VISUAL INSPECTION AND FUNCTIONAL TESTS
14. NightFighter HUD Transmitter (without integrated
PASS version)
a. Inspect the transmitter. Look for cracks or other
signs of damage, which could allow contaminants
to enter the module housing.
b. Reassemble the transmitter (see instructions on
replacing batteries in the NightFighter HUD
Transmitter).
15. 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 NIOSH certifica-
tions and can result in serious personal injury or
death.
FUNCTIONAL TESTS
Conduct the Following: Before Use, After Each Use, and
Monthly
1. Check that the Firehawk 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
Regulator.
b. Hold the facepiece against the face to create an
effective seal.
c. Attach the Firehawk Regulator to the facepiece and
inhale until the facepiece begins to collapse against
the face. 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
Regulator and facepiece to a certified repairperson.
2. Check Firehawk Regulator operation.
NOTE: Firehawk Regulator functional checks must be
conducted with a full cylinder. Check the pressure 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. Observe the LED display of the FireHawk M7 HUD
or I-HUD. Ensure that the cylinder valve is com-
pletely opened.
d. Open the Firehawk 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 HUD or I-HUD, FireHawk M7 Control
Module, FireHawk M7 Power Module, NightFighter
HUD Transmitter, and Audi-Larm Alarm.
a. Air masks with integrated PASS
1. Verify proper function of the FireHawk M7 HUD
or I-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.
2. 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.
3. Observe the LED display of the FireHawk M7
HUD or I-HUD. The LEDs must illuminate and
correspond to the system pressure.
4. 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.
5. Allow the FireHawk M7 Control Module to
remain motionless for approximately 20 sec-
onds. Listen for the FireHawk M7 Power Module
to sound the low volume repeated tones of the
PASS pre-alarm. Verify that the alarm button on
the FireHawk M7 Control Module and the buddy
lights of the FireHawk M7 Power Module are
slowly flashing red. Also verify that the orange
LED is displayed in the FireHawk M7 HUD or I-
HUD. Ensure that the FireHawk M7 Control
Module remains motionless until the full PASS
alarm activates. Listen for the FireHawk M7
Power Module to sound the loud PASS alarm.
Look for the alarm button on the FireHawk M7
Control Module and the buddy lights on the
FireHawk M7 Power Module to rapidly flash red.
6. Reset the PASS alarm by pressing the reset but-
ton (yellow) on the side of the FireHawk M7
