ICM TX UNIT FUNCTIONALITY• The ICM Tx Unit is assembled to the gauge line hoseand serves as the transmitter for the NightFighterHeads-Up Display System.• The ICM Tx Unit turns on automatically when the useropens the SCBA cylinder valve. As the pressurereaches approximately 200 psig, both visible andaudible alarms activate automatically, indicating thatthe unit is functional. When the system is pressurizedabove 25% of the rated service pressure, the alarmenters the Monitor (normal) Mode. The unit remains inMonitor mode until the user shuts off the cylinder airand presses the reset button twice in quick succes-sion.• 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 andthe RED LED on the ICM Tx Unit flashes slowly. Also,during pre-alarm, an ORANGE LED will be displayedin the Nightfighter Receiver. Movement of the unitcancels the pre-alarm.• If the user remains motionless for 30 seconds(approx.), the ICM Tx Unit enters full alarm. During fullalarm, the PASS repeatedly sounds two high-pitchedtones followed by a buzz. During full alarm the REDLED 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 opaquealarm button.• The ICM Tx Unit has three control buttons.o The RESET/OFF (yellow) button resets the devicefrom the full alarmmode. It also shuts the unit offafter the cylinder valve is closed and all air pressureis bled from the unit.o The center opaque lighted alarm button (green/red)activates the full alarm mode with or without airpressure.o The top mode button (green) will refresh the receiverdisplay, set the receiver to continuous mode, andchange the ICM Tx Unit digital display modebetween pressure remaining and calculated servicelife remaining. When the ICM Tx Unit is OFF, themode button (green) can be used to scan an ID Taginto the ICM Tx Unit. See the “Using the ICM TxUnit” section for details.•The PASS function uses RED and GREEN light-emit-ting diodes (LEDs) behind the opaque alarm button todisplay its status visually:o GREEN LEDs start to flash when the cylinder valveis 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 fullalarm.• The ICM Tx Unit operates using four standard AAalkaline 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 Receiver Display.• The ICM Tx Unit has a data logging feature thatrecords information about the SCBA while the ICM TxUnit is turned on. This data log memory can beaccessed using the ICM Tx Reader / ID Tag Writerinterface.• The ICM Tx Unit contains an internal real time clock.This clock can be reset using the ICM Tx Reader / IDTag Writer interface. By default, the internal clock isset to EasternStandard Time. 7TAL 507 (L) Rev. 1 - 10058881

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 beforecharging.7. If filling cylinders in fresh air using the Quick-FillSystem topping off the cylinder is recommended afterthe cylinder has cooled from initial fill. Topping off acylinder after it has cooled will ensure proper servicetime.FILLING INSTRUCTIONS FOR QUICK-FILL SYSTEM1. To connect the Quick-Fill System hose.a. Push the female fitting on the male fitting until itsnaps in place. Pull on the hose to be sure the fit-ting snapped into place.b. Turnthe air source on.If there are leaks from either female fitting, or alongthe 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.a. Remove the rubber dust cap from the male inlet fit-ting on the SCBA. Be sure that the cylinder valve isfully opened.b. Remove the rubber dust cap from the female fittingon the Quick-Fill System hose.c. Push the female fitting on the male fitting until itsnaps in place. Pull on the hose to be sure the fit-ting snapped into place. Transfilling begins whenthe 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 fullservice pressure. After approximately 45-60 seconds,pressure between the secondary air source and the SCBAcylinder will be equal.Cylinder temperature will increase by approximately45°F.The pressuregauge may show FULL immediatelyafter transfilling, but cylinder pressure may decreaseby as much as 190psig after the cylinder cools toroom temperature. Actual service time may bereduced accordingly.3. Compare the SCBA pressure gauge or ICM Unit read-ing to the secondaryair source pressure gauge read-ing. If the readings are the same, pressure is equal.4. Todisconnect the Quick-Fill System hose after trans-filling, pull the gray sleeve back. The hose fitting andthe male fitting will separate. A hiss or pop may beheard as the fittings separate and the high pressure airis sealed off.5. Immediately install the dust cover on the male fitting.6. The SCBA cylinder is ready for service if the cylinderpressure gauge is on the corresponding color band.QUICK-FILL SYSTEM EMERGENCY OPERATIONS1. If you aretransfilling in fresh air and the dust cover willnot 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 atmosphereand the dust cover will not stay on the male fittingbecause air is leaking:a. Immediately reconnect the Quick-Fill System hoseto seal offthe leak and return to fresh air.b. If you cannot reconnect the hose, reach behind andclose the cylinder valve.

The SCBA with the lower pressure is the receiver.Transfilling between users of SCBA should be performedonly during life-threatening emergencies or simulatedtraining exercises. Both donor and receiver must return tofresh air immediately following the procedure.Do not transfill if the donor's audible alarm is ringingor NightFighter Heads-Up Display System/ ICM UnitGauge are flashing. Failure to follow this warning mayresult in shorter escape time to return to fresh air,causing serious personal injury or death.The audible alarmbegins ringing and NightFighter Heads-Up Display System begins flashing to indicate that thepressurein the cylinder has been reduced to 25% of itsrated working pressure. Remaining service time must beused for escape to fresh air. If the donor's audible alarmbegins ringing or NightFighter Heads-Up Display/ICM UnitGauge begins flashing during transfilling, the donor shoulddisconnect and preserve his escape time.1. If the donor's alarm is not ringing or NightFighterHeads-Up Display System/ICM Unit Gauge are notflashing and you have sufficient air to transfill air to areceiver,(greater than 1000psig for Low PressureSCBA and greater than 2000psig for High PressureSCBA), follow these steps.a.
