control Module display. The evacua-

tion alarm will continue to sound until the reset button on
the FireHawk M7 Control Module has been pressed twice
within approximately one second. This confirms the evac-
uation by sending a confirmation signal back to the base
station.
