NOTES

ICM TX UNIT FUNCTIONALITY
• The ICM Tx Unit is assembled to the gauge line hose
and serves as the transmitter for the NightFighter
Heads-Up Display System.
•The ICM Tx Unit turns on automatically when the user
opens the SCBA cylinder valve. As the pressure
reaches approximately 200 psig, both visible and
audible alarms activate automatically, indicating that
the unit is functional. The unit remains in Monitor
mode until the user shuts off the cylinder air and
presses the RESET (yellow) button twice in quick suc-
cession.
• If the user is motionless for approximately 20 seconds,
the ICM Tx Unit enters pre-alarm. During pre-alarm,
the device sounds 3 progressively louder tones and
the RED LED on the ICM Tx Unit flashes slowly. Also,
during pre-alarm, an ORANGE LED will be displayed
in the Nightfighter Heads-Up Display System Receiver.
Movement of the unit cancels the pre-alarm.
• If the user remains motionless for 30 seconds
(approx.), the ICM Tx Unit enters full alarm. During full
alarm, the PASS repeatedly sounds two high-pitched
tones followed by a buzz. During full alarm the RED
LED on the ICM Tx Unit also flashes rapidly.
• The ICM Tx Unit can be set into full alarm at any time
(even without air pressure) by pressing and holding the
ALARM button.
• The ICM Tx Unit has three control buttons.
o The RESET/OFF (yellow) button resets the device
from the full ALARM mode. It also shuts the unit off
after the cylinder valve is closed and all air pressure
is bled from the unit.
o The center lighted ALARM button (green/red) acti-
vates the full alarm mode with or without air pres-
sure.
o The top MODE button (green) will refresh the receiv-
er display, set the receiver to continuous mode, and
change the ICM Tx Unit digital display mode
between pressure remaining and calculated service
life remaining. When the ICM Tx Unit is OFF, the
MODE button (green) can be used to scan an ID
Tag into the ICM Tx Unit. See the “Using the ICM
Tx Unit” section for details.
• The PASS function uses RED and GREEN light-emit-
ting diodes (LEDs) behind the alarm button 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 pre-
alarm and flash rapidly when the device is in full
alarm. RED LEDs also flash when the SCBA pres-
sure is at or below 25% of the rated service pres-
sure.
• The ICM Tx Unit operates using four standard AA
alkaline batteries and notifies the user when the bat-
teries need to be replaced by emitting an audible beep
(1 beep every 5 seconds), displaying and empty bat-
tery icon on the LCD screen, and by flashing a YEL-
LOW LED on the Nightfighter Heads-Up Display
System Receiver Display.
• The ICM Tx Unit has a data logging feature that
records information about the SCBA while the ICM Tx
Unit is turned on. This data log memory can be
accessed using the ICM Tx Reader / ID Tag Writer
interface.
• The ICM Tx Unit contains an internal real time clock.
This clock can be reset using the ICM Tx Reader / ID
Tag Writer interface. By default, the internal clock is
set to Eastern Standard Time.

ICM TX UNIT THERMAL ALARM (THERMISTOR)
DEVICE TECHNICAL SPECIFICATIONS
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. Failure to do so can result
in serious personal injury or death.
The ICM Tx Unit can monitor temperature conditions if the
Thermal Alarm option is purchased. If the wearer is
exposed to more than a pre-set limit of time/temperature,
the unit will sound a tone every 3 seconds.

Chart 3 shows the ICM Tx Unit thermal alarm activation
curve. The time/temperature limits are based on the
curve. The thermal alarm sounds if the pre-set limit
exceeds the curve. The alarm will self-cancel depending
on the severity of conditions. This may occur even though
the temperature is above the thermal curve.
Chart 3: ICM Tx Unit Thermal Alarm 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
ICM Tx Unit with the thermal alarm option should develop
procedures for the use of this feature.
Optional ID Tag (PN 10058545), for use with ICM Tx
Unit
The purpose of the ID Tag is to associate a name ID or
truck and jump seat location with the ICM Tx Unit. Once
the ICM Tx Unit has read the ID data from a tag, that ID
will be associated with that ICM Tx Unit for the purpose of
organizing the data log. By default, a name ID will remain
associated with the ICM Tx Unit for 24 hours before expir-
ing (12 hours for devices manufactured before une
2006). The ICM Tx Unit can be configured to retain name
ID information until another name ID tag is read. For
instructions on changing this setting, refer to the ICM Tx
Unit Data Program Software Instructions (P/N 10067066).
The ID Tag has a space for the user to place a label in
which the ID information can be written on the outside of
the ID Tag for easy identification. This space is located
on the side of the ID Tag opposite the approval label.
Any label attached to the ID tag must be less than 4
square centimeters in total area; otherwise, the
Intrinsic Safety Approval is void. Failure to follow this
warning can result in serious personal injury or death.
Before using the ID tag, inspect for damage or cracks in
the case. If damage is found, discard and replace the ID
tag.

Unit
Prior to pressurization of
the SCBA and during
inspection, the user can
“tag in” by depressing and
holding the top mode but-
ton (green) until the word
“data” appears in the dis-
play. While “data” is dis-
played, hold the ID tag as
shown in the picture below.
The ICM will sound a single
beep confirming that the ID
data has been read. If the word “data” disappears before
the ID tag has been read, the ICM Tx Unit has timed out
and the top mode button (green) must be depressed and
held again until “data” reappears.
Correct ID Tag Orientation
The ID tag is not designed to be taken into a fire. The
ID tag can also be used as accountability tag.
Pressure Display
1. Periodically check the pressure indicated on the ICM
Tx Unit display. It will display either remaining cylinder
pressure or calculated remaining service life.
2. When the pressure reaches 25% of the rated service
pressure, the NightFighter Heads-Up Display Receiver
will display one flashing RED LED.

play between remaining cylinder pressure and calcu-
lated remaining service life.
The ICM Tx Unit has the ability to display calculated
remaining service life counting down to 0 psi or 25%
of the rated service pressure. The user must deter-
mine which option has been selected for the ICM Tx
Unit in service. Failure to follow this warning can
result in serious personal injury or death.
Actual time remaining may be less than the calculated
time displayed. Increases in breathing rate may reduce
remaining time more than expected. Use time indica-
tor as general guide only. The time displayed is based
on the continuation of the average breathing rate over
the last three minutes. Increases in the breathing rate
after checking the displayed time may result in less
remaining time than anticipated. Failure to follow this
warning can result in serious personal injury or death.
Starting Continuous Operations Mode

QUIC -FILL SYSTEM OPERATION
The Quick-Fill System may be used for transfill operations
as described in this manual. Standard operating proce-
dures should be developed for use of the Quick-Fill
System, unless using a 3000psi URC Assembly. The
3000psi URC Assembly cannot be used with Quick-Fill
system.
The 3000psi Operating System is NOT compatible with
a 2216psi SCBA Cylinder. Failure to follow the above
warnings may result in serious personal injury or
death.
DO NOT use the Quick-Fill System with 3000psig cylin-
ders. Failure to follow the above warnings may result
in serious personal injury or death.
An air mask using the 3000psig URC Assembly with-
out Quick-Fill System can receive (be a Receiver)
cylinder pressure through the 3000psig URC
Assembly. Do not use air mask with Quick-Fill System
and 3000psig URC Assembly on the same air mask.
Air mask with Quick-Fill System and 3000psig URC
Assembly on same air mask will not allow the relief
valve in the 3000psig URC Assembly to open as
designed. Failure to follow the above warnings may
result in serious personal injury or death.
The Quick-Fill System is not to be used as a "Buddy
Breather" such that two (2) users are sharing the air
supplied by one (1) approved SCBA cylinder simulta-
neously; doing so will void NIOSH approval. Failure to
follow the above warnings may result in serious per-
sonal injury or death.
The Quick-Fill System must be used only by qualified,
trained personnel who have carefully read and understood
these instructions, cautions, and warnings. NIOSH
approvals of SCBA from MSA are maintained while trans-
filling air ONLY if appropriate Quick-Fill System hose
assemblies from MSA are used. Quick-Fill System hose
assemblies and fittings are rated for a maximum working
pressure of 4500psig.
NIOSH approval is maintained only when using the follow-
ing hose assemblies:
485331, 802687, 802688, 802689, 802690, and 48332, for
filling cylinders in IDLH atmospheres.
For transfilling operations using the Quick-Fill System,
do not use any transfilling hose assembly or fittings
other than those supplied by MSA specifically for the
Quick-Fill System. Use of any other transfilling hose
assembly and/or fitting may result in serious personal
injury or death, and will void NIOSH approval. Failure
to follow the above warnings may result in serious
personal injury or death.
DO NOT Transfill (be a Donor) using a 3000psi URC
Assembly. The 3000psi URC Assembly has a Check
Valve that does not allow cylinders to Transfill (be a
Donor). Using the 3000psi URC Assembly to fill cylin-
ders, the cylinder can only be filled to 2216psig. If the
pressure exceeds 2216psig a relief valve in the URC
Assembly will vent at approximately 2525psig or as
low as 2400psig. A 3000psig cylinder can only be filled
to 3000psig by using a secondary air source; the
3000psi URC Assembly cannot be used for filling a
3000psig Cylinder. Failure to follow the above warn-
ings may result in serious personal injury or death.
DO NOT lubricate the Quick-Fill fittings. Do not permit
oil, grease, or other contaminants to come in contact
with the Quick-Fill fittings. The Quick-Fill hose assem-
blies and fittings are designed to be used with Quality
Verification Level (Grade) D or better air as defined by
ANSI/CGA G7.1. TRANSFILLING AIR FROM A SEC-
ONDARY AIR SOURCE. Failure to follow the above
warnings may result in serious personal injury or
death.
A secondary air source stores compressed breathing air
until needed to refill SCBA air cylinders. Secondary air
source pressure must be greater than air mask cylinder
pressure. Examples of air sources include: cascade air
cylinder refilling systems; high pressure compressor sys-
tems with a fixed reservoir; and an SCBA air cylinder
which is not installed on an SCBA.
DO NOT connect a Quick-Fill System equipped Low
Pressure SCBA to an unregulated secondary air
source with a pressure greater than 2216psig. The
Quick-Fill System equipped low pressure air mask is
rated for a maximum working pressure of 2216psig. As
an additional safety feature, the SCBA has a pressure
relief valve which automatically vents at 2525psig.
Failure to follow the above warnings may result in
serious personal injury or death.
17 TAL 709 (L) Rev. 4 - 10058881

QUIC -FILL SYSTEM OPERATION
DO NOT connect a High Pressure SCBA to a sec-
ondary air source with a pressure greater than
4500psig. The high pressure air mask is rated for a
maximum working pressure of 4500psig. Failure to fol-
low the above warnings may result in serious personal
injury or death.
PRECAUTIONS FOR USING QUIC -FILL SYSTEM
1. The Quick-Fill System can only be used to fill
approved SCBA cylinders.
2. The Quick-Fill System is not to be used as a "Buddy
Breather" such that two (2) users are sharing the air
supplied by one (1) SCBA cylinder simultaneously
doing so will void NIOSH approval.
3. The user is responsible for the air source, which must
meet the requirements of Compressed Gas
Association Specification ANSI/G-7.1, Quality
Verification Level (Grade) D Gaseous Air or better, with
a moisture dew point of not greater than -65°F
(24ppm water vapor, normal). Pressures at the inlet of
the Quick-Fill System hose must not exceed that of
the SCBA (2216psig or 4500psig).
4. Using the 3000psi URC Assembly to fill cylinders, the
cylinder can only be filled to 2216psig. If the pressure
exceeds 2216psig a relief valve in the URC Assembly
will vent at approximately 2525psig or as low as
2400psig. A 3000psig cylinder can only be filled to
3000psig by using a secondary air source; the 3000psi
URC Assembly cannot be used for filling a 3000psig
cylinder.
5. The user also is responsible for connecting the Quick-
Fill hose to an appropriate secondary air source.
6. The cylinder must be inspected for damage before
charging.
7. If filling cylinders in fresh air using the Quick-Fill
System topping off the cylinder is recommended after
the cylinder has cooled from initial fill. Topping off a
cylinder after it has cooled will ensure proper service
time.
FILLING INSTRUCTIONS FOR QUIC -FILL SYSTEM
1. To connect the Quick-Fill System hose.
a. Push the female fitting on the male fitting until it
snaps in place. Pull on the hose to be sure the fit-
ting snapped into place.
b. Turn the air source on.
If there are leaks from either female fitting, or along
the hose, depressurize the hose and correct the prob-
lem. Such leakage can result in increased fill time.
2. To attach the Quick-Fill System hose to the SCBA.
c. Remove the rubber dust cap from the male inlet fit-
ting on the SCBA. Be sure that the cylinder valve is
fully opened.
d. Remove the rubber dust cap from the female fitting
on the Quick-Fill System hose.
e. Push the female fitting on the male fitting until it
snaps in place. Pull on the hose to be sure the fit-
ting snapped into place. Transfilling begins when
the female fitting is snapped on the SCBA male fit-
ting.
Note: If the secondary air source does not have a suffi-
cient volume of air, the SCBA cylinder will not reach full
service pressure. After approximately 45-60 seconds,
pressure between the secondary air source and the SCBA
cylinder will be equal.
Cylinder temperature will increase by approximately
45°F. The pressure gauge may show FULL immediately
after transfilling, but cylinder pressure may decrease
by as much as 190psig after the cylinder cools to
room temperature. Actual service time may be
reduced accordingly.
3. Compare the SCBA pressure gauge or ICM Unit read-
ing to the secondary air source pressure gauge read-
ing. If the readings are the same, pressure is equal.
4. To disconnect the Quick-Fill System hose after trans-
filling, pull the gray sleeve back. The hose fitting and
the male fitting will separate. A hiss or pop may be
heard as the fittings separate and the high pressure air
is sealed off.
5. Immediately install the dust cover on the male fitting.
6. The SCBA cylinder is ready for service if the cylinder
pressure gauge is on the corresponding color band.
QUIC -FILL SYSTEM EMERGENCY OPERATIONS
1. If you are transfilling in fresh air and the dust cover will
not stay on the male fitting because air is leaking, cor-
rect the condition before using the SCBA.
2. If you are transfilling in a contaminated atmosphere
and the dust cover will not stay on the male fitting
because air is leaking:
a. Immediately reconnect the Quick-Fill System hose
to seal off the leak and return to fresh air.
b. If you cannot reconnect the hose, reach behind and
close the cylinder valve. Air pressure in the regula-
tor will drop and the leak will slow down.
c. Quickly replace the protective dust cap on the male
fitting. This will form a redundant seal.
d. Open the cylinder valve and return to fresh air
immediately. The dust cover prevents dirt, water
and debris from entering the fitting and acts as a
redundant seal.

QUIC -FILL SYSTEM OPERATION
TRANSFILLING BETWEEN SCBA FROM MSA
(EMERGENCY BREATHING SYSTEM)
Note: The SCBA with the higher pressure reading is the
donor. The SCBA with the lower pressure is the receiver.
Transfilling between users of SCBA should be performed
only during life-threatening emergencies or simulated
training exercises. Both donor and receiver must return to
fresh air immediately following the procedure.
DO NOT transfill if the donor's audible alarm is ringing
or NightFighter Heads-Up Display System/ ICM Unit
Gauge are flashing. Failure to follow this warning may
result in shorter escape time to return to fresh air,
causing serious personal injury or death.
The audible alarm begins ringing and NightFighter Heads-
Up Display System begins flashing to indicate that the
pressure in the cylinder has been reduced to 25% of its
rated working pressure. Remaining service time must be
used for escape to fresh air. If the donor's audible alarm
begins ringing or NightFighter Heads-Up Display
System/ICM Unit Gauge begins flashing during transfilling,
the donor should disconnect and preserve his escape
time.
1. If the donor's alarm is not ringing or NightFighter
Heads-Up Display System/ICM Unit Gauge are not
flashing and you have sufficient air to transfill air to a
receiver, (greater than 1000psig for Low Pressure
SCBA and greater than 2000psig for High Pressure
SCBA), follow these steps.
a. Remove the 3 foot emergency transfill hose from its
protective pouch.
b. Remove the rubber dust cover from both female fit-
tings on the Quick-Fill System hose assembly.
c. Remove the rubber dust cover from the male Quick-
Fill System fitting.
d. Push the female fittings on to the male fittings until
they click in place. Pull on the hose to be sure it
snapped in place.
If serious leakage is noticed from either of the two
female fittings, or anywhere along the hose, discon-
nect the female fittings and return to fresh air immedi-
ately. Failure to follow this warning may result in seri-
ous personal injury or death.
e. After approximately 30-60 seconds, pressure
between the SCBA cylinders will be equal.
f. Disconnect the Quick-Fill System hose from the
SCBA by pulling the gray sleeve back on both ends.
A hiss or pop may be heard as the fittings separate
and the high pressure air is sealed off.
g. Immediately install the dust cover on the Quick-Fill
System male fitting. The dust cover prevents dirt,
water, and debris from entering the fitting and acts
as a redundant seal.
QUIC -FILL SYSTEM EMERGENCY OPERATIONS
1. If the dust cover will not stay on the male fitting
because air is leaking:
a. Immediately reconnect the Quick-Fill System hose
to seal off the leak and return to fresh air.
b. If you cannot reconnect the hose, reach behind and
close the cylinder valve. Air pressure in the regulator
will drop and the leak will slow down.
c. Quickly replace the protective dust cap on the male
fitting. This will form a redundant seal.
d. Open the cylinder valve and return to fresh air
immediately.
2. Preparing the Quick-Fill System for Storage:
a. Press in on the center of the quick-disconnect dust
cap to release any pressure in the Quick-Fill System
hose.
b. Roll up the hose and place it in its protective pouch.
Note: Only persons trained in MSA Maintenance are
authorized to repair or disassemble the Quick-Fill System.
