User's Manual
Note: Refer to chart 2 for the various audible and visual
indicators for the ICM Tx Unit.
Optional ID Tag (PN 10058545), for use with ICM Tx
Unit
Prior to pressurization of
t
he SCBA and during
i
nspection, 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 Receiver will display one
flashing RED LED.
3. When the NightFighter Receiver displays one flashing
RED LED, or when the pressure reaches approximate-
ly 25% of the rated service pressure, return to fresh
air.
Changing the ICM Tx Unit Display Mode
1. Press the top mode button (green) once. This will
momentarily refr
esh the NightFighter Receiver display
as well as light the ICM Tx Unit display.
2. While the ICM Tx Unit display is still lit, press the top
mode button (green) again. This will toggle the display
between remaining cylinder pressure and calculated
r
emaining 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
r
esult in serious personal injur
y 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
o
n the continuation of the average breathing rate over
t
he last three minutes. Increases in the breathing rate
a
fter checking the displayed time may result in less
remaining time than anticipated.
Failure to follow this warning can result in serious per-
sonal injury or death.
Starting Continuous Operations Mode
In Continuous Operations Mode, the life of the batter-
ies in the Nightfighter Receiver will be shortened.
Failure to follow this warning can result in serious per-
sonal injury or death.
Note:
The Continuous Pressure Mode can only be activat-
ed when the system is pressurized. Activate the
Continuous Pressure Mode as follows:
1. Push the top mode button (green) on the ICM Tx Unit
and hold button in for 3 seconds (or push the
Operation Button on the Nightfighter transmitter).
Once LED’s lights come on, release button.
2. Receiver will show air cylinder pressure level. LED
lights will stay on to show air cylinder pressure level
drop.
Turning Continuous Operations Mode OFF
Note:
The Continuous Operations Mode will deactivate if
low batter
y is present.
1. With the ICM Tx Unit in Continuous Operation Mode,
push mode button (gr
een) on the ICM Tx Unit and
hold the button in for 3 seconds (or push the
Operation Button on the Nightfighter transmitter).
Release button once LED lights go off.
2. LEDs will revert to Automatic Mode showing only air
cylinder pressure status at each 25% increment of full
cylinder pr
essure.
Note: The NightFighter Heads-Up Display System will
automatically tur
n itself OFF, approximately 60 seconds
after the apparatus is depressurized. (The single red LED
light will flash at this time).
