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
a
he unit is functional. When the system is pressurized
t
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
i
nit” section for details.
U
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.
