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. When the system is pressurized
above 25% of the rated service pressure, the alarm
enters the Monitor (normal) Mode. The unit remains in
Monitor mode until the user shuts off the cylinder air
and presses the reset button twice in quick succession.
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 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 the opaque
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 opaque lighted alarm button (green/red)
activates the full alarm mode with or without air
pressure.
•
•
•
•
o The top mode button (green) will refresh the receiver
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-emitting diodes (LEDs) behind the opaque 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 prealarm and flash rapidly when the device is in full
alarm.
The ICM Tx Unit operates using four standard AA
alkaline batteries and notifies the user when the batteries need to be replaced by emitting an audible beep
(1 beep every 5 seconds), displaying and empty battery icon on the LCD screen, and by flashing a YELLOW LED on the Nightfighter 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.

Tx Unit has read the ID data from a tag, that ID will remain
associated with all future sessions of the ICM Tx Unit until
another ID Tag has been swiped.
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.
Before using the ID tag, inspect for damage or cracks
in the case. If damage is found, discard and replace
the ID tag.

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.
The Quick-Fill System may be used for transfill operations
as described in this manual. Standard operating procedures 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.
WARNING
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.
WARNING
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 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. Failure to follow the above warnings may result in serious personal injury or death.
WARNING
Do not use the Quick-Fill System with 3000psig cylinders. Failure to follow the above warnings may result
in serious personal injury or death.
WARNING
An air mask using the 3000psig URC Assembly without Quick-Fill System can receive (be a Receiver)

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.
WARNING
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 assemblies 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 SECONDARY AIR SOURCE. Failure to follow the above
warnings may result in serious personal injury or
death.
WARNING
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 simultaneously; doing so will void NIOSH approval. 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 systems with a fixed reservoir; and an SCBA air cylinder
which is not installed on an SCBA.
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 transfilling 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.
WARNING
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.
NIOSH approval is maintained only when using the following hose assemblies:
485331, 802687, 802688, 802689, 802690, and 48332, for
filling cylinders in IDLH atmospheres.

PRECAUTIONS FOR USING QUICK-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 QuickFill 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.
Note: If the secondary air source does not have a sufficient 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 reading to the secondary air source pressure gauge reading. If the readings are the same, pressure is equal.
4. To disconnect the Quick-Fill System hose after transfilling, 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.
QUICK-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, correct 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 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. The dust cover prevents dirt,
