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

udible alarms activate automatically, indicating that

he unit is functional. When the system is pressurized

bove 25% of the rated service pressure, the alarm

a 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

nto the ICM Tx Unit. See the “Using the ICM Tx

nit” section for details.

The PASS function uses RED and GREEN light-emit-

• ting 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 pre-

alarm 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.

WARNING

QUICK-FILL SYSTEM OPERATION

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

000psi URC Assembly cannot be used with Quick-Fill

ystem.

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 cylinders. Failure to follow the above warnings may result in serious personal injury or death.

An air mask using the 3000psig URC Assembly without 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 simultaneously; doing so will void NIOSH approval. Failure to follow the above warnings may result in serious personal 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 war approvals of SCBA from MSA are maintained while transfilling air ONL

Y 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 following hose assemblies: 485331, 802687, 802688, 802689, 802690, and 48332, for filling cylinders in IDLH atmospheres.

ting on the SCBA. Be sure that the cylinder valve is fully opened.

b. Remove the rubber dust cap from the female fitting

on the Quick-Fill System hose.

. Push the female fitting on the male fitting until it

naps in place. Pull on the hose to be sure the fit-

ing snapped into place. Transfilling begins when

t the female fitting is snapped on the SCBA male fitting.

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 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 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.

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 HeadsUp 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/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 emer
