PR14 F RST 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 regulator incorporates a large, easily replaceable, sintered fil-
ter to capture particulates that may be in the air stream.
F REHAWK 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.
There are also two types of Firehawk Regulator intermediate
pressure hose connections, threaded and quick-connect.
CYL NDER AND VALVE ASSEMBLY
*as approved by NIOSH
The cylinder valve includes a metal valve body, threaded connec-
tion for filling and attachment of the Audi-Larm Alarm, hand-
wheel, 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.
AUD -LARM ALARM W TH URC ASSEMBLY
The Audi-Larm Alarm rings when there is approximately 33% of
the air mask’s rated service time remaining and when the cylin-
der valve is first opened, providing an audible 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 M7XT 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

charged for two reasons:
7MSA2211 (L) Rev. 8 - 10128861
"!
WARN NG

V SUAL NSPECT ON AND FUNCT ONAL TESTS
• If used without recharge, the available service time 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 ser-
vice pressure), recharge it before storage. Cylinder air must
be at least C A Quality Verification Level ( rade) D res-
pirable air. In fire service 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, weakened 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 shell. Fiberglass composite
cylinders must be tested every three years. Carbon-
wrapped and aluminum cylinders must be tested every
five years. Aluminum cylinder life is indefinite if proper
inspection and hydro test procedures are followed and
they indicate that the cylinder may remain in service.
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 per-
formed on all air mask cylinders in accordance with Department
of Transportation (DOT) regulations. DOT regulations require that
composite cylinders be retired from service after the fifteenth
year. This does not include cylinder valve assemblies that may be
reused. Aluminum cylinder service life is indefinite if proper
inspection 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 pressure
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 chemical
related damage.
10. Rescue Belt II
a. Refer to care and use instructions (P/N 10115063).
11. FireHawk M7XT Control Module (integrated PASS version)
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 M7XT Control Module.
e. Check both lens covers for dirt or moisture. If present refer
to the Cleaning and Disinfecting section, (item 3e).
12. FireHawk M7XT Power Module
a. Inspect the FireHawk M7XT Power Module housing for
external cracks and ensure that the FireHawk M7XT Power
Module, battery tube, and cylinder stop are securely
attached to the backplate.
b. Inspect the piezo emitters on both sides of the FireHawk
M7XT Power Module. Ensure that the emitter covers are
not obstructed by dirt or debris.
c. Ensure that the power cable is securely attached to the
FireHawk M7XT Power Module. The fitting on the power
cable should not be able to be unthreaded by hand.
13. 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 operations
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 replacement of subassemblies must be carried
out by an MSA certified repair technician. Failure to follow
this warning will void NFPA and N OSH certifications and
can result in serious personal injury or death.

play the cylinder pressure in one quarter cylinder increments,
by an LED pattern.
• As each quarter cylinder pressure has been reached, down
to 50%, a unique LED pattern will be displayed for approx-
imately 20 second before extinguishing. The display can
be refreshed by pressing and holding the mode button
(green) on the FireHawk M7XT Control Module for approx-
imately three seconds.
• Just before 33% 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 been refilled.
• The FireHawk M7 HUD or I-HUD must be within approxi-
mately 18 inches of the FireHawk M7XT Control Module to
properly receive the signal being transmitted.
2. Both the FireHawk M7 HUD and I-HUD have a buddy light
that flashes red when the air mask has reached 33% 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 or I-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.

and orange LED until the evacuation has been confirmed.
5. The FireHawk M7 HUD or I-HUD has a photo sensor that
automatically adjusts the brightness of the LEDs based on
the intensity of the ambient light measured outside of the
facepiece.
6. The FireHawk M7 HUD or I-HUD indicates a low battery con-
dition in either the HUD or FireHawk M7XT Power Module by
a flashing yellow LED. A user can confirm the power module
low battery indicator by viewing the low battery indicator on
the control module display. If this condition exists, return to
fresh air, and replace the batteries immediately. See

FUNCT ONAL TESTS
NOTE: Refer to the Visual Inspection and Functional Test section
of this manual.
Always test the FireHawk M7 HUD or I-HUD and the entire air
mask to be sure that the system operates properly before enter-
ing any hazardous atmosphere. DO NOT use this device unless it
passes all inspection and functional tests. Failure to follow this
warning can result in serious personal injury or death.
F REHAWK M7XT CONTROL MODULE FUNCT ONAL TY
• The FireHawk M7XT Control Module is assembled to the
gauge line hose and is connected to the FireHawk M7XT
Power Module by the power cable. The FireHawk M7XT
Control Module serves as the user interface with the air mask
and it also serves as the wireless transmitter for the FireHawk
M7 HUD or I-HUD.
• The FireHawk M7XT Control Module has three control but-
tons.
o The RESET/OFF button (yellow) on the side of the FireHawk
M7XT Control Module resets the PASS device from the full
alarm mode. It also shuts the unit off after the cylinder valve
has been closed and all pressure is bled from the system.
When the optional FireHawk M7XT Telemetry Module is
used, the Reset button allows the user to confirm an evacua-
tion command.
o The center lighted ALARM button (green/red) activates the
full PASS alarm with or without air pressure.
o The top MODE button (green) will refresh the display in
the FireHawk M7 HUD or I-HUD, activate the backlight on
the display of the FireHawk M7XT Control Module, set the
FireHawk M7 HUD or I-HUD to continuous display mode,
and toggle the FireHawk M7XT Control Module digital dis-
play mode between pressure remaining and calculated
service time remaining. When the FireHawk M7XT Control
Module is OFF, the mode button (green) can be used to
scan an ID Tag into the unit (when optional FireHawk
M7XT Telemetry Module is used).
• The FireHawk M7XT Control Module turns on automatically
when the user opens the air mask cylinder valve. As the sys-
tem pressure reaches approximately 250 psi, both visible and
audible alarms activate automatically, indicating that the unit
is functional (audible alarms are emitted from the FireHawk
M7XT Power Module located on the backplate). The unit
remains in monitor mode until the user closes the cylinder
valve, purges the system pressure, and presses the reset but-
ton (yellow) on the side of the FireHawk M7XT Control
Module two times within approximately one second.
• While the air mask is in use, if the user is motionless for
approximately 20 seconds, the PASS (FireHawk M7XT Control
Module and FireHawk M7XT Power Module) enters pre-alarm
with audible and visual alerts as indicated in Chart 1 (FireHawk
M7 HUD), Chart 2 (FireHawk M7 I-HUD), and Chart 3 (FireHawk
M7XT Power and Control Modules). Movement of the FireHawk
M7XT Control Module cancels the PASS pre-alarm.
• If the user remains motionless for 30 seconds (approximate-
ly), the PASS enters full alarm.
• The PASS can be set into full alarm at any time (even without
air pressure) by pressing and holding the alarm button on
the FireHawk M7XT Control Module.
• The PASS function uses red and green LEDs behind the alarm
button of the FireHawk M7XT Control Module and buddy
lights on the FireHawk M7XT Power Module to display its sta-
tus visually:
o reen LEDs start to flash when the cylinder valve is
opened and shows that the device is operational.
o Red LEDs flash slowly when the device is in PASS pre-
alarm and flash rapidly when the device is in full PASS
alarm.
o Red LEDs flash when the cylinder pressure is at or below
33% of the rated service pressure.
• The four C alkaline batteries in the FireHawk M7XT Power
Module supply the FireHawk M7XT Control Module with
power. The system notifies the user when the batteries need
to be replaced by emitting an audible beep (1 beep every 5
seconds) from the FireHawk M7XT Power Module, displaying
and empty battery icon on the display of the FireHawk M7XT
Control Module, and by a double flashing yellow LED on the
FireHawk M7 HUD or I-HUD.
• The FireHawk M7XT Control Module has a data logging fea-
ture that records information about the air mask while the
FireHawk M7XT Control Module is turned on. This data log
memory can be accessed using the FireHawk M7 Reader /
Tag Writer Interface Module.
• The FireHawk M7 Reader / Tag Writer Interface Module con-
tains an internal real time clock. This clock can be reset using
the FireHawk M7XT Control Module. By default, the internal
clock is set to Eastern Standard Time.
Before placing the FireHawk M7XT Air Mask in service, verify
that the internal clock is set to the appropriate time as per
the user’s geographic location. Failure to do so can result in
inaccurate data logging of the FireHawk M7XT Control
Module.
The time may be viewed or changed using the FireHawk M7
Reader / Tag Writer Interface Module. For additional instructions
on using the FireHawk M7 Reader / Tag Writer Interface Module
refer to the interface module instructions (P/N 10088977).
