USING THE AIR MASK
PRECAUTIONS DURING USE
NOTE: If the breathing apparatus or any component fails,
malfunctions, or becomes damaged, contact MSA at 1-
800-MSA-2222 [1-800-672-2222] or email customer ser-
vice at info@MSAnet.com. SCBA products may be con-
sidered hazardous material. In addition, U.S. Department
of Transportation exceptions and approvals may apply to
SCBA products. Please contact customer service at
1-800-MSA-2222, or visit www.MSAnet.com/prism, for
more information.
Periodically check the pressure indicated on the FireHawk
M7 chest mounted pressure indicator.
•
Air flow in the air mask is reduced: Immediately open
the Firehawk Regulator bypass. Immediately return to
fresh air.
• Air mask free-flows: Immediately return to fresh air.
• Audi-Larm Alarm Rings: Immediately return to fresh
air.
• FireHawk M7 HUD or I-HUD low pressure indicator
lights and flashes red: Immediately return to fresh air.
• FireHawk M7 Control Module (integrated PASS ver-
sion) alarm button flashes red: Immediately return to
fresh air.
Periodically check the pressure indicated on the FireHawk
M7 HUD or I-HUD and FireHawk M7 chest mounted pres-
sure indicator during use. The FireHawk M7 Control
Module continually displays the cylinder pressure while
the FireHawk M7 HUD or I-HUD indicates when each
quarter of the total cylinder pressure has been reached for
20 seconds. When the needle on the FireHawk M7 chest
mounted pressure indicator reaches the red zone on the
gauge face the Audi-Larm Alarm will begin ringing, the
FireHawk M7 HUD or I-HUD will display a flashing red
LED, and the alarm button on the FireHawk M7 Control
Module (integrated PASS version) and buddy lights on the
FireHawk M7 Power Module (integrated PASS version) will
flash red. When the Audi-Larm Alarm starts ringing or
when the pressure reaches approximately 25% of the
rated service pressure, return to fresh air.
The FireHawk M7 HUD or I-HUD, FireHawk M7 Control
Module (integrated PASS version), and Audi-Larm Alarm
indicate when cylinder pressure drops below these
approximate values:
530 psi-approximately (2216 psi system)
750 psi-approximately (3000 psi system)
1125 psi-approximately (4500 psi system)
When the FireHawk M7 HUD or I-HUD, FireHawk M7
Control Module (integrated PASS version), or Audi-Larm
Alarm indicates 25% cylinder pressure, immediately return
to fresh air.
NOTE: Air mask service life is greatly reduced when the
Firehawk Regulator bypass is used.
Leave the contaminated area immediately if:
• Breathing becomes difficult
• Dizziness or other distress occurs
• You taste or smell the contaminant
• You experience nose or throat irritation
• SCBA not functioning according to the
instructions or training
Misuse can result in serious injury or death.
NOTE: See NIOSH Approval Label, Inserted in the Users
Instructions for complete list of CAUTIONS and LIMITA-
TIONS for the respirator.
Misuse or abuse of the FireHawk M7 HUD or I-HUD,
the FireHawk M7 Control Module, FireHawk M7 Power
Module, NightFigher HUD Transmitter or the equip-
ment to which they are attached, or using this equip-
ment in a manner or situation not intended by the
manufacturer, may result in damage to the equipment
or may result in personal injury or death to user or
persons dependent on the user or damage to the
equipment.
• Always inspect the FireHawk M7 HUD or I-HUD,
FireHawk M7 Control Module, NightFighter HUD
Transmitter and FireHawk M7 Power Module for
damage before use. If damage is found, immedi-
ately remove the device from service.
• DO NOT alter these components. Altering will void
the Intrinsic-Safety rating and may affect the
Intrinsic-Safety of the device.
FIREHAWK M7 HUD OR I-HUD
FireHawk M7 HUD or I-HUD Functionality
NOTE: The M7 I-HUD is not compatible with the
NightFighter HUD Transmitter.
1. The FireHawk M7 HUD or I-HUD allows the user to
see the cylinder pressure while the air mask is in use.
The FireHawk M7 Control Module wirelessly communi-
cates with the M7 HUD or I-HUD (integrated PASS
version). The NightFighter HUD Transmitter wirelessly
communicates with the M7 HUD (without integrated
PASS version). Both the FireHawk M7 HUD and I-HUD
display the cylinder pressure in one quarter cylinder
increments, by an LED pattern.
• As each quarter cylinder pressure has been
reached, a unique LED pattern will be displayed for
approximately 20 second before extinguishing. The
display can be refreshed by pressing and holding
the mode button (green) on the FireHawk M7
