DONNING
DO NOT use the air mask if the cylinder gauge and
FireHawk M7 pressure readings are not within 5%
(110/2216 psi, 150/3000 psi, 225/4500 psi) of full cylin-
der pressure. Send the unit to an MSA certified repair
person.
7. Check the Firehawk
Regulator’s bypass
operation. Grasp the
red knob and turn it
counter-clockwise.
Listen for airflow and
then turn it to the off
position.
8. Fully close the cylinder valve.
9. Listen for air leaks and watch the pressure indicators
on the FireHawk M7 Control Module or NightFighter
HUD Transmitter for 10 seconds.
DO NOT use the air mask if the pressure drops more
than 100 psi in ten seconds, The air mask must be
repaired; otherwise, reduced service life may result.
10. Crack the Firehawk Regulator bypass valve slowly to
bleed off pressure until the FireHawk M7 HUD or I-
HUD and FireHawk M7 pressure indicators drop
below:
530 psi-approximately (2216 psi system)
750 psi-approximately (3000 psi system)
1125 psi-approximately (4500 psi system)
At these pressures the FireHawk M7 HUD or I-HUD
should display a flashing red LED, the Audi-Larm Alarm
should ring continuously, and the alarm button on the
FireHawk M7 Control Module (integrated PASS version)
and the buddy lights on the FireHawk M7 Power Module
(integrated PASS version) should be flashing red.
11. When the system pressure falls below 200 psi, turn
the FireHawk M7 Control Module off by depressing
the reset button (yellow) two times within approxi-
mately one second. (integrated PASS version)
DO NOT use the air mask if the Audi-Larm Alarm fails
to ring or fails to continuously ring down to pressures
of 200 psi, or if the FireHawk M7 Control Module (inte-
grated PASS version) or FireHawk M7 HUD or I-HUD
fails to light properly. The air mask must be checked
and corrected for proper operation by an MSA trained
or certified repairperson before using. Misuse can
result in serious injury or death.
NOTE:
The FireHawk M7 HUD or I-HUD will automatically
turn itself OFF approximately 60 seconds after the air
mask has been depressurized. A red LED will flash until
the device turns off.
DONNING THE FACEPIECE
NOTE:
A nosecup is always required for use with this air
mask.
A nosecup must be installed in the facepiece. Misuse
can result in serious injury or death.
NOTE:
Before donning, ensure that the Firehawk
Regulator sealing ring is seated properly in its groove on
the outlet of the regulator and that it is not torn, gouged,
or nicked.
1. Loosen all the harness
straps. Grip the bottom
straps.
2. Insert chin into the
lower part of facepiece,
then pull the harness
back over the head.
