DONNING
7. Check the Firehawk
Responder 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 gauge and
display on the FireHawk M7 Control Module 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 Responder Regulator bypass
valve slowly to bleed off pressure until the FireHawk
M7 Responder HUD and FireHawk M7 Control Module
displays 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 Responder HUD
should display a flashing red LED, the Audi-Larm Alarm
should ring continuously, and the alarm button on the
FireHawk M7 Control Module and the buddy lights on the
FireHawk M7 Power Module 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.
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 or
FireHawk M7 Responder HUD fails to light properly.
The air mask must be checked and corrected for
proper operation by an MSA trained or certified repair-
person before using. Failure to follow this warning can
result in serious personal injury or death.
Note:
The FireHawk M7 Responder HUD will automatical-
ly turn itself OFF approximately 60 seconds after the air
mask has been depressurized. A single red LED will flash
until the device turns off.
DONNING THE FACEPIECE
DO NOT wear eyeglasses under the facepiece. The
temples or sidebars on eyeglasses will prevent an air-
tight seal. If you must wear glasses, install an
approved spectacle kit listed on the NIOSH approval
label. Failure to follow this warning can cause inhala-
tion of contaminated air, resulting in serious respirato-
ry injury or death.
Note:
Before donning, ensure that the Firehawk
Responder 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.
3. Pull the back of har-
ness downward until
centered at the back of
the head.
