VISUAL INSPECTION AND FUNCTIONAL TESTS
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.
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 replacement of subassemblies must be
carried out by an MSA certified repair technician.
Failure to follow this warning will void NFPA and
NIOSH certifications and can result in serious person-
al injury or death.
FUNCTIONAL TESTS
Conduct the Following: Before Use, After Each Use,
and Monthly
1. Check that the Firehawk Responder Regulator and
facepiece can hold a negative pressure.
a. Close the cylinder valve and purge any air from the
system using the bypass knob on the Firehawk
Responder Regulator.
b. Hold the facepiece against the face to create an
effective seal.
c. Attach the Firehawk Responder Regulator to the
facepiece and inhale until the facepiece begins to
collapse against the face. (See “Installing the
FireHawk Responder Regulator” Section for instruc-
tion on installing FireHawk Responder Regulator).
Hold breath for approximately 10 seconds. Negative
pressure should be maintained and the facepiece
should remain collapsed against the face for the
entire 10 seconds.
d. Do not use the air mask if negative pressure cannot
be maintained in the facepiece. Return the Firehawk
Responder Regulator and facepiece to a certified
repairperson.
2. Check Firehawk Responder Regulator operation.
Note:
Firehawk Responder Regulator functional checks
must be conducted with a full cylinder. Check the pres-
sure gauge on the cylinder valve to verify that the cylinder
is full.
a. Push the release buttons on the side of the regula-
tor.
b. Ensure that the regulator bypass knob is fully
closed (clockwise).
c. Slowly open the cylinder valve to pressurize the air
mask. Ensure that the cylinder valve is completely
opened.
d. Open the Firehawk Responder Regulator bypass
knob (counter-clockwise). Ensure that air flows from
the regulator. Close the bypass knob (clockwise).
e. Attach the regulator to the facepiece. Ensure proper
regulator attachment by pulling on the regulator.
f. Don the facepiece or hold the facepiece against the
face to create an effective seal.
g. Inhale sharply to start air flow. Breathe normally.
Ensure proper regulator response. The regulator
should not make any unusual sounds including
whistling, chattering, or popping.
h. Remove the facepiece from the face. Ensure that air
flows freely. Push the regulator release buttons.
Ensure that air flow stops.
i. If the regulator fails to meet any of the above
checks, remove the air mask from service. Return
the regulator to a certified repairperson.
3. FireHawk M7 Responder HUD, FireHawk M7 Control
Module, FireHawk M7 Power Module, and Audi-Larm
Alarm
a. Verify proper function of the FireHawk M7
Responder HUD, FireHawk M7 Control Module,
FireHawk M7 Power Module, and Audi-Larm Alarm
by observing the FireHawk M7 Control Module
gauge and display when the alarms ring and tone.
Perform this test with a minimum cylinder pressure
of 1200 psi for 2216 psi air masks, 1800 psi for
3000 psi air masks, and 2000 psi for 4500 psi air
masks.
b. Pressurize the system by opening the cylinder
valve. Listen for the FireHawk M7 Power Module to
sound and for the Audi-Larm Alarm to ring briefly.
c. Look through the facepiece lens at the LED display
of the FireHawk M7 Responder HUD, the LEDs
must illuminate and show cylinder pressure (See
“FireHawk M7 Responder HUD Functionality”
Section for information on HUD LED patterns.
d. Ensure that the alarm button on the FireHawk M7
Control Module and the buddy lights on the
FireHawk M7 Power Module are slowly flashing
green.
