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
Responder 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 RESPONDER SECOND STAGE
REGULATOR
The Firehawk Responder Regulator is a pressure-demand
regulator, which maintains a positive pressure in the face-
piece while the air mask is in use.
The Firehawk Responder Regulator attaches to the face-
piece via a push-to-connect feature.
The FireHawk Responder Regulator includes a pneumatic
plug that connects to the Ultra Elite Responder facepiece.
When the SCBA is pressurized, the pneumatic plug acti-
vates the pressure-demand exhalation valve.
The Firehawk Responder Regulator has a quick-connect
connection to the intermediate pressure hose.

DESCRIPTION
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 Responder 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 emergency filling of the SCBA or during transfill opera-
tions. 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 arrier and harness assembly as a
verti al raising or lowering devi e. Failure to follow
this warning an 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 RESPONDER FACEPIECE
The facepiece includes a dual-mode exhalation valve.
When the facepiece is not connected to the FireHawk M7
Responder regulator, the exhalation valve operates as a
demand exhalation valve. When the facepiece is connect-
ed to a pressurized FireHawk M7 Responder regulator, the
exhalation valve operates as a pressure-demand exhala-
tion valve.
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 Responder
Regulator.
The facepiece has a speaking diaphragm for clear com-
munication.
The facepiece has a nose cup with a drink tube and can
be used with the SpeeD-ON® Head Harness.
The facepiece has a plug for the side port that must be
attached during use.
DO NOT use this fa epie e without the fa epie e plug
installed. Failure to follow this warning an result in
serious personal injury or death.
FIREHAWK M7 RESPONDER HUD
The FireHawk M7 Responder HUD, located on the Ultra
Elite Facepiece allows a user to see cylinder pressure in
one quarter cylinder increments, PASS pre-alarms, battery
status, 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.

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
M7 Control Module via the power cable.
OPTIONAL FIREHAWK M7 RESPONDER AIR MASK
COMPONENTS
CLEAR COMMMAND COMMUNICATION SYSTEM
The Clear Command Communication System is an elec-
tronic speech projection system available with either an
amplifier or an amplifier with radio interface connection.
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 at the end of the interme-
diate pressure line, enables two users to share a common
air supply during emergency escape. The users can cou-
ple the Firehawk Responder 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-connect-
ing 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, PN 10052748.

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. MSA rec-
ommends 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).

e. Inspect the inside of the battery tube. Ensure that
the battery terminals are not corroded and that the
tube if free of moisture and debris.
f. Replace the battery cap on the battery tube.
12. Record Keeping
a. Following inspection, the date and initials of the
designated inspector should be recorded on an
inspection tag. A more detailed record of the opera-
tions performed can be noted on an inspection and
maintenance log, available from MSA. When the
inspection data has been recorded, the air mask is
ready for use.
All repair and repla ement of subassemblies must be
arried out by an MSA ertified repair te hni ian.

SIZE SELECTION
Regardless of facial dimensions and respirator sizing
charts, an actual respirator fit test, either qualitative or
quantitative must be performed to ensure the correct res-
pirator size selection.
Fit test the respirator size relative to your facial features
and dimensions. The Safety Administrator or Program
Manager might assist in selecting the initial size to try.
Carefully don the mask and conduct a negative pressure
seal test. See donning instructions for procedure.
If the facepiece does not pass the negative pressure seal
test or feels uncomfortable, try the next nearest size rela-
tive to your face.
Passing the negative pressure seal test does not verify the
size is correct. The size selected must be verified by suc-
cessfully passing a Respirator Fit Test, either qualitative or
quantitative. If the respirator passes a negative pressure
seal test but DOES NOT pass a Respirator Fit Test, try the
next nearest size.
Once the proper size is selected, the respirator must pass
a negative pressure seal test every time the facepiece is
donned to ensure proper fit before using the respirator.
If other than facial seal leakage is detected, the condition
must be investigated and corrected before another test is
made.
The facepiece must also pass the negative pressure seal
test before the user attempts to enter a toxic atmosphere.
The facepiece will not furnish protection unless all inhaled
air is drawn through the SCBA.
RESPIRATOR FIT TEST
The user must perform a respirator fit test
(Quantitative Test or Qualitative Test) and follow all
warnings and limitations spe ified. Failure to do so
an result in serious personal injury or death.
A qualitative or quantitative respirator fit test must be car-
ried out routinely for each wearer of this respirator to
determine or confirm the amount of protection that the
respirator provides. The fit test method chosen may
impact the maximum use concentration.
Quantitative Test – If a quantitative fit test is used, a fit
factor of at least 500, based on ambient aerosol fit test
methods or equivalent, is required before any type of res-
pirator is assigned to an individual.
Qualitative Test – If a qualitative fit test is used, only vali-
dated protocols are acceptable. The individual must pass
a test designed to assess a fit factor of at least 500.
When this fa epie e is used with the FireHawk M7
Responder APR, a fit fa tor of at least 2000 is required
for Quantitative or Qualitative test. Failure to do so
an result in serious personal injury or death.
Respirator fit tests are explained fully in the American
National Standard Practices for Respiratory Protection,
ANSI Z88.2-1992 which is published by the American
National Standards Institute, 11 West 42nd Street, New
York, New York, 10036 and Occupational Safety and
Health Standards, OSHA 1910.134, which is published by
the Occupational Safety and Health Administration, 200
Constitution Avenue, NW, Washington DC, 20210.
Using the Drink Tube for Fit Testing
The drink tube can be used for fit testing.
To use the drink tube for fit testing, perform the following:
1. Remove the nosecup from the facepiece.
2. Place the mouth-bit
between the lens
receptacle and speak-
ing diaphragm retainer.
3. Perform fit test.
Be sure the mouth bit does not onta t the fa e dur-
ing fit testing. Failure to do so an result in false pro-
te tion fa tor readings.
