USING THE AIR MASK
alarm, the FireHawk M7 Power Module repeatedly
sounds two high-pitched tones followed by a buzz.
During full PASS alarm the alarm button on the
FireHawk M7 Control Module and the buddy lights on
the FireHawk M7 Power Module rapidly flash red.
• The PASS can be set into full alarm at any time (even
without air pressure) by pressing and holding the
alarm button on the FireHawk M7 Control Module.
• The PASS function uses red and green LEDs behind
the alarm button of the FireHawk M7 Control Module
and buddy lights on the FireHawk M7 Power Module
to display its status visually:
o Green LEDs start to flash when the cylinder valve is
opened and shows that the device is operational.
o Red LEDs flash slowly when the device is in PASS
pre-alarm and flash rapidly when the device is in full
PASS alarm.
o Red LEDs flash when the cylinder pressure is at or
below 25% of the rated service pressure.
• The four C alkaline batteries in the FireHawk M7
Power Module supply the FireHawk M7 Control
Module with power. The system notifies the user when
the batteries need to be replaced by emitting an audi-
ble beep (1 beep every 5 seconds) from the FireHawk
M7 Power Module, displaying and empty battery icon
on the display of the FireHawk M7 Control Module,
and by a double flashing yellow LED on the FireHawk
M7 HUD or I-HUD.
• The FireHawk M7 Control Module has a data logging
feature that records information about the air mask
while the FireHawk M7 Control Module is turned on.
This data log memory can be accessed using the
FireHawk M7 Module.
• The FireHawk M7 Interface Module contains an inter-
nal real time clock. This clock can be reset using the
FireHawk M7 Control Module. By default, the internal
clock is set to Eastern Standard Time.
Before placing the FireHawk M7 Air Mask in service,
verify that the internal clock is set to the appropriate
time as per the user’s geographic location. Failure to
do so can result in inaccurate data logging of the
FireHawk M7 Control Module.
The time may be viewed or changed using the FireHawk
M7 Interface Module. For additional instructions on using
the FireHawk M7 Interface Module refer to the FireHawk
M7 Interface Module Instructions (P/N 10088977).
USING THE FIREHAWK M7 CONTROL MODULE
(INTEGRATED PASS VERSION)
NOTE: Refer to Chart 3 for the various audible and visual
indicators.
FIREHAWK M7 CONTROL MODULE THERMAL ALARM
(INTEGRATED PASS VERSION)
The FireHawk M7 Control Module can monitor tempera-
ture conditions if the thermal alarm option is activated. If
the user is exposed to more than a pre-set limit of
time/temperature, the thermometer icon on the FireHawk
M7 Control Module display will flash and the FireHawk M7
Power Module will sound a tone every 3 seconds.
Although this thermal alarm provides an indication
that the time-temperature curve is exceeded, the
curve may not represent the threshold to injury due to
variations in individuals and the protective clothing
worn. Use this alarm as a reference only to increasing
time-temperature. Do not use as a substitute for stan-
dard operating procedures regarding escape from
time-temperature extremes. Misuse can result in seri-
ous personal injury or death.
Chart 4 shows the FireHawk M7 Control Module thermal
alarm activation curve. The time/temperature limits corre-
spond to this graph. The thermal alarm sounds if the pre-
set limit exceeds the curve displayed on the graph. The
alarm will self-cancel depending on the severity of condi-
tions. This may occur even though the temperature is
above the thermal curve.

Activation Curve
NOTE: This chart was generated from data obtained in a
laboratory setting and is for reference only. Conditions are
highly variable in an actual use scenario. Users of the
FireHawk M7 Control Module with the thermal alarm option
should develop procedures for the use of this feature.
DURING USE
NOTE: Refer to Chart 3 for the various audible and visual
indicators for the FireHawk M7 Control Module and
FireHawk M7 Power Module.
